What are the effects of not changing motorcycle engine oil?
2 Answers
Not changing motorcycle engine oil mainly has the following effects: Damage to the engine: If the engine oil is not changed for a long time, once the oil deteriorates and its performance declines, the lubrication performance of the bearings and the lubrication and cooling functions of mechanical transmission components will be lost, thereby damaging the engine. Reduction in engine lifespan: During the use of engine oil, it minimizes friction between gears and cleans small debris generated by friction. At the same time, the oil in contact with air also undergoes oxidation. If the oil is not changed for a long time, the lubrication effect of the oil will decrease, and small debris inside the engine cannot be expelled with the oil discharge. This will cause scoring on the friction parts inside the engine, affecting the engine's power output and severely reducing its service life.
I've been riding motorcycles for over a decade and have seen many people neglect oil changes, which leads to numerous troubles. Engine oil is like blood, responsible for lubricating internal engine components and reducing friction and wear. If not changed, the oil deteriorates, accumulating metal particles and acids, which degrades its lubricating properties. This can trigger a series of issues: increased wear on cylinder walls and piston rings, reduced power output, higher fuel consumption, and even the risk of overheating and stalling. Over time, repair costs skyrocket, potentially requiring expensive engine overhauls or part replacements. I always recommend following the manual's advice—changing the oil every 3,000 to 5,000 kilometers or every six months. Simple maintenance like this extends your bike's lifespan, saving both hassle and money.
