2011 EB 3.55 Platinum First tank was 19.4mpg with 10% city driving, but that's computer navigation. I will know better on my next fill up.

I have been driving My 2011 f150 XLT 4x4 supercrew 3:31 gears with a 3.5 Ecoboost, and I have 4800 mile on My truck Now. I have been getting
around 21.5 Mpg to and from work combination city and freeway mostly
freeway about 90% of it. But when I take a trip on the freeway I get 23Mpg if I stay be tween 60and 65mph.

Hey, I have a 2008 Ford F150 FX2 Sport. I am looking for a Fuel Performance Chip that could help my MPG plus maybe give me a few HP. Any recomendations?

Motosoal

according to the truck, on the first 500 miles it's been 15.7

It's been about as much of a mix as you can get as far as driving.

I will report back with some more firm numbers soon.

I was getting about 19mpg for the first 1200 miles or so, but significantly colder weather has dropped me down to about 17mpg and that is on a 34 mile each way commute through rural country. The cold weather/winter fuel really takes a toll. BTW, I don't idle my truck to warm it up; just drive it gently for the first few miles.

I averaged 17 on my way to Colorado and back this past week. The winter and winter blend seem to be taking a toll on my mpg.

I agree. Mine has dropped as well, to about 17.5-19.5 combined depending on the amount of short runs I do.

Mine has droped about a mpg. Still pretty pleased with mpg's though.

Average over the last 10,000 miles 14.6, average over the last three tanks of winter blend gas 13.1. Sweet... It's a far cry from the 17 I was hoping for, but whatever.
