There are a few potential factors that can affect fuel economy. Firstly, check your tire pressure. Under-inflated tires can cause added resistance and a decrease in fuel efficiency. Additionally, a dirty air filter can also contribute to lower gas mileage. Be sure to change it regularly to keep your engine running at its best. Other factors that can affect fuel economy include driving habits, road conditions, and maintenance schedule.

One common culprit for lower fuel economy is a faulty oxygen sensor. This sensor monitors the amount of oxygen in your exhaust and adjusts the fuel-to-air ratio accordingly. A malfunctioning sensor can cause your engine to use more fuel than necessary. If you suspect this may be the issue, have a mechanic check it out as soon as possible.

Another possibility is a clogged fuel filter. This component helps keep dirt and debris out of your engine and is essential for proper fuel flow. Over time, the filter can become clogged and restrict fuel flow, reducing your gas mileage. If you have not replaced your fuel filter in a while, it may be time to do so.
