Everyone with oil temp issues

rbratton

What is your basis for saying that 260 is too hot? I spoke with an engineer at Exxon today that claimed Mobil 1 synthetic oil does not even begin to break down until temps are above 400 degrees. He said the oil will perform excellent at 260 degrees. Is there something else in the engine that fails above the aforementioned temperature that I'm not thinking about?

Like I said in my previous post, I tracked my car last weekend at Barber in Birmingham. I have the Stillen cooler; with ambient temps in the high 90s, my oil temp was at 260 by the second lap and stayed there for all 8 twenty minute sessions. I never experienced limp mode...

Also, I inquired about oil temps in other track cars and 260-270 is common even amongst M3s.

Again, why 260?

I'm inclined to believe 260 is fine...
