#24 of 43 Re: Poor MPG? [fordexpo] by wvgasguy Jan 30, 2009 (4:20 pm)
Replying to: fordexpo (Jan 24, 2009 4:00 pm) I wonder why people buy these Expeditions,Tundras,Tahoes etc and then complain about gas mileage with these 6000 pound bricks.   We buy them because we need (or think we do) a vehicle this size. We complain about the FE because we would like the manufacturer to concentrate on improving the FE. I don't complain because my Expedition gets 14 mpg. I expected that. What I do complain about is that they don't do something about it. I'm not talking about major gains. But the difference in 14 mpg and 17 mpg is pretty significant.   I would have went for a diesel option, even at the steep premium if it had been available. Would have loved a hybrid option like in the t'ho.   For me, I complained BEFORE I purchased. That does not keep me from complaining after too.   Chevy has a good idea with the hybrid but messed it up putting it out as a $50 vehicle. I believe if the mgfr's come out with a large SUV under $40K that gets 20 mpg they will sell well   Besides that, I am interested in FE so I also drive my hybrid as much as possible.
#25 of 43 One thing that may help _ Expedition by wvgasguy Jan 30, 2009 (4:23 pm)
The Expedition has such a mushy ride that I have to slow down for curves and then speed up when exiting. I believe that hurts my FE considerably. If they would make the thing handle better I could drive more steady and possibly help some Replies to this message: harborharley (May 17, 2009 6:34 am) tidester (May 17, 2009 12:50 pm) harborharley (Jun 12, 2009 4:17 am) and 2 more...
#26 of 43 Taking it easy by wvgasguy Jan 30, 2009 (4:28 pm)
When I drive my Expedition like I drive my hybrid I can get 18+ on driving that is mostly highway. Driving over 65 mph kills FE. Driving in town kills FE, even with slow starts starting 6000 pounds from a dead stop takes a lot of gas
#27 of 43 Expdition Mileage - Disconnect Battery by eagle1990 Apr 16, 2009 (5:53 am)
Replying to: markm828 (Jan 22, 2009 10:03 am) Ive got an 05 4x4 Expd w/ 46k miles - Usually get 18+ highway & 14+ city mpg. Recently dropped a lot (to 14 and 12). Tried a K&N air filter, injector cleaner, higher octaine gas - to no avail. Disconnected the battery (to reset the computer chip is what i was thinking) and my mileage went back up to 18-20 highway. I am very happy. Replies to this message: tidester (Apr 16, 2009 10:17 am)

Replying to: wvgasguy (Jan 30, 2009 4:23 pm) You probably need new shocks/ better tires. The Expedition is not a sports car. I have 97,000 miles on my 99 and it's a great vehicle. I did replace the shocks and I am on a new set of tires. I get about 18 mpg on the hiway under the best of conditions. Driving under 65, not doing fast starts and conservative driving helps millage. According to the Newtons law F=MA, going faster is not going to help gas millage. Increasing Mass or Force or both is going to take more energy. You can't possible get better millage going faster everything else being the same!   Has anyone tried a new muffler system such as Magnaforce to reduce back flow??

Replying to: harborharley (May 17, 2009 6:34 am) You can't possible get better millage going faster everything else being the same!   I get exactly 0 miles to the gallon when I am idling at full stop. Increasing my speed does, in fact, improve my gas mileage.   tidester, host SUVs and Smart Shopper Replies to this message: harborharley (Jun 12, 2009 4:17 am) tidester (Jun 12, 2009 6:57 am) harborharley (Jun 13, 2009 4:49 am)
#31 of 43 Mileage When Towing a Trailer? by buffalojoe Jun 11, 2009 (8:59 am)
I have a 3500 lb. RV trailer that I'm planning to tow with my '99 Exp and it has the 5.4L. I just bought it so I could have the comfortable car for such a trip and I don't have a feel yet for the mileage. Anyone have a ballpark idea of what mileage I could expect when towing? Thanks!

Replying to: tidester (May 17, 2009 12:50 pm) How do you increase speed when at full stop at idle? Replies to this message: tidester (Jun 12, 2009 6:57 am) harborharley (Jun 13, 2009 4:49 am)

Replying to: buffalojoe (Jun 11, 2009 8:59 am) I have the 4.6 L engine in my 99'. I towed a small motorcycle trailer with my Harley on it on a camping trip recently. I hardly noticed any drop in mileage. How ever, it has low weight and wind load. A 3,500 lb load is going to cut down mileage and I would guess about 3 mpg depending on how you drive. I would certainly keep at 55 or lower. Getting that rig moving is going to eat gas, so try and gradually build up speed and coast to stops if possible. Use brake as little as possible and allow plenty of space for stops and no sudden sharp moves. Make sure your tires are all up to proper pressure. Check your hitch and safety chains, make sure all your lights are functioning. Replies to this message: buffalojoe (Jun 12, 2009 7:42 am) harborharley (Jun 13, 2009 4:56 am)
