ReviewsApi Gl 4 Gear Oil

Royal Purple 01300 Max-Gear Synthetic Gear Lube Oil 75W90 Case of 12 Quarts

Recommended for use in truck & automotive front or rear differentials/manual transmissions/lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. // Formulated for limited slip differential use..
Maximizes horsepower. // Extends gear & bearing life..
Reduces operating temperature. // Lower co-efficient of friction..
Superior corrosion protection. // Separates rapidly from water..
Max Gear makes gears run smoother/quieter/cooler/longer without overhauls..

Seal Conditioner – stops current and prevents future leaks by protecting and reconditioning seals..
Extreme Pressure (EP) and Anti-Wear (AW) Agents – provide excellent metal-to-metal wear protection reducing noise and gear temperatures. Our sulfur, nitrogen and phosphorus additives meet the requirements of API GL-4 and GL-5 specifications..
Friction Modifier – supplements the EP/AW additives to help reduce noise and wear. This in turn helps shifting in a manual transmission and also stops chatter in limited-slip posi-traction axles..
Performance Additive Booster – includes tackifying agents and highly sheer-stable multigrade viscosity modifiers to keep oil on the gears and bearings where it can better lubricate, especially at higher temperatures. Pour Point Depressant (PPD) allows product to flow even at very low temps..
Manufactured in the USA, this product works in all manual gearboxes, differentials, open & posi axles and more. Stops pinion, axle, output shaft and other seal leaks. Reduces grinding, whining, clunking and protects gears..

Our lowest viscosity, most shear-stable ATF for consistent operation, designed to satisfy Dexron-VI, MerconSP, MerconLV, Honda DW-1, Toyota WS, Mercedes Benz NAG-2, ZF-LG 6, 6+ and 8 fluids, for use in automatic and manual transmissions.
Also satisfies API 70W/75W and GL-4 gear oil requirements.
Red Line offers the widest selection of fully-synthetic ATF on the market today.
Reduced oxidation and lower volatility at high temperature.
Allows high-temp operation without varnishing valves and clutches.

HIGH PERFORMANCE - Gear protection and longer synchro life. Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified.
OFFERS QUICKER SHIFTS - Excellent gear and synchro protection, balanced friction control & slipperiness for easier shifting even in cold climates.
SAFE FOR BRASS SYNCHROS - GL-4 Gear Oil lacks the reactive sulfurs found in most GL-5 oils that cause damage. Recommended for GL-1, GL-3 & GL-4 applications.
