Do You Need to Replace the Oil Filter When Changing Motorcycle Oil?
2 Answers
Replacing the oil filter is not mandatory when changing motorcycle oil. Oil Filter: The oil filter, also known as the oil filter element, does not need replacement if it uses a mesh screen. The oil filter is designed to remove impurities such as dust, metal particles, carbon deposits, and soot from the oil, thereby protecting the engine. Oil filters can be categorized into full-flow and bypass types. A full-flow filter is connected in series between the oil pump and the main oil passage, filtering all the lubricating oil entering the main passage. A bypass filter, on the other hand, is connected in parallel with the main oil passage and only filters a portion of the oil delivered by the pump. Cleaning and Replacement Intervals: The air filter should be cleaned or replaced based on the motorcycle model and road conditions. For scooters, it is recommended to clean the filter every 1,000 kilometers and replace it every 3,000 kilometers. If road conditions are poor, these intervals should be shorter. For standard motorcycles, cleaning is generally required every 5,000 kilometers, making maintenance more convenient.
I've been repairing my own motorcycle for many years, and every oil change comes with a filter replacement. The filter acts like the engine's scavenger, specifically capturing metal shavings, dirt, and other impurities in the oil. If you only change the oil without replacing the filter, the old filter is already clogged up, and the new oil gets contaminated as soon as it enters, significantly reducing its cleaning effectiveness. Over time, this accelerates engine wear, increases fuel consumption, and in more severe cases, can even cause overheating issues, leading to costly repairs. The filter itself isn't expensive—just a few dozen bucks online or at a shop—and it's simple to replace with just a wrench. Developing the habit of regular replacements makes your ride smoother and extends the engine's lifespan. All my riding buddies do the same—don't risk big problems to save small money. Safe riding is what truly matters.
