T-700 with Cummins was a much better truck if you know how to take care of EGR and DEF system(par for course on ALL new trucks) . The T680 has nowhere near the storage capacity. Quite similar Aero body and the cabinets actually close and stay closed without all the added freightshaker rattle. This is the Kenworth that gave up the lead to Freightliner.
When it came down to order our usual two units per year we had to switch over to the 680's due to the fact that the 660 isn't available anymore. We were hesitant at first because, to be honest, the 680 lost the original Kenworth feel to it and kinda leans over to the; I know it's not cool for me to say but, freightliner feel. I was dead wrong. The 680 has definitely met and exceeded our expectations. We ordered our units with the Paccar MX 485 hp , 13sp manual, and 3:25 rears. We haul fresh produce so we are pulling 80,000 95% of the time. Our 660's with the same specs average 6.8 mpg. Our two 680's are averaging 7.4 mpg.
The 660 was a much better design and looking plastic truck! You can KEEP your crappy 680. Don't want it. Paccar motors are crap and can Only be worked on at a dealer. A Cummins however, can be worked on at most any diesel shop- after the warranty expires. In the long run... an owner will save money with the Cummins. And the fact that this truck is nothing more than a glorified FreightShaker... Well... You can KEEP this piece of Crap!!
@@DieselTrucker2018 Our first holy grail of a truck was a 2009 W900 565 cummins isx 13sp. I loved that truck! It never touched the shop only for brakes, seals, oil change etc. But...but the truck went thru fuel like I owed it child support. 230 gallons in 1100 miles. Compared to 145 gallons on these 680's, what we put in miles a month thats about $3,335.00 in savings a month in fuel. Everything is going up these days insurance, driver pay, maintainence costs etc. So now we need to look at the numbers more than ever, I consider myself old school and I looked at these 680's with disgust like if Kenworth sold out to new disposable style freightliner design. But, things are changing and now you either adapt or die in this business.
@@marcahumada5558 It's a wash. Your always going to get most, if not all that money spent back on trade in with a W900 or a 389. That you paid in fuel. Then there's people who can't drive. And these newer aero trucks are set up for dummy's. Playing the game within a game with boost and the torque curve goes a long way. But they dont teach that to the masses coming out of the mega carrier truck driving schools. Because they are taught on dumbed down equipment. Parameters are set. And that's it.
I've drove trucks with both paccar and cummins motors. I think I'd go with paccar over cummins. To me it shouldn't matter because i baby my trucks as much as possible even as a company driver. why? if you don't care of your truck as much as possible, you'll be spending time in hotel rooms while the truck is being worked on. granted break downs do happen, but, It all depends on how well you take care of your truck. thats just my opinion. On a side note, I'm an avid 680 fan and hope to get one of my own someday lol
Screw it. I'm just going to build a glider with a custom interior, and a balanced C15 with no bs emissions. I'm tired of salesmen telling me they can sell me anything I want, except for what I actually want. If I'm gonna spend that kinda cash on anything, it is going to be exactly what I want down to the last nut, bolt and screw. Oh yeah, and I wont have to wait 9 months for it.
I agree. I bought an older Freightshaker factory specced with CAT C-15 single turbo 6nz serial ## and i will never give it up. I will build it out and get it put in a glider.
@@davids7476 The first truck with turbo-intercooler was a DAF truck in 1971. DAF, you know, the developer of the MX-13 and the second in the European market for 16+ton trucks. It's so bad that PACCAR decided to start a DAF factory in Brazil.
I owe a 2017 T680 and I’ve put 275,000 km on it and so far it’s been great. Only had to don1 software update to correct a EGR problem and Toronto Kenworth didn’t charge me for it. “Part of our customer commitment” I’m averaging 7.6 to 8.3 mpg depending on weight and where I’m going. A big improvement from the T660 with a MX11 I drove before that had constant problems.
My biggest issue with Paccar is the inflated price of parts, 5 years driving so NO ONE can tell me other wise. Every part is at least 25% higher then any other engine maker. Cheapest no air filter change $400 minimum, change all air filters its over $750, for a PM??? Your claiming lower cost, but Paccar proprietary regs won't allow hardly ANYONE but Kenworth to perform mechanicals. At $185 per hour with minimum 2 hours your paying over $300 for a tech to hook a computer up and diagnose. 10 minutes of work $300+. So yeah it may have some benefits but as a owner Operator for 5 years on 2 different T680s, maintenance and mechanicals are not cheap. One more example, the Indel B refrigerator is $1400 to replace vs the $500 or less side open door style ANY brand. I could go on and on comparing part to part on dozens of parts. Not enough time.
I am thinking of buying a decent used truck in 6 to 8 months and an owner operator told me to buy a Cummins equipped truck just for that issue! Maintenance cost. Thank you for your posting.
That Collision mitigation sucks every time you go under a bridge or overhead sign you have to worry about the truck applying the brakes thinking your going to be involved in an accident I am starting to get PTSD because of that crash mitigation device it seems objects that are not there if you try to do a lane change it will lock up the brakes on you and most likely cause an accident that crash mitigation should be gotten rid of
Keith Jentsch my Toyota pick does that under bridges or shade. It’s scary. I could only imagine riding at highway speeds with a big truck doing that. No thanks.
My golf pulls crap just like that too, vehicle int he lane beside could be slowing down and my golf will just hammer on the brakes. worst part is if you turn it off you lose cruise and other features that dont have anything to do with the collision avoidance system. Another thing that bothers me with new vehicles is the peterbilt 579 I drove would cut throttle and hit the brakes if you took a corner fast.....well on ice thats a big f'ing no no its almost caused me to wreck several times. These modern driving "aids" need to be banned.
I've always said I trust my driving skills much more than some stupid computer having control enough to actually apply brakes or try to steer on its own
The dealers praise this engine when they try and sell you one. When you try and trade it in they tell you cause it’s a Mx it has crap resale so they can only offer you peanuts in trade value. Nothing like a car salesmen selling a semi truck.
THat is the case with the older MX engines......but that's any older engine. 2010-2013 engines all have crab resale value.....take a peek on Truckpaper.com and see for yourself.
@@KenworthofRichfield not sure if I'd compare it to any. The MX was a touch better than the ultra dependable Maxx Force, but still nowhere near a DD 13 or even an ISX. If PACCAR really has it dialed in this time around, it'll show in the trade in/resale in just a couple of years though. Judging by the quality of their trucks, I'm sure they'll work it out.
At 8:50. "This is one of the best engine options .... " Of course, it's a European engine from the Netherlands. As you all know: it ain't much if it ain't Dutch. The MX-13 is developed by DAF Trucks at Brainport Eindhoven, The Netherlands. We do more than growing tulips.
Yes you do! I love this engine. It's interesting to see the divide and what engines the like in their trucks tells you what engine they want in their car also. (Hint, it's usually old)
@@pecheur1951 The Swedish superiority doesn't exist on the European market. No. 1 Mercedes no. 2 DAF no. 3 MAN no. 4 Volvo no. 5 Scania. PACCAR is a great company with their great daughters Kenworth, Peterbilt and DAF. The future for DAF in Brazil looks more than good, which might bring a new V8.
These T680's are some great trucks. We have 2 in the fleet and the boss has a 3rd one that came in last Monday at the dealership. Your statement about good drivers being able to adapt is so true. The Mx through the years has been updated and it been for good reasons, keeps getting better. I can see the difference and changes from our 1st one back in 2014 to the newer ones we got this year. Currently in my 2nd T880 with the MX that I've had since the beginning of 2016 and it's going on 4 years and over 200k and it's only had the crankcase ventilation module replaced and 3 software updates. It may not be the 565 or 605 Cummins, but it holds its own to other engines that are similar to it. My old T800 with a C15 wouldn't even like running below 1200 rpms where the MX will go to 1000 on the 500 and 510 versions. Great video as always and I'll look forward to the next one.
Love my paccar engine,drove the DAF in Europe same engine. My son is still driving in Europe,gess what he is driving yep a DAF super space can with a paccar 510. Think it is in the family
@@josephvalentine7 I have absolutely no problems with my paccar engine, all the problems I've heard are in the first gen which there always in, or poor drivers. I actually really like mine, it's not a 15L no but it's a strong puller.
We have 8 2017s with paccar mx 13s 4 specd one way 4 specd another and 4 of them specd for grossing heavy will out pull any new Detroit or Volvo no problem even when they are grossed and we only have one that has had any issues that put it oos for anytime and really that was because the driver didn't keep up with maintenance and just beat it to hell
@@charlesedinger3063 I believe you on the dd15 but I’d put money I’d drag that mx13 up a hill With my d13 lol . I have yet to be passed up on the hills by any Mx motor .
paccar sucks and I will never ever ever buy another one. I can't believe these guys are still pushing carbage out on the road. less down time my ass. buy this truck and go strait to the poor house. I don't care what the slick salesman says, buyer be ware these engines are trash.
You should talk about all the plastic parts on the motor. Especially the ones that get hot and cold and then brittle over time and crack. That’s a great sales pitch. Let’s not forget about the time it takes to replace said brittle plastic parts at the dealers. This truck is nothing more then an upgraded retirement package for today’s new mechanics. It guarantees their long future employment at their local dealer.
You do realize that they have been using plastic parts in the automotive industry for decades without any real issues. Yea sure it may deteriorate over the years but so does any metal.
Thanks Steven!!!! I kinda feel that the "salesman" thing is dead. I'm here to help educate and get people the things that will help their business thrive!
Great truck, have one myself, but 2014 model year. The question that I have is does anybody actually run 75k miles between oil changes? I do mine every 25k with full synthetic oil just bc I think 75k is too much. No hate or bs, just curious.
2 yr 250k warranty! That's a disaster waiting to happen! I'm not paying extra for a longer warranty! Unless its reasonable! If paccar engines are now dependable why doesn't their warranty reflect that? It needs a 4-5 year standard no deductible.
From a mechanics view these paccar engine and transmission are garbage. Fuel system is a joke for troubleshooting, half the time the unit pumps are on back order. Plastic cooling fittings on right side of the block break. Def level/ quality sensor always on back order. Turbo vgts always fail. On the paccar transmission the shift levers always have internal failures. Paccar has a recall on mx13 engines because of wrist pins on the piston not fully seated. when the warranty runs out you are screwed. I have seen a hand full of these plastic oil pans cracked, they crack right by the drain plug. Stick with a cummins isx and Eaton
I don't think Cummins and Eaton are exempt from having issues as well. I'm sure if Paccar sees a issue that they address it and make improvements. As of now I have no issues with my MX.
Thanks for the info Josh. I'm an old school dude, started driving in 78. I remember when the PACCAR motor first came out. And like all new things, there were bugs. I actually learned a lot from this video and now will keep this as a viable option to buy the PACCAR combo. I love your videos and you not only make me laugh, ya make me learn. Thanks so much
Have been a owner operator for 10 years, first had an 95W900L with a CAT C-15 loved that truck until CA laws with emissions being from CA had to get into a newer model, purchased an early model 2011 T660 with an MX13, if I am correct it was the first model of the MX13 to ever come out, truck was used with 300,000miles and was great up until 500,000 because of no engine problem but problems with Emissions system, my technician did an emissions delete on and over road the ECM, truck is was at 875,000 when we lost her in a roll over, besides the emissions crap great engine
Paccar engines are not for US. Americans like to rev it high and we can already see what happen for those engines if the truck has manual transmission - most of the paccar engines break extremely quickly. Once they learn that an engine can actually rev from 1000 to 1500 rpm, its gonna be a much better engine for NA market.
wow ppl are making up a lot of shit in these comments lol. No engine is without issue. Ford stopped buying international motors, international stopped making maxxforce, they stopped building the Mercedes engine. What I'm getting at is if paccar motors were actually as bad as people claim they would've stopped making them already. 2010-2020. That's a decade folks. I haven't had one single issue out of my paccar engine. Only thing I wish is it was a 15 liter engine instead of a 13. People like what they like though. People always pumping up cat and cummins. I've passed a number of those engines on the shoulder with oil all over the valve cover. Why did they stop putting cat engines in trucks and why did cat get slapped with a class action lawsuit for selling engines with defective blocks??? I'm just saying.....
I feel this man drives for swift and never has heard of the past I had a T680 with a paccar MX-13 only lasted for 400,000 miles but I still have my first truck I started trucking a 1999 FLD 120 with a 6NZ boy if I tell you is one of the most reliable truck is has 2,500,000 miles and has cost me 3/4 less then the T680 paccar will never be as good as Detroit Diesel or Cummins and Cat the reason cat stop making engines is because they couldn’t not meet today’s EPA requirements all the Bullshit that California wanted a fellow trucker of mines has a 2011 Peterbilt 386 remove the EGR DPF boi that Cat C13 change I made more power and the engine was a 2006 engine before that bs of DPF started that engine was made to run with out a DPF what you need to do is go and stop believing that the Paccar bs shit is going to be good it will never be as good as other Diesel engines in the market do your research why the ware defective blocks and once you do that STOP TALKING SHIT OF THE BIG 3 o hold up you want the Answer why Cat had defective blocks ooo I got you is cus they could keep up with the new emissions of the EPA
B M Like I said ppl like what they like. Paccar is nothing more than a Cross between a Cummins and a cat. More so the Cummins. Many of the Cummins paccar parts interchange. I’m glad your truck has 2.5 million miles but most ppl don’t keep a truck that long. Your right it will never be as good as any of the engines you love but that does not mean they will stop making them.....
I drive for one of the biggest and best trucking companies... My favorite truck right now is the Peterbilt 579, but my company has stopped using the 579 and the T680 because of electrical problems. So when I make my truck purchase I have to go with a reliable Freightliner that you see to many of on the road... But as I said I LOVE the 579, but it would not be the best choice for my truck purchase... I hope one day they get it right
I like how you brought up the reversing with the automatic transmission issue i mentioned in your last video is their a "creep mode" like that i can get on my ultra shift? I love my mx13 btw great engine and i think the 485 hp 1700 tq is the perfect balance of power and efficiency I'm pulling steep mountain grades at 35mph and still getting 8-10 mpg when cruising on flats
@@redwing1273 The oldest Paccar Mx engine in my bosses fleet is a few trucks that are 2016 models that were purchased in 2015 and those trucks are still running with over 500k and no issues with the actual engine. It always seems to be the emissions-system with these trucks.
@@ItalianStallion1415 Then you must not have experience because simply lifting your foot off the brake and applying pressure to it again to stop as you back up is as easy as pie and response time to stop is also better. Moving your foot from the brake to the gas and back to brake is obviously not as easy, which is the reason "why" it's nice. In your experience. Amazing.
Man... the comment are not good for this engine. Sounds like it's $3500 cheaper on the front end but $15,000 more on the back end. The only way I would try this from the comments is if they covered the unit fully for the 5 years I'd own / lease it. No need to risk my hard earned money. I'd let them risk their's however.
I'll stick with my 98 t600 Detroit 12.7 paper trk. I just put a new engine in it 33k. It's like a 98 glider, no gd def 150 sensors bs. Def trucks are not dependable...
Sounds like e everyone's complaints are from older paccar engines. What about the newer ones. And i love how people say cummins dont have reliability problems . Of course they do . Cummins problems are there loud as shit and are about as refined as a cement mixer and get sht gas mileage. Its time for cummins to put some technology back into there engines . Cast iron is antique technology. There are much stronger metals out there. But these companys use cast iron because its cheap to manufacture..
Some great points Robert. The Paccar engines came out at the same time as the emissions standards changed. You know....the standards that almost bankrupted International and put Cat totally out of the game. The fact that these engines ended up making it through that and work as well as they do......it's a great thing. Guys that don't like them are running 10 years behind the game.
I want to be more confident with my EPA 13 mx13. I've had the MIL light on and stop engine light flash for months and techs and other owners say its normal.
@@Tharus Battery voltage is such a key and also check connections to make sure that there's no "green" in them. Any water intrusion can spell big problems. I know that generation did have an issue with that.
I would not buy a paccar Benjamin product They don't have cards when the truck goes down. I know I've been waiting 12 weeks for an ECM. I am one truck company, I have no business now. Thank you,
Jb 2019 I drive the all mighty cummins isx that didn't make it to a million miles and its got less than 100k on it and its leaking oil out of the heads and exhaust bolts and manifolds broke after cummins did the rebuild. Cummins arent any better than any other engine out there other than having the go to name that some people are sucked in by.
Have you seen this type of T680? This is a BADDDD ASSSS T680 2020 KENWORTH T680 | MHC Truck Sales - i0434395 mhc.com/trucks/new/2020/kenworth/t680/i0434395
I didn’t even know Paccar made engines until today, shows you what I know. I really miss the Pre Emissions CAT motors. But alas those are gone for good. I haven’t given a paccar engine a try yet but I would like too. I’m running a T-800 with a Cummins ISX in it, can’t complain. As long as it’s not a POS Mercedes I’m happy for the most part. Every Mercedes truck I ever had was JUNK
It's a great engine. It's a derivative of the DAF engine that's been used in Europe for years. There are a ton of great features engineered into it for longevity.
@@KenworthofRichfield Sophisticated engine with more power per Liter (gallon) and less noise. See this video that's showing the MX-13 doing its job in the rural areas of Brazil.
How much horse power can be pumped up to on m13 for bull rack hauling. Fuel mileage means little in this field. Miss the T600 cab truck, although being 6,2 I do not think I would fit in it at 300 lbs now days vs 180 at 22 years old. Just seemed tight but that model made me a Kenworth guy. Loved that extreme sloped hood. Do not like green color at all.
mx13 are great but there is almost no service on the road exepct dealer ... no major truckstop shop work on mx13 make it real hard to fix ... and dealership have wait list.. most of the time until they get as much service as a cummins or a detroit i don,t think people will shift toward it
Having driven a paccar an isx and an mp8 mack motor. The paccar is hands down my favorite. Its smooth at any rpm, I do however have to disagree with the peak torque rpm. From personal experience it seems to love running the top half of the rpm range with shifting around 1500 vs the 1000 the auto trans wants to shift at. The ones I've ran have been 430-455hp and will walk away from a 500hp DD15. I'm honestly surprised that at 500hp the torque number is up there with the X15 despite being smaller. I will say that if this engine didnt have the emissions junk on it that we are forced to have then they would be an excellent engine.
The 500 hp Paccar definitely has a lil more fuel going to it versus the 455. My first T880 W/ the Paccar 455 definitely had a little bit less going to it compared to my current 500 just by comparing the info on the engine data plates. I've had my Paccar as long side the DD 13, Volvo's 13L and Mack's as well and it pulled right along and in most cases passed on by them. I have a 18 spd manual behind mine and I run it down to 1000 rpms before having to drop down a gear. Heck, some hills I'll have to up shift cause the rpms will get over 1500 and I try to keep it within the peak torque and she pulls right along. We have trucks with the 455 and Allison 6 spds and I'll pull away from those trucks.
Our company runs MX13 for 1 reason , we lease all our equipment if it blows an engine who cares it's under warranty ... if we actually bought our equipment yeah it's for sure going to have a 550 x15 Cummins performance series
I’m driving a company truck peterbilt 2018 589 with mx13, put 350k on it no engine issues yet!!! With that being said I’m looking into buying my own truck and dispite my great experience I would be worried to buy the same equipment if I had to pay the repair bills because of the horror stories I read about.
The biggest problem I have with the paccar engine is lack of dealer training etc ..... Every time I've ever had a problem with a check engine light / engine shut down I've had to continuously take the truck to the dealer due to the simple fact that outside repair shops don't have access to Davie or similar software. 9 times out of 10 this meant multiple return visits back to the dealer most of the time my driver or I would make it about 5 mi down the road before the engine shut down lite would return ... Multiple problems with wiring harnesses for the emissions that I was stuck paying for until someone informed me that there was a service bulletin or recall after I spent thousands of chasing ghost repairs. Then there was the EGR valve repair which normally I could have done myself except for the simple fact the quick connects for the coolant lines on the EGR never worked properly and dealership informed me that there's a retrofit kit and I'd be looking at about $4,000+ for a simple EGR valve ..... I bought used EGR valve and a brass compression fitting fix that... Then there was a problem with horsepower multiple times I was told that the engines had a 500 horsepower rating let's just cut that in half and that's about the performance I received out of the mx-13 engine.
Sorry, no Collision system for me, nothing touches the brakes but me, because i'm not taking a chance on a false reading to wreck me & then i'm screwed! Because the DOT is not going to Cite the system, they will cite me!
I drove a brand new (less than 1,000 miles on it) 579 with the mx13 a year ago. It was a fleet spec so it was probably the lower power unit. What a turd that truck was. I'll stick with a c15 6nz and 13 speed manual. Night and day. I never struggle with the old 379. I run 76,000 to 79,500 most of the time with no issues. That mx13 579 was struggling at 50,000 plus. Under that and it got great fuel millage so there's that.
Paccar engines are my first choice no doubt. Spent many years driving Paccar vehicles in Europe ( DAF ) before coming to the States via Canada. I would recommend Paccar any time....
When you say you drove all of it in europe ..that engine was good without the emissions...right now not only parts are 25% higher but they started to put plastic or composite that crack easier on the engine ..if you switch truck every 2 to 3 years chance are you won't see those failure so ...but passed that more stuff coming to break
I ran a 579 with a mx13. It made damn good fuel mileage but was a pain to get serviced on the road. Few places had filters and shit for it. If the KW mitigation system is anything like Pete (i would assume they are since they're both owned by paccar), then you'll NEVER get used to it slamming your brakes while you pass a road sign or drive under a bridge. That system almost gave me PTSD and made me scared to drive the truck anymore.
I work for the company with the brown trucks. My 2019 T680 has been back to the dealer 4 times for engine problems. My terminal has 30 new T680’s with the paccar engine and transmissions. All but 4 have been back to the dealer for engine problems. One of them is at Kenworth now for the 7th time. Don’t buy a paccar motor if you plan on driving the truck more than a few miles before bringing it in for an engine light on the dash. The collision mitigation systems are absolutely dangerous as well. The T680 with a X15 Cummins and an Ultrashift or standard transmission would be a great truck.
@@dutchman2506 I agree the states has shit drivers that cant even drive on freeways and there not even that heavy. Our mx13z were loaded upto 58t 128000lbs and with our steep grades and windy roads if you know nz roads . Some lasted upto 1 million kms
Cummins over paccar.. there's a night and day different in performance. Cummins is way more reliable and can take a beating.. if you're over the road... but if you're not doing long huals just a local tri state driver your should be fine with routine maintenance
Virgil, There's actually a ton that will go into that in terms of what you're carrying, what trerrain, etc. A 3.36 is usually a good, conservative gear ratio that's balanced between performance and mileage.
The 3.36 is a great ratio for the old cats and Cummins. On my old trucks, that would give me 1350 rpm at 65. The newer engines are designed to get their best mileage at much lower rpm, so a taller gear would likely be better.
Bad experience with 2014 t680 and 2017 t680 With paccar engine Eaton 13 speed automatic Shifting is very bad Change few software's but its same shit I like interior design but quality is not good it makes rattle noises from hood roof and dash Its not quite trust me come drive mine its also green! SERVICE bad bad bad bad
Auto transmissions are still junk, the only company thats got a decent one is volvo. I had more break downs because of the auto trans then the emissions surprisingly with my old kenworth piece of junk
Im running a 2017 t-680 with 300k miles on it ..... I'm on knock sensor number 4. I've got over 25k in the aftertreatment system. all I keep hearing from the dealership as that's not covered under the 500000 mile warranty. I keep having stupid electrical issues. My advice to everyone Freightliner gets better fuel mileage and has way more options out on the road for service. All you have to sacrifice is a little bit of interior amenities. Stay away from the mx-13 from experience
880 hood is a little more squared up the headlights are different. 880 only comes in daycab or midroof sleeper no condo. From the firewall back they are identical T880=T800 T680=T660
I am in business to make money, you can sell the PACCAR to the dummies that don't do any re search but I for one will not work to pay off a truck that in the end has the worst resale value in the industry. Get on Autotrader find 2 KW with comparable specs one Cummins and one PACCAR. Look at the price. Isually $15,000 to $20,000 difference. The PACCAR is done after about 300k miles, after that NOBODY wants it.
Older Paccar engines got a bad rap. Especially because they came out at the wrong time. You know....the time that almost put international out of business and the time that made Cat stop making truck engines. :D There are reasons as to why we have both engines available. In the same sense, the Paccar has great longevity.
Weird, but the Paccar MX engines are known as reliable engines in EU. I suspect Paccar adapted the MX for the US market. In EU max hp 530 in the US 510 for example..it even sounds different
I debating talking about that Jesse. That engine came out at the worst time! When you think about it, that's the timing that put Cat out of the road going business and almost put International totally out of business.
I’ve owned a 2015 680 with a Cummins, I bought a new engine for it around 800k miles. The new ISX got put in and I was still in the shop constantly, so I ended up selling my truck because it was killing me. I’m thinking about buying a used one with a Paccar but scared to pull the trigger from all the bad rap I’ve heard over the years, the year I’m looking at is 2020 with MX13
OK where do I begin first off the Detroit 60 series has used composite oil pans and valve covers forever so that is nothing new at all. As far as that adaptive cruise system as some call it its a accident waiting to happen I know it almost happened to me. Going west down I-70 into Utah icy roads during a snowstorm a cardboard box blew in front of the truck was doing 30 mph it decided to lockup the brakes ALMOST jackknifed the truck 30 years experience otr prevented that from happening. 2.79 rears? What are you hauling paper towels and toilet paper the engine is still 12.9 liters isn't it? Its a flat lander truck pure and simple. I have a 2016 589 Peterbuilt with a MX 13 in it 13 speed 3.21rears and I'm glad you all decided to change the valving on the egr and turbo because your old way of doing it well its junk. Loves to do what I call backfire through the turbo and egr which by the way messes up the $6000.00 turbo if its not set right. And almost ALL of them do it driven about 4 MX-13s and everyone did it? OK I will take it to the shop and get it fixed sure if you can afford a 2 week wait period to get it in sometimes its only a week you forgot to mention that. Oh yeah you also forgot to mention that if you want to have it turned up at the dealer lets say 450Hp to 500HP it cost about $5000.00 dollars that's just so the factory and send the download to the shop and program the ecm! Thank goodness there are plenty of places to get it done at a fraction of the price. Everything I have said is a FACT but one thing I have not talked about is the oil changes every 75.000 miles no way would I ever do that I'm 79.000 lbs+ all the time and a lot of mountain driving I change it every 25.000 and every time its black as coal and like water. Now I fixed all the above problems myself and have not one problem since 80.000lbs flat land 7.5mpg mountains averages about 4.5 to 5.2 does not burn a drop of oil and tons of low end torque at 550 HP and will pass emissions wonder how that happened?
Kenworth of Richfield ok so u must be referring to the new paccar motors after they fixed all the kinks? I believe it too bcuz the new x15 cummins jakes are pretty strong too! Mattafact ive driven a new paccar now that I remember and yes they are pretty strong so yeah u are right!
Sorry to be negatively but you CANNOT get me to adapt to the collision system. My truck has it now and this things brakes for shadows that's on the road. Its extremely dangerous and since you added fuel mileage, please tell the consumer that it adapts to the slower speeds of traffic in front of you. So if its slowing down and uor having to pass, your burning more fuel to speed up.
Jacob, I'm going to have to call the BS on the "shadows" part. It uses radar/lidar setups....neither of which see shadows. Now, I have heard that there has been a "ghost" braking incident. This is usually caused by a mis-adjusted radar/lidar setup. Check with your dealership and get that setup correctly and it should help you out quite a bit.
Get a glider of that, and drop in a freshly built 8V91 Detroit silver, or go bold and drop a 12V91 Detroit Silver in it. You might get your man card back, and people will stop calling you Dorthy all the time.. 18 or 13 Man-ual required. Oh, and no day glow lime green. It should be illegal.
It is a nice engine for sure. I have driven the MX-13 in a KW AND a DAF XF (euro truck) and way WAY better than the um ...... Maxxforce engine Internationals.... Remember those? I'm trying to forget them.
My oil pan cracked 2 weeks ago at 96k the dealer told me they had some bad batches made and I was the luck winner! They took care of it warranty no issues. Still love my PACCAR
The MX13 is a bag of shit!!! I have the same engine in a DAF 106,European truck,and I've had nothing but trouble with it...oh,and these engines have 3 fuel pumps....!!!
@@KenworthofRichfield .injectors failure,oil seals,(pissing oil out) oil sump seal failure, fuel pumps..but this engine is in a DAF 106,and its 510hp....
Paccar MX-13 ....A lightweight heavy-build 13L engine built not by iron steel but by highly-compressed composite graphite. An amazing technology that is excellent at displacing heat, lasting longer between oil changes and most importantly ......weighs in more than 400lbs less than the legendary Cummins 15L workhorse.
Been a T-680 fan since day one to 5 years later on it’s the holy grail and you can’t never go wrong 👍🏾🙏🏿🙏🏿
T-700 with Cummins was a much better truck if you know how to take care of EGR and DEF system(par for course on ALL new trucks) . The T680 has nowhere near the storage capacity. Quite similar Aero body and the cabinets actually close and stay closed without all the added freightshaker rattle. This is the Kenworth that gave up the lead to Freightliner.
When it came down to order our usual two units per year we had to switch over to the 680's due to the fact that the 660 isn't available anymore. We were hesitant at first because, to be honest, the 680 lost the original Kenworth feel to it and kinda leans over to the; I know it's not cool for me to say but, freightliner feel. I was dead wrong. The 680 has definitely met and exceeded our expectations. We ordered our units with the Paccar MX 485 hp , 13sp manual, and 3:25 rears. We haul fresh produce so we are pulling 80,000 95% of the time. Our 660's with the same specs average 6.8 mpg. Our two 680's are averaging 7.4 mpg.
The 660 was a much better design and looking plastic truck! You can KEEP your crappy 680. Don't want it. Paccar motors are crap and can Only be worked on at a dealer. A Cummins however, can be worked on at most any diesel shop- after the warranty expires. In the long run... an owner will save money with the Cummins. And the fact that this truck is nothing more than a glorified FreightShaker... Well... You can KEEP this piece of Crap!!
@@DieselTrucker2018 Our first holy grail of a truck was a 2009 W900 565 cummins isx 13sp. I loved that truck! It never touched the shop only for brakes, seals, oil change etc. But...but the truck went thru fuel like I owed it child support. 230 gallons in 1100 miles. Compared to 145 gallons on these 680's, what we put in miles a month thats about $3,335.00 in savings a month in fuel. Everything is going up these days insurance, driver pay, maintainence costs etc. So now we need to look at the numbers more than ever, I consider myself old school and I looked at these 680's with disgust like if Kenworth sold out to new disposable style freightliner design. But, things are changing and now you either adapt or die in this business.
Look in the Truck Paper and you will see 99.9% of all engines rebuilt are the Cummins. Reliable? Hell no.
@@marcahumada5558 It's a wash. Your always going to get most, if not all that money spent back on trade in with a W900 or a 389. That you paid in fuel. Then there's people who can't drive. And these newer aero trucks are set up for dummy's. Playing the game within a game with boost and the torque curve goes a long way. But they dont teach that to the masses coming out of the mega carrier truck driving schools. Because they are taught on dumbed down equipment. Parameters are set. And that's it.
@@DieselTrucker2018 wow what a load of bull. You really do not have a clue about trucks or the paccar brand. Dick head
I've drove trucks with both paccar and cummins motors. I think I'd go with paccar over cummins. To me it shouldn't matter because i baby my trucks as much as possible even as a company driver. why? if you don't care of your truck as much as possible, you'll be spending time in hotel rooms while the truck is being worked on. granted break downs do happen, but, It all depends on how well you take care of your truck. thats just my opinion.
On a side note, I'm an avid 680 fan and hope to get one of my own someday lol
Screw it. I'm just going to build a glider with a custom interior, and a balanced C15 with no bs emissions. I'm tired of salesmen telling me they can sell me anything I want, except for what I actually want. If I'm gonna spend that kinda cash on anything, it is going to be exactly what I want down to the last nut, bolt and screw. Oh yeah, and I wont have to wait 9 months for it.
I agree. I bought an older Freightshaker factory specced with CAT C-15 single turbo 6nz serial ## and i will never give it up. I will build it out and get it put in a glider.
You can’t build a glider anymore you have to buy whatever it’s in the market that they haven’t sold

I owe a 2017 T680 and I’ve put 275,000 km on it and so far it’s been great. Only had to don1 software update to correct a EGR problem and Toronto Kenworth didn’t charge me for it. “Part of our customer commitment” I’m averaging 7.6 to 8.3 mpg depending on weight and where I’m going. A big improvement from the T660 with a MX11 I drove before that had constant problems.
they are selling me a 2017 t680 with 360kmiles for 40k i'm thinking of getting it with a paccar mc13 what do you think ?
My biggest issue with Paccar is the inflated price of parts, 5 years driving so NO ONE can tell me other wise. Every part is at least 25% higher then any other engine maker. Cheapest no air filter change $400 minimum, change all air filters its over $750, for a PM??? Your claiming lower cost, but Paccar proprietary regs won't allow hardly ANYONE but Kenworth to perform mechanicals. At $185 per hour with minimum 2 hours your paying over $300 for a tech to hook a computer up and diagnose. 10 minutes of work $300+. So yeah it may have some benefits but as a owner Operator for 5 years on 2 different T680s, maintenance and mechanicals are not cheap. One more example, the Indel B refrigerator is $1400 to replace vs the $500 or less side open door style ANY brand. I could go on and on comparing part to part on dozens of parts. Not enough time.
...you ...FORGOT about ...''MACK''...MACK...take it BACK...to '''MACK...that''s their ...motto...
Inflated parts cost plus lower resale value, great recipe for failure in this industry.
Way to expensive to service
Sound like a dealer issue
I am thinking of buying a decent used truck in 6 to 8 months and an owner operator told me to buy a Cummins equipped truck just for that issue! Maintenance cost. Thank you for your posting.
That Collision mitigation sucks every time you go under a bridge or overhead sign you have to worry about the truck applying the brakes thinking your going to be involved in an accident I am starting to get PTSD because of that crash mitigation device it seems objects that are not there if you try to do a lane change it will lock up the brakes on you and most likely cause an accident that crash mitigation should be gotten rid of
Keith Jentsch my Toyota pick does that under bridges or shade. It’s scary. I could only imagine riding at highway speeds with a big truck doing that.
No thanks.
My golf pulls crap just like that too, vehicle int he lane beside could be slowing down and my golf will just hammer on the brakes. worst part is if you turn it off you lose cruise and other features that dont have anything to do with the collision avoidance system. Another thing that bothers me with new vehicles is the peterbilt 579 I drove would cut throttle and hit the brakes if you took a corner fast.....well on ice thats a big f'ing no no its almost caused me to wreck several times. These modern driving "aids" need to be banned.
Pull the fuse
At least my wife's Mazda CX9 only has lights in the mirrors to annoy me first thing I do is push the button to disable it
I've always said I trust my driving skills much more than some stupid computer having control enough to actually apply brakes or try to steer on its own
The dealers praise this engine when they try and sell you one.
When you try and trade it in they tell you cause it’s a Mx it has crap resale so they can only offer you peanuts in trade value.
Nothing like a car salesmen selling a semi truck.
THat is the case with the older MX engines......but that's any older engine. 2010-2013 engines all have crab resale value.....take a peek on Truckpaper.com and see for yourself.
@@KenworthofRichfield not sure if I'd compare it to any. The MX was a touch better than the ultra dependable Maxx Force, but still nowhere near a DD 13 or even an ISX. If PACCAR really has it dialed in this time around, it'll show in the trade in/resale in just a couple of years though. Judging by the quality of their trucks, I'm sure they'll work it out.
Yup, resale is junk MX is a disposable investment
@@KenworthofRichfield
What is the best year on this engine if buying a used truck?
@@stevenbrewer7314 It's very much the case of the newer the better. Paccar has done a great job of making small improvements along the way.
T680 was my first truck.. no complaints but it was an automatic... if I ever get another one it will have to be manual
At 8:50. "This is one of the best engine options .... " Of course, it's a European engine from the Netherlands. As you all know: it ain't much if it ain't Dutch. The MX-13 is developed by DAF Trucks at Brainport Eindhoven, The Netherlands. We do more than growing tulips.
Yes you do! I love this engine. It's interesting to see the divide and what engines the like in their trucks tells you what engine they want in their car also. (Hint, it's usually old)
DAF should build a nice V8 to stop those Swedes feeling superior 😆
@@pecheur1951 The Swedish superiority doesn't exist on the European market. No. 1 Mercedes no. 2 DAF no. 3 MAN no. 4 Volvo no. 5 Scania.
PACCAR is a great company with their great daughters Kenworth, Peterbilt and DAF. The future for DAF in Brazil looks more than good, which might bring a new V8.
I like how Animated this Guy is. I like Peterbilt Steve also, but this guy makes you want to Blow 180k on a Brand New Truck.
Thank you!!!!! I do what I can!!!!
Not my color but if I ever pull reefer I know what I'm getting, love the jump studs on the back. Awesome idea
These T680's are some great trucks. We have 2 in the fleet and the boss has a 3rd one that came in last Monday at the dealership. Your statement about good drivers being able to adapt is so true. The Mx through the years has been updated and it been for good reasons, keeps getting better. I can see the difference and changes from our 1st one back in 2014 to the newer ones we got this year. Currently in my 2nd T880 with the MX that I've had since the beginning of 2016 and it's going on 4 years and over 200k and it's only had the crankcase ventilation module replaced and 3 software updates. It may not be the 565 or 605 Cummins, but it holds its own to other engines that are similar to it. My old T800 with a C15 wouldn't even like running below 1200 rpms where the MX will go to 1000 on the 500 and 510 versions. Great video as always and I'll look forward to the next one.
Thanks Wayne!!!! Always great to hear from you!

The MX-13 is a DAF engine rebadged to her mother PACCAR.
Paccar as good as as any engine on the market. But there will always be people who have a different opinion.

Yeah, the engine is called PACCAR after the mother of DAF.

You should talk about all the plastic parts on the motor. Especially the ones that get hot and cold and then brittle over time and crack.
That’s a great sales pitch. Let’s not forget about the time it takes to replace said brittle plastic parts at the dealers.
This truck is nothing more then an upgraded retirement package for today’s new mechanics. It guarantees their long future employment at their local dealer.

@@joeybenton8986 Right on!
Great truck, have one myself, but 2014 model year.
The question that I have is does anybody actually run 75k miles between oil changes? I do mine every 25k with full synthetic oil just bc I think 75k is too much.
No hate or bs, just curious.
2 yr 250k warranty! That's a disaster waiting to happen! I'm not paying extra for a longer warranty! Unless its reasonable! If paccar engines are now dependable why doesn't their warranty reflect that? It needs a 4-5 year standard no deductible.
I love the paccar mx13 engine, the only thing better is the mx 11. just as torquey as mx 13 ,400 pounds lighter and even better fuel economy.
We're starting to see more and more of those engines hitting the road which is great!
From a mechanics view these paccar engine and transmission are garbage. Fuel system is a joke for troubleshooting, half the time the unit pumps are on back order. Plastic cooling fittings on right side of the block break. Def level/ quality sensor always on back order. Turbo vgts always fail. On the paccar transmission the shift levers always have internal failures. Paccar has a recall on mx13 engines because of wrist pins on the piston not fully seated. when the warranty runs out you are screwed. I have seen a hand full of these plastic oil pans cracked, they crack right by the drain plug. Stick with a cummins isx and Eaton
I don't think Cummins and Eaton are exempt from having issues as well. I'm sure if Paccar sees a issue that they address it and make improvements. As of now I have no issues with my MX.
What Wayne said
Of course stupid mechanics cant fix paccar. You have to be smart to fix paccar
Thanks for the info Josh. I'm an old school dude, started driving in 78. I remember when the PACCAR motor first came out. And like all new things, there were bugs. I actually learned a lot from this video and now will keep this as a viable option to buy the PACCAR combo. I love your videos and you not only make me laugh, ya make me learn. Thanks so much
Thank you and the laugh/learn combo is what I'm going for. Glad I was able to get it!
So when did the paccar come out?

Please turn off the music way do you do it.
Have been a owner operator for 10 years, first had an 95W900L with a CAT C-15 loved that truck until CA laws with emissions being from CA had to get into a newer model, purchased an early model 2011 T660 with an MX13, if I am correct it was the first model of the MX13 to ever come out, truck was used with 300,000miles and was great up until 500,000 because of no engine problem but problems with Emissions system, my technician did an emissions delete on and over road the ECM, truck is was at 875,000 when we lost her in a roll over, besides the emissions crap great engine
Paccar engines are not for US. Americans like to rev it high and we can already see what happen for those engines if the truck has manual transmission - most of the paccar engines break extremely quickly. Once they learn that an engine can actually rev from 1000 to 1500 rpm, its gonna be a much better engine for NA market.
The Paccar engine will rev, but it's pointless to do it. THis is a driver issue and not an engine issue to me.
wow ppl are making up a lot of shit in these comments lol. No engine is without issue. Ford stopped buying international motors, international stopped making maxxforce, they stopped building the Mercedes engine. What I'm getting at is if paccar motors were actually as bad as people claim they would've stopped making them already. 2010-2020. That's a decade folks. I haven't had one single issue out of my paccar engine. Only thing I wish is it was a 15 liter engine instead of a 13.
People like what they like though. People always pumping up cat and cummins. I've passed a number of those engines on the shoulder with oil all over the valve cover. Why did they stop putting cat engines in trucks and why did cat get slapped with a class action lawsuit for selling engines with defective blocks??? I'm just saying.....
Funny how brand loyalty can cloud some vision
James Mcclary so true
I feel this man drives for swift and never has heard of the past I had a T680 with a paccar MX-13 only lasted for 400,000 miles but I still have my first truck I started trucking a 1999 FLD 120 with a 6NZ boy if I tell you is one of the most reliable truck is has 2,500,000 miles and has cost me 3/4 less then the T680 paccar will never be as good as Detroit Diesel or Cummins and Cat the reason cat stop making engines is because they couldn’t not meet today’s EPA requirements all the Bullshit that California wanted a fellow trucker of mines has a 2011 Peterbilt 386 remove the EGR DPF boi that Cat C13 change I made more power and the engine was a 2006 engine before that bs of DPF started that engine was made to run with out a DPF what you need to do is go and stop believing that the Paccar bs shit is going to be good it will never be as good as other Diesel engines in the market do your research why the ware defective blocks and once you do that STOP TALKING SHIT OF THE BIG 3 o hold up you want the Answer why Cat had defective blocks ooo I got you is cus they could keep up with the new emissions of the EPA
B M Like I said ppl like what they like. Paccar is nothing more than a Cross between a Cummins and a cat. More so the Cummins. Many of the Cummins paccar parts interchange.
I’m glad your truck has 2.5 million miles but most ppl don’t keep a truck that long.
Your right it will never be as good as any of the engines you love but that does not mean they will stop making them.....
I drive for one of the biggest and best trucking companies... My favorite truck right now is the Peterbilt 579, but my company has stopped using the 579 and the T680 because of electrical problems. So when I make my truck purchase I have to go with a reliable Freightliner that you see to many of on the road... But as I said I LOVE the 579, but it would not be the best choice for my truck purchase...

@@ItalianStallion1415 Then you must not have experience because simply lifting your foot off the brake and applying pressure to it again to stop as you back up is as easy as pie and response time to stop is also better. Moving your foot from the brake to the gas and back to brake is obviously not as easy, which is the reason "why" it's nice. In your experience. Amazing.
just my 2 cents....i got 2016 KWT680 paccar mx13 2013 GHG with 1,040,000 miles on it...never any issues on it....in my case really did B10 prediction
Man... the comment are not good for this engine. Sounds like it's $3500 cheaper on the front end but $15,000 more on the back end. The only way I would try this from the comments is if they covered the unit fully for the 5 years I'd own / lease it. No need to risk my hard earned money. I'd let them risk their's however.

Sounds like e everyone's complaints are from older paccar engines. What about the newer ones. And i love how people say cummins dont have reliability problems . Of course they do . Cummins problems are there loud as shit and are about as refined as a cement mixer and get sht gas mileage. Its time for cummins to put some technology back into there engines . Cast iron is antique technology. There are much stronger metals out there. But these companys use cast iron because its cheap to manufacture..
Some great points Robert. The Paccar engines came out at the same time as the emissions standards changed. You know....the standards that almost bankrupted International and put Cat totally out of the game. The fact that these engines ended up making it through that and work as well as they do......it's a great thing. Guys that don't like them are running 10 years behind the game.

I didn’t even know Paccar made engines until today, shows you what I know.
I really miss the Pre Emissions CAT motors. But alas those are gone for good. I haven’t given a paccar engine a try yet but I would like too. I’m running a T-800 with a Cummins ISX in it, can’t complain. As long as it’s not a POS Mercedes I’m happy for the most part. Every Mercedes truck I ever had was JUNK
It's a great engine. It's a derivative of the DAF engine that's been used in Europe for years. There are a ton of great features engineered into it for longevity.
@@KenworthofRichfield Sophisticated engine with more power per Liter (gallon) and less noise. See this video that's showing the MX-13 doing its job in the rural areas of Brazil.
How much horse power can be pumped up to on m13 for bull rack hauling. Fuel mileage means little in this field. Miss the T600 cab truck, although being 6,2 I do not think I would fit in it at 300 lbs now days vs 180 at 22 years old. Just seemed tight but that model made me a Kenworth guy. Loved that extreme sloped hood. Do not like green color at all.
This truck is running 510 HP and 1850 ft lbs of torque.
mx13 are great but there is almost no service on the road exepct dealer ... no major truckstop shop work on mx13 make it real hard to fix ... and dealership have wait list.. most of the time until they get as much service as a cummins or a detroit i don,t think people will shift toward it
Did they upgrade the emissions system? I here alot of drivers say the paccar engine is a great engine if you get all the emissions deleted
There is no PACCAR motor in my future.
sachmo omhcas then don’t buy one
how about a paccar engine then?
or collision migration system!
@@chakagillis Lol
Wise move
Having driven a paccar an isx and an mp8 mack motor. The paccar is hands down my favorite. Its smooth at any rpm, I do however have to disagree with the peak torque rpm. From personal experience it seems to love running the top half of the rpm range with shifting around 1500 vs the 1000 the auto trans wants to shift at. The ones I've ran have been 430-455hp and will walk away from a 500hp DD15. I'm honestly surprised that at 500hp the torque number is up there with the X15 despite being smaller.
I will say that if this engine didnt have the emissions junk on it that we are forced to have then they would be an excellent engine.
The 500 hp Paccar definitely has a lil more fuel going to it versus the 455. My first T880 W/ the Paccar 455 definitely had a little bit less going to it compared to my current 500 just by comparing the info on the engine data plates. I've had my Paccar as long side the DD 13, Volvo's 13L and Mack's as well and it pulled right along and in most cases passed on by them. I have a 18 spd manual behind mine and I run it down to 1000 rpms before having to drop down a gear. Heck, some hills I'll have to up shift cause the rpms will get over 1500 and I try to keep it within the peak torque and she pulls right along. We have trucks with the 455 and Allison 6 spds and I'll pull away from those trucks.
Our company runs MX13 for 1 reason , we lease all our equipment if it blows an engine who cares it's under warranty ... if we actually bought our equipment yeah it's for sure going to have a 550 x15 Cummins performance series
I’m driving a company truck peterbilt 2018 589 with mx13, put 350k on it no engine issues yet!!!
With that being said I’m looking into buying my own truck and dispite my great experience I would be worried to buy the same equipment if I had to pay the repair bills because of the horror stories I read about.
The biggest problem I have with the paccar engine is lack of dealer training etc .....
Every time I've ever had a problem with a check engine light / engine shut down I've had to continuously take the truck to the dealer due to the simple fact that outside repair shops don't have access to Davie or similar software.
9 times out of 10 this meant multiple return visits back to the dealer most of the time my driver or I would make it about 5 mi down the road before the engine shut down lite would return ...
Multiple problems with wiring harnesses for the emissions that I was stuck paying for until someone informed me that there was a service bulletin or recall after I spent thousands of chasing ghost repairs.
Then there was the EGR valve repair which normally I could have done myself except for the simple fact the quick connects for the coolant lines on the EGR never worked properly and dealership informed me that there's a retrofit kit and I'd be looking at about $4,000+ for a simple EGR valve ..... I bought used EGR valve and a brass compression fitting fix that...
Then there was a problem with horsepower multiple times I was told that the engines had a 500 horsepower rating let's just cut that in half and that's about the performance I received out of the mx-13 engine.
The green is a giant sos bill board alerting wrecker drivers to spot you easier when you are broke down
Sorry, no Collision system for me, nothing touches the brakes but me, because i'm not taking a chance on a false reading to wreck me & then i'm screwed! Because the DOT is not going to Cite the system, they will cite me!
I drove a brand new (less than 1,000 miles on it) 579 with the mx13 a year ago. It was a fleet spec so it was probably the lower power unit. What a turd that truck was. I'll stick with a c15 6nz and 13 speed manual. Night and day. I never struggle with the old 379. I run 76,000 to 79,500 most of the time with no issues. That mx13 579 was struggling at 50,000 plus. Under that and it got great fuel millage so there's that.
“Collision mitigation “ systems are prone to false alerts which teaches drivers to ignore them.
While that is possible, these systems are rapidly getting better and better and improving with each generation.
@@KenworthofRichfield Yep, pretty soon the driver won't be needed at all. This is already the case for mining dumper applications.
Paccar engines are my first choice no doubt. Spent many years driving Paccar vehicles in Europe ( DAF ) before coming to the States via Canada. I would recommend Paccar any time....
It's funny how I don't really notice how quiet they are and how great the torque curve is until I drive something else. Then I miss it.
When you say you drove all of it in europe ..that engine was good without the emissions...right now not only parts are 25% higher but they started to put plastic or composite that crack easier on the engine ..if you switch truck every 2 to 3 years chance are you won't see those failure so ...but passed that more stuff coming to break
@@andrianatruckin7014 true
I ran a 579 with a mx13. It made damn good fuel mileage but was a pain to get serviced on the road. Few places had filters and shit for it. If the KW mitigation system is anything like Pete (i would assume they are since they're both owned by paccar), then you'll NEVER get used to it slamming your brakes while you pass a road sign or drive under a bridge. That system almost gave me PTSD and made me scared to drive the truck anymore.
Can you disconnect it?
@@707SonomaComa Collision Mitigation Systems can always be disconnected
I work for the company with the brown trucks. My 2019 T680 has been back to the dealer 4 times for engine problems. My terminal has 30 new T680’s with the paccar engine and transmissions. All but 4 have been back to the dealer for engine problems. One of them is at Kenworth now for the 7th time. Don’t buy a paccar motor if you plan on driving the truck more than a few miles before bringing it in for an engine light on the dash. The collision mitigation systems are absolutely dangerous as well. The
T680 with a X15 Cummins and an Ultrashift or standard transmission would be a great truck.
Our company brought about 50 dafs with mx13. Besides dropping liners they were good engines
Maybe the driver is not the best
@@dutchman2506 I agree the states has shit drivers that cant even drive on freeways and there not even that heavy. Our mx13z were loaded upto 58t 128000lbs and with our steep grades and windy roads if you know nz roads . Some lasted upto 1 million kms
@@nztrucker1542 1m kms isnt the same as a million miles
@@bradcoddington1679 yeah we know. We have trucks done 2-3million kms an still look new
You and I both know and wouldn’t go 75k miles between oil changes! Be realistic
I have replaced mine cracked up the side they have replaced about 30 of them. Then year later had to replace the pan gasket.
Cummins over paccar.. there's a night and day different in performance. Cummins is way more reliable and can take a beating.. if you're over the road... but if you're not doing long huals just a local tri state driver your should be fine with routine maintenance
Looking at a 2020 T680 with MX 13 and a 13 speed manual transmission and 3.36 gear ratio. Where does Kenworth say that the sweet spot is?
Virgil, There's actually a ton that will go into that in terms of what you're carrying, what trerrain, etc. A 3.36 is usually a good, conservative gear ratio that's balanced between performance and mileage.
The 3.36 is a great ratio for the old cats and Cummins. On my old trucks, that would give me 1350 rpm at 65. The newer engines are designed to get their best mileage at much lower rpm, so a taller gear would likely be better.
The mechanics at kenworth and peterbilt told me 2 avoid paccar engines without hesitation 😮
I thought president Trump was doing away with mx 13 ?
Bad experience with 2014 t680 and 2017 t680
With paccar engine
Eaton 13 speed automatic
Shifting is very bad
Change few software's but its same shit
I like interior design but quality is not good
it makes rattle noises from hood roof and dash
Its not quite trust me come drive mine its also green!
SERVICE
bad bad bad bad
Auto transmissions are still junk, the only company thats got a decent one is volvo. I had more break downs because of the auto trans then the emissions surprisingly with my old kenworth piece of junk
I used to drive a 2015 t660 with the mx13 and a 10 speed eaton auto. same thing. no power shifts were stupid. i didnt like it.
This has a completely different auto than what you ran, it was the missing piece of the puzzle.
That meat and potatoes engine looks more like a bowl of spaghetti. What a mess.
Im running a 2017 t-680 with 300k miles on it ..... I'm on knock sensor number 4. I've got over 25k in the aftertreatment system. all I keep hearing from the dealership as that's not covered under the 500000 mile warranty. I keep having stupid electrical issues. My advice to everyone Freightliner gets better fuel mileage and has way more options out on the road for service. All you have to sacrifice is a little bit of interior amenities. Stay away from the mx-13 from experience
This truck is the worst girlfriend I've ever had she takes all my money and has almost put me out of business four times.
There's got to be something else that's being missed here that's causing those issues at that time. How much idle time do you have?
Is there a difference in the 680 and the 880? They look the same.
880 hood is a little more squared up the headlights are different. 880 only comes in daycab or midroof sleeper no condo.
From the firewall back they are identical
T880=T800
T680=T660
I am in business to make money, you can sell the PACCAR to the dummies that don't do any re search but I for one will not work to pay off a truck that in the end has the worst resale value in the industry. Get on Autotrader find 2 KW with comparable specs one Cummins and one PACCAR. Look at the price. Isually $15,000 to $20,000 difference. The PACCAR is done after about 300k miles, after that NOBODY wants it.
Older Paccar engines got a bad rap. Especially because they came out at the wrong time. You know....the time that almost put international out of business and the time that made Cat stop making truck engines. :D
There are reasons as to why we have both engines available. In the same sense, the Paccar has great longevity.
Weird, but the Paccar MX engines are known as reliable engines in EU. I suspect Paccar adapted the MX for the US market. In EU max hp 530 in the US 510 for example..it even sounds different
Cfi is down the road at kenworth and they only use Cummins engines.
Nice I really like that truck and color!
We still have it here. :D Interested? :D
Sorry but I’m forever a Cummins guy
We can offer the Cummins engine in this setup also. :D
Why "sorry"? You like what you like, there is no need to apologize.
It's less expensive but they won't stand behind it???? If it's so good, give it a warranty....!!!
They do! You can get the same warranties that you can get with Cummins.
I wouldn't, we got both Kenworths and Daf in our fleet, the DAF is where the mx13 came from, they been dropping liners, exspensive trouble
We haven't had that issue over here.
I own a paccar 485 hp. Its been very good motor. I hope my next track will have one.
...DIDN''t i just TELL you ...not to call it a ...motor...simpleton....
A motor is technically electric only
I think people still have that sour taste or the first generation paccar...
I debating talking about that Jesse. That engine came out at the worst time! When you think about it, that's the timing that put Cat out of the road going business and almost put International totally out of business.
What year did the second generation come out?
@@coreysmith2196
2016
@@cactusjack1806 Yes...yes I could.
I’ve owned a 2015 680 with a Cummins, I bought a new engine for it around 800k miles. The new ISX got put in and I was still in the shop constantly, so I ended up selling my truck because it was killing me. I’m thinking about buying a used one with a Paccar but scared to pull the trigger from all the bad rap I’ve heard over the years, the year I’m looking at is 2020 with MX13
OK where do I begin first off the Detroit 60 series has used composite oil pans and valve covers forever so that is nothing new at all. As far as that adaptive cruise system as some call it its a accident waiting to happen I know it almost happened to me. Going west down I-70 into Utah icy roads during a snowstorm a cardboard box blew in front of the truck was doing 30 mph it decided to lockup the brakes ALMOST jackknifed the truck 30 years experience otr prevented that from happening.
2.79 rears? What are you hauling paper towels and toilet paper the engine is still 12.9 liters isn't it? Its a flat lander truck pure and simple. I have a 2016 589 Peterbuilt with a MX 13 in it 13 speed 3.21rears and I'm glad you all decided to change the valving on the egr and turbo because your old way of doing it well its junk. Loves to do what I call backfire through the turbo and egr which by the way messes up the $6000.00 turbo if its not set right. And almost ALL of them do it driven about 4 MX-13s and everyone did it?
OK I will take it to the shop and get it fixed sure if you can afford a 2 week wait period to get it in sometimes its only a week you forgot to mention that. Oh yeah you also forgot to mention that if you want to have it turned up at the dealer lets say 450Hp to 500HP it cost about $5000.00 dollars that's just so the factory and send the download to the shop and program the ecm! Thank goodness there are plenty of places to get it done at a fraction of the price.
Everything I have said is a FACT but one thing I have not talked about is the oil changes every 75.000 miles no way would I ever do that I'm 79.000 lbs+ all the time and a lot of mountain driving I change it every 25.000 and every time its black as coal and like water.
Now I fixed all the above problems myself and have not one problem since 80.000lbs flat land 7.5mpg mountains averages about 4.5 to 5.2 does not burn a drop of oil and tons of low end torque at 550 HP and will pass emissions wonder how that happened?
Quite the list and the story there James. Glad to hear that you're running with decent fuel mileage.
@@KenworthofRichfield Yeah with a lot more HP and less shifting.
Ive driven a 450hp Mx13 some years ago and the jake was weak asf...oh yeah and it was an auto which is why i quit them lol!
It'll put you through the windshield now if you've got it on level 4 :D
Kenworth of Richfield ok so u must be referring to the new paccar motors after they fixed all the kinks? I believe it too bcuz the new x15 cummins jakes are pretty strong too! Mattafact ive driven a new paccar now that I remember and yes they are pretty strong so yeah u are right!
Sorry to be negatively but you CANNOT get me to adapt to the collision system. My truck has it now and this things brakes for shadows that's on the road. Its extremely dangerous and since you added fuel mileage, please tell the consumer that it adapts to the slower speeds of traffic in front of you. So if its slowing down and uor having to pass, your burning more fuel to speed up.
Jacob, I'm going to have to call the BS on the "shadows" part. It uses radar/lidar setups....neither of which see shadows. Now, I have heard that there has been a "ghost" braking incident. This is usually caused by a mis-adjusted radar/lidar setup. Check with your dealership and get that setup correctly and it should help you out quite a bit.
Can you just tell me who or where I can take it off. I do not like the system.
U cant hardly give away a used trk with a paccar...
Get a glider of that, and drop in a freshly built 8V91 Detroit silver, or go bold and drop a 12V91 Detroit Silver in it. You might get your man card back, and people will stop calling you Dorthy all the time.. 18 or 13 Man-ual required. Oh, and no day glow lime green. It should be illegal.
hawkdsl id love for someone to do that
1st comment I’ve seen on here that I actually like lmao. I agree with that one
Yep or a big o Cat>> 18 on the floor!! Pac Car sounds like a Kids Toy LOL
It is a nice engine for sure. I have driven the MX-13 in a KW AND a DAF XF (euro truck) and way WAY better than the um ...... Maxxforce engine Internationals....
Remember those? I'm trying to forget them.
Boy that's such a low bar thought Lol!!
A 2010 paccar motor is junk!! Had a 2013 kenworth but they put a 2010 paccar motor. Nothing but problem. Could not keep it out of the shop..
all kenworths have several paccar motors in them. Or did you by chance mean engine?
It sounds like "they" were stupid.
I am curious though...which motor are you talking about?
HOLY FUCKING SHIT LOOK AT THOSE WIRES ALL OVER THE PLACE
Why do you got to make a TV show out of it get to the damn point
It's what I do Mike. :D
Honestly I prefer paccar over the new fake Detroit's and fright shaker and I work on them all so far paccar and Cummins I say are the most reliable
So far, we've had great luck with both the Paccar and the Cummins Andres
I'm surprised you spoke do highly of such aseco d rate motor. They have caused so many operators so much trouble
We've found quite the opposite with the engines in these trucks.
My oil pan cracked 2 weeks ago at 96k the dealer told me they had some bad batches made and I was the luck winner! They took care of it warranty no issues. Still love my PACCAR
I’m on my 3rd oil pan at 520k. I’m told is due to being over torqued during oil changes
