jim,
yes, I get better mileage, motor revs faster...and it certainly takes less freeway driving to get the oil up to the operating temp.
Is the car more powerful? I don't know since I don't have any dyno chart to prove that.
Oh yeah. GC 0w30 certainly runs better in a Ferrari Enzo than some Shell 10W60.
