Maxima Castor 927 Oil
This is for use on PW50's or PW80's and 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.
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. Recommended Premix Ratio 50-80cc (24-32:1)
Available in 2 sizes, 1 Liter (33.8 fl oz) for $19.99 or 1 Pint (16 fl oz) for $10.99

PW50 Oil Injector Block Off Plug
One of the best performance upgrades for the PW50 is installing our oil block off plug. Pre-mixing your oil and gasoline will eliminate the standard oil pump assembly. The oil pump is not accurate most of the time, sending either too much or not enough oil into the engine causing big performance loss. Even worse, an oil-deprived engine will result in premature wear or in many cases extreme engine failure. Eliminate the risk and gain performance - install our Oil Block Off Plate.
*We recommend using pre-mix Super unleaded quality gasoline at 40:1 ratio with Maxima brand "Super M" premix oil.
