change your spark plugs if they haven't been changed in awhile. check your tires for the propper psi there should be a sticker on the inside of your drivers door that will tell you recomended air pressures go by this not the recomendations on the tires. also where are you getting you gas does it contain ethanol sometimes this can burn faster.

SOURCE: poor gas mileage on my jeep liberty

Did this happen overnight or was it a gradual loss? Did you do any kind of repair before you lost the gas mialage? Is there a check engine light on or did it come on and go off? Did anything weird happen before the jeep got bad gas mileage? It's hard to diagnose a problem like this without actually touching the car.
Any other info might help me steer you in the right direction.

when was the last time you put in fuel injector cleaner? I put in Lucas Oil Injector cleaner every other or every oil change.

There are alot of factors affecting your gas mileage. Tire wear, tire pressure, wheel alignment, air filter, fuel filter, spark plugs, oxygen sensors, just to name a few. So to say what you need is just shooting in the dark without more information. I would probably start with your oxygen sensors, and then perform a tuneup. If your vehicle pulls to one side or the other when driving on the highway you need to stop into the shop for a wheel alignment.

How can i get better gas mileage out of my liberty


  1. change spark plugs @ 30k miles
  2. change air filer,consider a more efficient filter such as K & N
  3. avoid 'jack rabbit' starts & stops
  4. try premium gas-the 'cost' per mile may outweigh the MPG on regular.
  5. check & maintain proper tire pressure.

to increase gas mileage make sure you keep on top of tire air pressure you can also have your tires filled with nitrogen instead of air also a K&N air filter does wonders and is good for lifetime worth every penny. another smart move is to use a fuel system cleaner regularly Lucas makes great products for this try local parts store.
