With the addition of a turbocharger (M20B25) what are y'all running mileage wise for oil changes? I run 20W50 semi-synthetic and was previously running 5k oil changes N/A per Black Stone Labs recommendation when I sent an oil sample out. I suppose I could just send a new sample and get some data at 3k miles, but I was curious what kind of mileage everyone else is running.

2500ish on 20W-50 VR1. Might be overkill but oil is cheap. -
Clearly it depends on your use case. A full synthetic should generally be safe for 7k these days, but the additive package isn't likely to be designed for the rather antiquated E30 designs.
I was running M1 in 20w-50, or 15w-40, depending on availibility/season. Quaker has some nice oils in one of their oils, but nothing "heavier" than 10w-30, which should technically work.
At last check VR1 had a light or zero detergent package, short interval would be key there.
Whatever the case, BitOG is the best reference I know of, even if it's not what it once was.Comment

I'll update the thread if blackstone has any insight for the turbo bois. Castrol GTX has been my go-to, at least N/A. We'll see how it holds up to the heightened turbo temps.Originally posted by MrBurgundy View PostComment
