oil protection ????

whats the best oil for protection? Im not looking to pick up 2 or 5 hp . The engine is making 800 hp and im gonna spray a 250 shot in it. Im using valvaline vr-1 20/50 and plan on sticking with that weight if i switch.

I just don't get it why is everyone running 20/50 it just adds more drag to the rotating assembly if you have good bearing tolerances why not run lighter oil? it is not as hard to turn...

I run the Schaeffer's 20-50, it may be thick but my bearing clearances allow it and as long as the oil sample reports keep coming back like they are its staying in there..............

i run the 20/50 also .... as per my engine builder

In the Valvoline line, the best to use for performance is the VV-851 or VV-855 if you want the 20-50w

Me and Harold was on the phone talking and he said another Co. has the old Kendall GT1 (green) Racing oil formula. I think its called John Penn oil Co. I used it years ago and it got hard to find. Gonna get me some

http://www.bradpennracing.com/ is the old Kendall oil, made in that same refinery that made the Kendall oil.....the Kendall & Amalie trade names were sold off to a third party when the refinery was sold. Good stuff, particularly their break-in oil.

The old Kendall GT-1 rocked. The Brad Penn fills the bill now. Second verse, same as the first...
