In researching an article for another publication, I gathered a list of tips to save fuel. Many of them I was already aware of but some were new to me; perhaps they'll help you, and I've added more.
Maintenance
The most basic and very best way to increase your fuel ratio is to keep your automobile well maintained. Tune-ups should be performed on a systematic basis and the manufacturer normally has a recommendation on the frequency.
In addition to tune-ups, the air filter should be kept clean. That's an easy one; even I can change an air filter!
The vehicle's chassis and suspension should be periodically inspected for misalignment. Anything out of line (wheels, axles), bad shocks or broken springs create a drag on the engine and reduce the fuel economy plus can also be unsafe.
Fuel filters should also be examined against leaks.
Tires
Tire pressure affects fuel consumption. Tires should be inflated to the maximum limit and checked frequently to make certain the pressure is maintained. That's not always the most comfortable ride but it is the most economic.
Tires should also be balanced on a routine basis.
Radial tires are recognized as the best for fuel saving.
Snow tires, if used, should be removed when they're not needed. Driving on deep treads decreases fuel economy.
Octane
There's no evidence to support the theory that your car will receive better mileage if you use premium gasoline. Unless the manual for the vehicle specifically states you should use higher-octane fuel, stick with the lower priced blends.
Weight
Remove everything from your vehicle that is not essential to your day-to-day operation. This includes extra tires, tools and even bowling balls. Not only do you want a clean and clear space in the event you have passengers or parcels, but carrying an extra 5-200 pounds can cost you as much as 1-3 mpg.
If you operate in a cold climate, always remove the icicles that form under your car. They add weight and drag; a swift kick or two will increase the gas mileage.
Heating and air conditioning
