Save Money On Gas 1.0

Dont drive. Dont drive a car when you dont have to. Ridesearch or Carpool, walk, take the bike, or take a bus. These will not only save gas, but also will help save our environment and may be better for your health. Do you really need to drive to the store that is only a couple of blocks down the street?
Get a better air filter. More efficient brands of air filters cost a little more but will pay for themselves in most vehicles in fuel savings.
Get Low Resistance Tires. Some tires, such as Michelin Energy MX 4 Plus are supposed to increase gas mileage.
Use the lowest recommended octane for your car. The lower octane gas is cheaper. Most modern cars are engineered to run most efficiently on lower octane fuel, and often recommend not using higher octane fuel. Check your owners manual to be sure, as not all car engines should use lowest octane gas.
Get a membership card. Some gas stations offer membership benefits. There are also department and grocery stores that give discounts at the fuel pump when you use their store membership cards. Make sure you understand the benefits; getting a 5-cent discount on gas that consistently costs 10 cents more than the next guy isnt much of a deal.
Give your car a tune up. While properly maintaining your car wont actually save you money at the pump, it will save you gas. Using less gas saves you money. Have the oil changed, and have a certified mechanic give your engine a look over.

Buy a Diesel. Diesel cars can often get better mileage than comparable hybrids. Getting a Diesel car also allows for use of Biodiesel or even Waste Vegetable Oil (WVO/SVO) fuel.
Buy a hybrid car. Not only do hybrid cars give you immediate savings at the pump, the U.S. government and your local state offer tax breaks for people who use gas-saving cars. Federal deductions for using gas-saving cars can be as high as $2,000.
