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

Motul Gear 300 75W-90 is a high-performance synthetic ester-based racing gear oil developed for heavily loaded mechanical transmissions in performance and competition vehicles.

It is suitable for compatible synchronized and non-synchronized manual gearboxes, combined gearbox and differential units, transfer cases, reduction gear systems, and hypoid differentials without limited-slip systems.

The formulation provides exceptional shear stability, low internal friction, strong gear protection, and dependable performance under shock loads, high torque, elevated temperatures, and high rotational speeds.

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

WHY THIS GEAR OIL:

The synthetic ester formulation provides strong oil-film adhesion and high lubricating strength to protect gears, bearings, synchronizers, and other transmission components.

Exceptional shear stability helps the lubricant remain within its SAE 75W-90 viscosity grade during severe racing and high-load operation.

Low internal friction supports efficient power transmission and can help reduce drivetrain drag in compatible applications.

The SAE 90 hot-viscosity grade maintains a durable protective film at elevated operating temperatures.

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

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

BEST FOR:

Racing and high-performance vehicles

Track, speedway, rally, and rally-raid applications

Synchronized and non-synchronized manual transmissions

Combined gearbox and differential units

Transfer cases requiring compatible gear oil

Hypoid differentials without limited-slip systems

Reduction boxes and other compatible geared transmissions

Transmissions exposed to shock loads, high torque, or elevated temperatures

Professional workshops requiring a 20-liter pail

FITMENT AND COMPATIBILITY NOTE:

Use only where SAE 75W-90, API GL-4, API GL-5, or MIL-L-2105D gear oil is permitted.

The listed standards do not make this lubricant suitable for every gearbox, transfer case, or differential. Verify the required viscosity, GL classification, synchronizer requirements, differential type, oil capacity, and service interval before use.

This product is designed for compatible hypoid differentials without limited-slip systems. Use a dedicated limited-slip gear oil where LSD friction characteristics are required.

Some synchronized manual transmissions require a proprietary fluid, lower-viscosity lubricant, or dedicated synchromesh oil. Confirm the exact manufacturer specification before filling.

Do not use in automatic transmissions, continuously variable transmissions, dual-clutch transmissions, or systems requiring ATF.

IMPORTANT NOTES:

Follow the transmission or differential manufacturer’s specified drain interval and adjust it for racing, high temperatures, shock loading, towing, water exposure, or severe service.

A complete drain and refill is preferred when changing from another lubricant type.

Fill only to the manufacturer’s specified level. Incorrect fluid level can cause overheating, foaming, leakage, shifting problems, or drivetrain damage.

Use clean pumps, hoses, and dispensing equipment to prevent contamination.

Store the pail tightly closed in a clean, dry location protected from moisture, dirt, and extreme temperatures.
