Red Line Gear Oils and manual transmission fluids are designed to give improved gear protection at high temps. They reduce differential temps 10-70°F. Efficiency improvements between 1-5% are typical. The synthetic base stocks and additives allow the gear oils to carry higher loads compared to petroleum lubricants.

MT-85 75W85 GL-4 Recommended for Nissan 350Z and 370Z (also most Maxima, Altima & Sentra), Mitsubishi Evolution, Hyundai, and Kia applications. Many NV4500 truck transmission applications like Chevy Silverado and Dodge Ram. Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. Offers quicker shifts, perfect synchronizer coefficient of friction. Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified.
