As the largest Japanese lubricant manufacturer,
Idemitsu Kosan Co., Ltd. has supplied Japan's lubricant needs since
1911. With over 40% market share of Japanese automotive OEM (Original
Equipment Manufacturers) engine oil and lubricant supply, Idemitsu
has the knowledge, experience, and technical expertise to design
engine oils and other lubricants to specifically meet the unique
requirements of Japanese makes and models of automobiles. This expertise
was exhibited as Idemitsu developed the engine oil for the 1991
LeMans winning Mazda 787B! This was a crowning moment for Mazda,
Rotary Engines, and Idemitsu alike.
After supplying to OEM's in the United
States for over 20 years, Idemitsu has introduced its quality and
brand to the U.S. aftermarket by launching three new rotary engine
oils in July, 2004: Synthetic Rotary Engine Oil 10W-30, 20W-50,
and Synthetic Blend Rotary Premix oil. Benefits of these products
include extended bearing, apex seal, and turbocharger life.
As Volker Weidler, Johnny Herbert,
and Bertrand Gachot, drivers of Mazdaspeed Co Ltd's Mazda 787B,
awaited the start of the 1991 24 Hour LeMans race, Idemitsu engineers
were standing by, arguably as nervous as the drivers. Idemitsu had
spent years developing the technology behind the engine oil used
in the 787B and were hoping for a problem free fast race by the
250,000 people gathered on June 22,
1991 to watch the historic 24 Hour LeMans race, and 250,000 people
weren't disappointed. They were witness to the first rotary engine
driven winner in the history of LeMans. Weidler, Herbert, Gachot,
and the Idemitsu engineers could now relax and celebrate the winů
The 4708cc 787B finished the race by
completing 2 (362 in total) more laps than the closest competitor.
The 787B covered a total of 4,923 kilometers (3,059 miles) at an
average speed of 205 km/hr (127 mi/hr). For those few who doubted
the rotary engine's capability, no doubt could exist any longer.
Idemitsu Racing Rotary Engine Oil 10W-30 and
(Full Synthetic) $7.50 a quart / $84.95 a case of 12qts. (better value!)
- Formulated Specifically For High Performance
- Contains Special Molybdenum Agents to Reduce
Friction, Which Increases Horsepower & Torque
- Improved Sealing Performance of the chamber,
facilitating more power generation
- Minimizes Exhaust Port Clogging
- Superior Shear Stability
- Exceptional Wear Protection & Durability
to protect main bearing and eccentric shaft
- Extends the life of turbochargers by reducing
- Contains special molybdenum agents to reduce
friction, which increases horsepower & torque
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
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.
