Personally, I’d say to not get caught up in the uber oil chase as it’s throwing money out the window. Practically any oil available today (in the correct viscosity), is of more than sufficient quality.
I’d focus on regular oil change more than whatever uber oil at $$$$ / quart (i.e. Motul). And no need to over-change Oil change with every 4 Autox events??? AutoX events are IMO, pretty mild on motors. Very little relative full throttle compared just about every other venue, including commuting and fwy on-ramps 🙂
As for:
[quote]I guess they did this is that most people were just grabbing any sort of synthetic and sticking it in their cars, and it was causing problems[/quote]
Don’t give BMW too much credit, it likely was all money driven.
That said, Mobil 1 is no longer fully synthetic unless you get into their Delvac lines. No issue for autox as again, there’s not real heat with short bursts of accel.
T6 Rotella are fully synthetic so this is likely a nice price point for good stuff.
One of my cars specs 12qts of molasses grade 15W-50. Trying to find a good value for that oil change is futile.
