With gas prices hitting record highs all across the country, many people are looking to reduce their driving or invest in more gas-efficient cars.

All good ideas, but if you can't afford to do either one of these, how about improving the gas mileage on the car you drive today?

It's relatively easy and doesn't have to cost you an arm and a leg.

The first place many auto experts suggest you start is your tires. Check the tire pressure and make sure they are properly inflated. Under or over-inflated tires reduce your gas mileage.

If you don't already have one, go and purchase a tire pressure gauge at any local auto store or automotive section of your favorite big box store.

Check your owner's manual or the side of your tires for the proper PSI, or pounds per square inch of pressure recommended. Tire pressure can fluctuate greatly so check your tires at least once a month.

The next place to go is your trunk. Take out any unnecessary weight like those golf clubs or cinder blocks which are weighing down your MPG's.

Also, if you're one of those with the classic "Colorado Coffin" or bike rack attached to your roof, remove them and watch your mileage improve by reducing extra drag.

Another good place to look is under the hood. Check your car's air filter. A dirty air filter can make it harder for your car to "breathe" and thus reduce gas mileage.Air filters are cheap and easy to replace yourself. Check your air filter every month or so.

This next step usually requires a mechanic for most. Proper maintenance or tuning of your auto will not only give your car a longer life, but reduce the number of times your hitting the pump. Regular oil changes (again check your owner's manual for the maintenance schedule), fuel filter changes, belt replacements and tune-ups are a very good idea.

And finally, the way you drive not only says a lot about your personality, but has a dramatic effect on your gas mileage. Avoid fast starts and stops, use your cruise control as much as possible and reduce your speed.

Safe and happy driving!
