Mobil 1.... 0W-40.
But for now I'm using El Cheapo oil 15W-40..cause I'm broke still works though.

 

Castrol RS 10W60 works for me. Good oil pressure even when the oil is a bit hot.

 

castrol gtx 10w30 every 1000-1500 miles here.

 

I just change it with whatever is in my garage whenever I feel like it. that's usually 2-6k between changes, and I change the filter when I really feel productive, again only if I have one.

 

I use mobil delvac 1300 super 15W-40 and not just because I have a diesel turbo :P
I'm gonna try amsoil though.

 

Castrol GTX 10W30 every 2500 to 300o miles.

 

I run 10w-30 in the summer and I guess that's fine, but my Dad said he wants to use 20w-50. Anyone use this? Against it? For it? Thanks fellas!

in the summer i like thicker oils
they give u more psi when ur idling after some hard driving

 

i use royal purple 10w-40

 

Yea. I'm gay. I got it to work. Just cut that black fender guard stuff and it fits like it was made to be turboed.

My Dad says 20w-50 and I have heard what I run now 10w-30 is fine. Then I read someone's thread in FI that they had to get 15w-40 by Castrol and it was for Super Diesel and Turbo Engines. Then of course there is everyone else's opinions on what to use. Sooo....I'm still a little lost. He recommends the 20w-50 so that's why I asked you. How do you know if 10w-30 holds or if I need 20w-50? Thanks again fellas!
