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....

I have never used anything lighter than Mobil 1 5w-40 and have used 15w-50 for the majority of the 50,000 miles I have put on my MH. It's running as fine as when I bought it with 30,000 miles.

You guys do realize that in other parts of the world, not subject to US emissions laws and corporate average fuel economy, that same V-10 engine is specified to run on 5W-30 and 5W-40 oils.....
And as point of discussion, mine has run a very happy life (based on real oil analysis) running on Rotella T6, as do almost all of our engines.
