Keep an eye out for differences in prices for the same octane level at different gas stations. The difference in price can be significant. Gas stations within a block of each other or even across the street can offer several cents difference for the price per gallon, even when they are the same gas company. Utilize the gas station with the better rate; assuming the location of the cheaper gas station is convenient.

        A tip for vehicles requiring the highest octane fuel, 93 octane; is that many gas stations offer a $.05 reduction in price on specific days. Note the days of the discounts for the specific gas stations, then fill up your car only on those days. If you do not have enough fuel to last until the day of the special, then add enough fuel to last until the day of the special, then fill the entire tank on that day. Keep in mind, most cars do not require the higher octane. Use the grade indicated in your owner's manual. Using the lower octane is much cheaper and better for your engine allowing it to work less.

        Ensure the tire pressure is at the correct level for your tires by checking about every month. Low tire pressure will result in decreased fuel efficiency and greater wear on your tires and suspension. Use a tire pressure gauge purchased at a store as opposed to a gas station's which may be less accurate due to mishandling. Keep in mind, a cause for low tire pressure is that the air naturally slowly leaks through the tire treads, the valve stem, and the tire rim. If you are filling the tire often, then you probably have a slow leak. Have a mechanic repair the tire.

        Other suggestions for improving your fuel efficiency, save money, and allow your engine to perform better for a longer period of time are: ensuring the car is tuned properly, ensure the tires are balances and aligned properly, driving slower, avoiding fast starts and quick stops, shutting off the engine if you plan to idle for several minutes (for example, at a train track), and removing any unnecessary racks or storage bins mounted on the roof.

        A problem with your tires and engine can be easily determined if your fuel economy drops causing you to fill the tank more frequently. Check your miles per gallon every time you fill the tank. Take the miles driven since the last fill up then divide it by the gallons purchases to determine the miles per gallon. Continually keep track of the information to gauge any problems or patterns with your fuel economy.

        Use your car less. Instead of driving for short trips, walk, ride a bike, or use public transportation. The result will be less wear and tear on your vehicle and reduced gas expenses, which will save you money. Not to mention the health benefits which provides a great means for exercise.
