Selection guidance
Confirm viscosity and service classification together.
A gear-oil request should identify the component, operating conditions, viscosity grade and required performance level. GL-4 and GL-5 are not automatic substitutes, and industrial ISO grades should be matched to the gearbox manufacturer's recommendation.
Include these details
- SAE or ISO viscosity grade
- GL classification or equipment specification
- Differential, manual gearbox or industrial gear set
