V10 Motor Oil
All, Well, I've done it now. I brought home a new class A. Mine is on the FORD F53 chassis. The oil fill cap & owners manual state it is to use 5W20 motor oil ? WOW! That sure is thin....

You will get all kinds of comments here, so I will start. I have driven our Ford V10 Triton over 80K miles so far, and have always used full synthetic oil, generally 5W20 Castrol. As far as the mileage goes, the oil weight is not going to make much difference.
While not as many miles we have only been 36K in ours we live in So. Cal where everywhere we go is either up or down a hill to any distance! :B Like Johno02 we have run the full syn that came in it followed by Castrol full syn 5/20 for all those miles. We run close to GVWR/GCWR on most trips including high heat 100+ in the desert never an issue.
