Tried to search this but I wasn't so successfull. i'm just wondering what grade of oil you you guys are using on built motors that are pushed hard and making lots of boost.

Thanks!

Why the higher front number? Isn't that a little thicker oil?

Higher temps?

Yup, nothing like hot lapping the car in 105+ temps. I'll give it a break after 3 passes though to let it cool.

10w 30 or whatever else is in the garage... I think I had some 10w40 lying around for this oil change.

whatever decent oil is on sale, penzoil, valvoline, castrol etc. 10w30 in the winter and 10w40 in the summer, I change it pretty often though.

I'm with KP here, I just use a good name brand oil and change it often. I generally use Valvoline because I know someone who used to work for them and they actually said that they buy the best crude (or whatever) and make the best oil. I run 10W40 all the time, but I don't drive the car much in the cold weather.
