5w-40 oil

[ctimgo]

I get that 0-w40 is ok but in the owners manual it show that 5w-40 is good for temp ranges above -13F. That would leave me to believe that 0w is for colder than -13F. I can't ever remember it being -13F here. We are lucky to see 10F one day a year so I am wondering if 5w would be better protection on start ups.

The Owners manual was written 20 years ago. Much has changed in the oil world since then. The Mobil 1 formulation and particularly it's additive package has had several major changes.
In terms of current Porsche Approval(paid endorsement!) - Mobil 0-40W is one of the the correct oils- unless we know better !

I know we won't use it.
