How to Improve Old Car Gas Mileage

Even older classic cars with large engines can benefit from gas-savings techniques.

Many owners of newer vehicles enjoy the benefits of great gas mileage. This is because newer models are often equipped with more efficient engines and lighter bodies that utilize aerodynamic styling. Older cars, on the other hand, are often powered by large engines that tend to guzzle gas in order to propel the car's heavy frame down the road. Of course, owning an older vehicle doesn't mean you have to surrender to horrible gas mileage. There are ways to make your classic vehicle more fuel-friendly.

Instructions

1. Schedule regular maintenance. It is particularly important that you care for your car's engine, making sure it runs smoothly. One of the best ways to ensure the engine is working properly is to check the oil regularly and replace it every 3,000 miles. If your car has high mileage, you can purchase oil specifically designed for high-mileage engines.

2. Replace the car's air filter/cleaner. A filter that is dirty or clogged with debris will further inhibit any car's ability to get better gas mileage. If your car is old enough to have a carburetor, it will have an air cleaner located on top of the engine. A new filter will enable the vehicle's engine to breathe, which enhances engine performance and efficiency.

3. Measure the air pressure in your old car's tires. If you don't have an air pressure gauge, you can purchase an inexpensive one at any automotive supply store. Tires that are low in pressure increase the level of friction on the road, lowering gas mileage. Add air as needed to any tires that are low.

4. Remove extra weight. Because chances are that your car is already heavier than many newer vehicles on the road, any additional pounds will only compound the problem. Check the car's trunk for unneeded cargo and remove anything you don't want. Depending on the make and model of the car, you may even consider replacing a full-size spare tire with a smaller, lighter donut spare. Of course, check with your mechanic to make sure this would work for your specific car.

5. Modify how you drive the vehicle. The best way to drive in order to achieve better gas mileage is to take it slow. Try not to go over 55 mph and pay attention to how to stop and start out. When stopping, press the brakes gradually and anticipate the stop in advance. When starting out, do it gradually as well, accelerating at a steady pace.
