|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. For decades, this expertise has been proven time and again on the race track.|
After supplying to OEM's in the United States for over 20 years, Idemitsu is proud to introduce its quality racing formulas to the U.S. aftermarket by launching three new rotary engine oils and a full-line of piston-type engine oils. These customized lines of premium lubricants offer both classes of engines benefits that include but are not limited to better durability and increased horsepower.
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 Mazdaspeed team.
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 win.
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.

What the Experts are saying:
Once again, I would like to thank IDEMITSU for providing us a product that is outstanding. Serious engine builders and tuners now have IDEMITSU lubricants that can withstand extreme torture and stress without adding costly additives and stabilizers.
Moving from All Motor to Modified in the NHRA Sport Compact Drag Racing Series, I have had to develop considerably more power (From just over 300 RWHP to close to 1,000 RWHP) with the same 13B engine and the addition of a turbo charger. The results from the R&D, testing and racing we have completed to date have proved beyond our shadow of a doubt that your lubricants ?an take the heatĚ
I am amazed that each time we inspect our engines & turbo chargers; we have no wear at all associated with the lubricated components. This peace of mind permits this team to race with confidence as was the case with our first Modified win August 21, 2005 at Moroso Motorsports Park.
Thank you IDEMITSU for providing us Off the Shelf lubricants that meet and exceed our expectations.
