Highway mpg?

What highway mpg do you average?

I just went 152 miles on the highway at 70 miles per hour in about half a tank.

that seems unbelievable. I've got I6 with some mods (sig) 5 speed and 6" of lift with 35s..

On my odometer it says ~129 and i dont have a corrected speedo gear

the gear i need for my tires is 29 tooth and now i have 34 tooth gear so to do the math 34/29=~1.17 on other words my speedo reads 17% slower.

129 x 1.17 = 152.1

60 x 1.17 = 70

What do you get?

My Rubi is fairly heavy with winch, armor, bumpers and swing away with 33's.
It runs 450-600 miles a week mostly highway and most of that at 73 mph (speed limit 65). I get a little over 15 mpg.
The dummy light comes on at 234 miles and it will take about 15-15.5 gallons of gas at that point.

All mileage figure with a GPS since you cant just drop a speedo gear in a Rubi

I have been getting about 12 lately. But all my driving is short trips to and from work across town. About 5 miles right through town.

About 16 or so. I avg 15.8 which includes about 5-10% driving in town.

04 Sahara, with a lift, some stuff, and a few things, on some 33's, blah, blah, blah.
A perpetual work in progress. Too much to list, not nearly enough to matter.
My RigRater Score: 387RRv1.0 with a BOA of 18.92 (and just how exactly is this going to help me over that big arse rock?)

I get 150 miles per tank around town @ 15 gallons per fill. = 10 mpg.

Last highway driving I did, I got around 12-13 mpg.


It ain't no fun unless you get some of it on you.
