Agree on everything. I'm the slowest going up hill, even with light load. Keeping speed at 60mph, even speed limit 70. My ifta average never was less than 7.5mpg. 06 volvo, cummins 450hp, 10speed, 3.58 rears. My buddy drives same truck, but always speeding, he is averaging 6-6.5 mpg. Thats about $7000 per year wasted on fuel.
I drive a 2014 Kenworth T680 Phx to Albq and back to Phx. Haul light mostly and deadhead back to Phx mostly or with very little weight. ISX 15 2013 485hp 13spd 3.36. Best ive done from Albq to Phx with couple thousand pounds in the trailer I did 10.3mpg. 10.3 because the rush hour killed it. On I40 I had it up at 11mpg until Flagstaff. Hauling Phx-Albq-Las Cruces-Phx with a 28' my round trip was 9.1. 1,039 mile run with 114 gallons burned on the whole trip. At 1,000 miles I used 110 gallons. At 100 gallons I was 889 miles into my trip. Ever since I bought the Bully Dog Watchdog Ive seen better driving habits and I learn what the engine likes for efficiency. Like you said, keeping boost low, lower temps help a lot. I set boost limits. I run down hills fast if safe to use the gravity for the next hill climb. Phx to Albq I was 8.4mpg and used right at 50 gallons. Ive done the run for 6 years and drove it every way possible. Set land speed records when I was rushed. Now im the only driver and sometimes overwhelmed and hate that rush because it beats my truck up. I love the speed thrill but been having more fun trying to beat records for best mpg. Be safe no load is worth your life or others.
Boisja1 hey bro I'm from Alamogordo NM just got my own truck is you're company looking for another driver for the route you're talking about, appreciate you're reply!
Hey man, I am wondering how is that possible that you have 600 hp 2050 torque on engine that's been designed for 400 horse 1650 torque. I might be wrong but I believe for that amount of power you have to have a different CPL designed for the engine (injectors, turbo, you might blow off your Piston valves even your engine head, etc. etc.). But anyways I'm really impressed of MPG you are showing.
There are 2 versions of the isx. The lower rating version goes up to 450hp but the higher rating version goes up to 600/2050. It is indeed a different CPL so different turbo, compression ratio, etc.
Loves sells that bio-blend fuel that absolutely hurts MPG sometimes as much as 5-10% compared to straight “B0” ULSD. Also you’ll notice MPG goes to shit any time you fuel in states like OR or MN where they require by law that B5-B20 blends are sold, depending on what time of year it is. You’ll read a bunch of horseshit propaganda about how biodiesel blends only lower MPG by 1 or 2% but in real world experience I can tell you it is way worse than that.
I'm 100% agree with the driving style, some guys treat their trucks as racing cars...why??? I use to drive pretty much same way than you and the truck it's not even mine so.. Why some O/O do that crap to themselves??
The isx is a high torque low rpm engine. Pregressive shifting works especially well with modern high torque engines but if your routes do not require many shifts like if you are traveling the mid-atlantic then you would not notice the effect of progressive shufting. Doing 1500 rpm shifts with 20 to 30 complete stops in 10 miles thru the Bronxs is fuel foolish.
3.73 gears 10speed running 65mph means higher rpms. anything over 1500rpms, is bad for mpg. keep it 1300-1500. considering your egr is well maintained.
You do realize that the X3 version of the isx you are running is much worse on fuel economy than the X1 version right? Yours is designed for performance and response while the X1 is a fuel economy engine with lower ratings.
you are 100% wrong buddy , I tune, repair and build ISX series engines on daily basis . CM570 is dinosaur compare to cm871 and cm871 is one of the best and toughest ISX engines made so far . I can name few reasons , 3400 more adjustable parameters, higher compression, stronger 1 piece forged piston, stronger rods , liners are made out of tougher material , block has much better quality of cast steel. That's only few reasons why newer style of ISX series is much more tougher and fuel efficient engine.
+fxmdbosko I think you misunderstood what I said. I am not comparing different generations of isx engines...I am talking about the different CPLs from the same year. For example, the in 2010 and 2013 when the new engines were released, they always released 2 different CPLs (X1 and X3) which have different hardware and ratings. The turbo, compression ratio, cam profile, and tuning are completely different between the two. X1 is fuel economy, X3 performance.
+bkhaja89 actually there is no difference, I cross match every single part # and they all match no matter that cpl it is . Only difference is tune that's in the ECM that's it. I made over 800hp and 2300lbtq on engine that was 400hp factory and it's still running at 650whp map .
Once again, I am referring to the CM2350 engines and newer. Clearly you don't know the Cummins products like you say you do. Try looking up the part numbers for VGTs and pistons. Heck the X1 and X3 engines don't even have the same compression ratio. But what do I know...I only work there.
+bkhaja89 cm2350 is made from late 2013 to early 2015 , difference you are talking about is in the fuel pump , and injectors . they updated parts because they were known to fail . For your info no manufacturer in history made different ratio pistons and cams for mass production engine of same series. Looking from business point of view that would be most insane move ever , at the end of the day what you talking about are updated parts with new cpl's , only major difference is turbo size , some had bigger turbos for engines that produced 525hp and more .
Must not be pulling very heavy loads shifting at 10psi of boost . If I shifted at 10psi if have to drop back down a gear . And I'm running a isx cummins 550
drive looking at those gauges.. keep down shifting. cause an accident , slow down a traffic cause extra frustration for people behind you to change Lane. who are not as interested as you just to save some money on fuel. I tried all this saved me eighty dollars from PA to ca round trip and drove extra eight hours. don't believe me try it yourself. And you took all these tips from rawze's videos. bro safety is more important than money.
I love the video
Thanks for posting this. I'm OCD with fuel milage. It's good to see someone else crawl around slowly saving money!! 👍👍👍
Thanks so much for sharing friend. I'm taking notes.
thank you. great tricks

Love's is probably running a higher blend of biodiesel then the FlyingJ.
Hi ... What is you're rear axle ratio ???
Than you for posting this videos and all the advise.
AL
C15 CAT 7.2 mpg average over four years.... you better believe it. Driving habits, minimal idle (Worm up and cool down only) ,APU, maintenance.
I love how old school u are lol
I have same BS with Loves diesel
I have a isx 400 10 speed 3-35rears is there a way to ecm upgrade what do u recommend
What software do you use to adjust your ECM
What you are describing IS progressive shifting, isn't it? What am I missing
Wow I've noticed the same issue with loves diesel the mpg on my truck decreases like crazy its noticeable poor

I normally carry 150.ooo to 200000 pounds. from 110 to 190 .feet long. normally 20 foot tall and as wide. can u teach me some new tricks?
Bro you wont beat me on a hill , trust me..
When making money becomes a race with bonus payoff at the end I will most definitely have enough to compete.
Loves gives you less gallons for the the money. I fueled 198 gallons on my 200 gallon capacity tanks and I had fuel in my tanks. Explain that
I'm 100% agree with the driving style, some guys treat their trucks as racing cars...why??? I use to drive pretty much same way than you and the truck it's not even mine so.. Why some O/O do that crap to themselves??
Sometimes time is worth more than fuel
The isx is a high torque low rpm engine. Pregressive shifting works especially well with modern high torque engines but if your routes do not require many shifts like if you are traveling the mid-atlantic then you would not notice the effect of progressive shufting. Doing 1500 rpm shifts with 20 to 30 complete stops in 10 miles thru the Bronxs is fuel foolish.
the spped is about company drivers don't care about the longevity of the truck, why should they? so they push it to the limit.
Have you ever killed anyone?
you are everything that took the fun out of trucking
You have 600 horsepower, that makes all the difference from 450 carrying 45k. 600+ will always be better on everything.
I have volvo day cab 2007 isx 450 1800t 3:73 and 10speed tr. bad on fuel 5.5mpg so far. Im going broke. I need help where should i start?
3.73 gears 10speed running 65mph means higher rpms. anything over 1500rpms, is bad for mpg. keep it 1300-1500. considering your egr is well maintained.
Anyone know what ever happened to this guy?? He won the lottery and stopped trucking??
13spd 3:58 ratio 22.5 tires
I am looking at a 2006 Volvo 780.. what's your advice you can give me??
You do realize that the X3 version of the isx you are running is much worse on fuel economy than the X1 version right? Yours is designed for performance and response while the X1 is a fuel economy engine with lower ratings.

Must not be pulling very heavy loads shifting at 10psi of boost . If I shifted at 10psi if have to drop back down a gear . And I'm running a isx cummins 550
77.000lb average gross weight.
Yeah just light loads . I'm pulling 140,000lbs
Shit , that's some heavy crap :). Anything over 5.5 is great for that weight .
drive looking at those gauges.. keep down shifting. cause an accident , slow down a traffic cause extra frustration for people behind you to change Lane. who are not as interested as you just to save some money on fuel.
