Any updates to this thread? I'm changing the oil tomorrow on my little HPDE/Club racer 944. Would like to buy the "right stuff". I DO have some left over Rotella T 15W40 from my diesel truck days... Hmmm....

The Rotella 15W40 is THE oil recommended for my son's Subaru WRX and a lot of Porsche "TT" guys use it as well for their daily drivers.
As far as my SP2 car goes, i'm pretty happy with Redline 40W, although everyone has their own favorite brand !

You should use the oil recommended for the car. since my engine is basically 1/2 of the 944 engine, i wouldn't think that anything other than a 20-50 or 15-50 should be used on the track, especially because of the engine's reputation of being starved of oil for its #2 bearing in high g turns, especially with oil that breaks down easily or too light of viscosity weight. what ever is in the Porsche book, use that oil for this car. but, dont use mobil 1, as it breaks down and thins out to the point that it endangers oil pressure overall. motul, redline, amsoil, rotella, all shoulld be fine
