I'll probably catch flak for this, but are you guys running 0w-20 or 5w-30 for autocross?
I ran Motul 0w-20 last year (first year with the car) and didn't notice anything terrible about it. On my WRX, I ran 5w-40 when 5w-30 was recommended, so it feels sketchy running a 20 weight.
I know 5w-30 is recommended on these cars for "track use" to keep oil pressures up. The highest my oil temp got was ~240ish on the 0w-20 in grid after runs. I never saw anything near the 270 mark.
