API GL-4 is a specification set by the American Petroleum Institute (API) for automotive gear oils. It defines the performance requirements for gear lubricants used in hypoid gears and other types of gear systems, particularly in manual transmissions and differentials. API GL-4 oils provide a balance of protection against wear, corrosion, and oxidation while also ensuring compatibility with various seal materials. This specification is crucial for maintaining the performance and longevity of gear systems in vehicles.
Total Weight
frequency modulation
API gravity is inversally proportional to the specific gravity. so if the value of spcific gravity for some material is higher , it means that the API gravity of the same material will be lower.
API [Application Programming Interface]
EP is for Extreme Pressure , cn't answer the tech though.
