Can Gear Oil Be Used as Engine Oil?
1 Answers
Gear oil cannot be used as engine oil. Below are specific details about gear oil: Introduction: Gear oil is a type of lubricating oil primarily composed of petroleum-based lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents. Its main functions include lubricating gears and bearings, preventing wear and rust, and assisting in heat dissipation for gears. Function: Gear oil should possess excellent anti-wear and load-bearing properties, along with suitable viscosity. Additionally, it should have good thermal oxidation stability, anti-foaming characteristics, water separation performance, and rust prevention capabilities. Since gear loads typically exceed 490 MPa, with hypoid gear surface loads reaching as high as 2942 MPa, gear oil accounts for approximately 6% to 8% of the total lubricant consumption.
