Car Fuel Filter Replacement Guide
Every BMW with a gasoline engine has a fuel filter in the fuel line somewhere between the fuel tank and the combustion chamber in the engine.
What Does a Car Fuel Filter Do?
The fuel filter, just like the engine air filter, is engineered to keep debris from your fuel tank. The fuel is perfectly clean when it’s at the refinery. But it can be stored in tanker trucks, tanks near the refinery, and gas station tanks that might have rust, dirt, or contaminants in them. That’s why you need a fuel filter. We would rather you not have rust getting into the combustion chamber of your beautiful BMW!
You’ll see these signs of a clogged fuel filter, indicating it’s time for car fuel filter replacement:
- Trouble starting your vehicle
- Vehicle sputtering or even stopping
- Reduced gas mileage
- Poor acceleration
- Drop in fuel pressure
- Less engine power and less horsepower
- Complete breakdown
Replacing your old fuel filter with a fresh one gives your BMW an immediate boost with an increase in fuel economy, more power, and no problems starting or accelerating.
Car Fuel Filter Replacement Schedule
Consult your owner’s manual for the correct car fuel filter replacement schedule. In general, expect to change your fuel filter every 12,000 to 30,000 miles, or every one to two years, depending on your model.
Engine Air Filter
Next, we talk about the engine air filter, an important yet sometimes forgotten part of vehicle maintenance for Hamilton Township BMW owners. All internal combustion engines need engine air filters for proper operation.
What Does an Engine Air Filter Do?
An engine air filter is designed to keep dirt, dust, sand, and other contaminants from getting inside the combustion chamber. This filter can get dirty and clogged over time, restricting airflow and reducing your BMW’s performance.
You should replace your engine air filter if your vehicle experiences:
- Sluggish acceleration
- Misfiring spark plugs
- Black smoke in the exhaust
- Service Engine light comes on
- Worse fuel economy on Mount Laurel streets
A new engine air filter improves performance, acceleration, and gas mileage, which you’ll see right away! Now we’ve answered, “What does an engine air filter do?” Next, we’ll talk about when to replace the engine air filter.
Engine Air Filter Replacement Schedule
Read your owner’s manual to see the exact engine air filter replacement schedule. In general, you must replace the engine air filter once every 12,000 to 40,000 miles. Lastly, we’ll answer, “What is a cabin filter in a car?”
Cabin Air Filter
The cabin air filter works with your vehicle’s HVAC system for the air that goes into the cabin of your BMW.
What Is a Cabin Filter in a Car?
The cabin filter in your car usually sits behind the dashboard as part of your car’s air conditioning system. It filters the air before it reaches the cabin, preventing dust, pollen, smoke, and other contaminants from getting into the cabin. You and your passengers breathe higher-quality air as you drive in Evesham Township and beyond.
The signs of a clogged cabin air filter may be:
- Weak airflow through the A/C vents
- Smelly air
- Increase in sneezing or allergies from dust and pollen
A fresh cabin air filter should immediately bring fresher air to you and your passengers.
Cabin Air Filter Replacement Schedule
Just like the other filters, your owner’s manual is the authority on your cabin air filter replacement interval. We recommend a new cabin filter every 12,000 to 30,000 miles, or every one or two years. Consider replacing the engine and cabin air filters sooner if you frequently drive in dusty conditions.
