As the developer of the engine oil for the winning 1991 LeMans Mazda 787B and a long time supplier of vital lubricants to Mazda, Idemitsu has intimate knowledge of the requirements of rotary engines.

-With the precise base oil mix of PolyAlphaOlephins and PolyEsters, Idemitsu Rotary Engine Oils are able to minimize those deposits on your apex seals.
-Allows for better sealing of the chamber, facilitating more power generation.
-Extends the life of turbochargers by reducing bearing coking.
-Specially developed additives facilitate even tooth load on the front stationary gear to allow for higher loads and higher RPM.
-Premium anti-wear agents create a strong film between the main bearings and the eccentric shaft, reducing metal-to-metal contact and minimizing bearing wear.
-Developed to reduce entrained gas generation. Entrained gases reduce the oils ability to prevent metal-on-metal contact, thereby increasing main bearing wear.
-Includes Molybdenum as a friction modifier. This compound reacts with the metal surfaces to create a low-shear boundary. The low shear characteristic reduces friction, increasing efficiency and power output.
