Chnage your air filter, also change your spark plugs. This will help with gas mileage. Also check the pressure in your tires, tires that are under-inflated cost you gas mileage.

The easiest things to change are your air filter and spark plugs. This will increase air flow and make a bit more power also. The best thing you can do to improve economy is eliminate weight by swapping in lighter aftermarket parts.

One thing that you can buy at the local auto store is a K&N air filter. This will help with mileage by up to 10%.

The best way to improve the gas mileage on your SUV would be to replace the air filter on it. Once you replace the air filter you can expect to get about two more miles per gallon.
