How Often Should You Replace Your Air Filter?

For better engine efficiency and increased gas mileage, you should replace the air filter on your car’s engine every 10,000 miles. Without the proper gasoline and air mixture, your engine will be forced to operate inefficiently. If the air filter is clogged, an inadequate amount of air is let in to the cylinder which makes it necessary for more fuel to be injected. Not only does this cause inefficiency, but your gas mileage decreases and you spend more at the pump.

Replacement Air Filter

As a rule, you should check the air filter every oil change or 3,000 miles. In that time it will have dirtied a bit, but it can usually be cleaned and used again. After about 10,000 miles it needs to be changed. However, if you live in a dusty region, it may be necessary to replace it sooner as the filter will get clogged faster.

Keeping on top of your air filter maintenance is good for your vehicle and ultimately better for your pocketbook. Your vehicle will run more efficiently with a clean or new air filter and you will reduce fuel costs. Get in the habit of checking your air filter every few months, cleaning it if necessary and replacing it about every third oil change.
