Idemitsu Kosan Co., Ltd. is one of Japan's largest integrated energy and lubricants companies, founded in 1911. Through its US subsidiary, Idemitsu Lubricants America Corporation (Jeffersonville, IN), it manufactures the factory-fill transmission fluids, power steering fluids, and other specialty lubricants that ship inside many new Honda, Toyota, Subaru, Nissan, and Acura vehicles. Idemitsu's OEM supply contracts mean its consumer-branded products are often the same fluids that come from the factory, sold without the OEM badge. The brand covers automatic transmission fluids (ATF DW-1, CVT fluids), power steering fluid, and a range of motor oils.
