Increased MPG?

[pronstar]

What is your final drive ratio?

You likely need to gear down...though you won't get great MPG with tires that big.

I own a 28ft. offshore fishing boat and on those, you drive by the tachometer, that's how I drive my car. Getting used to that mindframe is easy, and your gas mileage will improve. Anything below 12mpg and there's something wrong, either with the driver or the car..

I agree.....When i bought my 2000 EB the guy said he was averaging about 10mpg. I took it, had the fluids replaced, the fuel injectors cleaned, added an Intake and was easy on the gas pedal (which is hard to do cause you just love to hear that exhaust rev up) and I haven't even added my Throttle body spacer yet and i'm averaging about 14 with mostly in city driving. If i can make it to 16mpg i'll be happy....cause my last suv was a 6 cyl Blazer and i got about 15 on average lol

My 2000 5.4 was getting about 12.5 mixed driving. I changed the fuel filter and it went up to around 13.5. I am 1000 miles into my 2500 mile trip from Anchorage to Seattle and I am averaging 17.4. This is manually figuring the milage, not a trip computer. I am very happy with this. When I budgeted the fuel I did it figuring 14 to 15. The most I have had to pay for gas so far was $4.82 in Whitehorse, Yukon. The highest I paid in Alaska was $3.19. If I had gone another 1/4 mile I could have got it for $3.06

I averaged just under 20 running across PA from Cleveland to Philadelphia earlier this month. No trailer. Cruise set at 65mph most of the time. Rpms under 2000 in 6th gear.

6th gear? When did they start putting 6 speed transmissions in the expo's?

 

[chuck s]

2007 and 2008s have six-speed transmissions.

No choice of engines or axles. The 4x2s have 3.31 and the 4x4s have 3.73.

Limited slip is gone too and replaced with traction control.

Since the newest Expeditions came out. Really helps with acceleration.

Damn, that's really nice. To bad i still like the body style that i have over the new ones Maybe they'll revert back one day and i'll buy a new one when this one blows up lol

I got just under 20 mpg running the width of PA to Philadelphia and back last month across I-80 crusing in the 65 - 75 mph range. RPMs at 2000 and below.

Both the computer and my pencil matched to a couple 1/10ths.
