HEL Performance Braided Clutch Line Kit RX-7 FC 85-91

The Idemitsu Racing Rotary Fuel Lube Premix is added to the gasoline fuel.
The full synthetic Idemitsu Racing Rotary Fuel Lube Premix provides additional lubrication for apex and side seals, which extends the life of the seals and increases the efficiency of the rotary engine.

In addition, allow special additives adapted to rotary engines better sealing of the chambers, causing the engine runs noticeably quieter and thus more power can unfolded.
A formulation of synthetic base oils reduces all deposits and carbonization at the engine outlet.
Dispersive additives keep clean the injectors and reduce wear to a minimum. Proven mixing ratio ranges are 1:100 - 1:150 for racing and 1:200 - 1:300 for daily drive.
For an optimal mixing, fill in the premix oil before refueling.

Idemitsu Rotary Engine Oil 20W50
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.

Do you feel that you aren’t getting the power you should be from your rotary engine?  Are you experiencing bearing wear under severe (or possibly under not-so-severe) operating conditions?  If so. you may be using the wrong engine oil.  Idemitsu Racing Rotary Engine
