Replacing your dirty air filter saves your gas mileage?.

According to fueleconomy.gov driving with an excessively dirty or clogged air filter can reduce your vehicle’s gas mileage by up to 10%. In terms of dollars, that’s the equivalent of adding close to $.30 to each gallon of gas you buy!
Edmonds.com recommends that you change your air filter at least once per year. But how do you know when your car’s air filter is dirty enough so that it should be replaced?
Here’s a simple way to know that your air filter has become so clogged that it has become a detriment to your fuel economy: Remove the air filter from its casing and shine a flashlight on it. If light (or most of the light) is able to get through, your air filter is fine for the time being. However, if most of the light is unable to get through, it’s time for you to replace the filter.
More than likely, the air filter that you would need is readily available at most auto parts stores and you should be able to replace the filter on your own. All said and done, it should take less than 15 minutes to check and, if necessary, replace a clogged air filter.
Sounds to me that 15 minutes and $20 bucks (for the new filter) is time and money well spent if it means your not tacking $.30 extra cents on to each gallon of gas you buy!
