GT[23]ers, [for those unix users out there]

I use Mobil 1 in my 996 GT3. Right now I have 0W40. I used to use 15-50, which I don't see any more, and Mobil is making several new viscosities.

What is the right (or best?) viscosity to use on a track car?

TIA, CIA, ETC,

Mine has Mobil 0W40. Doesn't burn a drop. At least 5000 track miles.

Porsche Motorsport uses (used) M1 0w40. Both the 911's and the RS Spyder. At least that was what I saw from Sebring 2007.

Just as Brant said, the race teams use 0W-40.

well then --- if Motorsports uses 0W40, so can I !

case closed.
