Sounds like he is all stock so no recalibration should be needed. We have no idea what he thinks is poor fuel economy.

WaterDR Folks, lets be clear, unless the thing is getting poor mpg for a jeep doing that maintenance will do nothing.

First, get a baseline. If its in range, than that is what it is.

Atthehop Fill the gas tank.
Note the odometer reading.
Drive it til the gauge is on E
Fill the tank.
Note how many miles you drove and how many gallons you had to put in to fill the tank.
Divide the number of gallons into the number of miles you drove.
Now you have the accurate MPG. Well almost.

Do this ten times and average it out.

If you do not know how to average it out let us know and we will help you. It's obvious you do not know how to calculate MPG.

Also, maybe changing out your o2 sensors "may" help as well. I've just changed all 4 of mine with NTK's as part of my maintenance as they never been changed. Plugs are new from day one of owning my jeep last summer. At first it seemed ok for milage but as winter set in, winter gas blends will be your achilles heel depending on location of course. Besides if your still getting under 4$ a gallon, be lucky. I pay around 5$ a gallon or 1.31$ a liter in my corner... Im sure in Europe they pay even more then I...

As they say, dont like it? Get a prius!!!

try going from a geo to jeep.
honestly, change plugs, air filter, oil, and O2's. I battled bad mileage for a couple tanks, bit the bullet and did the sensors.

WaterDR Define bad?

If you are getting 15 mpg and you hate that then sell it.

If you are getting 10 mpg then you have a problem that needs to be fixed.

If you are getting 14.5 than check the air in your tires etc..

Above all else, don't have a lead foot.

Just offering some help.
Rule 1: Please use the search function first
Rule 2: Don't complain about mpg's while driving a cube.
Rule 3: Don't ask about "the wave"
Rule 4: Just drive it and have fun...oh yeah, wave!

you may have to drive a bit further to get a better idea of the avg mpg. And you definitely can't just go by with what the gas gauge says, it's not very accurate.

When you did the math, how many mpg are you actually getting when you fill up? miles driven divided by how many gallons you put in.

Atthehop Take the money you would use to buy the MPG devices that claim to and buy gas.
02-24-2013 09:11 AM
Crazyflyingplastics Not much, you are driving a brick down the road. Change all fluids and spark plugs can sometimes help. How many mpg are you getting? Do you have a lift, big tires, etc...? I get right around 14 to 15 mpg...that's pretty normal.
