Inherently with many rotary engines, the entirety of the rotor and housing are not being sufficiently lubricated, resulting in premature wear or damage. We Recommend 1/2 oz per gallon of gas assuming you have a functioning oil metering system. If not, then we recommend 1 oz per gallon. For boosted engines about 2 oz per gallon is recommended.

Idemitsu Racing Rotary Premix

Engineered specifically to provide additional protection for high-performance rotary engines. Provides additional wear protection for apex seals and side seals, reduces deposits and keeps fuel injectors clean.

  • A special blend of base oils reduces deposits and subsequent exhaust port clogging. As a result, your rotary engine will maintain the power at which it was designed
  • Special detergent/dispersant additives keep your fuel injectors clean to reduce maintenance
  • Provides additional lubrication for apex and side seals to increase seal life and increase the efficiency of your engine
  • Special additives allow for better sealing of the chamber, creating greater efficiency and more power
  • Idemitsu Lubricants America Corporation recommends the use of the Ratio Rite Measuring cup to ensure a proper mixture of Premix Rotary Fuel Lube and gasoline

Note! Do NOT use with ethanol or ethanol based racing fuels! Normal 5-10% alcohol you get at the pumps is fine.
