GL5 85W140 is a gear oil specification commonly used in automotive applications, particularly for differential gears and manual transmissions. GL5 refers to the performance specification of the gear oil, while 85W140 represents its viscosity rating.
GL5 gear oils are formulated to provide excellent protection and lubrication for high-stress gear systems, such as those found in heavy-duty vehicles and off-road vehicles. They offer superior load-carrying capacity, thermal stability, and anti-wear properties to ensure smooth operation and prevent premature wear and damage to gears and bearings.
The viscosity rating of 85W140 indicates the oil’s flow characteristics at different temperatures. The “85W” part represents its winter viscosity, indicating that the oil has suitable flow properties in colder temperatures. The “140” part represents its viscosity at high temperatures, indicating its ability to maintain proper lubrication and protection under extreme operating conditions.
It is important to consult your vehicle’s owner manual or the manufacturer’s recommendations to determine the specific gear oil viscosity and specification required for your vehicle’s differential or manual transmission. Using the correct GL5 85W140 gear oil can help ensure optimal performance, longevity, and protection for your gear system.
