What oil are you running?

[DIESEL_POWER]

so the benifit from running 20w50 over 15w40 is better wear protecion on the bearing and such? does it make a big difference running this in the winter months??

20- 50 over a 15-40 on the street has no bennifit,it's worse protection in the cold. raceing however it does have it's bennifit,20-50 will protect better at high heat and stress levels.


I use amsoil 15-40 or the new 15-50 racing oil :ylsuper:
