What oil?
Still has the original oil in it of course, but what grade and brand is it?
Is it dino or syn?
I always thought you used dino oil until the engine was broken in, but has that changed?
I want to drain this out and put in fresh with a new filter.
What brand filter needs to be used? I know this engine has the oil condition sensing system in it, do you have to use a GM filter or can a Napa or k&n be used as well?
thanks
