What Causes Poor Fuel Efficiency in My Vehicle?

If you’ve noticed that your car isn’t getting as many miles per gallon as it used to, there could be a problem. Poor fuel efficiency can happen for many reasons, but it often means your car isn’t running as smoothly as it should.

A clogged air filter can make the engine work harder, using more gas than necessary. Low tire pressure can also waste fuel by creating extra resistance while driving. Problems with the fuel system, like dirty fuel injectors, can keep the engine from burning gas efficiently. Even a bad oxygen sensor can throw off the fuel mixture, causing your car to use more gas than it needs. Driving habits also play a role—quick acceleration and hard braking can use up fuel faster than steady driving.

If your car is burning more gas than usual, it’s a good idea to get it checked out. Fixing small issues now can save you money at the pump and help your car run better.
