Symptoms of Using Low-Quality Engine Oil in Motorcycles?
4 Answers
Symptoms of using low-quality engine oil in motorcycles include the following: Initial stage after using low-quality engine oil: Initially, the motorcycle sounds normal, but after running about 300 kilometers, the valve noise becomes noticeably louder. Engine oil consumption begins: Originally, the motorcycle did not consume engine oil. However, after using that oil, the oil level inexplicably starts to decrease. Clutch begins to slip: When shifting gears while riding the motorcycle, there is a sensation of clutch plate slippage. Engine oil becomes very thin: After a short period of running with low-quality engine oil, when the dipstick is pulled out, the oil appears very thin.
I've only been riding a motorcycle for half a year. That time I tried to save money by buying cheap, low-quality oil. Just a few days after changing it, I noticed the engine started making a drum-like thumping noise, especially when climbing hills or accelerating—it was so loud it nearly deafened me. When starting, the bike would hiccup constantly, requiring me to twist the key for ages before it would move. Acceleration felt weak, as if it hadn't had enough to eat. Later, when I checked the oil level, there was a layer of black sludge with a slightly burnt smell. The mechanic said the poor lubrication accelerated internal wear—short-term it might be fine, but long-term it would damage engine parts. Everyone, remember to choose reputable brand oils and change them regularly. Don’t try to save small money only to suffer big losses. After I changed the oil, the noise immediately reduced significantly.
I've been riding motorcycles for over a decade. Once I tried using counterfeit engine oil, and the symptoms were obvious: the engine heated up quickly to the point of being scalding hot, there was a rumbling noise after stopping, and acceleration was sluggish like an old ox pulling a cart. Over time, the poor oil quality increased friction between the pistons and cylinders, causing faint blue smoke, and fuel consumption also rose sharply. In the end, a check-up revealed that the seals were worn through. Good engine oil acts like a shield, protecting the lifespan of internal components. The money saved on inferior oil was all spent on repairs. Friends, pay attention to warning signs early to prevent major problems.
I've been tinkering with motorcycles for a while, and the issues with low-quality oil are slow starts, loud noises, engine overheating, and weak power. Insufficient lubrication leads to dry grinding of bearings and gears, resulting in a hoarse sound. Mid-ride, the bike might suddenly lose power and drop, forcing you to pull over and rest. It's advisable to regularly check the oil's color and viscosity. If it's cloudy or thin, change it immediately to avoid total engine failure.
