I can't remember where I read it but, I heard not all NASCAR teams run synthetic motor oil in their engines. Is this true? Do some really use just plain old conventional motor oil?
I know that many teams like Ryan Newman run a 0w-5 oil for qualifying then switch to 0w-30 R. Don't think Amsoil is found in any pro-NASCAR teams. Differentials is another story.quote:
I've heard that at least four NASCAR teams run AMSOIL Series 2000 0W-30 for qualifying. I don't know what they switch to (or that they switch) for the main race.
The original formula for Series 2000 gear lube was put together to keep The Unser's Pike's Peak differentials alive. "AMSOIL is the Best Lubricant made, the Standard by which all others are judged." Bobby Unser
They only run 1 or 2 laps for qualifying.quote:

It is called MARKETING...not racing.
Umm, have you been following any current racing rules and technology, BBY? You have managed to sandwich (club sandwich, actually) valid facts in between some pretty thin speculation and plain ole nonsense.quote:

Yeah, but would you do the same if it said 'Brawny"?quote:

As far as I understand, the NASCAR rules for using the same engine for the whole weekend have degenerated to the heads, crank, rods, and pistons have to stay with the engine--even the carburetor can be changed excepting the restrictor plate at restrictor plate tracks.quote:

With the new rules do they not have to keep the same oil in for the next days race?
