Get your husband to do it for you then.

I think our window sticker on our 02 limited with the 4.7ho said 13 city. Up on all maintenance, stock, and 78k miles. I get around 12 to 13 regardless of how I drive, and it always drops in the winter.

Not sure if it's it because it's a V8 or what... But my 4.6 stroker is sitting on about 3.5 inches of lift and 265/75/16's and I still manage to get 16-17 MPG.

I suggest you run your tires through this as it will give you the exact percent you are off. My V8 with stock tires varies from 14 to 18mpg depending on driving and conditions. I just had my worst tank of gas at just under 14mpg but then we had a huge cold snap and crappy road conditions for a week so I expect it will get better. Air filter, plugs, run some BG-44 through to clean the fuel injectors. All told you might have $60 invested and you will probably see some improvement. I'm reminded of what I was told when I got my first Jeep and noticed the mileage sort of sucked, "You didn't buy the Jeep for the mileage, get over it".

Still true six years later, if you bought your Jeep thinking it was a fuel efficient vehicle, then you have only yourself to blame.

Get in there with a spanner and treat her to some Lurv'

Start like the others say with a good service. Its amazing what happens with just a new air filter alone. So get a routine service kit and get it serviced - plugs, filters etc, etc then work up from there.. do the simple things first, clean the throttle body until spotless using carb cleaner will help.

I had a Passat VR6 once that was renowned for misfires and heavy on the gas. On their forum board there was a lot of complaints of low 20's and early teens on mpg when the text book says it should return 34mpg! I spent ages making sure mine was in total rude health, new leads, coil pack, full service, new MAF and guess what.. I did get mine to 33/34 mpg but as I say the car has to be in total RUDE HEALTH!

So don't come on here and b1tch about it if you're not prepared to get your hands dirty...

I think I may check my brakes bc they seem like they need a little help. The pedal travels farther and takes more pressure than should be necessary to stop. I'm also getting a lot more brake dust build up on my right front wheel. Maybe the caliper on that side is sticking?

Idk, just kinda bummed I find this great dub and the dang mileage sucks!
Stupid $3.15 per gallon gas!
If you have a sticky caliper, you will lose mileage.

Right now, I'm getting on average between 10-14mpg. My last tank I got 10.4, and that was with a 25km trail run, and a 1.5hr drive on the hwy with 20psi in the tires (I know, should have aired up, but there was close to an inch of ice on the rims and it was -18).

We get better mileage up here.. less air so engines burn less fuel at the same AFR, more coasting down hills.. too many tourists driving 10 under the SL..

Because a half Way glogged filter will refuse the pressure from pump making the injectors spray poorly.

Wj Wj mpg

Your MPG is actually pretty close to where it should be. I have a 02 WJ Laredo v8 2.5 coils in front 2.0 in rear - running 265 -70-17 Sra-s. Thule Moab rack with rear hitch tire carrier for my spare which doesn't fit inside the Rigs compartment - yeah check your plugs and fuel filter. I'm still new at everything Jeep with this being my 1st wj after owning 3 xj's - so it's just my 2 pennies.

But, the complaint about mpgs is moot. These only got 14mpgs in the city from the factory. You're a fool if you think youre going to get better than that after a lift and larger, more aggressive tires. 12 is about right. I get 12.5 but I travel one 55mph road for 20 miles to work every day.
You'd probably use rolling circumference, not outside diameter (well, I guess that feeds into the calc. too, but anyway). So it'd be something like 99 inches versus 91 inches, about 8%. So yea, pretty close right?
