Filter Replacement

Let’s talk about the proper time to replace your vehicle’s filters.
Air Filter: It is extremely important to keep the air filter clean for the engine to run efficiently and maintain good fuel economy. The air filter should be inspected at every oil change. Remove the filter and determine how much dirt is embedded in it. The best way to do this is to take a flashlight and shine it through the filter and see if the light shines through to the opposite side. Also, tap the filter on the ground to see how much dust and dirt comes out. If there is no light shining through and there is an excessive amount of particles coming out, then it is definitely time for a new filter.
Fuel Filters: Always remember that a restricted fuel filter is the number one cause for fuel pump failures. Most fuel pumps are located in the gas tank and can be expensive to replace. Many newer model vehicles also have the fuel filter in the tank. These particular filters do not require replacement. (Check the owner’s manual to see what type of fuel filter your vehicle contains.) Most manufacturers recommend replacement of external fuel filters every 30,000 miles. My experience tells me that this may be too long. I’ve seen fuel filters become restricted at 10,000 miles. This all depends on fuel quality. Always try and get fuel at the same gas station. After 20,000 miles have your mechanic check the filter for restriction. If it is restricted, then it is time to change gas stations. (It has been suggested not to get fuel when you see gas being delivered into the station. This possibly stirs up dirt that will get into your gas tank.) Your mechanic should know the best stations for clean fuel in your area. Also, the fuel filter may be restricted if the vehicle is not shifting properly or there is hesitation.
Cabin Filters: Cabin filters are more common in newer model vehicles. They work to filter the air coming into the vehicle. Once again, check the owner’s manual to determine if your vehicle has a cabin filter and what the recommended replacement intervals are. If the vehicle has this filter, keep in mind the air quality in the area that you live. If driven in big city, high construction and high pollen areas then they will need to be checked more frequently. A good indicator that a cabin filter needs to be replaced is when there is low air flow from the vents.
