Fully synthetic 75W85 GL-4 gear oil for manual transmission (US Quart)
Red Line MT85 is a 75W85 GL-4 gear oil that satisfies the gear oil viscosity requirments of 80, 75W85 and motor oil viscosities of SAE 30 and 5W30.

Red Line MT85 offers high performance gear protection and longer synchro life. It offers quicker shifts and provides a perfect synchronized coefficient of friction, eliminating notchy shifting, even when cold.

MT85 can be used in GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified. It is safe for brass synchros because it lacks the reactive sulphurs found in most GL-5 oils that cause damage.
