With high fuel prices on the minds of most Americans, finding ways to be more economical and fuel efficient are on the rise. So what can you do to save money? More and more automakers are developing new, easy to use tools to help drivers keep an eye on fuel efficiency.

* Make sure your tires are properly inflated. According to the U.S. Environmental Protection Agency, you can improve fuel economy by about three percent by making sure your tires are properly inflated, but not enough people do it. The U.S. Department of Energy says nearly four million gallons of gas are wasted each day nationwide for every one psi of tire under-inflation. That translates to more than $10 million per day, or $3.8 billion per year in wasted gas money.

* Test your vehicle's emissions systems to make sure the engine is working efficiently. Fixing an engine that has failed an emissions test may improve gas mileage by four percent, on average. That's the equivalent of 12 cents per gallon.

* Change your car's oil and filters regularly. Changing the oil regularly (as recommended by the vehicle manufacturer) will increase the life of the car's engine. Clean oil reduces wear caused by friction between moving parts and it removes harmful dirt and grit from the engine. The car's air filter keeps impurities in the air from damaging internal engine components. Not only will replacing a dirty air filter improve fuel economy, it will protect the engine. Clogged filters can cause up to a 10 percent increase in fuel consumption.

Or better yet new hybrid cars are an excellent choice for anyone looking to save money at the gas pump and help the environment. Many car manufacturers are making hybrids because they are small and fuel-efficient. They are powered by a combination of an efficient gas engine and by electric motor that helps with accelerations. Batteries that recharge automatically power the electric motor. On this Hybrid Cars site you will find a large selection of topics covered with expert advice and tips for anyone considering the purchase of a hybrid car.
