Fuel Efficiency Not What it Used to Be? Check Out These Culprits

You may not be all that concerned about how smooth your car rides so long as it gets you there. You may not be all that worried about how much pollution your car is creating since it doesn’t have an immediate impact on you. But the one thing that almost every vehicle owner places as a top priority is fuel efficiency. Getting good gas mileage has a big impact on your bottom line. If you aren’t getting good gas mileage, you’ll end up spending way more than you want on gas.

Your gas mileage may start out great, but you may notice that it declines over time. If you aren’t getting the same gas mileage that you used to, there may be a number of reasons why. Here are a few common culprits:

Catalytic Converter

The catalytic converter is an essential component of your exhaust system. It is responsible for converting toxic pollutants into less harmful chemicals. Not only is this better for the environment, but it is also better for your car and your gas mileage.

A properly functioning exhaust system reduces the strain on your engine, and that lowers your gas mileage. Your exhaust is the first thing to inspect if you see your gas mileage creeping. Have your 3 way catalytic converter inspected, as well as your muffler, your filter, and other components.

Fuel Injection

Of course, your fuel injection system also plays a big role in your fuel efficiency. A drop in gas mileage could indicate a dirty fuel filter or a problem with the fuel injection system. Ideally, you should be getting the system serviced along with your other routine maintenance, which will prevent problems from forming.

You may also have some success in keeping your fuel injection system clean by adding some treatments to it. You can find these at auto parts shops, and they include ingredients that clear the system of pollutants.


Your tires need to be balanced and must have the right pressure and tread depth in order to optimize your fuel efficiency. If any of those elements is off, your tires will put drag on your car and cause you to use up more gas. Get your tires rotated and balanced when you bring your car in for an oil change, and make sure you keep an eye on the alignment. Check your tread depth regularly, and keep your tires inflated at the right pressure. Just taking these simple steps will be enough to save you thousands on gas over time.

By maximizing your fuel efficiency, you will not only save money, but you will also do your part for the environment by reducing your demand for natural resources. Keeping your car in the right shape will improve your fuel efficiency and extend the life of your car. Taking these steps is a win any way you look at the situation.
