Purpose and Specifications

MOTUL 300V Competition 15W50 is a premium 100% synthetic ester-based racing engine oil designed for high-performance motorsports. This 60L drum delivers powerhouse protection for naturally aspirated, turbocharged, or supercharged gasoline and diesel racing engines, including endurance racers, rally cars, GT vehicles, and historic rebuilt engines.

Key practical benefits include:

• Maximum power boost: Reduces internal friction for quicker revs and higher torque across all RPMs.
• Rock-solid reliability: Holds high oil pressure stable up to extreme operating temperatures over 120°C, preventing wear even in prolonged races.
• Superior protection: Ester technology clings to metal parts for unbeatable film strength, cutting engine wear by resisting breakdown under severe loads.
• Low oil use: Minimizes evaporation and consumption during hot, high-RPM track sessions.
• Clean operation: Strong detergents keep engines spotless, reducing noise and improving drivability.

Perfect for tuned engines running biofuels like Ethanol up to E85, with fast cold starts down to -30°C and consistent flow in brutal heat.

When to Use / Replace?

Use this oil in race-prepared engines facing wide RPM ranges and punishing conditions, like 24-hour endurance events or high-rev rally stages. Ideal when you need oil that fights fuel dilution from unburned fuel while maintaining pressure.

Replace every 3,000-5,000 km or after 3-6 months of racing use, or sooner with alcohol fuels—consult your tuner for exact intervals based on track time. Shelf life is 5 years unopened in cool, dry storage.
