Best oil for high performance?

I have an 08 with fully built engine and the TRD supercharger. 300+ whp

I've been running 10w30 mobile one but have heard a few people say I should be using royal purple but not sure what kind, 5w40? What do you guys think? I live in Colorado so It gets coooold during the winter too.

I'm a fan of Brad Penn oil. And I always use factory oil filters. Cant go wrong with that.

The viscosity needed will depend on bearing clearances. If your engine was built to looser tolerances than stock you will need a higher viscosity. Like a 40 or 50 weight. If it was built to stock specs than run what Toyota recommends for your climate. Ask your engine builder, they should of told you.
