Could you review Schaeffer Supreme 9000 engine oil. Back when I was working as a diesel mechanic the place I worked ran Schaeffer in all the diesel engines. When I would perform an engine overhaul the rod and main bearings showed almost no wear at all. Other than minor debris "scratch" on the bearings they looked almost new. These engines I'm talking about were operated under heavy duty use. I've overhauled quite a few engines in my life as a mechanic from small diesel engines, DT466, up to large natural gas engines, 7042GSI, and have never seen bearings with so little wear than at my first mechanic job with those running Schaeffer oil.

[@LauraleyB]

Mr Lake, thank you so very much for taking the time to be so in depth!! I’m sure most of us don’t care how long your videos or live stream run because of how in-depth you go !! You don’t need to be “more smooth and polished”!! One of the things that I truly enjoy about watching your videos is that you are more down to earth and relaxed.. Don’t change who you are to be more smooth and polished. We all know how intelligent you are if we didn’t we wouldn’t be here!! we all have high level of respect for you. I’m sure that I’m not the only one that would be slightly turned off if you started being more uptight or up snooty to be more smooth and polished. I would rather watch you all day long as yourself then to have you be prim and properto make the Internet happy. So please don’t change who you are! As a female who’s been turning wrenches my entire life, my dad told me if I wanted to ride or drive. I had to learn at least the basics, and he started me turning wrenches on my first minibike when I was very, very young less than 10 he literally would stand behind me and walk me through how to do the basics, and he did that on my regular dirt bikes and then on my first car and if I wanted to use his truck and horse trailer to take my horses somewhere, ir to take the boat out fishing, I had to service his truck as well. So it is something that I very much enjoy. Watching you explain more in-depth is absolutely incredible, you are a huge wealth of knowledge and we are all benefiting from that!!! Again, thank you very very much!

[@themotoroilgeek]

Thank you! I really appreciate that feedback. I’ll keep things as are.

I'm almost 60 years old and grew up with 3K mile oil changes and in my case bought into oil additives all these years actually up to the point of watching your videos. I no longer will purchase anything other then the oil which I've used synthetic for many years and I still change oil 3K-4K miles but now I'm more in tune to getting my oil tested and picking the right one i.e. A student. Thank you for getting me out of the 80s and having a much better understanding what I was dropping into the life blood of my engines. I maintain 5 vehicles now so I'm constantly doing something automotive wise just wish I knew this back in High School Auto I would have saved so much and not damaged what I thought I was protecting. Thank you Lake look forward to more videos.

[@robertmaybeth3434]

I'm your age and I still remember back in 1977, when I pulled the oil pan off my 1964 Plymouth Fury, with the 318 engine, that my dad gave to me to fix up and drive. The engine had about 80,000 miles on it, when I removed the oil pan for some reason I can't remember. But I do remember being impressed by the amount of sludge I found. There was several inches of sludge inside the approximate color and viscosity of dirty vanilla pudding. I cleaned it out with a putty knife. Yeah, I think oils today are a whole lot more improved since then -

[@NotHarry-er3wg]

I fell upon this channel by mistake. What a wealth of information. Really makes me rethink some things I thought I understood real well. Thank you Lake! Ahh yea! I subscribed! My most favorite oil is Mobil 1 5w30 extended performance. After a timing belt failure at 138,000 miles, the engine burned 1qt every 500 miles,.I belive the rings stuck. after trying differant weights and brands of oil for months. Ruining 2 PZEV cats under the 150,000 emission warranty from Subaru I tried the m1 ex per. Imediatly the consumption was less. She now has nearly 190,000 miles and burns 1 qt every 3000 miles and has for years. Thanks

THERE ONE WAY TO INCREASE THE FLOW OF AN OIL FILTER WITHOUT DECREASING FILTRATION IFFICIENCY. THAT IS USE A FILTER WITH BETTER FILTER MEDIUM BUT USE A TALLER FILTER WITH MORE FILTER AREA.

[@usocrazy6133]

This is why I love KZbin University. We get to see Lake "The Motor Oil Geek" but really "The Motor Oil GOAT". As a DIYer and one that wants to keep my cars/truck running at their best I love The Motor Oil Geek channel and the fact he will corroborate with other KZbin channels to educate us. Lake will never tell you a brand that is best. However, Lake will tell you what chemistries are the best. Lake guided me to a cure of fuel dilution problems in my Cummins through using diesel fuel additives. It turned out to be carboned up injectors. I settled on Howes Diesel Defender, again Lake did not suggest a brand. The fuel dilution issue disappeared within a couple of treated tank fills. I am a huge believer in used oil analysis (UOA). You don't know the actual health of your engine without data from doing UOA. I will add Howes Diesel Defender to every diesel fill up. Thanks for answering my question on liquid titanium. I used it a bunch from the Kendall brand. Kendall recently changed their formulation to be more in line with Dexos and no longer has the liquid titanium additive. My cars seemed to like it. I just tore the valve cover on my daughter's 2003 Dodge Caravan to change the gaskets. I expected to see sludge. Everything was clean. I suspect that it may have piston deposits so I switched to Valvoline Restore and Protect so we'll see what happens. I will be doing UOA to monitor the process. Again, Lake had a huge influence on my maintenance. Keep up the videos Lake! You are truly the GOAT of Motor Oil Tribology. Sharing your knowledge makes better DIYers out of the average Joe and we appreciate you.

I’m going to start using your oil analysis on a reman AMC 360 engine that I’m in stalling my 1978 Matador Coupe. I’m starting out with the Gibbs break in oil you developed. Looking forward to learning.

[@jamesgroessler1053]

Im loving this channel. As a Caterpillar Mobile Plant Mechanic, so many people have so many opinons regarding engine oil. I have gained so much information. When it comes to different brands, your video doing the oil change on the boxer. Change the oil twice, sample the oil and look for wear under 5 parts per million. That what the engine likes regardless of marketing. Another brilliant suggestion, look at the fuel dilution and then treat with injector cleaner. I can go on ie dont add additives and changed the chemistry. Best engine oil channel for learning by far!!!!!

I knew an elderly retired pilot who flew radial engined aircraft in the 1950s. His job that took him into Alaska. He would do his maintenance in super cold weather, and for an oil change he'd just drain it onto the ground, wait a while and roll it up, throw it into the trash can. Interestingly, flight manuals and FAA methods manuals tell how to dilute oil with fuel to compensate for the cold.

Thank goodness for the The Motor Oil Geek. Finally someone who knows what he's talking about. No bullshit tests, just technology and chemistry. I own four vehicles and always rely on my oil analysis for what grade and brand I use. Presently using two different brands and four different viscosities. Test results do not lie. Have used most every brand on the market in the past 40 years and always refer to/rely on my analysis results. As for the AMSOIL product, none of my engines seem to like it.

[@charlesb4267]

You have me quite curious at that comment about the Amsoil and refreshing to see someone not falling for a sales gimmick of exclusivity and high price which a few other oils out there are on that theme as well. Since Amsoil isn't for the most part sold in stores or in other easy to access physical retail outlets I have never gone down that rabbit hole ( I can't stand the Amway theme of marketing anyway ), I had only used a bit of their full synthetic automatic transmission oil years ago in a power steering application due to the superior flow in extreme cold weather as synthetics were hard to come by back in the 1980's for all applications. But back to your findings, what was showing up in your engines that did not like their formulation over some other brands ( by the way what brands/viscosities are you using currently ? )

[@tech50349]

@@charlesb4267 Although always within specifications, I did not like the viscosity break down(CST), sulfation and oxidation values. Had better results with other oils. Also had decreased fuel economy over two engine platforms of 0.3-0.4 mpg. Why would someone pay double the price for a product with a less than comparable result? As for present oils in use: Castrol EDGE 5W30 and 10W30 Pennzoil Platinum 5W20 and 5W30 Pennzoil Ultra Platinum 0W20 and 5W20 Will be experimenting with Valvoline Restore & Protect on my oldest vehicle(24 years old and 500K+ miles) as I'm curious. Will also give LIQUI MOLY a try as it's now readily available in Canada. Cheers Charles

[@spankyham9607]

I put a set of total seal gapless top rings in my SBC 400 about 14 years ago now, and I will say that besides having better dynamic compression, it does keep the oil clean because it helps to seal things better. I really am a believer that they are worth using, if nothing else than keeping the oil cleaner. Much less carbon blow by into the oil than normal rings. So when you talk about carbon in the oil, gapless rings work great for that from what I have found.

He makes a good point about oils... and about being able to use not for purpose oils... I once got stuck in the middle of nowhere in my old AW11 MR2 when I noticed a lower than normal oil pressure indication (not no pressure, just low).... Instantly pulled over.. Checked my oil level. Dipstick was totally dry... Called up my dad who was an aircraft engineer(dayjob) and racecar engine builder (weekends)... He said "You have any oil at all?". In the boot I found I had 1L of black as tar SAE30 used oil out of my lawnmower, and 1L of Brand new Redline MT90 gear oil (BLOODY EXPENSIVE STUFF!). He said "Tip it in. Any oil is better than no oil!. Then stop at the next place you find that has motor oil that is the right viscosity. Change it to that. We'll flush it and do the filter when you get home".... Hey it worked!. That little 1980's engine lasted me another 120,000km (280,000km total). Not bad at all for a 1984 4A-GE that had me running it to the redline around twisty mountain roads far too often.

Thank you Lake for another great informative video!! I didn't see it live, in fact I had to watch in shifts, lol. Your oil filter info is intriguing, I have used the higher end filters, thinking I was getting max efficiency, but they are "guaranteed" for 25K, so by definition are less efficient. I'm never going that far, but if it's 99+% efficient @ 20u I'm in. Lots of talk about Fram cheapening it's XG (Ultra Synthetic) filter by eliminating the wire backed full synthetic media & replacing it with un-wire backed layered cellulose/synthetic. The old media (OG) was tested by Ascent testing & was outstanding @ 10u & 15u, Fram advertising says the new media is even more efficient. I'd love to see more videos on filters!!

Although you are based in the USA and this brand is not really known or widespread in the US, i would love to see you test their Full Synthetic Ravenol VMP SAE 5w-30 and the already mentioned Ravenol UFE SAE 0W-8.

Truly excellent.. best coverage on the subject I've seen. Thank you very much!! For best protection I will now use 5w20 dexos EP oil in my Ford derived 5.0 2013 Land Rover lr4 and change it every 4 to 5000 miles. Land Rover originally specd 5w20 and then superseded with 0w20 recommendation. There's a lot of speculation why... seems CAFE likely reason.

I do enjoy this channel. Its a bit technical but I like that. I have just bought an old 2007 Avalon with 62K. I am just going to use OEM filters and change my oil every 3 to 4k with cheap synthetic. This time its Costco oil. I change it so often that the cheaper stuff will likely do just fine as it always has.

I never used Amsoil because I thought it is too expensive and they said you can go 25,000 miles between oil changes, never would do that. I never go more than 5,000 miles. I always thought the oil is expensive because you buy if from independent distributors who have their own markups.

[@ziggyor]

without a doubt the best video yet! I learned so much. Ordered 2 oil sample test kits. Pls Pls Pls have these sessions once every month or 2, and deep dive into the topics you mentioned like filters. Thank you again and so much!!

[@themotoroilgeek]

Thank you and I appreciate the feedback!

[@ashley.vanvleck]

What a great video! Thank you so much

Hello Lake, I am wondering if you have ever done a video/analysis for oil run in newer diesel engines. I just submitted a sample, and some of the numbers were not maybe where they should be. In my 2021 Cummins, I run 5-40 Phillips Gaurdol. I would love to see a video on oil for diesels.

[@themotoroilgeek]

Thanks for the suggestion and for sending in the sample. Diesel oils are on our "to do" list for 2025.

[@mordaccadrom250]

Thanks Lake.... You did a great job on the live streaming stuff. I learned a lot and really enjoyed the informal, relaxed format. So what if it ran into a long video..... that just weeds out some of the folks that are not as into it as others. I think doing one of these sessions perhaps once a quarter or so would be a cool idea. If folks don't like the long format, there are plenty of channels to choose from LOL. I like the fact that you are not in any brands pocket and just simply lay out the data as you see it. Great work and thanks again!

[@themotoroilgeek]

Thanks for the feedback! I had fun doing it.

THE OIL RABBIT HOLE... The application, environment, type of fuel, metals being protected, and so many different things impact which oil is best for your application.

[@Oldclock-lp7is]

Lake ... you are awesome! I've learned so much from you. I truly appreciate your knowledge and hard work to educate us. I've recently made my first purchase of Driven oil for my '69 Corvette. I also have a '69 Triumph Tiger motorcycle that needs your oil. Looking forward to using your oil analysis in the future. Thanks again.

The more time the more I like, I love learning!

[@JoseDelgado-ho1cf]

Listening to your stream, I kept thinking about AMSOIL. How AMSOIL has additive packages that do not meet the specifications of my 2.7 Turbo DI engine. My choice is the Pennzoil Platinum 5W-30 Full Synthetic Motor Oil (Dexos 1). I think I've gone full circle with my thoughts of the manufacturer recommended oils now. Love love love all the info in this stream. Good stuff.

[@darrylsjodin7184]

Amsoil part numbers DP020 and DP530 meet Dexos D. 0W-20 and 5W-30.

[@darrylsjodin7184]

@@JoseDelgado-ho1cf If you mean licensed, not sure, but the data bulletin says it meets Dexos D

Superb video Fun fact. What’s the difference between water and oil? The viscosity of water doesn’t alter with temperature (whilst as a liquid, and it actually does increase in density at 4c, but let’s keep it simple) Imagine if oil didn’t alter its viscosity with temperature? It would be a different lubricant world we would live in😀

[@themotoroilgeek]

Great point!

[@jackharding98]

Thanks for the lesson, I'd have watched and learned for four hours. You are really appreciated. 👍

[@themotoroilgeek]

Glad it was helpful!

[@paulnewton943]

I enjoyed this so much and looking forward to the next video. Would love to see more on transmissions auto and manual and lets not forget a the final drive too.

[@goinwheelin]

I worked as a lube tech in the early 2000s and would pore over all the literature our distributors would give us. Isodewaxing, hydrocracking, differences between conventional and synthetics etc. that way I could explain to my customers why I was recommending an oil for their application. Even though I no longer work in the industry I am still fascinated by this stuff and I have to thank you for putting out this information. It’s been refreshing and I have learned new knowledge about lubricants that I will share with others especially “flushing” with a little bit of oil when you change brands because the different additive packages can be detrimental to each other, that’s something I wish I had known back then. Again thank you and keep up the good work

[@MikeyAlbertin]

Awesome video and thanks Lake! Great information and I did not know all the extra stuff motor oil companies have to do to meet that DEXOS spec. Definitely going to watch video again.

[@themotoroilgeek]

Thanks!

Fantastic Q&A video! Thank You for sharing your knowledge, insights and passion.

[@SP-ro7tb]

Extremely well thought out content and presentation. Thank you very, very much!

[@TheObiwantoby]

I'd like to see specifications tackled head on. That is to say if you have 4 oils that meet 229.52, that there is actually value and noticeable results if you use one or the other at recommended intervals? There are two camps. 1. Use the cheapest oil that meets spec, change often, get oil analysis. 2. Buy the best boutique oil for your application, it makes a difference if you want to keep your car long term.

[@jasonbrown4795]

Thanks for the video. I didn't watch live as it's too early in the morning in New Zealand, but like each of your videos, I learned plenty.

[@themotoroilgeek]

Thanks for watching!

[@GetOffMyyLawn]

Finally subscribed after watching so many of your informative videos! It's great to have fact base info vs speculation and conjecture.

[@zspred]

Great information! I used to use expensive "boutique" oils every 5k. After I started doing UOA's, I switched to quality FS oils I could buy at local big box stores and change my oil twice as often and filter every other oil change and still spend less than what I was on 1 oil change with "boutique" oils. The car does mainly short trips.

[@MrsSunshine75]

@zspred Go-ahead and change that filter with that dirty oil in it every time. It doesn’t cost much and your engine is worth it!

[@Bobthebuilder.69]

​@@MrsSunshine75you beat me to it. Why spend 20+ dollars on oil and not spend $6-10 for a filter?

[@zspred]

@@MrsSunshine75 It's a cartridge filter. The housing is drained. I changed the filters the first couple of times, but they still looked new, so I went to every other on them.

[@arxigos365]

@@zspreduse high quality filter like wix xp or Purolator boss and keep it longer.

[@Phantom-mk4kp]

​@@MrsSunshine75If the oil pressure is still good, the filter is not restricting flow. It was quickly mentioned in the video that a used filter can be more efficient at filtering, if not clogged than a new one
