Idemitsu Racing Rotary 20W-50

Engineered specifically to meet the unique requirements of high-performance rotary engines, including turbo and supercharged applications. Fully synthetic advanced Molybdenum formulation is optimized for performance, higher temperature protection, durability, reduces friction and minimizes deposits.

  • With the precise base oil mix of PolyAlphaOlephins and PolyEsters, Idemitsu Rotary Engine Oils are able to minimize 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-on-metal contact and minimizing bearing wear
  • Developed to reduce entrained gas generation. Entrained gases reduce the oil’s 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
