Gas prices and fuel conservation are always topics open for discussion, especially in the summer when gas prices seem to skyrocket. If you want to get more mileage for your money, certain modifications and adjustments to both your car and your driving habits can make a difference. Try a couple of changes and watch as your tank goes further than before.

Instructions
1
Change your air filters and spark plugs as recommended in your owner's manual. If you live in a dusty area or frequently drive on dirt roads, change them more frequently. Dirty filters make it difficult for your engine to function to its highest potential, while old spark plugs can cause increased gas consumption.

2
Replace your oxygen sensor periodically. Old sensors send false signals to your engine that more gas is needed

3
Maintain consistent tire pressure. Fill your tires if you notice they are starting to get low. Low tires cause rolling resistance, which forces your car to work harder and use more gas. Be careful, though, as over-inflated tires can pop or explode. If you're unsure of your correct tire pressure, stop in and see your local dealership or mechanic for assistance.

4
Open your vents. Decrease use of the air conditioner and heater. This will lessen the amount of fuel needed to run the units, thus increasing the mileage you get from each gallon.

5
Decrease your load. Cut down the weight you carry in your car by 100 pounds and you can increase your gas conservation by as much as 2%. Remove unnecessary cargo stored in the trunk or back seats. Remove any equipment racks from your roof if not needed for regular use.

6
Adjust your driving habits. Accelerate slowly to conserve fuel consumption. Drive at a consistent speed as much as possible, as stop-and-go traffic uses more gas than a steady drive. Drive in the range of 55 to 65 miles an hour (always obeying local speed limits) for optimal fuel performance.
