Maxima Castor 927 Racing Premix two-stroke oil — 1L race-grade castor + ester formula for max power

Maxima Castor 927 Racing Premix is a high-performance two-stroke racing oil formulated from refined castor and exotic esters to deliver maximum power, durable film strength, and race-grade protection for aggressive engines.

Designed for racers and performance enthusiasts who demand consistent oiling, reduced wear, and easy throttle response, Castor 927 blends traditional castor oil advantages with modern ester technology. The result is a premix oil that sustains a durable lubricating film under extreme loads while promoting clean-running combustion and reliable power delivery.

How does Castor 927 help protect high-revving race engines?

Castor 927 creates a resilient lubricating layer that resists shearing at high rpm and under heavy load. Its surface-active chemistry adheres to metal, reducing metal-to-metal contact and helping components survive rigorous race conditions.

• Exotic esters boost film strength for extreme temperatures and rev ranges
• Highly-refined castor oil maintains consistent viscosity under load
• Surface-active agents cling to critical engine surfaces for ongoing protection

Will this premix improve power output and throttle response?

The formulation is optimized to minimize drag while ensuring lubrication, which supports crisper throttle response and efficient power transfer. Many independent surveys rate Castor 927 as a top choice for riders seeking peak engine performance without sacrificing protection.

• Low-resistance base for cleaner combustion and reduced deposits
• Esters designed to permit maximum power output at race settings
• Balanced blend prevents bogging while protecting bearings and pistons

How should I mix and use this premix for best results?

Castor 927 is supplied as a premix-ready oil for two-stroke applications—measure and blend according to your engine manufacturer’s recommended ratio. For racing conditions, follow team or builder guidance for richer protection ratios; always mix thoroughly before fueling.

• Use manufacturer or tuner-specified oil-to-fuel ratios for race tuning
• Mix thoroughly to ensure uniform lubrication throughout the fuel
• Store sealed and upright away from heat and direct sunlight

What maintenance benefits will I see over regular two-stroke oils?

The unique combination of refined castor and exotic esters helps keep combustion chambers and exhaust ports cleaner while preserving oil film thickness where it matters most. Riders report extended component life under race use and fewer deposit-related issues compared with untreated fuels.

• Surface-active chemistry helps shed harmful deposits from metal surfaces
• Maintains oil film in extreme conditions to reduce wear and scoring
• Trusted by racers and rated #1 in multiple independent surveys

Who is this for: Castor 927 Racing Premix is crafted for professional racers, track-day enthusiasts, and performance builders who run two-stroke engines under aggressive conditions. If you need a premix oil that marries the time-proven film strength of castor oil with modern ester chemistry for reliable protection and peak power, this product is built for you.
