Could someone tell me what kind of oil I should run in my b18c turbo? It is bored to 81.5mm, stroked to 95mm, and running a T3/T4 .60/.63 turbo. I heard that it is bad to run synthetic oil through a turbo motor as well. The motor is freshly rebuilt, any advice?

 

if your motor is not broken in yet dont run synthetic motor oil in it.

just run regular motor oil for a few hundred miles then switch to whatever u decide

this is the procedure i followed
