Owning a car can be expensive. Maintenance and repairs are typically pretty costly. Then there is gas. If you drive a lot, you probably spend a lot of time at the gas station. The good news is that you can save fuel by focusing on these areas:
How long has it been since you checked your tire pressure? If your tires are below the recommended level, you are wasting money each time you fill up your tank. On average, a tire will lose around one pound per square inch (psi) every month. Less pressure in your tires means more friction/rolling resistance on the road. This makes your engine work harder to keep you moving. At the minimum, be sure to check your vehicle’s tire pressure monthly.
If your fuel cap is damaged or will not secure tightly, fix or replace it as soon as possible. Bad fuel caps result in the loss of millions of gallons of fuel each year from evaporation.
Your vehicle’s fuel economy decreases exponentially at higher speeds. Driving 65 on the highway instead of 75 could reduce your fuel consumption by as much as 10%! Your trip will not take much longer, and you will save fuel (and money) the whole way.
Air conditioning puts an increased load on your engine, which results in greater fuel usage. In addition, driving with your windows down at highway speeds increases drag and reduces fuel economy. When driving at 45 mph or lower, however, rolling down your windows will save you a little extra on gas.
Clean out the Clutter
It’s quite easy to end up with 50 to 100 pounds of extras in your trunk or storage compartment. The more weight your vehicle carries, the harder the engine has to work when accelerating. Make sure to clean out your trunk and cargo space regularly to keep that extra stuff from weighing you down.
Your engine has to breathe, and a dirty or clogged air filter can adversely affect performance and economy. Replacing an old, dirty air filter with a new one can improve your vehicle’s gas mileage by 5-10%
