GL-3 Grade is a gear oil for manual gearboxes and for helical and spiral gearboxes. Grades: GL3 68, GL3 100, GL3 220, GL3 320, GL3 680. API 1560 lists GL-3 as an inactive designation, originally for manual transmissions under moderate to severe conditions and spiral-bevel axles under mild to moderate conditions; it is not intended for hypoid axles.

Overview
GL-3 Grade is a gear oil for manual gearboxes and for helical and spiral gearboxes. Grades: GL3 68, GL3 100, GL3 220, GL3 320, GL3 680. API 1560 lists GL-3 as an inactive designation, originally for manual transmissions under moderate to severe conditions and spiral-bevel axles under mild to moderate conditions; it is not intended for hypoid axles.
Every grade has its own row in the specification table, with viscosity at 100 °C, viscosity index, flash point, pour point and density.
Application
Gearboxes whose documentation specifies a GL-3 oil.
Application
Enclosed helical and spiral gear units, as listed in the product's source documentation.
