If you are not going to run the BD Turbo Oil, I would recommend running a good synthetic 2 Stroke oil. Preferably the same as what you are running in your motor. The bearing "seals" on a Garrett turbo, are not what you would traditionally call a "seal" and do let a little oil out into the turbo. It is a very small amount, but it can get into your motor, so you want something that is not only good for your turbo, but also that your motor can burn properly.
