Motul 300V Factory Line 10W-40 Synthetic Racing Motor Oil 4L — ESTER Core®, High RPM Protection

Engineered from motorsport experience, Motul 300V Factory Line 10W-40 combines high-performance synthetic esters with advanced additive chemistry to reduce friction, preserve oil film strength at high temperatures, and resist shear in demanding four-stroke motorcycle engines. Approved to JASO MA2 and API SN standards, this formulation suits street and track use where wet-clutch compatibility, quick throttle response, and consistent performance across race weekends matter most.

How does Motul 300V improve acceleration and horsepower?

The ESTER Core® base creates a polar molecular bond with metal surfaces that lowers internal friction, allowing the engine to operate more efficiently and release otherwise trapped horsepower. Riders often notice sharper throttle response and stronger acceleration without engine modification.

• ESTER Core® esters reduce boundary friction at contact points
• Stable viscosity under heat preserves oil film for consistent power
• Formulation optimized for high-RPM performance and quick throttle recovery

Will this oil protect my engine and gearbox during a race?

Yes — the 300V Factory Line 10W-40 is designed to maintain thick, protective oil films at elevated temperatures and under high shear, decreasing wear on bearings, cams, and transmission components commonly stressed in racing. Its shear stability helps preserve viscosity and protective properties throughout hard sessions.

• High film strength to resist breakdown under pressure
• Excellent shear resistance retains viscosity after repeated high-load exposures
• Compatible with integrated gearboxes and wet clutch systems for full drivetrain protection

How does this oil affect shifting and clutch feel?

Formulated specifically for modern sportbikes, Motul 300V promotes smooth, precise gear changes and dependable clutch engagement with minimal drag. The chemistry balances clutch slip control with low friction for confident, consistent shifting on both street and track.

• JASO MA2-rated for wet-clutch performance and positive engagement
• Reduced friction yields crisper, more consistent shifts
• Suitable for bikes with or without catalytic converters

How should I use and change Motul 300V for best results?

For peak performance, follow your motorcycle manufacturer's recommended service intervals and consider oil changes after each race or intensive track day. Use the correct 10W-40 viscosity for your machine, ensure proper filter replacement, and warm the engine to operating temperature before hard riding.

• Recommended for high-revving four-stroke motorcycles under racing loads
• Change interval: per OEM guidance or after race events for maximum protection
• Use with compatible filters and confirm JASO MA2/API SN compliance for best results

Who is this for? Motul 300V Factory Line 10W-40 is aimed at racers, track-day enthusiasts, and sportbike riders who demand race-proven lubrication and consistent performance at the limit. If you run a high-output four-stroke motorcycle—air- or liquid-cooled—with integrated gearbox and wet-clutch requirements, and you want an oil tailored to sustain peak power, sharp throttle response, and reliable protection under extreme conditions, this formulation is built for you.
