I have got a 2001 Fleetwood Bounder 32H with a Ford Triton V10 with no owners manual for the chassis. Has 15k miles on it. What engine oil grade would be best ?
I'd go with full synthetic, 5w-30. I am proud to say I DO think Supertech oil from Walmart is absolutely fine stuff. Meets all the regulations and has fine reviews from bobistheoilguy.
