About SEVERE GEAR 80W-90 Gear Lube
SEVERE GEAR 80W-90 is a gear lubricant to consider for a differential or other assembly that specifies this viscosity and the applicable gear-oil standard. It belongs in the drivetrain service plan alongside the correct fill quantity and inspection procedure.
Before you choose
Confirm the assembly calls for 80W-90, verify its required gear-oil specification, and check limited-slip friction-modifier requirements. A differential lubricant is not automatically suitable for a synchronized manual transmission.
Can I use this in any manual transmission?
No. Manual transmissions can have specific friction and material-compatibility requirements. Use a fluid explicitly listed for the transmission’s required specification.
