I know there is information on this but I tried a search with no luck.
My Newmar Bay Star is due for a oil change. I intend to use
full synthetic oil and a top end Fram filter XG-2. The F-53 chassis has the Triton V-10 engine.
Fords Chassis Owners guide recommends 5-20 Synthetic blend changed at a maximum mileage of 7500.
I also think extending the interval to 10,000 miles should be OK since I generally drive on highways at constant speeds. We are full timers and
spend 2 to 7 months at a location.
I have used full synthetics in my autos and usually changed them at 10K with no issues.
Any thoughts on this. Bob
