Using lots of gas

Take it in to have the engine gone over, and a tune-up. Tire pressure affects gas mileage, air filter, fuel filter, etc.

Is the check engine light lit? If so get it scanned. Old tired O2 sensors can cause poor fuel mileage.

Check the tire air pressure, drive a little slower. Over sized tires will reduce your mileage.
