Get more mileage between fill-ups

Nothing lasts forever; that goes for low gas prices, too. As the travel season gets under way, motorists are attempting to get the most out of each gallon of fuel. The media have provided a number of tips. However, some may be misleading or misunderstood.

A motorist called for confirmation of what she had heard on the radio: that you can get better gas mileage if you switch to a higher octane (i.e. more expensive) grade of gas.

Seldom true! Stick with the fuel recommended by the carmaker, as stated in your owner's manual. Under special circumstances a higher grade may be necessary, but not primarily for the purpose of improving gas mileage.

Another query: "If, as I read in a major daily paper, just one tire 10% under inflated cuts gas mileage by 10%, wouldn't all four tires under inflated by that amount cost 40%?"

Also not true.. That item was to have stated that if all four tires were under inflated by that amount, fuel economy would suffer by 10%. And, of course, these figures vary widely according to the vehicle and driving conditions. The fact does remain, however, that maintaining proper tire pressure conserves fuel. Here are other fuel economy suggestions from the Car Care Council:

* Keep your engine "in tune." Problems in the fuel, ignition or emission control systems hamper engine performance.
* Change oil and filter regularly. A good rule of thumb is every 3 months or every 3,000 miles.
* Drive conservatively. A "heavy" foot when accelerating from a stop or excessive braking wastes gas.
* Turn off your engine while at a drive through business or when waiting for your passenger.
* Open windows increase the drag on your vehicle, consuming more fuel. For better gas mileage roll the windows up and turn on the air conditioner. Better yet, use the vent.

In general, keeping one's vehicle well maintained goes hand-in-hand with fuel efficiency. A malfunction in the braking system, wheel misalignment, or a faulty transmission all can affect vehicle efficiency and your pocket book.
