This is a question about a backend rider leaving a message. According to the description, the problems encountered by the rider belong to some vehicle precautions beyond normal maintenance. Because under normal circumstances there is no such operation, it is completely a folk remedy.
However, based on the shared repair and car experience of the knights, this folk remedy is not beneficial to the car and can have adverse effects, so anyone who tells me that this repair method is not feasible.
The reason is simple. The motorcycle maintenance manual clearly states that refueling is not allowed on the exhaust pipe. This is a suggestion given by motorcycle manufacturers, which is equivalent to a red line that cannot be touched during the use of motorcycles. When we do not listen to advice and must do the opposite, the following adverse reactions may occur.
1. The exhaust pipe is smoking, and when lubricating oil is added to the motorcycle exhaust pipe, its intuitive reaction is black smoke, which can cause the illusion of the engine burning oil.
2. Damaging the exhaust pipes of three-way catalytic converters and electronic fuel injection motorcycles will result in a more complex structure, no longer just a simple motorcycle muffler assembly, but also an exhaust gas filtration device - the three-way catalytic converter. If the exhaust pipe enters the oil, it will affect the performance of the three-way catalyst to a certain extent, and even directly damage it. (But it also depends on the amount added)
3. Excessive exhaust emissions. In addition to noise reduction, another main task of the exhaust system is to make the exhaust more environmentally friendly. Once the system enters the engine oil, the exhaust will definitely exceed the standard. A simple black smoke can achieve this without damaging the three-way catalyst.
From the above introduction, it can be seen that the adverse effects of injecting lubricating oil into the motorcycle exhaust pipe are obvious. However, since this operation has such a significant reaction, why would anyone still create a problem to add oil to the exhaust pipe?
The main reason is the excessive love for the car, as the benefit of this operation may be to slow down the rusting inside the exhaust pipe, especially for motorcycles used in cold regions. This operation can to some extent avoid exhaust pipe corrosion caused by temperature differences, which benefits car enthusiasts and causes problems for the organizers.
Actually, this concern is completely unnecessary. As long as we keep the drainage outlet at the bottom of the exhaust pipe unobstructed, rusting and rotting are not common during the normal process. Many exhaust pipes are scrapped early because we overlooked the existence of drainage outlets, so instead of violating regulations, it is better to maintain them normally and reasonably.
From the above introduction, it can be seen that injecting oil into the exhaust pipe will not have any effect on repairing the car, but will instead cause some unnecessary trouble. Therefore, do not attempt this operation casually. We can follow the maintenance instructions in the manual. As for the maintenance of the exhaust pipe, it only requires a clean surface and unobstructed drainage outlet, without the need for too many additional solutions.
