“Many motorists don’t realize that fuel consumption is directly related to auto care and has a significant impact on how much gas you use,” said Rich White, executive director of the Car Care Council, which organizes National Car Care Month every April. The organization has just published a free 60-page car care guide, which includes some great maintenance tips for maximizing fuel economy. Here are their recommendations:
1. Get a Tune-Up
Regular tune-ups, maintenance and having clean air filters will help you burn less gas, pollute less and prevent car trouble down the line. A proper tune-up can boost gas mileage by 4 percent. Changing a dirty filter can improve efficiency by 10 percent and using the oil specified for your car saves up to 2 percent. If a tune-up turns up a faulty oxygen sensor, you’ll save up to 40 percent by replacing it.
2. Check Your Tires
Tires that are not properly inflated add rolling resistance that makes the engine work harder to move the vehicle. Tires can lose pressure due to seasonal temperature changes so pressure should be checked at least monthly, including the spare. (Check your manual for optimal pressure.) Do this regularly, and you’ll save 3.3 percent.
3. Get an A/C Inspection
The A/C system should be inspected annually, during which a technician checks pressures to test operation, refrigerant charge and outlet temperatures.
4. Watch Gas Caps and Fill-Ups
Approximately 17 percent of the vehicles on the road have loose, damaged or missing gas caps, causing 147 million gallons of gas to vaporize every year. Get yours checked, and when you fill up, avoid the urge to top off. It can release harmful vapors into the environment.
5. Questions to Ask Your Mechanic
Here’s what you need to ask your mechanic to make sure you’re getting maximum fuel economy:
• My car is getting lower gas mileage than normal. Does this mean there’s a problem?
• How often should my car have a tune-up?
• What components will you be inspecting and/or replacing as part of my tune-up?
• Are my tires properly inflated and is there enough tread for safe/effective performance?
6. Drive Green
Driving technique has a lot to do with your fuel economy. Avoid sudden starts and stops and go the speed limit. Jerky and aggressive driving decreases your miles per gallon (MPG) and increases wear and tear on your vehicle. Turn your car off instead of idling when you’ll be parked safely for more than 10 seconds. Also, drive wise and minimize unnecessary miles by doing errands in one trip, getting good directions and calling ahead.
7. Lighten the Load
Get your stuff out of your car and junk out of the trunk. This does not mean that you should not keep important emergency items such as a spare tire, flares and a first-aid kit. However, items that are not needed weigh the vehicle down—causing an increase in gas usage and unneeded wear and tear on a vehicle.
8. Keep Your Cool
Use the windows to help keep the car cool as much as possible when not on the highway. Park in the shade and use a reflective windshield shade when parked—it will take less gas to cool it off when you get back in.
