If your answer is that you thought the warning light was just a permanent fixture on your dash, maybe it\u2019s time to do some serious soul-searching. It\u2019s easy enough to put off changing your oil and<\/span> <strong><a href=\"https:\/\/www.napaonline.com\/en\/p\/FIL7202?cid=social_blog_042017_OilFilter\" target=\"_blank\" rel=\"noopener noreferrer\">oil filter<\/a><\/strong><span style=\"color: #000000;\">, but the damage caused by this negligence can be swift or a long time coming \u2014 it will arrive one way or another, though. Knowing how an oil filter works and what it does for your engine might help you gain a better appreciation for the little things that play a big role in keeping your car humming.<\/span><\/p>\n<h3 dir=\"ltr\"><strong>Inner Turmoil<\/strong><\/h3>\n<p dir=\"ltr\"><span style=\"color: #000000;\">The importance of a properly oiled engine cannot be understated. With all the rapidly moving parts working in such precise proximity to one another, oil helps remove heat and ease movement to reduce friction. Too little, too much, incorrectly pressurized or contaminated oil spells quick and expensive trouble for your engine. Oil filters play an integral role in maintaining proper oil quality and supply. Over time, oil takes on tiny particulate matter and minuscule metal shavings from the combustion process. If unchecked, these particles can accumulate and damage the pump, engine bearings and any surface the oil passes under pressure, such as cylinder walls. They can also clog the filter, which puts you in danger of decreased oil pressure and can quickly cause severe engine damage.<\/span><\/p>\n<h3 dir=\"ltr\"><strong>Toiling <\/strong><strong>Away<\/strong><\/h3>\n<p dir=\"ltr\"><span style=\"color: #000000;\">The oil filter works to remove contaminants from engine oil, extending the life of the engine and maintaining high oil quality, which naturally degrades over time. The oil pump sends used oil through a filter element, removing the particles and allowing the oil to pass through. The freshly strained oil is then taken back up to the engine for lubrication. There are<\/span> <strong><a href=\"http:\/\/knowhow.napaonline.com\/whats-best-oil-filter-oil-youre-using\/\" target=\"_blank\" rel=\"noopener noreferrer\">different makes and sizes of oil filters<\/a><\/strong><span style=\"color: #000000;\">, and it\u2019s important to consult your owner\u2019s manual and verify that the replacement will fit. An ill-fitting filter can cause leaks and damage the threads on the engine, which require more intensive repairs. If the oil filter is too big or too loose, it can come off entirely, making a big mess and bigger internal problems.<\/span><\/p>\n<h3 dir=\"ltr\"><strong>Spoil<\/strong><strong>ed Components<\/strong><\/h3>\n<p dir=\"ltr\"><span style=\"color: #000000;\">Spin-on oil filters are pretty straightforward, but not all are created equal. They consist of a metal housing, a base plate that matches up to the engine, a sealing gasket to help insure fit and guard against leaks and a filter element. Most oil filters today also come with a bypass valve as a backup in case of a clog. The base plate has one large hole in the middle and several smaller ones surrounding it. The filter element runs lengthwise in a circle, between the big and smaller holes. Oil is forced through the outside holes through the filter, and the engine picks it back up through the main chamber. The bypass valve exists on the boundary between used and filtered oil and opens when the pressure rises enough to indicate a problem with flow. These are the main components, but manufacturers deploy them differently to be more effective or sometimes to cut costs. A lot rides on the materials and internal design; generally, you get what you pay for.<\/span><\/p>\n<p dir=\"ltr\"><span style=\"color: #000000;\">Hopefully, this knowledge inspires you to change that oil filter as recommended. Just remember, it\u2019s a big job for an unassuming object, so don\u2019t skimp on quality.<\/span><\/p>\n<p dir=\"ltr\"><span style=\"color: #000000;\">For more information on choosing an oil filter, chat with a knowledgeable expert at your local<\/span> <strong><a href=\"https:\/\/www.napaonline.com\/en\/store-locator\" target=\"_blank\" rel=\"noopener noreferrer\">NAPA AUTO PARTS store<\/a><\/strong><span style=\"color: #000000;\">.<\/span><\/p>\n<p><em><span style=\"color: #000000;\">Photo Credit:<\/span> <a href=\"https:\/\/www.flickr.com\/photos\/razor512\/2652562115\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Oil-Filter<\/strong><\/a>\u00a0<span style=\"color: #000000;\">by<\/span> <a href=\"https:\/\/www.flickr.com\/photos\/razor512\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Razor512<\/strong><\/a>\u00a0<a href=\"https:\/\/creativecommons.org\/licenses\/by\/2.0\/legalcode\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>(CC BY 2.0)<\/strong><\/a><span style=\"color: #000000;\">.<\/span><\/em><\/p>\n<p><span style=\"color: #000000;\"><i>This article has been reproduced with the permission of the copyright holder, National Automotive Parts Association.
