My C-32 was apparently factory-filled with Mobil 1 Tri-Synthetic 0W-40 oil. Do you suggest this weight for use in Las Vegas where winter temperatures rarely, if ever, fall below 30 degrees F?

That is really odd... I thought all MB runs on Mobil 1 15-50. I ran that on both my C43 and C36. Hmm.

Each dealer varies with what viscosity they use from what I am told. Most out here in California use Mobil 1 0w-40.... I personally like Mobil 1 15w-50 myself. Both viscosities are ok to use per the service and spec manual.
