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 would go with the guys on the internet that have far more miles on their engines. like I said Ford decided the 5W30 wasn`t right for my V-10 and said to use 5W20. many people by the time they said it was OK to switch had well over 100k mi on their motors with the 5W30.
so with that which oil would you use?
What guys have far more miles than the ford engineers have access to?
Which ones have access to the repair records of thousands of engines, so the can see the statistical differences?
It's probably not the end of the world to use 5W30 but to claim that since you got 150k miles, you know better...I'm not even sure where to go with that.
