So is that M1 15k (Guaranteed!) mile stuff really good for 15k miles? I
put some in my Suburban, it is at maybe 10k miles now and I am getting a
bit noodgy about it. I guess I should trust it, but all this oil talk
has got me paranoid.

Also, what about the M1 10w-40 "for high mileage engines" would this be fine
for old Benz' and perhaps offer a slight increase in cranking speed on these

Mobil 10W-40 High Mileage is NOT a group IV synthetic oil (like the
Mobil 1 oils) and while it is API CF rated it is NOT approved for
Mercedes engines (may not have ever been tested)!

I'd use Delvac 1300 or Chevron Delo 400 if you don't want to use a real
synthetic.
