Oil filters trap dirt, sludge, metal particles, and other impurities in your motor oil. That's to keep the oil as clean and pure as possible, which allows it to do its best job of lubricating the inner parts of your engine. Without a good filter, the gunk could damage internal engine parts, raise engine operating temperatures through increased friction and shorten the life of your engine. Most people change their oil according to their vehicle's manufacturer recommendations, found in the owner's manual. That can be 5,000 miles, 7,500 miles, or some other number. You'll find people who are fanatics about changing their oil every 3,000 miles — to make sure it's the cleanest, purest, and best it can be. But a lot of owners and mechanics —many of them the same people who would never go past 3,000 miles per oil change — also would never dream of doing an oil change without also changing the filter. Their reasoning: Why pass brand-new, clean oil through a filter that's already carrying gunk from the old, dirty oil?
