You may already know that the best filters for eliminating contaminants from the motor oil in your engine are made by GM and factory-direct. But how do oil filters work? It's straightforward. Engine oil gets pushed back and forth through them by your motor oil pump. Oil passes through surface fibers that capture dirt, debris, and other pollutants. This keeps waste from accumulating in the engine. The results are not only cleaner oil and fewer engine pollutants, but also the best engine performance you can get. However, even high-quality OEM oil filters like those GM makes wear out eventually. They usually either get clogged or simply degrade. That can mean sludge build-up in your engine, leading to oil pump, bearing, and engine wear. Plenty of other auto parts that work with your engine can be negatively affected, too. It's a good idea to change your oil filter when you see these problems, but most automakers suggest doing it at every oil change: in other words, every few months or few thousand miles. If you're asking, "what oil filter do I need," be careful. Many filters can look the same; however, they vary by both thread size and gasket size. Using the wrong filter for your GM vehicle can cause oil leaks, or the filter could simply detach. The latter can result in some serious engine damage. Luckily, you can consult your owner's manual on what oil filters to use and when. Either way, you'll soon discover that a genuine GM oil filter will be your best bet.
