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'll go with what the manufacturer suggests, unless, one of you have millions of dollars for research and development, and can tell me different and back it up with solid proof. I don't have that much money, so I'll trust them, and use what they suggest.
