Ultimate Shifting Precision: Red Line MTL 75W80 GL-4 Synthetic Gear Oil

Achieve the smoothest, fastest shifts possible in your manual transmission with Red Line MTL 75W80 GL-4 Gear Oil (Part #50204), available now at Straight Six Imports. This product is the definitive solution for transmissions that require a lightweight, specific ⁴$75\text{W}80$ viscosity and demand the robust protection of a dedicated, synchronizer-safe fluid.

MTL (Manual Transmission Lubricant) is built on Red Line's signature ester-based synthetic formula, offering superior performance that drastically reduces notchiness, even in cold temperatures, while providing high-quality protection against wear.

Why MTL is Essential for Lightweight Transmissions:

• Ideal 75W80 Viscosity: Perfectly matches the factory fluid requirements for many Honda, Acura, BMW, and other European transmissions, ensuring optimal hydraulic performance of the synchros.

• Brass Synchro Safety: Formulated with non-corrosive friction modifiers, making it completely safe for brass and bronze synchronizers—a critical feature for many high-performance transmissions where GL-5 oil would cause damage.

• Smoother Cold Shifting: The lightweight 75W80 viscosity, combined with excellent cold flow properties, eliminates the frustrating "morning stiffness" or notchiness often felt before the transmission warms up.

• High-Temperature Stability: The synthetic ester base provides a shear-stable film that resists thermal breakdown under heavy track or performance use, crucial for protecting gears and shafts.

• GL-4 Protection: Provides the extreme pressure (EP) protection required for modern manual transmissions and transaxles.
