75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/ Exige, Toyota.
Offers quicker shifts, perfect synchronizer coefficient of friction.
Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage.
High performance gear protection and longer synchro life.
Eliminates notchy shifting, even when cold.
Satisifies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 40, 10W40, and 15W40
Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified.
