Yeah use Mobile 1

 

that's all i've used for 3 cars, and about 100k miles combined.

never had a problem.

 

I use it. Never had any problems and I just pulled the pan off before I stuck this same motor that was ragged from the 79 into this car and it was clean enough to eat from...not sure what the LS1's problem is...works fine for me.

 

works fine in my 2000 ls1

 

I use it in the engine on my vette and trans am. I just done a timing chain swap in the trans am and it was nice and clean, no residu or film like said above

 

It'll be in the bottom of your pan. I guess I should have taken pics for the non-believers.

 

I agree,

RP makes great trans & diff lubes, but the oil sheets off the cyl walls to quick & does not hold as good of a film cushion for long-term bearing life if pushed to extremes. M1 is what we run in our street to all out race alky motors.

A while back RP was the title sponsor in NHRA Pro Stock and the competitors had to run it. Only way to keep the lower end together was to change after every run. It does make a slight gain in HP due to the sheeting & flow.
