Oil specs
My question - what is the difference between M1 Formula M and M1 European other than the viscosity if any and is there a significant difference between the 0w40 and the 5w-40 oils? Can anyone give me a reason to choose one over the other?
TIA, Mike.

I'm sure that they will all do the job but does anyone have any preference?

I agree they are all about the same and if there is a difference it will be so minor as not to bother: remember you are changing it every year or 7,500 miles with filter, whichever comes first.
My choice would be: whichever is cheaper!
The same for both cars? The R230 is normally aspirated 8 cylinder and the E-300 a 4cyl turbo. The E-3000 specifies MB 229.5 type oil requirement which makes things simple but I can't find the same spec for the SL. Do you know if the SL also calls for 229.5 type oil?

Also with the rebate, it's $12.88 for a 5 quart jug of Mobil 1, vs $15 for Costco oil.

In short it doesn’t matter. As long as it meets the MB spec and is changed in the MB interval.

I'm going to just use the European 0w40 in both.
