Maxima Castor 927 Premix is a high-performance, castor-based, ester-fortified 2-stroke engine oil developed for premix applications in high-output gasoline engines. It is engineered to deliver exceptional film strength, consistent lubrication, and superior protection in extreme racing and high-temperature operating conditions.
This premium premix oil combines highly refined castor oil with advanced surface-active ester technology that bonds to critical engine components, providing outstanding anti-wear and anti-scuff protection under high RPM and heavy load. Its vaporization-resistant formulation helps maintain lubrication integrity while reducing power loss and metal-to-metal contact.
Castor 927 features an ashless additive system designed to minimize deposits, prevent corrosion, and reduce the formation of gums and varnish. The formula promotes clean engine operation while preserving the lubricity benefits of castor oil. It is safe for use at any OEM-recommended premix ratio and is intended for carbureted 2-stroke engines used in racing and aggressive performance applications.
