The owner's own oil change will involve four problems: 1, waste oil treatment, 2, oil model and quality assurance, 3, oil filling, 4, the discovery of other problems.

Many owners think that changing the oil is a very simple matter, is not to put the oil out, and then put the new oil into it, it will be solved? But what about the waste oil that comes out? Some people say, I put it in a bottle myself and keep it for lubrication and rust removal. Surely there's nothing wrong with that? But one bottle is fine, two bottles is fine, slowly more what? It can be said that many owners of waste oil are casually poured into the sewer, which will pollute the water source. The repair shop will collect the waste oil and sell it to the waste oil recycling company, at least it will not pollute the environment.

Secondly, each model will have a model requirement for the replacement of the oil, such as the Honda scooter with a displacement below 125 only needs to replace the mineral oil of the SJ class 10W-30 each time. But some owners think that the high price is good, or some think that it is oil, the cheaper the better, go to the two extremes, if the oil model and level are not right, although the engine will not immediately fail, but the same as smoking is harmful to health, over time, it will have an impact on the engine.

The third is the amount of oil filling, because most of the oil on the market is 1L/ bottle packaging, so many owners will directly fill a liter of oil, so that the impact on the motorcycle can be immediately reflected. For example, the engine oil capacity of the split is 700 liters, if you inject 1 liter, it will produce engine power reduction, because the crankcase oil is too much, the engine for a long time to work, the engine crankshaft oil seal will be expanded to produce oil leakage phenomenon, if the transmission box side of the oil leakage, the oil leakage will have a greater impact on the transmission mechanism, It's also easy to see that the rear of the engine is covered in grease. Therefore, Honda's NSC engine is generally strictly injected with 700 liters of oil, if there are owners who do not change the oil on time, up to 800 liters of oil.

Finally, when you go to the maintenance station to change the oil, the responsible maintenance station is not only to change the oil, they will also help you check the other problems of the vehicle, and sometimes find the problem in time to eliminate the fault in the bud. So the seemingly simple oil change, there are still a lot of doors, if you do not understand, or let professional people do professional things, so it is more safe.
