What Are the Different Types of Motor Oil?
1 Answers
Common motor oil types include 5W-30, 10W-30, 10W-40, 15W-40, and 20W-50. Below is relevant information about motor oil: 1. Viscosity grades of motor oil: Divided into two viscosity grades: low-temperature viscosity grade and high-temperature viscosity grade. 2. The impact of motor oil viscosity: SAE lubricant viscosity grades are 20, 30, 40, and 50. The higher the number, the greater the viscosity. Viscosity can be adjusted within a certain range, becoming thicker when hot and thinner when cold, which helps reduce engine resistance and wear.
