WebThe number before “W” is the low temperature oil viscosity. It’s measured at -17.8°C (0°F) and simulates the vehicle startup conditions in winter. The lower this number is, the thinner the oil in lower temperature settings. So, 0W-20 is pretty smooth-flowing, low viscosity oil in cold startups. The number after the “W” is the high ... WebThe SAE 30 oil is rated only for hot viscosity. This rating indicates how viscous the motor oil is at an operating temperature of 100 O C (212 O F). Why is this important? Temperature has a direct impact on viscosity. If an engine heats up beyond certain temperature thresholds, the motor oil will experience thermal breakdown and start to degrade.
