REDLINE MT90 75W90 GL-4 Gear Oil, US Quart (946ml)

Recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified. Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. Not for use in differentials with hypoid gears.
