How Often Should the Engine Filter Be Replaced?
2 Answers
Replace every 40,000 kilometers. More details are as follows: 1. Definition: The gasoline filter, also known as the fuel filter, primarily functions to filter out impurities from gasoline. It comes in two types: carburetor-style and fuel injection-style. If the fuel quality is poor and contains many impurities, it can damage components such as the fuel injectors, fuel pump, and fuel lines in the engine, thereby affecting the normal operation of the fuel system. 2. Function: The gasoline filter can remove solid impurities like iron oxide and dust or water contained in the gasoline. This not only reduces the likelihood of injector clogging by impurities but also ensures the quality of gasoline entering the fuel system, optimizing engine performance and providing the best protection for the engine. However, the gasoline filter is a consumable part of the car and needs to be replaced after prolonged use.
Changing the engine air filter is something I have a lot of experience with, as I frequently drive long distances for business trips. The city has a lot of dust, so the filter gets dirty quickly. Generally, it's recommended to replace it every 12,000 kilometers or once a year. However, in my actual usage, if I often drive through construction sites or encounter sandy weather, I shorten the interval to checking it every 8,000 kilometers. Delaying the replacement can affect the engine's air intake, leading to a fuel consumption increase of over 10%, and even damage the cylinders, resulting in shockingly high repair costs. I've developed a habit of pulling out the air filter during every car maintenance to check it. If it's blackened, I replace it immediately. This method is simple and effective, extending the engine's lifespan and saving a lot on repair expenses. Remember, don't just rely on the mileage; adjust the frequency based on actual road conditions.
