Alot of oils threads are out there, but I won't be "that guy" and tell you to search.. lol.
The weight is dependent on the bearing clearances and desired oil pressure. I run Rotella 15w-30. |

Still on the vf39? Some aftermarket turbo's require that you run an oil with high ZDDP in it, aka racing oils. I used to run Rotella T6, but with the new turbo I'm going to run Redline synthetic 5w30.

Amsoil zrod 10W40 in the winter and Amsoil dominator 20w/50 (or is it 15w) in the summer.
Imo Amsoil makes the best oil. The racing formulas have a very high zddp content. Here is a chart you can consult and pick your own. http://store.forcedperformance.net/m...otor%20Oil.pdf |

AMSOIL, Shell Rotella T6 5w-40, Motule 300v line, Mobil 1 0w-40 Euro. Any of those. Assuming the engine is broken in of course.
