Best Gear Oil Additives

Royal Purple 01300 Set of 3 Max Gear 75W-90 Oil 1-Quart Bottles

Royal Purple engineered this ultra-tough, high performance automotive hypoid gear oil to provide maximum protection to heavily loaded gears while maximizing power throughout the drive train. Max Gear outperforms ordinary gear oils by combining the highest quality synthetic oils with Royal Purple’s proprietary Synerlec additive technology..
Maximizes horsepower, Extends gear and bearing life, Reduces operating temperature, Severe service performance, Lower coefficient of friction, Superior corrosion protection.
Superior corosion protection, Seperates rapidly from water, Meets warranty requirements, Environmentally responsible, Formulated for limited-slip differential use.
Max Gear makes gears run smoother, quieter, cooler and longer without overhauls. A direct reduction of drag in the drive train has huge advantage for trucks and other 4-wheel drive vehicles: better gas mileage. Max Gear is formulated with a friction modifier additive – no additional additives are necessary..
