In summer, the ambient temperature is high. If the oil is selected improperly, it is easy to cause the oil pressure to be too low, and the engine can be damaged in severe cases. Therefore, vehicles must pay attention to the correct selection and use of lubricants.
The ambient temperature is relatively high, and the engine is often in a high temperature state, which easily causes the lubricating oil to oxidize and deteriorate, reduce its viscosity, and lose its lubricating function. Therefore, special attention should be paid to the engine cooling system in summer to ensure that it can work normally and avoid overheating of the engine.
The viscosity of the lubricating oil changes with the increase of temperature, that is, the viscosity of the lubricating oil decreases when it is heated, which is easy to cause the lubricating oil to consume too quickly, so in summer, pay special attention to frequently checking the oil dipstick, and if there is any defect, it should be refilled in time.
Frequent heavy-duty or older cars can choose 50 or 20w/50 oil. Avoid excessively low oil pressure due to low lubricating oil viscosity, causing unnecessary failures. In addition, pay attention to the engine water temperature and oil pressure at all times. If there is any abnormality, stop and find the cause immediately, and then continue driving after troubleshooting.
