okay, I did a search on this, and I'm just wondering, what is the best weight of oil to use on a turbo car. Should I be using 5w30 or 10w40 or what? thanks guys. Oh yah, it's an h22a1 with about 6-7psi of boost.

 

Depends on the weather where u live...but you generally want to use a thicker oil since the tubo really heats up the oil.

 

I'm going with 20w50 in the summer!
