The Nissan Altima is a wonderfully efficient compact or midsize car. It consistently gets high ratings within its class for fuel economy from the EPA, which delivering adequate power to get from one side of town to the other. This four door sedan, when driven conservatively, really just sips fuel.

However, to get great gas mileage, there are certain maintenance procedures that must be taken. While the Altima was designed to be fairly maintenance free, basic maintenance is still important.

For example, the Nissan Altima’s air filter must be changed regularly. The paper elements of the filter can become clogged in as little as 10,000 miles, and certain environmental conditions can cause it to become clogged even sooner. Essentially, the filter is made of elements of a porous paper; the paper blocks all solid and liquid matter from finding its way into the engine, while the pores are large enough allow air to flow through without much interference. As the pores become clogged, however, the engine must work harder and harder to suck in the oxygen it needs, which reduces your power, essentially strangling your engine. If you want to upgrade your Nissan Altima’s air filter, you can purchase other styles, including reusable filters which, instead of paper, use a mesh with an oil to trap dirt and debris. These filters claim to offer significant increases in horsepower. Replacing the OEM filter is a rather simple task, and should only take a few minutes.
