MOTUL 300V COMPETITION 15W-50 Racing Engine Oil

Purpose and Specifications

MOTUL 300V COMPETITION 15W-50 is a 100% synthetic racing engine oil designed for high-performance motorsports engines. Built on ESTER Core technology, this oil delivers maximum power output while maintaining exceptional engine protection under extreme racing conditions.

Key Performance Benefits:

• Fast Oil Pressure: The 15W-50 viscosity grade ensures rapid oil circulation at engine startup, establishing pressure quickly even in cold conditions
• High-Temperature Stability: Maintains thick, protective oil film at extreme temperatures, reducing engine wear during sustained high-rpm racing
• Reduced Internal Friction: Friction modifiers lower engine operating temperature and unlock additional horsepower
• Fuel Dilution Resistance: Compensates for unburned fuel entering the oil, keeping pressure stable during endurance events
• Low Oil Consumption: Advanced synthetic formulation minimizes evaporation, reducing top-ups between races
• Shear Stability: Oil maintains consistent viscosity under extreme stress, protecting against pressure drops

Ideal Applications: Endurance racing, rally, GT racing, historic/rebuilt racing engines, naturally aspirated or turbocharged gasoline and diesel engines with direct or indirect fuel injection.

When to Use / Replace?

Oil Change Intervals: Consult your tuning service partner for the appropriate drain interval, as racing conditions vary significantly. Typical racing engines may require oil changes every 5-10 hours of track time or per race event, depending on engine modifications and fuel type.

Operating Temperature Range: This oil performs reliably from -39°C (-38°F) at startup to 238°C (460°F) flash point, covering extreme racing scenarios.

Storage: The high ester content provides excellent protection during extended storage periods, with the oil clinging to metal surfaces to reduce cold-start wear when the engine sits for months.

Important: Do not mix with other synthetic or mineral oils. Use only MOTUL 300V COMPETITION 15W-50 for optimal performance. Suitable for alcohol-based racing fuels with shortened drain intervals.

Frequently Asked Questions

Q: Can I use this oil in street cars?
A: While technically possible, MOTUL 300V COMPETITION 15W-50 is engineered specifically for racing engines operating at extreme temperatures and rpm. Street cars do not require this level of performance and would not justify the premium cost. Use MOTUL road racing oils for street applications.

Q: Why is 15W-50 better than other viscosity grades for racing?
A: The 15W rating ensures fast oil flow at cold startup, preventing engine damage before pressure builds. The 50-weight rating maintains a thick protective film at high temperatures and high rpm, critical for race-prepared engines. This balance is ideal for endurance racing and rebuilt classic engines.

Q: How often should I check the oil level during racing?
A: Check oil level before each race session and after extended track time. The low volatility of this synthetic formulation minimizes consumption, but unburned fuel dilution during racing can affect levels. Top up only with the same MOTUL 300V COMPETITION 15W-50 oil.
