Gas Milage With Lift

[JLS Photo]

I've got about 500 miles on my 3" lift with 33" Ridge Grapplers, and my new gas milage is TERRIBLE!

I'm currently getting about 260 miles per tank. Roughly 17 mpg highway, 14 city. I mean, the truck looks freaking sweet, but I didn't expect the MPGs to drop by 30%+.

Anyone else seeing this?

Did you recalibrate for the tire diameter if different?

Im not surprised at all

I had a f150. No lift. Just Went with larger tires when OEM wore out.

P series to a couple size larger LT series.

Mpg went from 21.4 to 17.8. And that is without the lift.

Are Ridge Grapplers mud terrain? I'm running 285 Falken ATS (almost 33") and getting 24+ on highway but it's not lifted yet.

Im with hounddog, seems reasonable with 3" and 33,s

I'd say it has a lot less to do with your lift and a much larger tire. You went from a ~30ibs tire to a ~60-70ibs tire.

Anecdotal proof of this...still running stock 265/65r17s with the Icon lift & I've only dropped to the low 20s for highway mpg

The dealer did recalibrate.

That's a good point. Thats an extra 120+lbs of rotational weight.

Oh well. it looks sweet and I'll be off roading in the mountains. Just kind of surprised me.

You could look into lighter wheels to offset the weight a bit.
I don’t know what’s out there but Centerline had some back in the day.

A gear ratio change may be the best option though.

I’m lifted to 3.5” with 20” Terra Grappler tires and getting about 19.5-20mpg on a 40mi HWY commute to and from work. Staying on cruise set 3-5mph over and letting the adaptive cruise do its thing.

Edit: running premium 91 octane.

 

[MTB-BRUH]

This is exactly why I’m keeping stock tire size and no lift. Still looks decent

I'm running +3.5" w/ 285/70-17 Ridge Grapplers. I also dropped the front spoiler and put the FX4 skid on, which probably impacted things. All said, I dropped down to about 17 Highway/15 City. Got the Livernois 93 Octane Tune, and that put me back at 21 Highway/18 City. The tune will pay for itself in time.

Staying around 20.5 MPG total and close to 24 MPG highway with this setup. Have to expect a drop in mileage with any lift or heavier tire.

That looks good.

You mentioned in another thread “2.5” leveling kit and 265/79R70 tires on stock wheels with 1/4” spacers.”

Can you verify that tire and wheel size again?
