![]() If you drive a great deal on unpaved roads, or through highway construction which can kick up a lot of dust and debris you may want to change your fuel filter more often. It’s often recommended that the filter should be changed every 2 years or 30,000 miles (whichever comes first), but that’s a general suggestion. HOW OFTEN SHOULD THE FUEL FILTER BE CHANGED? A fresh filter reduces contaminants and helps prevent damage to your engine and fuel system. Consistent, timely fuel filter maintenance is important to dependable drivability. These serious problems may have a simple, affordable solution: change the filter. When the Malfunction Indicator Lamp (MIL) or Check Engine Light comes on, it means the sensors have detected a problem. Many vehicles have sensors that monitor the fuel system. Sudden, unusual noises could be your vehicle’s way of letting you know something is wrong.ĭRIVE TOO LONG WITH A CLOGGED FUEL FILTER AND THE CHECK ENGINE LIGHT COULD COME ON electric fuel pumps can fail prematurely trying to push fuel through a dirty fuel filter. No one wants to suddenly stop in traffic! But that’s what could happen if you’re driving with a filter that’s passed its prime. A dirty fuel filter could prevent the engine from getting enough fuel.

Since this small component has a major responsibility, having it changed regularly should be a top priority.Engine repairs can be costly and could keep your vehicle in the shop for an extended period.

When to Replace the Fuel FilterĪlthough the owner’s manual will give you precise details, most manufacturers recommend changing the fuel filter every five years or 50,000 miles. Note: Even without these symptoms, you can perform a quick quality check on the fuel filter by removing and blowing into it. Also, if fuel efficiency starts to suffer or the engine behaves abnormally/erratically, you might need a new filter. In such cases, a quick cleaning can help, but you might also need a full replacement. Often, a weakened fuel filter will cause the engine to misfire. Whatever the case, foul odors mean you should have a professional take a look as soon as possible. It could mean other damaging issues are at play, as well. If your vehicle’s exhaust emits strong fumes, it could be a sign of a dirty fuel filter. In addition, if the car sputters when you drive at low speeds, the fuel filter likely has a minor blockage–a sign the need for replacement isn’t far ahead.

In many instances, the engine will start normally but will shut down when you try to stop. ![]() If you step on the gas to accelerate but the speed doesn’t change, you probably have a dirty fuel filter. Although a dirty fuel filter leads to ignition difficulty, a fully-clogged filter will fail completely, and the engine won’t start at all.

This dirty job makes filters especially vulnerable to debris buildup, and when yours becomes clogged, it helps to see the warning signs and attend to it as soon as possible. Regardless of the engine type (traditional or diesel), all vehicles have fuel filters that clean the oil before it reaches the engine.
