Hay shed at P.I. is a 180+ right hander in a car with good rear end grip.
I have a 1994 R32 with a stock bottom end. So far 7 events with oil filled to the top of the dipstick "hump" with Castrol Edge 10W60, so good. Have had 3 20 minute sessions at P.I. with no issues.
That said, when the engine comes apart for a refresh - every manner of oil control issue will be addressed.

Andrew
