What would be the pest oil type for a turbo d16 at 10psi?

 

Redline or Royal Purple. Mobil1 if you can't afford the others.

 

ditto

 

wait....how many miles are on the motor?

 

92K but the hed is going to be pulled and replaced.

 

As long as you use the proper weight and change your oil regularly the brand makes almost no difference (i.e. super cheap stuff might not be the weight it says it is). The filter you use makes MUCH more of a difference.

The only reason to use synthetic is to go for extended intervals without changing, you should still change your filter though.

 

Ok, what about a special blend due to high RPMs? (8k)

 

Don't recall of such an oil existing (even if one did seems like a bit of a scam). Usually you use a heavier weight oil when the RPMs (and turbos), hence heat, are high.

 

+1 I also like amsoil as well.
