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

from the folks I have talked to, the Ford gas engine has lots of power, and very poor mpg....I owned a 2010 Jayco Seneca with a Duramax Diesel and averaged about 9 mpg...my new 16 Excusion has 50 less HP but is a pusher, and I am easily averaging 10.4 mpg when towing a Honda CRV....it comes down to "if you have to know the mpg of your motorhome, you probably shouldn' own one"-----lol

ps....note above that I do know my mpg, but still own one....
