1. Check your air filter

• A dirty air filter restricts the flow of air into the engine, which harms performance and economy.
• Air filters are easy to check and change; remove the filter and hold it up to the sun. If you can't see light coming through it, you need a new one.
• Change your air filter every 10,000 miles.

2. Check your tire pressure

• Check your tires when they are cold (driving the car warms up the tires and the air inside them, increasing the pressure), and keep them properly inflated.

3. Slow down

• Try driving the speed limit for a few days and you'll save a lot of fuel and your journey won't take much longer.

4. Accelerate with care

• If you drive an automatic, accelerate moderately so the transmission can shift up into the higher gears.
• Keep an eye well down the road for potential slowdowns. If you accelerate to speed then have to brake right away, that's wasted fuel.

5. Get back to nature

• Consider shutting off the air conditioner, opening the windows and enjoying the breeze. It may be a tad warmer, but at lower speeds you'll save fuel.

6. Clean out your car

• The more weight your car has to haul, the more fuel it needs to do the work.
• If you're the type who takes a leisurely attitude towards car cleanliness -- and I definitely fall into that group -- periodically go through your car and see what can be tossed out or brought into the house.

7. Service Vehicle Regularly

• Proper maintenance avoids poor fuel economy related to dirty air filters, old spark plugs or low fluid levels.

8.  Do not warm up your engine

• Drive off immediately at a low speed after starting your car.  This way, the engine will warm up faster and lubricate better.

9. Don't drive

• If you can avoid driving, you'll save fuel. Take the bus, train, LRT, and consolidate your shopping trips. Walking or biking is good for your wallet and your health. And before you get in your car, always ask yourself: "Is this trip really necessary?"

10. Combine trips

• If you can do the several short trips in one longer trip, you will save fuel and time.
