What Grade of Engine Oil Should Be Used in Winter?
1 Answers
In northern regions, using 5W-30 viscosity engine oil in winter should be fine. Engine oil starting with 5W can be used in low-temperature environments above -30 degrees Celsius. In Jilin area, winter temperatures are around -20 degrees Celsius, so 5W-30 viscosity engine oil is suitable. Here are some related introductions about engine oil: 1. In regions where winter temperatures drop below -20 degrees Celsius, it is recommended to use engine oil starting with 0W. 0W engine oil can handle low temperatures around -35 degrees Celsius, with better low-temperature fluidity than 5W, making it easier to start the engine during cold winter starts. The 30 viscosity needs to be selected based on the vehicle model, as different brands of vehicles have certain differences in requirements for oil viscosity and certification standards. It is best to choose engine oil according to the manufacturer's requirements. 2. Engine oil used in winter must meet three main characteristics: low viscosity, low pour point, and good anti-wear properties to provide excellent protection for the engine. Winter temperatures are relatively low, so the fluidity of engine oil in cold conditions is poor. Some engine oils may even solidify in environments below -10 degrees Celsius, so winter engine oil needs to have good low-temperature fluidity.
