MPG - List your rig and your MPG
Ok, so I'm curious to see what everyone else is getting on their rig and/or what they've done to help with MPG.
My rig is a 4.0, inline six with 42RLE auto. transmission. Mine when stock: 15 - 15.5 MPG - Automatic 42RLE, 3.73 gears, 30x9.5 GSA Wranglers Mine after mods: 11.5 MPG - 3.73 gears, 3-4" lift, 32x10.5 Super Swamper Radials I lost a whole lot of gas in the mod process which bewilders me. According to this chart, I should be getting the most fuel economy with 32" tires but, obviously, I'm not.

The guide is just that, a guide, it doesn't portray actual figures or specific results per mod, being that there can be multiple factors that effect gas mileage.
I'm getting 16mpg on 33x12.50R15 MT and 3" of lift with 4.56 gears. I think I have a cracked exhaust manifold, so hopefully it will go up when I get that fixed.

That "better" gas mileage column doesn't mean you'll get better overall mileage, it just means you'll possibly get better mileage than with the ratios shown in the other two columns. There's no free lunch where bigger/heavier/harder-to-turn tires under a lifted Jeep encountering more wind resistance is concerned.

00' 2.5L 4spd, 4.11 gears, 32" Goodyear MTRs
15-17 mpg combined Your swampers probably have twice the rolling resistance of the GSAs. |

'03 with 4.0, manual, 3" lift, 32" tires, 4.10s, lots of city driving and heavy foot - ~12mpg with a hard top on.
Gets about 12.5 with the soft-top. Was getting about 13 before the roof rack, tire carrier bumper, armor, etc.

97 with a barage of CEL and sensor problems--2.5 ax5 w/4.11's and a 2"bb with stock rubi tires and wheels. 15mpg no matter what. Oh, but I do have one of those new fangled airaid intakes that the PO put on. That must have given me a good extra 40 horses at the rear wheel!
