Precautions for engine use:

1. Warm-up of cold car When starting the engine in the cold car state, it needs to be warmed up. At normal working temperature, the running resistance, wear and stability between parts are the best, so preheating is needed.

2. Avoid overload, and try to keep the engine speed below the red scale of the tachometer to avoid engine overload. Try not to delay the car with manual transmission.

3. Use qualified fuel. Use qualified fuel. The quality of fuel has a great influence on the combustion of engine. Inferior gasoline will produce a large number of carbon deposits and rubber deposits in the combustion chamber, fuel injector, air intake and valve, which will make the engine idling unstable and difficult to accelerate.
