As the Spring Festival is approaching, I believe many of my friends are thinking about where to go for a self-driving tour. However, before self-driving tours, it is necessary to carefully inspect the vehicle to eliminate potential safety hazards. The following inspection items are essential.

tire pressure

In winter, the temperature is low and the road is slippery, so proper tire pressure is very important. If the tire pressure is too low, not only the fuel economy of the vehicle will be deteriorated, but also tire wear will be accelerated; if the tire pressure is too high, it will affect the The braking performance of the vehicle and the risk of loss of control on slippery surfaces. Therefore, it is recommended that you check the manufacturer’s recommended tire pressure on the fuel tank cap or door of the vehicle, and adjust the tire pressure to the range recommended by the manufacturer to ensure driving safety.

Engine oil

As the lubricating oil of the engine, oil plays a vital role in the normal driving of the vehicle. If there is too much oil, the resistance of the engine will become larger, and the fuel economy of the vehicle will become worse, which will affect the normal operation of the engine in severe cases; if there is too little oil, the engine will not be fully lubricated, and the metal The friction between them will cause irreversible damage to the inside of the engine, and even lead to overhaul of the engine. Therefore, if the oil is low, it needs to be replenished in time to prevent the vehicle from breaking down. In addition, for the purchase of engine oil, it is recommended that you prefer fully synthetic engine oil, which not only has excellent performance, but also has a longer replacement cycle. For self-driving tours, fully synthetic engine oil is the best choice. It is worth mentioning that when adding oil, you should choose an oil that meets the specifications of the vehicle.
