What\u2019s really going on here? Are oil filters just another money-making add-on or a critical part of every oil change?<\/p>\n<h5><strong>How Engine Oil Filters Work<\/strong><\/h5>\n<p>As suggested, oil filters filter oil. New, clean oil immediately starts to pick up metal flakes and old deposits from oil passageways. Over time, as the oil completes many thousands of circuits through the engine, it starts to oxidize, and other reactions generate particles in the oil.<\/p>\n<p>Given that some passageways in your engine are exceptionally small \u2014 some main bearing clearances are just 0.002,\u201d or slightly thicker than a human hair \u2014 you don\u2019t want stray particles to get lodged in there. The oil filter captures these particulates and metal, preventing them from circulating through the engine and causing damage. But how much debris can the oil filter collect?<\/p>\n<p>Unfortunately, that question isn\u2019t an easy one to answer. Most filter companies express filter efficiency as a percentage of particles of a certain size that the filter is able to capture. However, few filters display this filter debris capacity, and some products don\u2019t display any such information.<\/p>\n<h5><strong>When Is the Right Time for Changing an Oil Filter?<\/strong><\/h5>\n<p>All oil filters have limited debris capacity and then become useless. Once an oil filter reaches capacity, excess pressure opens the bypass valve. This allows unfiltered oil into the engine lubrication system, where particles can wreak havoc on bearings, rings and journals, or get stuck in chain tensioners or lifters. Unfortunately, without some sort of mechanical clairvoyance, there\u2019s no practical way to tell if the oil filter is stuffed. Changing an oil filter is the only way to prevent problems from occurring.<\/p>\n<p>It\u2019s a good idea to change an oil filter at the manufacturer\u2019s recommended interval. Check your owner\u2019s manual or maintenance manual for specifics.<\/p>\n<p>In general, it\u2019s better to be safe than sorry when it comes to oil filter capacity.<\/p>\n<p>Check out all the\u00a0<a href=\"https:\/\/www.napaonline.com\/en\/c\/ignition-parts-filters\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>ignition parts &amp; filters<\/strong>\u00a0<\/a><wbr \/>available on\u00a0<strong><a title=\"Click to open in a new window or tab https:\/\/www.napaonline.com\/\" href=\"https:\/\/www.napaonline.com\/\" target=\"_blank\" rel=\"noopener\">NAPA Online<\/a><\/strong>\u00a0or trust one of their 17,000\u00a0<strong><a title=\"Click to open in a new window or tab http:\/\/www.napaautocare.com\/store-finder.aspx\" href=\"http:\/\/www.napaautocare.com\/store-finder.aspx\" target=\"_blank\" rel=\"noopener\">NAPA AutoCare locations<\/a><\/strong>\u00a0for routine maintenance and repairs.
