Best Stuff For Your Rotary
I’ve ran this in my 2004 Rx-8 for three years now with no issues. Definitely much better than a Lucas 2 stroke premix you can get at any auto part store. This stuff is much thicker.

Information
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.
