Default Cruise Control!

I'm getting just under 16mpg with 95% highway driving. Of course, he's only two weeks old and will get better. Cruise control really helps. It's just a straight line down the highway to work with little traffic so I set it to cruise, sit back and watch the DTE counter go up Then I get back into the city and watch the gas needle drop like a stone

I was getting 18.5 or so in the city. I got about 24 on hwy. Since the weekend I am running 33's and can't freakin' get the dash to go any higher than 15.9mpg. Well, at least I didn't buy it for fuel economy.

Significantly better than the Ford F-150 with the Triton V-8 that I traded in on the Rubi.

You will have to convert the difference in size of your 33's from your stock size tires you maybe getting better fuel economy than you think!

whooaa - if dash is that far off im in single digits

Dash says 12.5 mpg (heavy-footed suburban driving, auto 4-door with 4.10s & stock 32s). The MPG went down from ~13.5 when I removed the stock front bumper and put on an Olympic Rock bumper & JCW grille guard.

I found that if you keep your fingers off of the reset button for a while, the dash mileage will line up very close to computed mileage (miles since last fill divided by number of gallons to fill tank). I track every drop of gas and track it in a spreadsheet (obsessive-compulsive?)

Road Trip 1, mostly highway, Arizona mountains: Dash 18.8, Computed 18.8.
Road Trip 2, all highway, towing 3500# camper: Dash 15.6, Computed 15.5.
Off-Road Trip 3, almost all off-road: Dash 12.8, Computed 12.9.

Of course, reset before you go down hill and the Dash will beat most Hybrids! Reset again before that long climb to the top of the mountain and... you get the picture.
