Do I Need to Change to Antifreeze Engine Oil in Winter?

[LaReed]

If the engine oil grade is below 5W, it is absolutely unnecessary to switch to winter oil. Conditions for changing engine oil: Generally, 0W and 5W grade oils are relatively more expensive. Some older or low-end models may come with 10W or 15W grade oil as standard, or some car owners might opt for higher-grade oil for convenience and cost-saving. In such cases, it is necessary to switch to a lower-grade oil in winter. Additionally, for larger vehicles, due to engine operating conditions and long-distance, prolonged usage, the oil grade used may differ from that of regular household vehicles, often requiring higher-grade oil. These vehicles also need to switch to lower-grade oil in winter. Precautions regarding engine oil: Engine oil itself is a blend of base oil and additives. Under normal circumstances, if you choose high-quality oil, there is no need to add any additional oil additives. Indiscriminate use of oil additives not only fails to protect the vehicle but may also cause chemical changes in the oil, leading to a decline in the oil's overall performance.
