What oil do you run in your 2ct?

[TheCrippler]

What type of oil are you guys running in your diesels? Anyone noticed any difference in brands or weight? I'm coming up on a oil change and thought I'd see if anyone had an opinion.

I live in Los Angeles. Pretty mild climate most of the year.

I've ran both 10W-30 and 10W-40 synthetic blend.

i am using rotella diesel 10-30w in my 3L. (1 gallon jug is cheapest at wally world)
i use it in my other older (non diesel, flat tappet) motors.
