Are All Motor Oils the Same? Let’s Find Out!

Aviation vs Car, Diesel Engine, Motorcycle, and Marine. Brands: Mobil 1, Phillips 66, Motorcraft, Quicksilver and Motul. I paid an independent oil testing lab to analyze all of the motor oils, and I performed my own testing for lubricity, resistance to thermal break down, and oil flow characteristics.

I bought all of the motor oils, paid for the oil analysis, and all of the supplies used in this review. I always pay for everything out of my own pocket to ensure an unbiased review. So, THANK YOU for supporting the channel.

We need a video on Valvoline restore and protect

Heya, great video and it was of especial interest to my wife and she was the lead chemist in the evening for 28 years at BASF and made a lot of this oil. She was very interested to see you boiling your oil as she says they used to put it into a platinum (and yes, they had to lock it up in the evenings) crucible and bake it for an hour at 600° in a muffler oven. She says that your test with the coffee pots and the heater plate actually seem to be very accurate. Good job, as the scientist, she really enjoys your videos at a level that I cannot match. You’re very creative.

The information you provide us with is so invaluable. I want to start giving back for all the help you given me in deciding different products will give me the most value and ultimately saving me money. I appreciate it

*As a 20 year Locomotive Machinist, (retired) I spent a lot of time going over motor oil lab test results. We actually had our own Oil Testing Lab. Every single Locomotive that came into the shop or across the Service Pit, for service and/or repairs was required to have to its oil tested...The test results always gave you the most information & told you more than any other test what's actually going on inside the engine. The test results are stored on computer hard drive and the Machinist could look up the history of any given engine, going back to the engine's original installation date....Great diagnostic & education reference. A good example, you see an oil test with elevated copper & lead particles, that told you that you had a bad bearing somewhere. If you saw elevated chrome and/or iron levels, that meant you had a bad set of rings or scored cylinder walls. Excessive carbon in the oil meant you had a crack in the water galley beneath the exhaust manifold...(the block is thin there)..If you saw borate (railroads put borate in the engine coolant water to help identify leaks)..in the oil, it meant you had an internal water leak in the engine..ect., ect., ect...*

2:17 Power Smoke engines? Nice little sneak in there.

I love that you tested this. I followed your earlier oil testing like they were playoff games.

This brought back a funny memory. In 1975 I bought a Ford Country Squire station wagon with a 352 CID motor from a buddy for $60. It had a serious lifter clatter on cold start, and I lived in Rochester NY at the time. But I was working at the local airport as an aircraft refueler and didn't really know a lot about cars at the time. So I did an oil change using 50 weight straight weight aircraft oil. After that, whenever I started it, it sounded like washing machine filled with nuts and bolts. Rattled like all hell! But after a few seconds, it would settle down and run great with no clatter. I drove it like that for about a year before selling it and getting something "cooler". Should have kept it!

0:52 Filling them to the very top and no leaks... very impressive!

When my aircraft boss was a young mechanic in Alaska they temp was below - 50 F. The choppers required heaters in the engines to make the 50 WT oil flow on startup. The oil came in 50 gallon drums with a hand pump to service these aircraft. After - 40 they had to build a bonfire under the drums to get the oil to go from a sludge solid to more of a liquid. I was fortunate to turn wrenches on the turbines which use oil so thin it's almost the same viscosity as water. Thanks for the oul episode my friend I appreciated it.

One day, there will be a store called Project Farm and each department will be the top choice for sale with empty shelves because you sold out everything. Great work, Todd.

I would love to see a video like this but comparing 2 stroke oils. Comparing lawn equip like Echo/stihl to marine and motorcycle 2 stroke oil

Worked for a forensic geochemistry lab for over 20 years run by a professor from UCLA. I happen to have been an avid Harley motorcycle rider and since I had a laboratory full of testing equipment I ran tests on every brand of motorcycle oils to find out who made Harley oil so I was able to identify by the additive package added to the oil who made the oil so I could save 65% on my purchase price.
All of this comment is to just say that every manufacturer has its own additive package that it supplies in its brand of oil.
Our ability to test oil could tell you which oil field in the world the base oil came from whether it be from a Middle Eastern country or a Pennsylvania sweet crude West Texas light on new or old product we tested a lot of samples.
In short this Bio marker program had fingerprints for every petroleum product made around the world.
It was fascinating working through the development of this whole testing procedure program.

I've always loved your hot-plate switching regimen. It speaks volumes for your care and objectivity in testing. Great job as always!

14 minute video & 45 minutes reading comments I always get my money’s worth with your videos. Thank you Sir

[Mhoward]

A head to head test of various radiator system flushes/cleaners is something that no one else has done.

[chrisa]

Oil reviews never get old! If you haven’t yet, suggestion of best oil filters would be great!!

[brentjones]

My kids (5, 9) are absolutely addicted to your tests, they come around every time i watch

[dentalnovember]

I love how you are included marine and motorcycle oils. You are my go to for product testing. Keep up the good work.

[markspence]

This is a WONDERFUL video!! It is making me open up my organic chemistry textbooks again, and try to rationalize why metals and oils behave the way they do.
