At any time, we must avoid stepping on the accelerator, in addition to safety considerations, but also because we must be better to the car. Maybe you can drive a car, but do you know this knowledge about cars?


1. Do not step on the accelerator hard after a cold start.


This can cause damage to the engine, especially in winter. Another part of the reason is that because the oil has not been lubricated, the engine and the parts have been rubbing against each other very dry before, which will increase the wear of the engine.


Another part of the reason is that the gasification of gasoline is not complete because the vehicle has not reached the normal operating temperature. Activating the throttle increases the load on the engine.


Before the water temperature has completely risen, do not press the accelerator hard and keep driving at a constant speed.


We must avoid slamming on the accelerator at all times.


2. Why are the tires black instead of colored?


In order to increase wear resistance and safety, chemical elements are added to the rubber, so that the tire turns black.


3.The maintenance cycle of the car.


Generally, a normal car needs to be maintained once every 5,000 kilometers. However, the advantages of maintenance outweigh the disadvantages for the vehicle itself. You can decide how often to perform maintenance according to the state of the car.

(2) Purchase scratch repair products to remove small scratches.


Wash the car and apply a purchased repair product to the scratches. Then wipe off the remaining product with a clean cloth, the same can be repeated 2-3 times.
