This past weekend I went to my first high performance driving event on Summit Point Racetrack - Shenandoah Circuit.
I am driving 2001 twin turbo Audi S4, car is modified(chip, intake, suspension, brakes and downpipes) but for this event I put the stock chip back in so boost and power were at the cars stock level (250HP and 258 Tq).
Car has 129K miles and I use GC with 4oz maintenance dose of Auto-Rx. Normal driving oil temperatures are in 210-225F range.
During the weekend we had 10 track sessions 20 min each. I noticed that in the morning sessions oil temperature would be just slightly above 250F toward the end of the session(outside temps were in the 60s), however later sessions in the afternoon would have oil temperatures around 275-80F (outside temps in low 80s)
Car has low oil pressure warning but it never came on even with this high oil temperature.
Can GC handle these kind of oil temperatures or should I look into 5W-40 weight oil and will that give me adequate protection for track at these oil temperatures or is oil cooler necessary to keep oil temps under control?
