I recently bought a Winnebago with a Ford V-10, 41,000 miles. Oil was clean but will be changing it soon, as a maintenance precaution.
I was going to use regular oil (Brand name) but am still considering Mobil 1 full synthetic.
I have heard that at this age (2000 chassis) if I go to synthetic, I may experience oil leakage due to nature of the synthetic oil.
Anyone have any experience (or problems) on changing over from regular oil to synthetic oil at this point?
