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.
Grades & published data
Typical values from the product data sheet, each with its test method.
Overview
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.
Application
Gearboxes whose documentation specifies GL-1, under usual operating conditions.
Application
As listed in the product's source documentation.
Feature
GL1 90: KV100 17 cSt, VI 95, pour point -18 °C, flash point 220 °C; GL1 140: KV100 24 cSt, VI 100, pour point -12 °C, flash point 230 °C.
Order the grade that matches the viscosity and API designation in the gearbox or axle manual. Each grade's values are listed separately in the specification table.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
