I track my car. It's a 2008 Tib GT with the v6 motor. The track sessions typically last 20 minutes. I've used multiple different oils and i'm honestly not sure which is best to use, for multiple different reasons.. I've used Mobil 1 and the OP starts off at a good 80psi at 6,500rpm and then goes to 65psi 15 minutes into the session. Weight was 10w-30 Then tried Valvoline synpower, same thing. Tried Rotella T 15w-40 and that was the only oil i've used that was able to keep the OP above 75psi for an entire 20 minutes. Problem is i'm not sure how my motor is reacting to rotella t, so I went out and bought a jug of Valvoline synpower 10w-30 to swap out. Plus.. i'm not sure if my oil pan is baffled. I run Hoosier R6's. I haven't run into any oil related issues with my motor yet, but I don't know how to look for them. I'll take my valve covers off sometime next week and inspect my cams to check if they're getting proper oil. Just wondering what the better motor oil is to run when tracking the car.
