In the cold winter, if you need to replace the engine oil suitable for the season, it is recommended that you choose a type with better low-temperature fluidity. For example, for products with SAE label 10, if you are in a cold northern region (for example, the ambient temperature is within -28°C), it is recommended that you choose products with label 10W/30, such as daily labor lubricants (10W/30; 10W/40) . If you are in the south where the winter is not cold (for example, the ambient temperature is within -18°C), you can choose products with the label 15W/40, such as the 15W/40 products of the Japanese lubricant series.
The temperature in summer is higher, but compared to the high temperature of around 100°C in the engine, it is still dwarfed, so the selection of lubricating oil in summer is not very affected by the environment. Since the viscosity of synthetic lubricants currently changes less with temperature, and the engine technology produced in recent years has been updated and the components are more sophisticated, there is no need for a large lubricant viscosity. In most areas of our country, you can choose SAE15W/40 products. If your engine is older or has greater wear and tear, it is recommended that you choose SAE20W/50 products.
