you validated what a lot of us shade tree engineers figured out why the early N20 BMW engines were having problems with failures. BMW dealers were reccomending stupid 15,000 mile oil changes to avoid giving free oil changes during the first 3 years. 100% if you like your car you send samples to blackstone labs and find out what your vehiclewants for oil changes. Changing a good synthetic at 7500 or less miles stopped a lot of people in the N20 engines from having problems. Moral of the story, The manufacturer and dealer dont know crap about servicing your car, get actual lab results to tell you what you need to do for oil change intervals.

[@losertown2785]

As an n20 owner and bmw tech I can agree the extended oil change interval mixed with poor timing chain guide material caused majority of the issues. BMW themselves recommended that interval and all the dealers had to abide by it for warranty maintenance but ask any tech who was around when that came out and they’ll tell you what a bad idea it was. Still today the most frequent Intervall I see is 5k on some m cars, other than that it’s all between 8-13. Oils cheaper than engines…

[@Shadows-RC]

What about a N/A Mazda based direct injected 2.0 duratec Ford engine in a Ford EcoSport? Ford manual Recommends 5W-20 and an option for 0W-20 in winter. The problem is that this engine dilutes the oil with fuel quite badly. I have nowhere far to go and limited money so I can't just drive far away all the time to evaporate the fuel out of it. I simply don't have the money to go that far. So, I have to short trip. I can't afford a better oil than maybe a $26 five quart jug of Mobil 1's EP oil. I definitely CAN afford a couple of Super Tech 'synthetic' changes every year. Was thinking ST's 10W-30 in warm months, and their 5W-20 in MI winter. Both of those oils have LESS polymer viscosity improvers. More base oil. The closer the winter number is to the summer number, the more the stable base oil there is in it. I realize 10W-30 is pushing the limits of the VVT, but would very much like to try it. I don't care about the fuel mileage. It already gets bad mileage for a tiny Fiesta based SUV anyway.

The last time I used Mobil-1 was about a year ago because at that time I noticed that it looked really thin and dirty after about 5000 miles and I thought maybe the formula had changed because it just looked like it was all broken down.

Good information for the unknowing. Wide range oils with heavy modifiers do shear. But most people don't know what an HT/HS spec is and don't look for it. Some manufacturers are now omitting it (hiding it?) from the PDS and stating "we met the xxx.xx spec", which tells us little of where they were in that spec's range. They cleared a bar - that's all we know. What would be _very_ useful is these same shear tests run on a dozen popular oils in each of the 0W-40, 5W-30, and 5W-40 stated ranges. Perhaps with their HT/HS specs to provide some correlation. That would get us around the information shortcomings from the manufacturers.

That Mobil 1 FS 0W-40 has the BMW LL-01 certification, so you are good to go. The updated version of FS 0W-40 is SP, SN, and SN Plus certified. I think it has much less calcium and has additives to address low-speed pre-ignition issues of small displacement direct injected turbo engines. I'm running the updated formula in my Infiniti Q60 (VR30 twin turbo engine), and even though it is the Euro spec oil, it also has Nissan Performance certification as well. The updated FS 0W-40 is slightly thicker with a kinematic viscosity at 100* C of 13.8 for what it's worth. The old blend was at 12.6, which is barely high enough to be considered a 40 weight. Your older BMW will have no problems with the old or new formula. I like it because of the high detergent load, which keeps things very clean.

My daily driver has issues with oil shear. The engine is a 1989 Subaru EA71S engine. That's a factory built racing engine for the FJ1600 open wheel race cars in Japan. It has 12:1 compression, solid flat tappet cam, low tension rings, and the camshaft is gear driven. The power band is from 3500 to 6500 RPM and power only starts dropping off at 7500. The car has 4.25 gears and 13 inch wheels. I rebuilt it around 200,000 miles ago. This engine spec'd a discontinued 10W-50 oil. It will shear nearly any 5w-50, 15w-50, or 20w-50 oil within 5000 miles or less, presumably due to the helical timing gears. Cruising RPMs on the highway are between 3500 and 5000 RPM, and it gets driven 500-1500 miles per week. This is essentially a racing engine that gets driven on the street, in traffic, every day. The absolute best oil I have found is HPL 10W-50. It can go 7500 miles in the summer or 10,000 miles in the winter and still be in grade at the end of that interval. The next best is Renewable Lubricants 20W-50 racing oil. It can go around 5,000-6,000 miles. Some of the oils like Mobil 1 5W-50 will be done in 1500 miles or 1 week of driving. I can tell when the oil has sheared even without an oil analysis as the hot oil pressure will drop lower and lower. When it's under 10 psi hot idle, I change it. HPL oil is absolutely worth it's weight in gold. My friend also runs the 20W-50 diesel oil in a 1982 Oldsmobile Toronado diesel which is also a difficult engine with regards to oil life and it lasts longer than anything else in his engine as well.

I even managed to keep a 2006 Ford Fusion alive without any engine or transmission problems to well over 200k miles until a guy decided he no longer wanted me to drive it and slammed into the back of me. Never leaked or burned a drop. That’s a fact. Other than the valve cover gasket I changed a few times but that doesn’t count as a leak imo is the only oil to ever escape that engine. My civic even as a teenager was to notch even when I was beating the hell out of it gained the comment from the guy who did the head gasket “what kind of oil do you run in this thing” “ it’s the cleanest engine I’ve ever torn down at 225k”. Simple… Mobil 1 fully synthetic and change that shit every 3500 miles.

Mazda RX-8 is a good example.

The result was that you'd rarely see an engine that lasted longer than 60,000 miles that hadn't worn it's bearings away and thrown a rotor tip seal around it's casing when they collapsed.

My father used to do this kind of work decades ago, mostly on military lubricants. Some of the stories I heard (those not wrapped up in military secrets...) were illuminating. He would swear by Castrol GTX over competitors back in the '70s and '80s - it wasn't all advertising hyperbole (though this was back in the days when synthetic oils were just a geek pipedream and normal people put up with old-fashioned mineral oils, so overall standards weren't so high). The one thing that has never changed is that lubricant manufacturers and car makers have different ideas about how often oil should be changed. Take whatever the car maker says and double that frequency (at minimum), is a good rule of thumb. The military lubricant horror stories mostly concerned cost-cutting, the arrogance of officers who thought they were in charge (because technically they were in charge of the pieces of metal that used the lubricants), plus high-level Civil Service decision-making where technical evaluation results would be disregarded because a decision had already been made. For instance, sample bottles of a pretty glittery black liquid that had come out of Tornado fighter jet engines: my father's lab had recommended against using a particular additive in particular circumstances and what did he find in this pretty glittery sample, but decomposition products of this particular additive. No no no, we were told to use this, said the Air Force... except that it was meant for tank engines, not jet engines and somebody high up in the Ministry had rubberstamped sharing a particular lubricant between the Army and the Air Force in order to get a better price. Oops. This was decades ago - probably safe to mention now because we can be confident that the Armed Forces never ever cut corners nowadays....

Amsoil was the world's first synthetic oil to receive a certification from the API in 1972 and Mobil 1 was released in 1974. Back in the 70's and early 80's after trying several mineral oils, I determined that Castrol 10W-40 was the king and I became a faithful consumer for a number of years. Then I began to experiment with different brands of full synthetics, until I found a 100% synthetic (Amsoil) that I assessed it to be superior to the full synthetics and I have used exclusively Amsoil for the past 20 years.

Never really cared about viscosity until we bought a GM 3.6 and the cam sensor played havoc on our check engine light. Started using Royal Purple, saw no change. Moved to Amsoil. No improvement. Only driven 3500 miles p/y. I change the oil every 9 months, screening the used oil for particles. Only when I began to drive for 300 miles or more would the check engine light go out. The engine runs strong. So I'm back to using what's on sale. Going to learn those additives to make better selection. Video is great, because it makes old brain have to work.

If my house needs a new roof, I'm not just going to put the cheapest material I can find on it, installed by someone that doesn't have a reputation or body of work that expresses quality. Same thing when we choose an oil for our vehicle, do your research and buy a trusted brand (or just have the dealer do it if you cannot be bothered.) Then do your maintenance often to protect your investment (AKA, don't always just do what the MFG recommends at a minimum.)

And once you see that, will it make you an oil engineer? Probably not.

[@LTVoyager]

Given that most of us likely have no idea how the quantity of wear materials in an oil analysis correlates to engine life, a video on that would be very useful. For example, if iron is 50 ppm at every 5,000 mile oil change vs. 10 ppm, what difference does that really make? Personally, I suspect that even if every oil sample had 50 ppm of iron, the engine would still last 200,000 miles and with 10 ppm it might last a million miles. Given that few cars ever see 200,000 miles, are we talking about differences that don’t make a difference? Inquiring minds want to know.

[@ALMX5DP]

Yeah I'm interested as well, though we have to keep in mind that engines can fail in a variety of different ways and some fail over many thousands of miles while others can fail more suddenly. For engines which last on the lower end of the spectrum, irreversible symptoms may develop well before that and influence decision making on keeping the vehicle overall. I'd still like to know what differences in OA values truly mean but will always try to be the most considerate I can be to ensure my engine is at least above average in terms of potential lifespan.

[@LTVoyager]

@@ALMX5DP My point is simply that many things we do are in the “lipstick on a pig” category. I live in northern PA where we use copious amounts of road salt in the winter and rarely will a 15 year old car pass inspection due to unibody rust. Even body on frame vehicles like pickups seldom make it to 20 years. Given the 12,000 mile per year driving average, this yields 180,000 miles tops for a car and maybe 240,000 for a pickup. My last pickup was 20 years old when I had to get rid of it and it had only 160,000 miles. If 10,000 mile oil changes will get an engine to 200,000 miles reliably, then if you live in PA or NY or several other states, spending more money to change oil every 3,000 or 5,000 miles is a fools errand. It just means you junk your rusty old car with an engine slightly less worn than otherwise. Economically, it is insanity.

Take a look at the cP ranges for each grade over temperature and consider how it can be used in all different climates with similar reliability. Not that I have a problem with 0W-40 either, but I'd prefer more viscosity predictability/certainty. If you don't live somewhere that gets below -20c very often then I'd be using 5W-30. It's God's motor oil grade, because it usually takes very little VI's to make.

[@duroxkilo]

@@kleetus92 i/m not sure i understand how an engine consumes a certain brand of oil but not another... all oils evaporate when heated up but the difference between brands is rather insignificant. some engines do consume oil from factory, i don't know what exactly happens when an oil brand apparently 'fixes' that... to 'shred' oil substantial pressure is required. i don't think chains and tensioners present that sort of stress, that's not where the torque/pressure is applied. (as it was shown in the video, the testing device applies about half a tone of pressure in order to shred the polymers) if that were the case, the transmission of a motorcycle (most imports use the same oil for the gearbox and clutch) would 'destroy' oils. but that's not really the case according to oil analysis. even older generation oils (most bike oils are API SM) maintain viscosity to satisfactory levels. my v-twins measure basically factory compression and mpg after a few trips around the globe worth of miles. the oci were extended based on the analysis of used oil. so that extra heat and lots of 'shredding gears' are still not able to degrade oils that aren't used in cars for more than a decade now... the engine wear is minimal to non-existent. anyways i responded because you mentioned anxiety and my point is ppl tend to stress about oils for no reason. test the oil, test the engine compression, watch the mpg (signs of engine wear) and it's fairly easy to realize stressing over oils is mostly unwarranted. racers have a different approach because those engines operate at their limits and sometimes beyond on a regular basis. for those applications engine components are consumables w/ a rather short lifespan. a daily driver engine has a very cozy life hence their longevity these days...

You missed the most important test comparison! Test 20w-50 Vs 10w-60 and 5w-50, etc. You should have explained that HTHS depends a lot more on the BASE oil before VI are added. You did hint at it this at the end talking about your Porsche Boxster engine, but the point that needs to be made is oils that try to cover a very broad range (like 5w-50 or 10w-60), do so with large amounts of VI which can shear down and lose viscosity. For enthusiasts who never drive in cold weather and do not need low cold temp cranking at -30C, having a base oil that meets 5w or 10W is simply not needed. It is better to use a motor oil made from a base oil of 15w or 20W and achieve the higher temp viscosities with LESS VI improvers.

This is why I always add Lucas Oil Stabiliser to my engine oil - to maintain viscosity

[@peskypeet]

Hey Lake, judging by the responces there seems to be a lot of interest in the Euro 0w40 & 5w40 formulations. Perhaps you could do a comparison of those from Mobile 1, Castrol, Pennzoil, Valvoline. Then discuss the 30w alternates.

It amazes me how many people wanna stretch out their Oil Service interval. A tank of Fuel costs more than a bottle of oil! What are you doing? Hell, most of us could afford to change oil and filter monthly if we didn't buy Barista Coffee!

Some of us already change our oil and filter monthly--WITH the extended 10k mile schedule. On the conventional schedule, this would become a weekly chore costing almost two extra tanks' of gas worth in money.

@notsonsered103- The video isn't really covering drain intervals. If an oil is formulated for safe extended drain intervals, then there's no benefit in changing it, other than donating your money to a mega-rich oil company. -- 31 year independent AMSOIL synthetic lubricants Dealer.

It amazes me how stupid people get thinking about oil changes, when in reality average Joe in USA will sell the car long before any issues will arise. All tis oil talk is worth nothing in USA. Now if it was India or some other shithole country where people shit on streets in broad daylight and drive 35 year old cars - then i would say oil change is important topic for them But even then it's as simple as to change oil once a year and call it a day.

I do like your approach to have data speak for itself. It would be great to see a comparison of brands of modern narrower viscosity ranges, i.e., only 0W-20 like Mobil1, Amzoil, or others offer to see how they hold up to the tests that were done in this video.

[@craigmccolm285]

Really like to see how Amzoil compares

[@hugh007]

What I got from these tests is the narrower the viscosity range, the less likely to have shear breakdown. 10W30 vs. 10W40, 5W-30, etc.

[@Jeff_Seely]

Wow! I have used Mobile1 Full Synthetic for my oil changes more than any other brand and now I know I was correct to ignore these 20,000-mile guarantees! Thank you for this and I hope we can see some oils go head-to-head for viscosity tests. That would really be a treat!

[@ncsteeltoe]

I'd like to see a comparison of car oils vs motorcycle oils (Not harley oil, sportbikes with shared transmission sump.) The shared sump means the oil is subject to the transmission gears as well as the wet clutch in an engine that spins 16,000 rpm. That's some shear forces!

[@Tonyx.yt.]

the most important difference, since motorcycles had clutch plates soaked in engine oil, motorcycle engine oil didnt use anti frictions additives because would pair well with the purpose of clutch aka friction... that's also the reason why honda use different engine oil for motorcycle and scooters, both same oil grade 10w30 but different formulation because scooters like cars didnt had wet clutch

[@treborg777]

IMHO, turbochargers are the biggest threat to oil viscosity. I do oil analyses, and I see serious viscosity breakdown on my Mobil 1 0W-40 in an Audi Q5 (2.0 liter turborcharged engine) after 5K miles. I change my oil every 5K miles for that reason in that vehicle. In my Toyota Prius, I can run Mobil 1 0W-20 for 10K miles while still having good viscosity and additive package.

Turbochargers are more trouble than they are worth for most passenger cars.

Easily your best video TD LSJR! I use the HPL Euro 5W40 because of the Star polymer shear stability in mu tuned turbo VW that I track where I see sustained oil temps in the 270+ range giving me max protection. All of the previous xW40 oils sheared down to 30s almost immediately and the HPL seems to be the best at staying closer to grade based on numerous UOAs.

[@jimn.9990]

Wow, oil temperature of 270 F? You may want to try Amsoil 100% Synthetic 5W-40 or 0W-40 European Formula (PAOs with some Esters with a Lubrizol package). Many Amsoil customers claim a drop in oil temperature while using Amsoil.

[@karstgeo7290]

@jimn.9990 ​270 on track is quite normal for many engines. The HPL oil I use is a superior PAO/ester/AN product. There is no reason one 40 grade will run at a lower temp than another all variables being equal and I've collected much data on this.
