How to Distinguish Between Engine Oil and Gear Oil?
1 Answers
Methods to distinguish between engine oil and gear oil are as follows: 1. Usage: Engine oil generally refers to the lubricating oil used in various engines, and it is the most widely used lubricant in engines. Gear oil, also known as transmission lubricating oil, is mainly used to lubricate the gears in the transmission system of automobiles and tractors, including gearboxes, reducers, and differentials. 2. Source and state: Gasoline engine oil is extracted and refined from underground oil wells. This unrefined lubricating oil is not suitable for engines, so it must undergo strict refining and the addition of various elements to effectively suppress unstable states in extreme cold and high temperatures. Gear oil has a higher viscosity than engine oil and is slightly black, hence it is also called black oil. Due to the different shapes of gear teeth, the requirements for gear oil also vary, generally divided into regular gear oil and hypoid gear oil.
