Lubricating oil between piston and cylinder wall in engine will inevitably participate in combustion. As long as it does not exceed one liter within five thousand kilometers, it is normal fuel consumption, and vice versa.

Burning oil is basically caused by piston ring sticking. As long as there is no serious strain on the cylinder wall, there is no need for overhaul. Replacing high viscosity engine oil to maintain it is only a stopgap measure, which is harmful and useless.

Solution of engine oil combustion

In the habitual thinking of riders, it is always believed that burning engine oil requires overhaul, which not only bears high maintenance costs, but also bears unpredictable risks and depreciation losses caused by vehicle overhaul. Destroy the sealing and accuracy of the engine. Moreover, it is possible to burn oil after tens of thousands of kilometers, so overhauling the engine is unsustainable.

Now the demolition-free technology is very mature and gradually accepted by the majority of car owners. In particular, Siyoupu owns PNF patented non-destructive repair products, completely getting rid of the technical shackles that engine oil must be overhauled in the garage. Without disassembling a screw, the piston ring is repaired and released during driving, and the effect is remarkable.
