What are the temperature conditions for engine oil storage?
2 Answers
Engine oil should be stored at a temperature between 23-30 degrees Celsius. Below is relevant information about engine oil: 1. Four-stroke engine oil: The winter oil grades in the SAE lubricant viscosity classification are 0W, 5W, 10W, 15W, 20W, and 25W. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 2. Two-stroke engine oil: Two-stroke gasoline engine oil has two viscosity grades, namely SAE20 and SAE30. Generally, SAE30 is selected. If it is separate lubrication, used in cold regions, or for ultra-light load two-stroke engines, SAE20 is used.
While organizing tools in my garage recently, I noticed the importance of proper motor oil storage temperature based on a painful lesson. Last summer, I accidentally left bottled motor oil in my trunk where temperatures soared above 40°C, causing the oil to thin and separate – nearly damaging my engine. Research later taught me that motor oil should ideally be stored between 10-30°C. Excessive heat accelerates oxidation and degradation, reducing lubricating properties, while sub-zero temperatures can thicken the oil or even solidify it, making pouring difficult and potentially clogging oil passages. I now recommend storing oil in basements or shaded storage rooms, avoiding direct sunlight or extremely hot vehicle compartments. In winter, avoid balconies where bottle openings might freeze. Pay attention to shelf life too – properly stored oil lasts 3-5 years, but unstable temperatures can shorten this. Implement regular storage location checks, and consider using a thermometer for added peace of mind. Don't repeat my careless mistake.
