Red Line Synthetic Oil Friction Modifier and Break-In Additive is formulated for clutch-type limited-slip differentials and posi-traction units. Supplied in a 4 US fl oz bottle, this additive helps improve differential operation when used with compatible petroleum or synthetic gear oils. Manufacturer part number 80301 and vendor part number 80301 identify this Red Line Synthetic Oil formulation.
Designed to address limited-slip chatter, the additive can be introduced gradually at a rate of 1 US fl oz at a time until the desired performance is achieved. It is also suitable for break-in applications, where it can help reduce operating temperatures by as much as 50°F under appropriate conditions. Always follow the differential manufacturer’s service recommendations and verify fluid compatibility before use.
Fitment: Suitable for automotive differentials equipped with clutch-type limited-slip or posi-traction units that require a friction modifier or break-in additive. Compatible with both petroleum-based and synthetic gear oils, making it a practical choice for many performance, racing, restoration, and drivetrain service applications. Red Line Synthetic Oil Part Number 80301 is intended for use as an additive rather than a standalone gear lubricant.
