Idemitsu Racing Rotary Engine Oil 20W-50 (Full Synthetic)

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.
