Turbo oil

What oil i use to 2tr-fe TURBO

 

Definitely use synthetic, due to the higher temps the oil reach with turbo added. I would talk to the person/shop who installed the turbo, they would know the additional stress placed on the engine and an appropriate oil to use. If you installed the turbo, you probably know enough to select a good oil for your application.

I think Castrol Edge 5w40 would be a good choice.

This article says Pennzoil Platinum 5w30 is approved for turbo applications - see notes at bottom:

My brother runs 0w-40 in his 300ZX Twin Turbo. Alot of oils will say "recommended for BMW and Audi" and thats usually because they generally use turbo charged engines these days so they may work well too.
