Land Rover found that the idle speed of four cars was slightly shaken after driving for 90,000 kilometers.

Land Rover found that the slight jitter of the clarinet at an idle speed of 90,000 kilometers does not represent a problem, but it is a problem in the long run. Long-term blackening means long-term bad combustion, which means long-term high temperature of the engine. The engine is most afraid of high temperature when starting, and the engine will be damaged too quickly after a long time. All kinds of fittings are accelerated aging, and the carbon deposit on the aging piston ring of oil seal is formed in this way. There must be a lot of carbon deposit in the combustion chamber. Therefore, regular cleaning is definitely no problem. It needs to be cleaned regularly, and the fuel tank of the gas station needs to be cleaned every two months. In addition, the fuel tank of the family car is not sealed. Adding spectral fuel additives to the fuel tank can complete cleaning.
