How to Select an Oil Filter

The right oil filter can make the difference between a fuel efficient, optimally operating vehicle and a sluggish vehicle that requires additional repairs. The oil filter is a surprisingly important component of vehicle maintenance. Choosing the best filter for your vehicle is one of the most important choices you can make for your vehicle. There are many choices available, including pleat size, normal or extended wear and the filtration capabilities of the filter.

• 1

  Check your vehicle's manual to determine the correct size of oil filter that you should install in your vehicle. Your manual will also tell you any other oil filter specifications that you should look out for, such as the type of filter or the media material that the filter is made from. When possible, choose an oil filter brand that matches the brand of your vehicle, as it will generally fit better.

  Inspect the filters at the store. Look for the filter with the most pleats. The more pleats a filter has the more dirt and contaminants it can collect from the oil. More pleats in the filter will also extend the life of the filter.

• 3

  Look for filters that have metal end caps. Some filters use cardboard end caps, which deteriorate much faster and can mean more filter replacements over time.

• 4

  Check that the filter has a tight anti-drainback barrier between the filter and the end caps. The best barriers have a tight rubber or silicone seal to prevent the oil from becoming contaminated with the same particles that were just filtered out.

• 5

  Inspect the pressure bypass valves. Metal pressure valves will last longer than plastic ones, and have less chance of breaking before the filter needs replacement.

• 6

  Look at how the filter installs into the vehicle. Filters that attach with nuts are easier to install and remove because they can be easily installed and removed with a ratchet set or wrench.

• 7

  Purchase a filter that can filter particles as small as three to 10 microns. This will increase the fuel efficiency of the vehicle and reduce wear on the engine and other components of the vehicle.
