What Does the W Stand for in 10w30?

Answer

In 10w30, the letter W stands for winter. The SAE (Society of Automotive Engineers) launched a series of viscosity classifications at both 100 and at 0 degrees Celsius. When there is a 'W' in the SAE classification, it means the oil is rated for low temperature use. The SAE 10W30 meets the requirements for 10-weight oil at cold temperatures as well as 30-weight oil at high temperatures.
