Motul Gear 300 LS 75W-90 Synthetic Racing Gear Oil 20 Liter Pail

Motul Gear 300 LS 75W-90 is a high-performance synthetic ester-based transmission lubricant developed for racing, performance, and heavily loaded mechanical transmissions.

It is designed for limited-slip differentials, gearboxes with integrated limited-slip differentials, synchronized or non-synchronized manual transmissions, transfer cases, and hypoid differentials operating under shock loads, heavy loads, or high rotational speeds.

Advanced ESTER Core technology provides strong oil-film protection, low friction, high shear stability, smooth gear engagement, and reliable power delivery. Its SAE 75W-90 viscosity can also improve transmission efficiency and reduce drag compared with compatible applications using a heavier 75W-140 lubricant.

This package includes one 20-liter pail for race teams, performance workshops, professional service facilities, and high-volume transmission maintenance.

WHY THIS GEAR OIL:

The synthetic ester-based formulation delivers high lubricating strength to reduce friction and protect gears, bearings, synchronizers, and differential components under severe loads.

Integrated limited-slip friction performance supports smooth and dependable operation in compatible plate-type limited-slip differentials.

Excellent shear stability helps the lubricant maintain its protective viscosity during racing, repeated high-load operation, and elevated transmission temperatures.

Strong low-temperature fluidity supports easier cold shifting and reduced gear-lever effort.

Its lower transmission drag can improve efficiency, shifting response, and power delivery compared with a heavier viscosity where 75W-90 is permitted.

The formulation provides anti-corrosion, anti-foam, and anti-emulsion protection and is compatible with common gearbox seals and yellow-metal components.

FITMENT AND COMPATIBILITY NOTE:

Use only in mechanical transmissions or differentials requiring a compatible SAE 75W-90, API GL-4, or API GL-5 lubricant.

The listed performance levels do not make this product suitable for every manual transmission, transfer case, or differential. Verify the required viscosity, GL classification, limited-slip design, friction requirements, fluid capacity, and service interval before use.

For limited-slip differentials, confirm that the differential manufacturer permits a gear oil with integrated limited-slip friction characteristics.

Do not use in automatic transmissions, dual-clutch transmissions, continuously variable transmissions, or applications requiring a dedicated ATF unless specifically authorized.

IMPORTANT NOTES:

Follow the transmission or differential manufacturer’s specified drain interval and adjust it for racing, severe loads, high temperatures, water exposure, or frequent competition use.

Some limited-slip differentials may require a specific friction modifier or proprietary fluid. Confirm compatibility before filling.

Do not mix with incompatible transmission fluids. A complete drain and refill is preferred when changing lubricant types.

Fill only to the manufacturer’s specified level. Overfilling or underfilling can cause overheating, foaming, leakage, or component damage.

Store the pail tightly closed in a clean, dry area protected from moisture and contamination.
