Conservation Tip: Change your car’s air filterA few of you wrote in to also suggest another gas and pollution saving tip — changing your car’s air filter. Perhaps you’ve seen the accordion-like thing that the Jiffy Lube mechanic always shows to you when you are getting the oil changed.
Well, more often than not he is right. A blocked air filter can reduce mileage by 10%! (source:EPA) And every TerraPass member knows that a gallon of gas saved is 20 lbs of CO2 that doesn’t go into the air. You should change your air filter once every 12,000 miles. Why not do it at the same time you buy your TerraPass? You don’t even have to go to Jiffy Lube to change it. A new air filter costs about $20 (or about twice as much for a reusable version that will save you money in the long run). Edmunds has a great little video on how to change this yourself. All you need to fight climate change is two screwdrivers… Comments

If you want to be even more environmentally friendly, use a reusable air filter in your car, like the ones made by K&N. With regular cleaning and oiling (about as often as you change your air filter normally) they last for 50,000 miles or more. They also improve your engine's fuel economy and performance. Over the course of the lifetime of the filter, you'll also probably save 30-50% of the cost of buying the 10-12 regular disposable air filters that you would have purchased.

I always have a hard time making it to get my oil changed on time, not mention making sure that I have a clean air filter. I am going to have to make sure to have it cleaned for better fuel economy. Thanks for the info.
