Which Cars Can Use 10W-40 Engine Oil?
1 Answers
This depends on the vehicle's operating environment and local temperatures to determine which cars are suitable for 10W-40 engine oil. Here are the relevant details: 1. Viscosity value: 10W-40 is the SAE standard viscosity rating for engine oil. This viscosity value first indicates that this oil is a multi-grade lubricant. The W stands for WINTER, and the number before W represents the pour point temperature, simply put, the freezing point temperature. 2. Freezing point temperature: The freezing point temperature for 10W oil is -25°C. Other common ratings are 0W at -35°C, 5W at -30°C, and 15W at -20°C. The number after W represents the oil's kinematic viscosity at 100°C, with higher numbers indicating higher viscosity. 40 means the kinematic viscosity standard at 100°C is between 12.5mm2/s and 16.3mm2/s, and it definitely does not mean, as some rumors suggest, that it can be used below 40°C.
