Is my mileage unusual?
I towed for over 10 years with a Ford V10 and averaged 8.25 mpg (nothing any better than 9.65). I've been towing over the last year with a Ford diesel and like the way it tows, however, the best mpg ...

tbax46,
I don't have to lie as I have an accurate log of every gallon our truck has had put in it and every mile it's been driven to where and what was was behind it or on it as it's only used for our RVing and WE ordered and purchased it new so we are the only owners and drivers. 45 Rico____ always sticks his nose into other people quotes with his nonsense OPINIONS! He absolutely knows nothing about my truck or how it's driven and sure looks stupid claiming he does!
I'm a retired automotive engineer and engineering business owner working with the Big 3 mainly on pickups, vans and suvs. for nearly 40 years. Real hands on experience counts and many of the forum posters rattle their lips and fingers about something they only have opinions or at most read about on forums that fits their tainted agendas and post their ignorance and gibberish without any real education or knowledge on the many forum subjects. IE backyard mechanic wannabees!
tbax46, many things will affect fuel economy. A few are: You waste fuel you had paid for by any fast acceleration starts or not letting your speed drain off by itself rather than hopping on the binders to slow down. You used your fuel to move the load to it's speed driven so why use your brakes anymore than you must to negate the fuel used? Also the aerodynamics of your 5th wheel will easily affect your MPG's. Air resistance uses 2 times the amount of fuel on average at to move your rig at 58 mph on flat level ground at sea level at 68 F than it takes to overcome it's rolling resistance. 3 times approx at 70 mph.
Tire type/tread type and inflation really matters as less inflation for example means a larger tire footprint on the road surface wich is added friction and tire sidewall flexing. Multiply times number of tires you have on the road. Looks like you have 10 tires on the road surface so it's 10 time the one tire's additional road friction. Really adds up fast!
Your 4.10 ratio surely doesn't help fuel economy at highway speeds but helps in getting the rig rolling quicker. Additionally, I surely have no idea how well or efficient your engine is functioning and that could be a big part of your excessive fuel use. Any absent minded pumping or not necessary up and down action on your accelerator wastes fuel. Obviously and headwinds or grades really affects fuel economy. A partially carboned up (semi-plugged) catalytic convertercan drastically reduces engine efficiency/decreases power output while still consuming the fuel. Is your fuel filter system needing replacements? A fuel starved engine has a loss power and efficiency.
No, I can't tell you specifically why "you" are getting such poor mpg's as it may be in driving habits, engine system issues, aerodynamics, tire issues, even roads/topography where driven or a couple dozen other factors or conbination of factors. An answer to your thread question: YES, your mileage is unusual! It's lower than it should be in mpg's! It's your truck and you are driving it so you will have to work at finding out why. No magic answers!
