What Oil Can Replace Gear Oil?
2 Answers
No oil can replace gear oil. Here is the relevant introduction about gear oil: 1. Classification of gear oil: 75w90 gear oil is one specification of gear oil. Ordinary vehicle gear oils are divided into three specifications according to different viscosities: 80W/90, 85W/90, and 90. Medium-duty vehicle gear oils have five specifications based on different viscosities: 75W, 80W/90, 85W/90, 90, and 85W/40. Heavy-duty vehicle gear oils also have five specifications based on different viscosities: 75W, 80W/90, 85W/90, 90, and 85W/40. Gear oil can be divided into two categories: automotive gear oil and industrial gear oil. 2. Uses of gear oil: Automotive gear oil is used to lubricate various manual transmissions and gear drive shafts in vehicles, while industrial gear oil is used to lubricate gear devices in various industries such as metallurgy, coal, cement, and chemical industries.
I've encountered many beginners looking for oil substitutes for gear oil, but to be honest, gear oil is specifically designed for transmissions and differentials to withstand high pressure and friction. Regular engine oil lacks the necessary viscosity and can easily lead to gear wear or overheating. In emergencies, such as when a car breaks down, some people have used automatic transmission fluid (ATF) or manual transmission fluid as a temporary substitute for a few days, but it's only a stopgap measure with significant risks. Long-term use of substitutes may result in component failure. Remember, gear oil contains unique anti-wear additives that other oils don't have. It's always advisable to consult the vehicle manual for the correct oil specification to avoid expensive repairs. Additionally, regular checks of gear oil can prevent problems before they occur.
