Motul Oil

Why Choose Motul for Motorsport?

Motul has been at the forefront of synthetic lubricants since introducing the world's first multigrade oil in 1953. Their motorsport range is developed through technical partnerships with WRC teams, Le Mans winners, and professional rally crews, and their Ester Core technology delivers measurably better film strength, lower friction, and greater thermal stability than conventional synthetics.

We stock over 40 Motul products covering engine oil, gearbox oil, differential fluid, brake fluid, and coolant. Whether you're running a Rally4 car, a track day build, or a classic rally project, our team can recommend the right product for your engine, gearbox, and braking system.

Motul 300V: The Racing Engine Oil

The 300V is Motul's flagship competition engine oil, built on Ester Core technology and the choice of professional rally and circuit teams running sustained high-temperature, high-rpm conditions. Ester-based oils form a stronger bond with metal surfaces, so the oil film holds together when temperatures spike on a hard stage. This means less wear, more consistent oil pressure, and a measurable step up from conventional synthetics.

We stock the most popular 300V viscosities for motorsport:

• 300V 15W-50 Competition

• 300V 5W-40 Power

• 300V 5W-30 Power Racing

• 300V 10W-40 Factory Line

Motul Gear and Differential Oils

Gearbox and differential oil is one of the most overlooked fluids in motorsport preparation, and the wrong choice can cost you a gearbox on a rally stage. Motul's competition gear oils are formulated for the extreme shear loads and heat generated by sequential gearboxes, dog engagement, and limited slip differentials.

• GEAR Competition 75W140: our best-selling Motul product; the go-to for sequential gearboxes and LSDs in rally cars operating under heavy loads and shock

• GEAR 300 75W90: fully synthetic for gearboxes and differentials where a lighter viscosity is specified; popular for road-going performance cars and lighter competition applications

• GEAR 300 LS 75W90: specifically formulated for limited slip differentials, preventing the grabbing and noise that standard gear oils can cause in LSD units

• 90 PA Limited Slip Differential Fluid: Motul's dedicated LSD fluid for rally and racing; meets API GL4/GL5 specifications

Motul Racing Brake Fluid

Under hard braking on a rally stage, brake fluid temperatures can exceed the boiling point of standard DOT 4, causing fade and a spongy pedal. Motul's RBF range is built to resist this.

• RBF 660: excellent value for track days and club-level competition; higher dry boiling point than standard DOT 4, reliable under repeated hard braking

• RBF 700: the step up for professional competition; higher boiling point than the 660, designed for endurance racing and multi-stage events where sustained brake temperatures are extreme

Both are available in 500ml bottles and are compatible with all DOT 4 systems.

Motul Coolant and Car Care Products

We also stock Motul Autocool Optimal antifreeze (ready to use, protecting to -37°C) and Motocool Factory Line coolant for motorcycle and small-engine applications. The Car Care range includes wheel cleaner, plastic cleaner, express shine, and odour neutraliser.

Frequently Asked Questions

Is Motul a good oil brand?

Motul is one of the oldest and most respected lubricant brands in motorsport, with a history stretching back to 1853. Their 300V Ester Core range is used by professional WRC, Le Mans, and Formula teams, and Motul consistently ranks alongside the biggest names in lubricants as a top choice among professional racing crews.

What is the difference between Motul 300V and regular Motul oil?

The 300V uses Ester Core technology, which is a synthetic base stock that forms a stronger chemical bond with metal surfaces. Standard Motul oils like the 5100 or 3100 ranges use conventional synthetic or semi-synthetic base stocks. In practice, 300V offers better thermal stability, lower friction, and stronger film strength under extreme conditions, making it the right choice for competition engines.

Which Motul gear oil should I use for a sequential gearbox?

GEAR Competition 75W140 is the one to use. It’s formulated specifically for the high shear loads and shock conditions that sequential boxes generate. If your gearbox manufacturer specifies a lighter viscosity, GEAR 300 75W90 is the alternative. For limited slip differentials, go for GEAR 300 LS 75W90 or the dedicated 90 PA LSD fluid depending on your application, and always refer to your gearbox manufacturer recommendations.
