Montana does not have ultra low sulfur gasoline, which means TBN depletes faster. If he's going to stick to factory recommended OCI of 10K miles (is it?), then personally, I'd feel more comfortable with a higher TBN oil such as M1 0w-40.

On top of that, M1 0w-40 is actually cheaper in the US because it comes in 5qt jugs.

M1 Formula M 5w40 has been used in the US for many years.

I know that, but that does not necessarily mean it's a better oil for a gasoline engine.

It's MB 229.3/229.5 and has been the preferred oil for dealer-serviced MB gas engines.

Just like Castrol 5w-40 is the preferred oil for dealer-serviced VW/Audi gas engines. Will it do the job? Yes. But does it mean it's the best option you can get?

I did not say M1 Formula M 5w-40 was bad oil.

About $100 for 9 quarts and the filter. I do my own OC's.

No, MB 229.5 is full SAPS. From what I can tell from the MSDS, Formula M 5W-40 is pretty much all Visom and very little PAO. M1 0W-40 has the MB 229.5 plus several other approvals, higher TBN, and now a GTL/PAO base stock. I am running the new FS 0W-40 in my E63.

Just pointing out if TBN retention was poor, we'd know already.
