GL-5 Grade is a synthetic transmission oil for certain manual gearboxes and axles, and for moderately to heavily loaded on- and off-road driveline applications. Grades: GL5 75W80, GL5 85W90, GL5 90, GL5 140, GL5 85W140. API 1560 describes GL-5 as intended for gears, particularly hypoid gears, in axles under high-speed shock load and low-speed, high-torque conditions.
Every grade has its own row in the specification table, with viscosity at 100 °C, viscosity index, flash point, pour point and density.
GL-I Grade is a gear oil based on mineral base oils and additives for vehicle gearboxes under usual operating conditions. Grades: GL1 90, GL1 140. API 1560 lists GL-1 as an inactive designation for manual transmissions under mild conditions, and notes that it is generally unsatisfactory for most passenger-car manual transmissions.
Every grade has its own row in the specification table, with viscosity at 100 °C, viscosity index, flash point, pour point and density.
High-Performance is an antifreeze / anti-boil engine coolant for vehicle cooling systems. It is diluted with water according to the vehicle manufacturer's instructions.
Published values are a density of 1145 kg/m³ at 15 °C and a reserve alkalinity of 5.6 mL of 0.100 N HCl (ASTM D1121); the pH of a 33 % by volume solution in water (ASTM D1287) is also listed. Reserve alkalinity measures the coolant's capacity to neutralise acids that form in service.
Mineral-Based is a mineral-based antifreeze / anti-boil engine coolant for vehicle cooling systems. It is diluted with water according to the vehicle manufacturer's instructions.
Published values are a density of 1134 kg/m³ at 15 °C and a reserve alkalinity of 18 mL of 0.100 N HCl (ASTM D1121); the pH of a 33 % by volume solution in water (ASTM D1287) is also listed. Reserve alkalinity measures the coolant's capacity to neutralise acids that form in service.
