Gear oil with SAE approval

SAE

— a family of standards developed by the association of the same name. This parameter should not be confused with SAE viscosity (see the relevant paragraph) - this refers to separate standards with their own specific requirements.

Most often, modern oils for manual transmissions comply with the SAE J2360 standard. It stipulates that the oil “exceeds the requirements of API GL-5” and is intended for use in hypoid gears operating under increased loads (including high speed or high traction at low speed) and having a large number of surfaces in contact with sliding.
