have you asked other ppl what they are avg with mpg. terrian, elevation, temps can all play a role in the mpg you get.

Ive conducted a test the last 2 days on the drive home, I even have pictures I will load later for proof:

@ 65 for the 30 miles from on ramp to off ramp I = 23.4 mpg

@ 70 today i got 21.4

Ill just drive 70.

*edit*
Coming home at 65mph a day ago, 65ish degrees, light wind. I had just tapped the break as I took this.


coming home today at 70mph, same weather conditions:

When I researched getting a truck, fuel economy wasn't even in my mind.

As far as fuel economy goes, the main thing is, don't drive your truck like a sports car.
The speed limit is the maximum - doesn't mean you have to maintain that speed...I usually drive just under that, unless it's a single lane highway and it's busy - then I do what the traffic is doing...

As someone else already said, you may save yourself like what, $20 a month in fuel?
Don't know what it costs to chip your trucks down there, but up here it like $400-$500...plus installation...that means it would take you approx 3 years to recover that expense.

Adding a Tonneau cover improved my fuel economy a bit - but that wasn't the main reason I got one.

I'm also not interested in summer tires and winter tires. (again - cost to change them out twice a year - is it worth it???)
I use Goodyear Wrangler Silent Armours which are winter rated and give me good traction around the field on our hobby farm and in the snow.

Curious. Ive read wear leveling or raising your truck lowers your MPG, what about dropping the back end so it is level with the front? Would that make any changes?

I have a 2010 with the 5.4 engine as well. The absolute best fuel mileage is obtained at 50 mph. As you found out, slower = better mileage.

Your time is valuable too. I don't look at the pump $$$ while I am filling up...

Depending in what state you're driving in ... 50 mph would be hazardous on the highway to other drivers doing 70+ mph. Drives me nuts when I come up on these idiots driving Toyota Prius's trying to save every nickel watching the little Eco meter inside.

Speed limit is 70mph on the highway to work. The cops will give you to 75 before they pull you over. If you do 50, they might pull you over for your own safety. Not to mention the bicyclist out there would be passing you.

The best way I know to improve gas mileage is to drive 65 mph and keep it tuned up, or better yet............... leave the truck parked in the garage sorry, had to throw that in.

haha...The only other option is riding the Harley. When its 40 degrees outside...its not very fun for riding.

My FLTRSE3 was lucky to get much more than 30mpg so the HD isn't much of a fuel saver.

These mpg threads continually amaze me. 18mpg, 14mpg I could care less. Over a year at 15000 mile average what is it? $15 or so a week? If that is a concern you probably shouldn't own what you have and get something less expensive.
