What to check before choosing gear oil.

Gear oil may be used in different applications, including selected transmissions, axles and differentials. The correct choice is tied to the component and its manufacturer’s requirement.

Identify the exact component

Confirm whether the requirement relates to a transmission, axle, differential or another gear application. Do not assume that one gear oil applies to every drivetrain component.

Check the manual and label

Use the manufacturer’s documentation to confirm the required viscosity grade and performance classification. Compare it with the product label before selecting a pack.

Share the operating context

Vehicle type, load, route and duty cycle can help frame a product-guidance conversation. They should be considered alongside—not instead of—the documented requirement.
