Top Indicators That You Have A Dirty Car Air Filter

Car filters clean the air that enters the engine, and if your filters are unclean, you may jeopardize the engine’s operation. There are several indicators that something is wrong with the engine and filters. Here are a few things to keep an eye out for as you drive down the road.

Fuel Efficiency Has Dropped

You should keep note of how many miles you get per gallon of petrol, and if you observe your vehicle’s fuel economy dropping, you should investigate why. The filters are simple for mechanics to inspect and replace. They have the potential to reduce fuel efficiency, thus they must be monitored.

Misfiring Engine

If your engine isn’t getting enough air, it might be due to clogged filters. The engine may misfire or fail to start correctly, and failing to change the filters may result in far greater problems down the line. 

The Check Engine Light Is On

There are several warning lights that may illuminate your car, and it is critical to pay close attention to any of them, particularly the check engine light. Don’t be alarmed straight immediately because the light might turn on for a variety of reasons. However, you should have it checked out as soon as possible. Filters are simple to replace, and if that’s all there is to it, you may breathe a sigh of relief.

Power Reduction

You know how your car feels when you accelerate, and if you don’t have as much power as you used to, it might be because the air is straining to get through the filters, which are unclean and in need of replacement.
