My motorhome is a 1988, 26 foot Tioga Class C mounted on a Ford E-350 chassis. The engine is a Ford 460 cu. in. V-8, the vehicle has 38,000 miles on it. I am only getting 5 to 6 miles per gallon with this vehicle. Is this the best I can expect with this motorhome and engine?
Please let me know if in your experience this is approximately the mileage I should be getting. Last year I had new plugs, wires, filters, etc. changed. I did not have any work done to the fuel injectors.
Regards
Dennis
