8 Signs You Need To Change Your Fuel Filter

It’s crucial for the fluids in your car to remain clean—especially the fuel. If your fuel gets dirty, it can lead to problems with your engine, which can turn into expensive repairs.

Regularly maintaining and replacing your fuel filter can help keep your vehicle performing its best and save you from potentially costly repairs. Read on to learn about fuel filters, including what they do, how often they should be replaced, and signs you might need a new one.

What is the Purpose of a Fuel Filter?

The gas at the pump is stored in underground tanks, where it can collect rust, particles, and other impurities. When you pump fuel into your vehicle, these impurities come right along with it. The fuel filter is responsible for removing contaminants from the gas before they can reach the fuel injection system—and your engine.

What Causes a Clogged Fuel Filter?

Like other filters in your vehicle, the fuel filter slowly begins to collect and hold onto the particles it removes from your gas over time. These particles eventually clog the filter, impacting its effectiveness. That’s why it’s important to regularly service and replace your fuel filter.

When to Change the Fuel Filter

The maintenance interval for a fuel filter varies depending on your make, model, and year. Some vehicles may need a replacement every 20,000 miles, while others can go 150,000 miles on the same fuel filter. If you have a newer vehicle, you may even have a lifetime fuel filter that doesn’t need routine maintenance and replacement.

Always check your manufacturer’s recommended maintenance schedule for details on your specific vehicle.

What Are the Symptoms of a Dirty Fuel Filter?

Several factors can affect the lifespan of your filter—like filter quality, vehicle age, and driving habits—so you may need to replace the filter sooner than expected. Clean vs. dirty fuel filters perform differently, and your vehicle will likely let you know when it’s struggling with a clogged filter.

Here are eight clogged fuel filter symptoms that could mean it’s time to schedule an appointment for a replacement.

1. Difficulty Starting Your Car

When you turn the ignition, the fuel pump sends fuel from the tank to the engine. If your fuel filter is clogged, it can restrict this flow and make it difficult for the engine to start. You may notice the engine cranking longer than usual before finally turning over.

2. Sluggish Acceleration

If your car struggles to accelerate, especially uphill or when carrying heavy loads, it could be a sign of a clogged filter. During acceleration, a dirty fuel filter can restrict gas flow, causing the engine to hesitate or stumble as it struggles to get the fuel needed for increased power and speed.

3. Rough Idling

Since a dirty filter can limit the amount of fuel reaching your engine, you may experience rough idling. Most vehicles have some level of vibration at a stop, but more intense vibrations or lurching when accelerating can indicate a clogged fuel filter.

4. Engine Stalling

If the fuel filter is severely clogged, the insufficient fuel supply may cause your engine to stall out completely. If your car is stalling frequently, especially at an idle, you should stop by your local Firestone Complete Auto Care to have the fuel filter checked.

5. Poor Gas Mileage

An engine running with a clogged fuel filter can burn more fuel than usual in an attempt to maintain performance. A clogged fuel filter is just one reason you might have low gas mileage, so it’s recommended you visit professionals for diagnostics.

6. Strong Gas Odors

In some cases, a clogged fuel filter can cause unburnt fuel to escape through the exhaust system, leaving your car's cabin smelling like gas.

A strong gas odor could also indicate other issues, like fuel leaks and fuel injector issues. The pros at Firestone Complete Auto Care can help find the root of and fix the issue, whether it’s the fuel filter or not.

7. Fuel Pump Noise

The fuel pump works to maintain proper pressure in the fuel lines. When the fuel filter is clogged, the pump has to work harder to push gas through. The extra effort can cause the pump to produce a strange noise that may be heard inside the vehicle.

8. Check Engine Light Comes On

As fuel struggles to flow through the clogged filter, it can cause low fuel pressure. This low fuel pressure may eventually trigger the check engine light. The technicians at Firestone Complete Auto Care have the necessary tools to read the diagnostic trouble code, find the problem, and fix it.

Bad Fuel Filter Symptoms - Jiffy Lube

DRIVE TOO LONG WITH A CLOGGED FUEL FILTER AND THE CHECK ENGINE LIGHT COULD COME ON

Many vehicles have sensors that monitor the fuel system. When the Malfunction Indicator Lamp (MIL) or Check Engine Light comes on, it means the sensors have detected a problem.

These serious problems may have a simple, affordable solution: change the filter. Consistent, timely fuel filter maintenance is important to dependable drivability. A fresh filter reduces contaminants and helps prevent damage to your engine and fuel system.

HOW OFTEN SHOULD THE FUEL FILTER BE CHANGED?

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. 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. You should consult your vehicle owner’s manual for the recommended interval for your specific vehicle.

Don’t skip a scheduled maintenance check, but don’t hesitate to have a professional look at your vehicle between appointments if you experience any of the five bad fuel filter symptoms listed, either. Visit one of the 2,000 Jiffy Lube locations all across North America and a trained Jiffy Lube technician will:

Ask about your driving style to determine the impact it may have on your vehicle’s fuel system
Describe the bad fuel filter symptoms and ask which you may be experiencing
Remove the used fuel filter
Replace the used fuel filter with a new filter that meets or exceeds the manufacturer’s recommendation

DON’T NEGLECT YOUR VEHICLE’S OTHER FILTERS

The fuel filter isn’t the only filter that works hard to ensure top vehicle performance. When you visit Jiffy Lube, the technician will also visually inspect the:

Engine air filter. Just as the fuel filter helps captures debris that’s in the fuel, the engine air filter protects the engine from airborne contaminants.
Transmission filter. Your automatic transmission relies on the filter to prevent dirt and debris from getting into the hydraulic system.
Cabin air filter. The cabin is where you and your passengers sit, and the cabin air filter helps remove dust, pollen and mold so you all can breathe easier.

The Jiffy Lube technician will let you know if a replacement of any kind is recommended, but won’t do any work without your consent.
