What does gear oil API GL 5 SAE 85W 140 mean

Gear oils can be divided into two categories: automotive gear oils and industrial gear oils. The former is used to lubricate various automotive manual transmissions.

and geared shafts.

The latter is used to lubricate gear units in various industries such as metallurgy, coal, cement, and chemicals.

Automobile gear oil is divided into five gears (GL-1 GL-5). The GL-5 has the highest level of performance.

Viscosity classification method, divided into 70w, 75w, 80w, 85w seven viscosity grades. "w" stands for winter. Without the word "w", it is a non-winter oil.

XXW XX is a general purpose gear oil for winter and summer. They are divided according to 100 kinematic viscosity. The main ones used in the market are SAE75W 90, SAE85W 90, 85W 140, which are used in winter and summer.

Automotive gear oil 85w-140 means that the gear oil is a multi-grade oil, there are two grades of 85w and 140, and the applicable ambient temperature is 26 50.

SAE viscosity classification divides gear oils into 75W, 80W, 85W and other grades.

These oils are specified for a variety of gears used in automobiles and other automotive equipment at high speeds and shock loads, high speeds with low torque, and low speeds with high torques, especially hyperboloid gears, and are suitable for heavy-duty gears.

Automotive gear oils. API (American Petroleum Institute) is divided into seven viscosity grades of 70W, 75W, 80W, and 85W according to the viscosity classification method. "w" stands for winter. None

The word w is for non-winter oil.

XXW XX is a winter and summer general purpose gear oil, and they are divided according to a kinematic viscosity of 100.

The main ones used in the market are SAE75W 90, SAE85W 90, 85W 140, this kind of oil is universal in winter and summer, and the oil temperature shall not exceed 85-90 during work.

Gear oil API GL-5; SAE 85W-140 means the American Petroleum Institute's standard for vehicle gear oil quality level 5, and the American Society of Automotive Engineers standard for low-temperature viscosity 85 oil in winter.

On the outer packaging of the gear oil, you will see SAE and API. SAE is the abbreviation of the Society of Automotive Engineers, and API is the abbreviation of the American Petroleum Institute. The designation on the back of the SAE indicates the viscosity value of the gear oil, while the designation on the back of the API indicates the quality grade of the gear oil.

W stands for winter, and the higher the number in front of it, the better the low temperature fluidity of the gear oil, the lower the ambient temperature available for use, and the better the protection ability during cold start.

Gear oil API GL-5 American Petroleum Institute (API) vehicle gear oil performance classification GL-5. SAE 85W-140 is a winter oil with a viscosity of No. 85 and No. 140 oil in the viscosity grade standard for motor oils formulated by SAE International (SAE International).

The American Petroleum Institute (API) vehicle gear oil performance classification is divided into: GL-1, GL-2, GL-3, GL-4, GL-5 five grades, GL-5 is more demanding than GL-4 resistant to low-speed high-torque, high-speed low-torque and high-speed, impact load hypoid gears. The parts used are differential gears and rear axle gears with particularly harsh working conditions.

The larger the number of SAE viscosity series, the higher the applicable temperature, and the grade with the suffix W is suitable for winter; Grades without the suffix W are suitable for both the usual and summer seasons; If the two numbers are connected together, it means that it is a multi-grade oil, and its performance meets the requirements of two viscosity grades.

Similar to 10W-30, there are two viscous targets, one is 10W and the other is 30, and this oil has the combined characteristics of SAE 10W and SAE 30.
