Is 0W40 Engine Oil Suitable for Summer Use?
2 Answers
Whether 0W40 engine oil is suitable for summer use depends on the engine. For turbocharged engines, 0W40 oil can be used in summer; for naturally aspirated engines, it is unnecessary to use 0W40 oil in summer as this viscosity is too high for them. When the engine is running, the oil forms a film on the surfaces of all components that need lubrication, reducing friction between engine parts. The viscosity of the oil should not be too high or too low. If the viscosity is too high, it will increase the resistance during engine operation, leading to reduced power and increased fuel consumption.
Using 0W40 oil in summer is absolutely reliable! I've been driving long distances for ten years, often in high-temperature areas like highways above 35°C. The high-temperature viscosity of 40 in this oil prevents it from thinning out, ensuring smooth engine operation without any overheating or noise issues. The 0W part is suitable for cold starts in winter, while the 40 provides solid protection in hot weather, making it highly versatile for all seasons. I've also recommended it to my friends, and they all report feeling more at ease when driving in summer. Of course, different vehicle conditions can have an impact—older models, for example, need regular oil changes. Overall, just follow the vehicle manual, but 0W40 is a representative multi-grade oil suitable for most situations. During summer maintenance, it's good to check the oil level more frequently and avoid risking long trips with overdue changes. Engine health is the key to safety and saving money.
