Recommended PreMix Ratios
50-80cc (24-32:1) | 125cc (24-40:1) | 250cc (24-40:1) | 500cc and up (32-60:1)
Caution!
Not intended for use in oil injection systems.
When blending with alcohol it normally requires more oil.
Care must be exercised when blending with low specific gravity (below 0.730) race
gasoline or aviation fuels and in temperatures below 35ºF as separation may occur.
Separation may also occur in alcohol containing a high percentage of nitromethane.
Check before using.
Usage
Castor 927 is ideally suited as a premix for both leaded and unleaded fuels.

Castor 927 is a unique blend of highly refined castor oil, a specially prepared synthetic
and an additive system that reduces carbon and gum formation and provides excellent
rust & corrosion protection.
Castor 927 also contains an exclusive additive that keeps power valves cleaner and
working properly.
For all of us that wish to keep our air and water cleaner, Castor 927 is biodegradable.
Castor 927 keeps on lubricating; where other lubricants turn to carbon or vaporize, and
provides extra protection on cylinder walls, bearing journals and other critical areas
at temperatures much higher than other lubricants.
