Can 5W30 engine oil be used for long-distance driving in summer?
2 Answers
5W30 engine oil can be used for long-distance driving in summer. The following is a detailed introduction to engine oil types: 1. High-temperature type: such as SAE20-SAE50, the number indicates the viscosity at 100*C, the larger the number, the higher the viscosity. 2. Low-temperature type: such as SAEOW-SAE25W, W means it is only used in winter, the smaller the number, the lower the viscosity and the better the low-temperature fluidity. 3. All-weather type: such as SAE15W/40, 10W/40, 5W/50, indicating that the viscosity grade at low temperature meets the requirements of SAE15W, 10W, 5W respectively, and the viscosity grade at high temperature meets the requirements of SAE40, 50 respectively, which is a winter-summer universal type.
When it comes to whether 5W30 oil can handle long-distance driving in summer, I think it's completely fine. As an automotive modification enthusiast who often helps friends maintain their cars, I can confirm that the "30" in 5W30 is specifically designed for high temperatures. Its viscosity at 100°C is ideal for summer conditions, and even several hours of continuous driving won't cause issues. The key is to ensure sufficient oil levels - always check the dipstick before long trips to confirm it's above the minimum mark. While summer heat does accelerate oil degradation, using full synthetic oil significantly improves durability. Additionally, monitor oil pressure to prevent engine overheating. For optimal safety, consider changing to fresh oil before embarking on long journeys - after all, safety comes first.
