Fuel prices have been at record levels around the United States for the past few weeks. Now is a good time to review ways to improve your gas mileage with your Jeep. Now Jeeps were never designed to be be efficient like a Toyota Prius with 30mpg +, but there are some tips you can use to get the most out of your Jeep's fuel economy. -Keep Your Jeep Well Maintained. Make sure your Jeep is up to date with it's maintenance and service. A tune-up could mean all the difference. Adding a cold air intake and a Superchip Flashpaq Tuner can also help your engine run more efficient. -Keep Tires Properly Inflated. Under inflated tires aren’t just dangerous, they kill fuel economy by as much as 30%. Overinflated tires aren’t efficient, either. Also keeping your tires balanced and in alignment will help you at the pump. -Lighten Your Load. The lighter your Jeep is, the better gas mileage you will get. I know some Jeepers that get  crazy with this. They will remove the rear bench seat and spare tire. This is a big reduction but you don't want to be stranded on the side of the road with no spare tire. Some will only fill up there gas tanks half way at a time. This method is best for around town and local trips. A half tank of gas will save you about 60-100 lbs. How you want to save weight is ultimately up to you. -Driving More Efficiently While each Jeep reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 50 mph. Idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner (AC) use. Turn off your engine when your vehicle is parked. It only takes a few seconds worth of fuel to restart your vehicle. Turning your engine on and off excessively, however, may increase starter wear. When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear as well.
