For fellow boosted D-series guys: I am in the process of building my D16Z6. T3/T4 Turbo 60trim, fully built bottom and top end. Stock calls for 5w30 oil, I'm pretty sure this is too thin for the new setup. So the question is simply what oil are ya'll using, less brand. (I use mobil 1) Sorry if this has been covered, my searches were returning nothin.
