Will Thin Motor Oil Cause Engine Damage? Let's Settle This!
Вставка
- Опубліковано 2 вер 2023
- Many modern cars require very thin (low viscosity) motor oil to operate more efficiently. Newer engines typically have tighter tolerances between engine parts. Let’s see if lower viscosity motor oil offers the same level of protection against engine wear. We’ll also see of the thinner oil experiences greater thermal breakdown and evaporation.

True. And he does NOT waste our time. Dang! Condensed hard valuable info.
Thanks!
This man is phenomenal great job
@@ProjectFarm If you do another motor oil viscosity vs wear comparison, please consider making an equal parts mixture of 5W-20 synthetic and 5W-30 synthetic oils. If the wear scar decreases from that of the 5W-20 oil, but is also greater than the wear scar of the 5W-30 oil, then this empirically verifies that the wear rate of 5W-30 is not a fluke and that the wear rate is definitely better. Thank you.

When I saw that Jimmy Buffett passed away, I had my phone play "Margaritaville" while I got ready. I was in the shower when I heard some idiot talking, poked out my head, and it was an ad--after a 3-minute video, which had an ad before it.
It was some young and fit guy telling me that I could answer a couple quick questions, learn my body type, and learn how to best lose weight.
I answered some questions and he claimed that he just had a quick video to solve all of my problems--and talked for perhaps 30 minute.
I got dressed, did 30 push-ups, and drove at least 20 minutes before the guy finally finished talking.

As an Alaskan, I'd love to see the -40 oil put into the wear tester to see how they perform when put to work in extreme cold. If nothing else it'd be a great video to show the importance of winterizing your vehicle (Transmission heat pad, Oil pan heat pad, Block heat plug to heat coolant, Trickle charger/battery blanket).
We tend to run thin oils here cause the winters are so cold. Fairbanks Area.
Thank you for the video idea!
im still waiting to see the power steering video. I live in the Montana mountains, and -30 isn't uncommon; then add on I have a leak, and I want to see how different power steering fluids handle
sadly I don't have the money or power outlets so I can winterize my truck in any helpful way bc I cant go out and start it up every day due to gas prices
Yikes I can imagine how cold it gets up In Alaska… I’m from the upper Midwest and luckily it still 95° here. 😅
An interesting thought, but I think it would make essentially no difference.
Ya it'll start out at -40, but the friction will heat it up FAST.
It's not like you wreck your engine with a cold/dry start one time, it's doing it hundreds, or thousands of times that gives you issues.
I guess you could swap the wear part to a softer metal and perform a shorter test, to try and compensate?
How do you survive up there? As a Canadian, I can get used to -30⁰C

ABSOLUTELY, THEY ARE HERE TO DISCREDIT REALITY
Sure seems like the oil manufacturer added more additives to the 0w-16 to try and offset the increased wear of such a thin oil. Thank you for another informative test.
Exactly!
That’s what Toyota uses and they are known for reliability and longevity
Unless the heavier rated oils stick to metal surfaces the heavier oil has a disadvantage when cold. With most wear taking place upon start-up the 0-16 has an advantage in this respect.
@@michaelbassett5105 Honda uses 0W16 on some models I think I heard as well.
Efficiency is good when you own it, longevity is better for the next owner
Friction reduction has seemingly lost to fuel efficiency when it comes to the purpose of oils. I still run "thick" oil in the summer and lighter oil in the winter, glad to know that lessons from Papa still hold up🤙
Thanks for sharing.
I lived in Ohio. I had an 85 Ford F250 with the 6.9 IDI diesel engine. Ran 20w50 in the summer and 10w40 in the winter. No blow by 👌🏻
That logic checks out, I would be concerned about sludge buildup if you aren't really getting the engine up to operating temp for a sustained period of time. All oils do it, synthetic or conventional but synthetic seems to degrade worse in subpar conditions from what I've seen. Be well and make sure to keep your oil changes often and frequent...oil is cheap-ish while engines and repair bills are anything but🤙
I don't think "friction" as he tests it here really is how the engine sees friction. One thing he hasn't tested is "pumpability" when cold or hot. Probably way exceeds his method of testing for friction.
I could be wrong but I believe he has created a "backyard" version of the actual tests conducted industry wide🤷
With that said, the ability to pump the goo around at various viscosity levels is planned out heavily by manufacturers...unless you have minus 50°c for a month and freeze your coolant all should be fine under your hood👍
6:25 yes! Thanks for letting people know this. Also the "S" that they have dropped off the end (10w30s) stood for Summer. Before multi viscosity oils folks would change viscosities for hot and cold seasons.
The best automotive channel for me, straight to the point, no click bait, no gimmick, no weird music 😎
Thanks!
I'm retired but worked for a company that developed the micro-finishing film that most engine manufacturers adapted. There was extreme focus on the micro-scratch surface left by the finishing materials and very distinct to the design of a particular engine. There was much more engineering and research on this aspect than one might assume. When the manufacturer recommends a specific oil type and viscosity range, they have some well researched reasons for their recommendations. Modern, low-friction piston ring design also factors into what the manufacturer tells us we should be using.
Thanks for the feedback.
You said what I came to say.
EPA probably is the most reason for the low vis oil and high mile oil change intervals.
@@DISOPtvexactly. Thinner oil gives better gas mileage. You’re trading off longevity for efficiency.
The engineers only job is to build an engine that is more efficient than previous generations. That’s all they care about. They only need it to outlast the warranty.

I run 20w 50 in my hotrod and in the high performance engine in my boat. Both are only used in summer months. I use 10w 30 in my other two Mustangs.
I tried 20W50 in an old '79 Plymouth Horizon I had. The engine needed a valve job and was burning oil. One day the temp dropped and the starter could barely turn the engine over.
@@gadgethunter5732 thats what happened when I had it in my old BMW during the winter

Slow your voice down 🙏 please
My last oil change on my 2016 Silverado, I mixed 0w-20 and 5w-30. The truck runs noticeable smoother. Next time it will be all 5w-30. Cold flow isn't a consideration as I live in the desert of Arizona.
If the car is older, you can use 10W40 in hot climate
I thought about doing the same on my JL wrangler... just to be safe....
After watching this video and forums....
My first oil change is coming up at 1500 and want to give it a head start on engine life by doing an early first change. And I live in Florida so it's rarely frigid here maybe a couple months of below 45* nights
@@wailingalenPersonally, my opinion on a new vehicle is to stay with the oil viscosity recommended by the manufacturer and what is says in the owner manual. Sometimes manufacturers will list more than 1 viscosity based on temps and usage, but usually it is just 1. If you use an oil that is not recommended and you end up with an engine problem under warranty, the dealer will void the warranty. And unfortunately today, manufacturers have more problems with new engines than you would think. Maybe you don't want to wait until the warranty is over, but it may be good to wait for a year or 2 and/or 15,000 miles or so... just to make sure. Also, if you can I would stay with the winter grade and only increase the grade for the hot weather viscosity. In other words, if it says 0W-20, think about 0W-30, or instead of 5W-20, go with 5W-30. You just don't want a high viscosity when you first start the car and before it is warmed up... I'm glad you are changing the oil at 1500 miles. Manufacturers say it is not necessary any longer, but I do that as well... Change the oil often and use a good filter; change fluids every 3 - 5 years or so; keep the air filter fresh; use fuel system cleaner (i like Chevron Techron); and drive it right... and it will last a very long time. I still drive a 22 year old Acura that runs like new with 238k miles on it..
Its important to remember that some newer cars have very thin oil galleries. Its not just about wear its about getting the oil through the galleries. If your oil is too thick and can't get through the galleries properly it doesn't matter how much wear protection it has cause your car will be getting very little oil on key components. .
@@mm-jx7gf you might want to be prudent with the fuel system cleaner, it's been shown to drop lubricity in your engine oil whilst it's in the system.
Awesome test as usual! I still believe the CAFE requirements have a lot to do with manufacturer selection. Obviously, I would want a "thinner oil" in a very cold climate during start-up.
However.... my 22-yr. old Buick calls for 10w-30 and I don't have any inclination to use anything else! Thanks for the tests!
I use 0w-40 even at -15°F, no problem whatsoever.
I use 15-40 in the summer and 5-30 in the winter, both full synthetic. 320,000 miles and not a tick from the lifters and it doesn’t burn a drop. Leaks a bit but not enough to get worked up about. I have to top it off maybe 1 or 2 times between changes and I do 10k plus changes. And top it off means IT’s just touching the low line and I like it at the maximum mark. More oil equals better cooling from it.
I have used conventional/semi-synthetic 10w-30 in every vehicle I've owned in the last 21 years and have never owned a vehicle that didn't last 400,000 miles or more. I have done this regardless of the manufacturers specification. All of these vehicles succumbed to rust or driver-induced failure...no engine failed because of my choice of oil. That said, I changed my oil religiously at 3k or 5k miles (3k for conventional and 5k for synthetic). I also DROVE my vehicles. I beat on them and/or I drove them for significant periods of time to evaporate the condensation in the oil.
Thanks and you are welcome! Thanks for sharing.
I used 5w30 in -30f and it worked fine. It started a little slow but I think that was more battery 0w30 felt about the same.
I agree it is all CAFE even 0w16 cars here recommend 0w20 to 10w30 in other countries. People try to say the engine was specifically engineered for oil that thin. If it was then the manufacturer wouldn't also recommend 10w30. Engine clearances have been the same for a long time. Tolerances have gotten smaller (less variation) and the finish is better but the actual clearances are about the same. Todd's new truck having half the oil pressure also supports this, same size holes thinner oil = lower pressure.
Companies care about profit and they lose money if they don't meet CAFE numbers. If thinner oil reduces total engine life but gets a better CAFE number of course they will do that.
Next year CAFE is 51 mpg cars, 36.6 mpg trucks and 45 mpg combined. For every 0.1mpg under those numbers they have to pay $5.5 per vehicle produced.
Miss the number by 1 mpg and you make 1.8 million cars (Toyota or Ford) thats $99 million dollars lost. Wonder why they are looking into 0w8 oil?
Longevity is not always or is never the primary goal.

In extreme cold the oil getting there quickly is far more important than anything else.
I think a different low temp test should be added to represent the situation most people are in during winter, such as zero degrees F.
@@bills6093Did you watch the video?
@@Dr-UA-cam Yes, his freezer is at -40F, a test which doesn't mean much to most of us.
But an engine block heater makes that a moot point as the oil won't be -40. Also it should still be coated from the last time it ran, unlike in the test where it gets cleaned between uses.
@@Dr-UA-camwhat hes saying is also test the cold oil from 0°F not just warm new and -40 because a majority of people arent going to see -40 temps where they live

I believe Project Farm is recognized unofficially at least as the goto for product test results because of his scientific method, testing multiple ways, and objectively stated results.

You are welcome!
Not just for efficiency, hybrids especially plug in require thinner oil. Imagine this, you’re stuck in traffic for a while and only using electric power. Once the traffic is clear and you put your foot down, the cold engine kicks in for power. But the thick oil doesn’t flow quite easily as the thin oil does when cold, you end up damaging the engine even more
@@Dankboi420 if you love in the cold sure everywhere south of the mason Dixon line here in the states is usually above 30 degrees after spring they never go below 80 in Texas until winter

Problem is the manufacturer doesn’t always have the customer in mind. They often engineer things to bring in more service otherwise their goal would be longevity but longevity doesn’t keep stealerships happy.
Thank you for sharing!
💯
You make an excellent point. I think manufacturers can be trusted as far as which viscosity to use but the oil change intervals is where they get you. My recommendation is to use the viscosity they call for but under no circumstance would I wait for an oil life monitor to tell me its time for a service.
If someone can’t easily figure out what engine oil their vehicle takes than they have no business doing their own oil change.
I agree. I’ll put more trust in the recommendation of the man who fixes the broken car than the recommendation of the one who designed it to break at a pre determined point.

Awesome! Thank you!
Thanks for doing these tests and it is nice to know that 5w-30 is a good oil to use and that's what GM calls for. Great stuff indeed!!
You are welcome!
Additives make a huge difference on wear. It would be interesting to also do a test with bearing material instead of, or in addition to, the test wheel & pin you are using. I'm pretty sure that is what oil companies tailor there additives to.
Thanks for the suggestion.
I'd also like to see it be done under pressure somehow, since this is how the engines runs.
These pins are often made from a standard ball bearing steel. 100Cr6 or 52100 I think is the yankee name. ;)
@@jackmclane1826 yes, but that’s not what rod and cam bearings are made of.
Valve lifters/tappets,cam lobes,piston rings/upper cylinder walls,also timing chain links/rollers. Ball pivots used under rocker arms and pushrod tips.
Some cam drive chains and sprockets may be larger/better than the minimum practice,also some modern engines use "roller lifters" to try to reduce demands on lubrication but then there is the axle that the roller rolls on !
The oils are constrained by the fact that the EPA does not like a lot of antiwear additive(s) because of the idea that if the engine is burning a bit more oil than desirable the additive might poison the catalytic converter. I believe EPA has even found a way to spread that to Diesel engine oil requirements. So that obsolete SG rated oil from a few years ago may have had better antiwear performance under adverse conditions than today's oils although such standards as "GF-6" or "GF-6A" are an attempt to come up with oil that will offer adequate protection even with the EPA not allowing much of traditional antiwear additive.
I believe the super long oil change distances being advertised by the car makers today are pushing the oil far beyond what is safe. I believe that the additives wear out. A broken in engine is easier to lubricate in my opinion than a brand new one.
ideally the connecting rod and crankshaft main bearings are "floated" in oil most of the time that the engine is running.
Another great video. I'm old school and always thought a thicker oil was the way to go but I'm changing my thoughts a bit on the matter. I was always a 15w 40 guy in everything even small engines. I've never had an engine fail using it but sometimes colder starts were a problem. Then the 5w 40 diesel oils came out and I slowly switched everything to that. Boy did it make a difference in everything especially the diesels. I've come to the opinion that unless the engine is under maximum load and at high temperature all the time the thicker oils may not be necessary. Also oil pressure is an indicator of resistance to flow. So low oil pressure doesn't necessarily mean the engine is not getting oil. Engineering is constantly trying to improve fuel economy and I think that is a major factor, but also I think modern engines using thinner oils have a much higher oil pump volume to try to keep things cool. It's hard for an older guy to get his head wrapped around a 1.5 4 cylinder stock engine producing 250+ hp. Most all auto engines have oil coolers today and that says something. More power in a small package turning higher rpms and a turbo or 2 make a lot of heat and thinner oils flowing faster pick up more heat and carry it away for cooling . Sorry long winded but I'm always trying to learn and understand
I think you will find most modern engines employ a coolant to oil heat exchanger, not just an oil cooler.
newer engines usually have a cylinder that's purposely designed to be micro porous, it means they actually hold onto thinner oils but struggle with thicker ones, couple this with reduced friction piston rings, tighter journals , oil passageways and bore sprayers designed specifically for thinner oils to flow through them it makes it a bad idea to put thicker oils in them. Even though the thicker oil itself is technically a better lubricator when put in a modern engine it actually lubricates worse and can potentially even cause issues.
Another thing to note is that a lot of new economy engines are direct injection which usually results in more carbon build up around the valves over time so using a thicker oil with less additives could increase the amount of carbon build up over time.
@@axeami1354 this all makes sense but then Toyota will specify 5w-20 in Europe and 0w-16 in the US for the same engine. If everything else were equal wouldn’t it make sense to equalize the oil specifications? Others reflexively scream CAFE but I’m not so sure
You grasped a lot of things most struggle with, a lighter oil doesn't necessarily mean less protection, because oil flow plays a lot into it.
@@tjm3900 exactly, it warms the oil in cooler weather. Also aids in bringing engine up to stable temperature. I was going to mention it but I figured I was a little long winded as it was

Hey Todd, have you thought about doing the bearing test AFTER freezing the oil? It would be interesting to see how each oil performs on a bearing when frozen.
I've wondered that. The thing is, once you actually get to the testing part, the oil has warmed up. You've got a good idea, but it might be difficult to test.
Thanks for the video idea.
5 gallon bucket and some dry ice could help keep the oil cold while set up takes place.
@@TheCAD66
That's a good idea!
@@TheCAD66
Just put the oil directly into the test cup and freeze it. Go from the freezer to the testing rig.
Always a good show, and thanks for all the time, effort, and personal money used to do these tests. G-d bless everyone.
Thanks!
This guy is a scientist, so good info, thanks for all the work.
You are welcome!
Great job, as usual !!! Always check out your channel for valuable info !!! Only run Pennzoil Ultra Platinum 0W-40 in my 2015 Volvo V60 T5 after watching your oil comparison and it runs like a champ !!! Thanks !!!
You're welcome!
Miss the oil test videos. I know you can only test so much so many different ways but glad to see another classic from you Project Farm. Love the oil test videos 😂❤
Thanks!
When we first got a carton of 0W-16 oil at my shop, I didn't think it was for a normal daily driven vehicle. I though it was some specialty performance oil for a 2 stroke or something. Just goes to show how much closer the tolerances are in these newer engines. I drive 20+ year old Japanese vehicles and run 10-W30 in them with no issues. It helps that it rarely gets below freezing here.
always hear that term "new tight tolerance engines". but in reality pretty much all tolerances have been the same since the 90s as far as japanese engines go. also the reason the idle oil pressure on his 2020 is so low at idle. same bearing tolerances but lower viscosity oil.
Thanks for sharing.
Always a great take away. Thanks PF 👍🏻👍🏻
You are welcome!
Love it ! Great job. I'd love to see a video on amsoil/ hotshot secret diesel oil and a couple of other common diesel oils
As shown on the bearing test the 5W-30 had the least amount of wear. Protect your engine.
The only reason the 5W-20,0w-20 and 0W-16 exist is due to the EPA push for higher mpg standards.
I had relatives working at auto factories that saw the EPA reports mandating it.
I was wondering about that. My 2014 Toyota Prado lists a range of oils to use given the max/min temperature, and you can basically use anything when in the range of 0-40 deg. c
I believe hybrid vehicles especially plug in hybrids require thinner oil. Since the engine is not always running, thinner oil flows better at lower temp
I have a question though. Does engine wear happen mostly when cold starting? And if it is so, what kind of tests would reflect the effects of viscosity on engine wear?
An idea comes to mind, start/stopping the wheel 100 times without pre-oiling them. Would that be more reflective of real world circumstances?
It only makes sense that a thinner oil will provide less protection from wear. I always used 10W30 (I'm 81 and pretty set in my ways), but I have never had car that called for these thin oils. My vehicle is a 1995 Jeep Grand Cherokee with the straight 6 cylinders. It has 240,000 miles on it and I have only used 10W30 in it, which is getting harder to find.
EPA doesnt give a damn about your engine, if you need to buy a new one is more money (and taxes) for the government
Always a great video, love the breakdowns and simplicity for anyone to understand. keep up the amazing work man, thank you for another great video
Appreciate it!
So Oil SAE ratings are based on outdoors temp. I a bit to the North, my outside temps dont get below -15F i use 5w-20 year round.
Also thanks to your videos i have seen the reduced ware on parts. Along with that stop oil leak one you did i went with the bardahl brand, less wear. my motor seems happy once more and no leaks! I also used your stuff for my Oil filter, Air filter and all kinda of stuff! love your work.
Thankyou for that well put demo, for a better informed decision,
You are welcome!
I hear some new Toyota calls for 0W-8 motor oil...seems crazy to me to use something so thin. Kinda sounds like they're sacrificing engine longevity for lower friction/better fuel economy
If it keeps going , soon it will be just 0...
Thanks for sharing.
Pretty soon Toyota will be calling for thin air instead of oil for lubrication. Gotta save themselves ¢ on CAFE fines
Very interesting! As an old timer it's hard for me to wrap my head around the idea that you should use the same 0w-20 motor oil whether you live on a permanent glacier where anything above freezing is considered a heatwave, or, like myself, you live in desert where you put on a sweater when temps drop below 80. I'm going to need more than just a manufacturer recommending that, because as an ex dealer tech I've seen manufacturers recommend some pretty stupid things over the years. Things that are designed to make them money, not extend the life of the vehicle. And before y'all start typing, remember that oil temp and coolant temps are NOT the same thing.
Id say in the end it comes down to the actual oil temp.
The higher they climb = the thinner the oil gets its as simple as that
If you open your owners manual it will have alternate oils than what's on the cap.
My 18 f150 says 5w30 on the cap, but in the manual 5w40 is still in the temperature range... (although 5w30 would be better for me in winter).
If you run a block heater 24/7 then your engine never cools down and your oil doesn't break down the viscosity
I can get 10,000 miles between oil changes if I use a block heater
@@thecloneguyz running a block heater 24/7 is absolutely insane.
You are wasting more money on electricity than changing your oil every month.
Thanks for the feedback.
Great tests, straight to the point. Thank You very much.
Thanks and you are welcome!
Awesome work as usual!
Thanks!
Great test. I never run a 20 weight in a turbo charged engine but that's where the manufacturers are going because of CAFE averages. I realize you have to tell people to follow the manufacturers recommendations because of the liability issue but they really don't care how long your engine lasts as long as it makes it past the warranty period. VW had a 7 year or 70 thousand mile warranty before they switched to 0W-20. Then they dropped the warranty to 4 years or 50 thousand miles. They wouldn't have done that unless they don’t have faith in the oil they're recommending.
Exactly what I was saying yesterday. Glad others are catching on the gimmick. Also don't trust the engine oil life indicator light. Just use full synthetic engine oil and change it at least twice a year even if you don't drive over the mileage limit.
Thanks! Thanks for the feedback.
VW has a 6/72K warranty for only 2018 and 2019 model years. They did it to help potential buyers feel good about the company again. Remember that they got caught cheating on their diesel emissions. They were fined and had to buy back cars from their customers (or provide other remedies). It had nothing to do with 0W20 motor oil.
If you look at the reason VW motors fail, it's not for lack of lubrication. Most times it's due to overheating. Their cooling system is overly complex and there are many places a coolant leak can occur. I've blown up two 2.0L VW motors in the past 4 years. Coolant leaks and runs low, then the motor overheats. Of course not temp gauge, so by the time the dummy light comes on, the motor is cooked!
Eurocars need a 30 or 40 weight period.
Their engines are not build for thinner oils.
@@alouisschafer7212 5W40 synthetic is recommended on most newer European cars, or at least it was.
It would be interesting to see a comparison between some of the newer "Hybrid Engine Oils" (Mobil1, Valvoline) compared against their "Regular" variants. Maybe add some tests with impurities/fuel dilution to see how they hold up? Always love your content!
Thanks! Thanks for the suggestion.
@@ProjectFarm Could you test silicone "oil" in place of crank case oil?
@aboy467 I'd like to see this as well.
A lot of important info in a short video. Perfect!
Thanks!
My understanding is that most of the wear occurs on a dry start up, before the oil arrives to the overhead valve train. That's why the friction tester wheel is coated with oil prior to testing. Wouldn't the much faster cold flow of the 0W-16 more than compensate for the decreased wet protection? Especially in vehicles driven short distances?
There's a large factor that never gets discussed, and that is thermal expansion. An engines machined clearances are tested and engineered to be correct --- at full temp. The bearing clearances are effectively incorrect at cooler temps, and accounts for much of start up wear.
I use it Lucas syn on all oil changes, 185300miles going strong, one bottle per change.
I think it would be a good video to test all 4 oils in your truck. Run 1000 to 3000 miles then do a oil sample test after each oil! Thanks for all your hard work!
You are welcome! Thanks for the suggestion.
caballeroloco............why don't you try it in your truck, anybody can get oil samples done.
I sent my Italian Iveco 6 cylinder Turbo charged diesel engine using Ams Oil 15-40W diesel with a by pass oil filter system that was like 2or3 microns. I sent my oil sample in at 15,000 miles it came back with a clean bill of health, I the tried the same oil at 25,000 miles and it was still OK? The trick was I changed the engine twin oil filters at about 7,500 miles and I kept the 3 or 4" diameter by about 12" inches Ams by pass oil filter till only one half of the filter was still hot and the other half much cooler? An engineer taught me that trick as that large oil filer was very expensive my engine went 350,000 miles when I parked it 20 years later as finding parts were very hard to get in the United States. I find it Odd the the same engine and Turbo charger was still good when I parked the truck?
Yes, because the test will show more results on where and tare. What components are worse. The 30w wate should be better for where. 16w whatever seems to thin depending on how hard you run your vehicle's.
@@77.88. I do the same on my Chevy cruze. It maybe where'd but it beats changing my oil like a idiot every 3,000 miles. I only do it once a year. It's the best feeling ever. Lots of pride saying so too. I run amsoil signature series 0w20
Just love your tests, sir!!!
Thanks so much!
Great test! Thank you and congratulations.
I love your videos there’s no beating around the bush always straight to the point. I rely on your testing before I buy anything. Thank you brother for the honesty 💪💪🇺🇸🇺🇸🇺🇸🇺🇸
Thanks and you are welcome!
Thanks for a great video! My 2002 5.3 Silverado has 358,000 miles, 5w-30 year round, non synthetic oil, and never had engine apart.
Wow. How often do you change the oil and are you in a cold climate?
You are welcome! Thanks for sharing.
@kanyeeastlolz Yes, Minnesota actually. All my vehicles.. every 3300 miles. So 10k miles, change it 3 times. Then, every 10k,
rotate tires and drain trans oil (trans pan drain plug 4 quarts come out). It is sooo cheap to do this. I'm 65, retired, my dad taught me this since high school. I have always used Castrol gtx non synthetic. Just my .02 sharing.
Other UA-camrs should take notes and learn from this man, this is how videos should be made. Just get to the point! I love it!
Thanks so much!
Always appreciate your tests and results. Thanks
Sounds like I'll just stick with the 0W-30 and enjoy the benefits of cold weather viscosity and better engine wear long term. Love these tests! Great work!
Thanks and you are welcome! Thanks for the feedback.
The question is, what is the HTHS value of your 0W30 oil? In Europe, there are 2 types - 1. with reduced HTHS = from 2.9 mPa.s. 2. with normal HTHS = > 3.5 mPa.s. 0W20 oil has HTHS = 2.6 - 2.9 mPa.s. It could happen that HTHS will be the same 2.9 mPa.s for 0W30 as 0W20... and the difference won't actually be what you think.
Better to stick with what the manufacturer recommends because the new engines being produced today are designed around the oil and what the engine requires so by making changes you can be damaging the engine and therefore shortening the engine life. With Turbo's and Direct Injection things have changed also tolerances are much tighter so that heavier oil can keep vital engine parts from getting the lubrication they need. A good example is the dreaded Ford 5.4 3 valve engine it had small channels for the oil to go through and people that skimped on oil changes would get sludge blocking the holes and then robbing the engine of lubrication. Newer engines are even tighter with tolerances so they went to thinner oils to make sure everything got proper lubrication. It is unwise to change to different viscosities. Maybe back in the 70's and 80's it was better to increase viscosity because tolerances were different, but not in todays engines.
@@JasPlun Only problem with that is that it's our corrupt government mandating the 0W20 for .ooo1 more mpg. I spilled 0W20 on my driveway going to 10W30 for summer use, it was a warm day and in the sun. I soaked up the pooled 0W20 and then put away my tools, ramps etc...by the time I was done, I was going to get hot soapy water for the rest of the oil, but it had evaporated. Go ahead and use 0W20 in the summer to adhere to our corrupt government. And his evaporative test is exactly what I am talking about, so I won't use 0W20 in the summer.
Not necessarily true. Many times 0W30 specs higher viscosity at operating temperature than many 5W30 oils.
Greatly appreciate putting the stick with the what the manufacturer recommends. The thicker oil maybe provide better wear protection, but will definitely cause more damage when used in the wrong application. Unfortunately people may not understand that the oil recommended by the manufacturer is based on bearing clearances and other tolerances.
Thanks!
I understand where your coming from. But in the real world, I have used thicker oil for hundreds of thousands of miles with no engine damage.
The manufacturers are very concerned about EPA fuel mileage mandates because they get fined if they are not reached. Lighter oils give higher mileage. Whether the engine lasts 200 or 300 thousand miles is not their concern.
@@Olds_Pwr you've put 5w-30 when it calls for 0w-16?
@@drewhh6821 No.
What I’ve always found interesting is how manufactures recommend different weight oils for identical vehicles with identical engines in different markets.
For example my SVT Focus is recommended 5w-20 in the USA but 5w-30 in Europe. My Mazda Skyactiv-G 2-5l NA is recommended 0w-20 in USA and Canada, and 0w-16 in Japan, which has almost identical climate swings to the continental USA, and interestingly, 5w-20 in Mexico, which presumably doesn’t even need Winter-certified oil, or thin starting weight for that matter.
Seemingly same oils in different markets can have totally different compositions, might be a factor?
@@Broeils wow, never actually thought about that but you’re probably right. Good chance the regulatory bodies in different countries have different standards.
@@emotionz3 there's also different emissions regulations in different areas, and oil choice can impact emissions testing, and they probably have to test with the recommended oil.
@@emotionz3 No, the oils sold have the same composition - if they are meeting the same standards. And since they are shipped World Wide - such and such Penzoil Platinum Full Synthetic - 5w-30 will have exactly the same spec's anywhere.
@@daves7775 Many manufacturers order their oils in local refineries. Unless they control every batch, you do not really know if the oil meets the original specs. Only few companies produce their oils 100% by themselves and ship it worldwide
I’d love to see you compare small engine oils, Briggs, Kohler etc.. I love all of the detail that goes into your comparison videos!

Cant wait for the next challenge.This man is great
Thanks!
This dude is on point with his reviews/analysis, always popping up on my feed I’m late to sub but you definitely deserve it bro 💪👍
Thanks! Thanks for watching and subscribing!
Great test. If you could pump the oil across the bearing in the wear test may be more accurate when testing different viscosity oils. I noticed the thicker oil did not flow very well in the temperature tests so I had to wonder will it make it to the bearing surface at the initial engine startup?
Absolutely love this channel.
Thanks!
I'm just glad you specified to stick to the recommended oil per car as my dad failed to do that in one of my first truck and ended up clogging up my oil pump and the pumps intake screen because the oil was to thick and started sludging up within a 3000 mile range
Thanks for sharing.
What were the grades?
The most important part of the video was at the end differ to the OEM recommendation on oil viscosity. Don’t just throw a 0w16 at your engine if it calls for a 10w40.
If you live in a hotter climate use the higher viscosity of oil recommended if it’s colder vice versa.
The only thing you should probably take into question is the oil change intervals especially with forced induction engines.
Thanks for the feedback.
Wow, so much information ..
thank you sir !
Thanks and you are welcome!
I love your videos so much. Thank you for the great presentation.
Thanks and you are welcome!
Dear Project Farm,
Thank you for the informative videos that have real world application.
If I may suggest the following:
1. Calculate the weight loss due to evaporation as a percentage of the total initial weight.
2. Weigh the pins before and after and calculate percentage lost due to wear.
I look forward to many new videos.
You are welcome! Thanks for the constructive feedback.
Just for consideration, that late model Chevrolet showed in your video does not use an actual oil pressure gauge, but a “dummy” gauge which is programmed to stay at an approximate position as long as the pressure sensor sees X_psi minimum.
Yes, they are just an on & off switch mounted to the engine. The dash is an estimate based off of RPM.
@@duramax74 heck my Colorado does not have an oil pressure gauge at all, well it has one in the trip computer on the cluster but not a needle like my 1995 S-10 did.
