I was watching the Pa. 500 today and there was one car which was being driven in one gear. You could see his tach go to about 9400 before he let off for the corner. It went the whole way albiet shortened to 425 I think. Now I sure would like to know what oil they are running in that car! I was some impressed. Any espionage efforts will be appreciated. RW

That was Ryan Newman and the Penske South operation is sponsored by Mobil One.

I know a few people so I'll ask around. I do know there are all kinds of honest-to-God snake oil salesmen ofering al kinds of wild concoctions to teams. It is really crazy in the sport.

Thanks much, Bretfraz. The guys at work this morning are telling me that all the oils and fluids in these cars also have to to certified by Nascar as being what they say. I suppose that still leaves some room for different compounds in the case of Mobil 1. Regards, RW

ultimate additive system for
high rpm, high speed, high temperature conditions where thermal
stability and the prevention of
oil thinning/breakdown are essential.
