When the engine oil is insufficient, the bearing and journal will be poorly lubricated, which will aggravate the wear and even cause the accident of burning tile shaft.

However, if there is too much oil, the engine will also fail, that is, the crank and the big end of the connecting rod are violently stirred during work, which increases the internal power loss of the engine and the amount of oil splashed on the cylinder wall, resulting in engine oil combustion failure. Therefore, the oil should be controlled between the upper and lower marks of the dipstick.

Minefield II: Random increase of equipment in the vehicle:

There is also the habit of adding equipment at will in the car, but I don't know that this has seriously affected driving safety.

For many car owners, Mercedes-Benz Sprint RV is a mobile home. It is understandable to pursue comfort and luxury in the car, but many car owners like to install various equipment in the car. If this modification is not handled properly, it will often adversely affect the convenience and feasibility of automobile performance and handling, and even leave sequelae or affect driving safety. Must be corrected in time.

Minefield 3: car washing and car paint injury in the sun:

The taboo to protect the watering can car is to wash the car in the hot sun. Many car owners like to wash their cars in the hot sun, thinking that the water on the car body can dry quickly after washing. As we all know, when washing a car under the scorching sun, the convex lens effect formed by water droplets will cause local high temperature on the upper layer of the car paint, and the car paint will lose its luster after a long time. Therefore, car washing and waxing can be carried out under cover. If the environment cannot be guaranteed, car washing can be done in cloudy or sunny days in the morning and evening.

Minefield 4 water tank: "boiling" is busy adding water;

The water tank is "boiling", and many car owners worry that the engine temperature will rise again, so they immediately turn off the fire and add water. This is not right. The correct way is to stop the engine immediately and turn it off after the cooling water temperature drops. At this time, if the cooling water is insufficient, it should be added slowly.

Minefield 5: Long-term non-use of cars or short-distance use of cars:

After the rising cost of car use, many car owners began to drive less, and when they reached the limit, they would not drive. In this way, the surfaces of transmission parts such as engines and gearboxes will rust due to frequent direct contact with air. The best way is to let the car run for thirty or forty minutes every few days. In addition, long-term short-distance car use is also easy to hurt the car, so it is necessary to run long distances in time.
