How Often Should the Engine Lubrication System Be Cleaned?
2 Answers
Lubrication system does not require regular cleaning. Here is relevant information about the lubrication system: 1. System Introduction: The design of the lubrication system should be based on the characteristics and operating conditions of various mechanical equipment, and it always consists of several main components such as hydraulic pumps, oil tanks, filters, cooling devices, heating devices, sealing devices, buffer devices, safety devices, alarms, etc. 2. Lubrication Methods: In addition to the above classifications, lubrication methods can also be categorized based on the type of lubricant supplied, including oil lubrication (or thin oil lubrication), grease lubrication (or dry lubrication), as well as solid lubrication and gas lubrication.
I’ve noticed some drivers recommend cleaning the engine lubrication system every 30,000 to 50,000 kilometers, depending on driving habits. With decades of driving experience, I’ve found that if you frequently drive long distances on highways, you can extend the cleaning interval. However, frequent city driving with stop-and-go traffic leads to quicker engine sludge buildup, often requiring a cleaning every two to three years. The purpose of cleaning is to remove old oil residues and sludge, protecting pistons and bearings. Don’t assume you need a cleaning with every oil change—doing it too often is just a waste of money. Instead, clean when the dipstick shows darker oil or an unusual odor. After cleaning, the car accelerates more smoothly, and the engine’s lifespan can be extended by tens of thousands of kilometers. Of course, combining this with regular maintenance records makes for a smarter approach.
