Maxima Castor 927 Motor Oil

Maxima Castor 927 2T Motor Oil is a unique blend of highly refined castor oil with a specially prepared synthetic and an additive system that reduces carbon and gum formation and provides excellent rustand 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) / 125cc (24-40:1) / 250cc (24-40:1) / 500cc and up (32-60:1)


  • Ultimate lubricant for 2-cycle racing engines
  • The most biodegradable 2-cycle oil available
  • New additive keeps power valves and rings even cleaner

Note: Pre-mix only, not for injection systems.

Maxima Castor 927 Engine Oil 5 5 3 3
Excellent Oil Castor oil is still the standard by which all other petroleum and synthetic oils are judged. I've used 927 in every type of two-stroke application possible and at every mix ratio possible. By far, it is my favorite oil and the smell is classic two stroke. If castor isn't your thing, check out SuperM - I've gone through a few dozen gallons of that stuff too, excellent oil. September 30, 2013
Its the best 2 stroke oil! Best 2 stroke oil I've ever used. For best results use with the Maxima octane booster and ngk iridium spark plugs. It'll completely transform your bike :) August 5, 2013
Excellent 1975 350 two stroke, always runs smooth, never fouls plugs. Low smoke & odor. September 14, 2011
