Hi guys. I ran in an HPDE at Texas world speedway in a stock SS this weekend. Oil temps were at the third tick but pressure was same as street use. 3rd gear on the track to redline with a 3-4 shift on the main straight.

I am using Pennzoil Ultra Euro 5w-30, which is a European spec oil with an HTHS of 3.7 (meaning it holds viscosity at high temps). I get it on Amazon. Might be worth trying.
