Do Cars Need to Change to Antifreeze Engine Oil in Winter?
1 Answers
Whether a car needs to change engine oil in winter mainly depends on whether the original oil is suitable for the driving environment conditions and driving habits. If the local climate is cold, it is recommended to switch to winter engine oil. Meaning of engine oil specifications: The "W" in the engine oil specification stands for "winter," indicating that the oil can be used normally in winter. The number before "W" represents the oil's low-temperature fluidity. For example, 0W means the oil can flow normally at temperatures as low as -35 degrees Celsius. The number after "W" indicates the oil's high-temperature viscosity—the higher the number, the greater the viscosity. Functions of engine oil: Engine oil is often referred to as the "blood" of the engine. Without oil, the engine cannot operate properly. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat.
