5W-30 Oil test videos.....
 

Guys i found a video online comparing BMW 5W-30 Against Castrol 5W-30. At the end of the video you can see that after being boiled at 400 degrees one oil leaves more sediment than the other. My question for the oil gurus is, does this test actually simulate engine oil under extreme heat conditions such as track driving? Also what is the machine used to boil the oil and where can i buy those glass test tubes, if this test is accurate i would love to purchase a kit like this and do my own testing.

If a test like this is accurate i guess the video proves my theory that not oils are created equal even with a simple test.

Found two more videos:

0w-40 test:

BMW uses Castrol as the oil for its M cars. I wonder how "Original" their oil is.

Can someone do the same test with Motul and Subaru brand 0w-20 oil?

MOTUL 300V please ! Not the 8100 !

Maybe if you got boiling oil in your engine you need to look at something else than the oil you're using lol

Where to start? High temperature stability is just one aspect of oil performance.

Deposits are caused by oxidation to create heavier degradation materials. So what you see left behind could be degraded polymerized lighter materials or just heavier higher boiling materials. So less deposit can mean better oxidation stability or it could be that the one with lesser deposit just boils off at lower temps, so higher oil consumption. There is no discussion about that.

Oils are multifunctional products that have to perform in many different ways. There are and have been lots of very specific demonstrations such as this over the years that focus on one question, but ignore everything else.

To choose an oil based on one demonstration like this would almost be like buying a car based only on the fact that it had 17" wheel as opposed to any other size and ignore all other criteria.

I wouldn't waste your money to acquire the capability to do this. You would be better off discussing your application requirements with an oil manufacturer technical help desk to determine why on an overall basis their recommended product is better for your specific needs. Note, I did not say best, because there are enough different requirements that best amongst different manufacturers would be debateable at best.

plus your engine wont ever see 400deg, that will be over 700F..

The easy way to find an oil for the track is to just use a street/track oil like Motul 300V, Red Line, or Amsoil Dominator and be guided by used oil analysis to determine the proper interval. But don't confuse a few uoa's as a tool to compare engine wear or which oil is best. They're better at determining the oil change interval (especially if you get a TBN) and to spot any mechanical problems. There are probably a few 100% street oils that would be fine at the track as well.

I've gotten great feedback from Pennzoil (actually the Global Brand Manager at the time), Red Line, Motul and Mobil1. Actually, the Motul feedback was from the Mid Atlantic distributor, but it's not difficult to contact the Motul USA technical department via telephone.

The more details they have about your specific application the better (typical driving conditions, type of track driving, concerned about being covered under the powertrain warranty or not, etc.).

Yeah, BMW and Castrol are partners. They recommend Castrol Edge anyway so this is kind of weird.

10W60 for the M cars

This feels like those plastic gears they have in auto parts stores where you turn a crank and look at how much better one of the oils perform.

Focusing on one aspect, but not telling us anything about all other aspects
