For those seeing high temps without coolers.

IMHO though I know Mobil one runs well in csertain types of autos. (I swore by it in my Rx7), it doesn't seem to do all that great in my Z. In my G35 I used Castrol syntec and it seemed to do pretty well. But to me, it seems EDGE, truly has an edge over the outgoing syntec. I feel a noticeable performance increase. The 1st 500 miles didn't seem all that impressive on the Edge. Then all of a sudden the car felt more powerful and much smoother. The good part was temps drop after about 250 miles. So I'm extremely pleased with EDGE as a performance oil.
