An Engine Oil Filter works just as the name describes; it filtrates the Motor oil that flows through the Engine. As Engine oil moves through and reduces friction between Engine components, the filter catches and traps impurities, so they won't make their way into your Engine. While the Engine is working to Maintain your Nissan, it burns Gas and eventually produces contaminants like dust, sludge, and other pollutants. If the Engine isn't able to filter and remove these pollutants because of a grimy or blocked Engine Oil Filter, they will continue to mix w/ your Motor oil and could ultimately cause damage and result in expensive repair costs. When your Engine Oil Filter is neglected, it can become clogged w/ all of this dust, dirt, and other debris. But what happens when an Engine Oil Filter is overloaded w/ this damaging Material? Your fuel efficiency and fluid pressure might start to diminish, and your car's exhaust system can become polluted and you may notice the smell of burning oil. So when should you replace your Engine Oil Filter? Your Engine Oil Filter replaCement should be done at the same time as your Motor oil. If you frequently take short trips or do tons of highway driving, you might have to get replaCements more often to Maintain your vehicle's Engine function. Is it possible to install your Nissan Engine Oil Filter From home? Maybe, but the process might involve some delicate maneuvering through the Engine to find the filter location. Consult your owner's Manual before replacing your Engine Oil Filter to avoid potential injury or ruining important Engine parts. If you are uncertain, it may be safer to get your filter changed by a licensed Nissan service location instead.
