Red Line Synthetic Oil formulates a full range of Polyol Ester based GL-4 transmission lubricants, rather that offering a one product suits all across GL-4 & GL-5 Red Line offers lubricants to pinpoint nearly every transmission application for optimum performance.
Red Line Offers the most complete line of GL-5 gear lubricants optimised for differentail, transmission or transaxle use. These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation.
Acting like a liquid grease, the unique Red Line Shockproof lubricants contain a suspension of solid microscopic particles as an extreme pressure agent, offering a "best of both worlds" balance of low drag and superior protection for gear teeth.
With eight different combinations of viscosity, slipperiness, and OE-recommended additives packages, Red Line offers the widest selection of ATF available.
