The gas mileage, or the number of miles you can drive on each gallon of gas, is an important number for your car. The higher your gas mileage is, the less you’ll spend on gas and the lower your carbon footprint will be. If you’ve noticed that you’re suddenly making more trips to the gas station, find the reason for this decrease in mileage and address it quickly with the appropriate auto repair. Consult the guide below to find out why your gas mileage has decreased. 

What Are the Causes Behind Poor Gas Mileage?

1. Failing Fuel Injectors

The fuel injectors are responsible for putting fuel into the engine, so they control the amount of gas that you use. If they are leaking, then less fuel will get into your engine, and it won’t run as efficiently as it should. You may notice that you also have trouble starting your car, and your engine isn’t reaching its full RPM. Take it in for auto repair, and your mechanic will replace them.

2. Incorrect Tire Pressure

Incorrect tire pressure will reduce your mileage. If your pressure is too low, for example, then your tires will have too much surface area on the road. This forces your engine to work harder, much like trying to ride a bike with a flat tire. Check your tire pressure with a gauge at least once a month and fill it if needed. Your tire sidewall should indicate the recommended PSI range.

3. Poor Air Filters & Oxygen Sensors

The oxygen sensors are responsible for mixing air and fuel, and when they malfunction, they may create the wrong balance. This, along with a clogged air filter, can cause inefficiency. The air filters should be replaced on the schedule recommended in your vehicle owner’s manual. A mechanic can check your oxygen sensors during an auto repair appointment.
