Maxima Castor 927 Racing Premix 2-Stroke Oil — Ester-Boosted Castor, Ash-Free Protection

Maxima Castor 927 Racing Premix is a castor-based, ester-boosted 2-stroke oil engineered to deliver peak performance and robust protection under extreme racing conditions.

Built from a refined castor backbone blended with exotic esters and an ash-free additive package, this premix lubricant resists carbon buildup and vaporization while maintaining a durable lubricating film on critical engine surfaces. The formulation emphasizes surface adhesion and tenacity to protect cylinder walls, bearings and other high-stress components without leaving gum or ash deposits. Riders and tuners choose it where maximum power and clean operation matter most.

How does this oil improve power and throttle response?

The ester-enhanced castor matrix reduces friction and sustains a consistent oil film at high temperatures, helping the engine run smoother at wide-open throttle. Because the chemistry is designed to resist vaporization, it keeps lubrication where it’s needed during peak loads.

• Exotic esters boost film strength for consistent protection under load
• Highly refined castor oil maintains viscosity at elevated temperatures
• Low vaporization rate prevents loss of lubricity at high RPM

Will this premix keep my engine clean and free of deposits?

Yes — the ash-free proprietary additives minimize gum, ash and corrosive residues that can foul ports and combustion chambers. The surface-active components actively cling to metal, preventing sticky deposits and helping maintain long-term engine cleanliness.

• Ash-free formula reduces combustion deposits and spark plug fouling
• Surface-active chemistry adheres to walls for continuous protection
• Resists carbonization even in severe operating cycles

What protection does it offer for bearings, journals and cylinders?

Castor 927 forms a tenacious lubricating layer that cushions metal-on-metal contact during high-load events, reducing wear on journals, bearings and cylinder walls. This consistent film strength helps preserve component geometry and extends service intervals in aggressive riding scenarios.

• Strong film tenacity protects against scuffing and scoring
• Adhesive ester chemistry maintains coverage during transient conditions
• Optimized for racing loads and repeated thermal cycling

How should I use this premix and what mixing ratios are typical?

Castor 927 is supplied as a premix oil intended to be blended with gasoline before filling the fuel tank, following your engine manufacturer or tuner’s recommended ratio. Ratios vary by application and performance goals — use the established fuel-to-oil mix recommended for your machine or consult a tuner for race setups.

• Mix with gasoline according to your engine’s spec or tuner guidance
• Suitable for high-performance two-stroke motorcycles, off-road bikes and racing applications
• Store sealed and shake before pouring to ensure uniform additives distribution

Who is this for? Maxima Castor 927 Racing Premix is aimed at racers, performance-minded riders and engine builders who demand maximum power, dependable lubrication under extreme heat and aggressive protection against deposits. If you run high-RPM, high-load two-stroke engines or participate in competitive motocross, road racing or vintage racing where castor-based oils are preferred, this formulation offers the specialized chemistry needed for peak performance without compromising engine cleanliness.
