Castrol is a British global brand of industrial and automotive lubricants offering a wide range of oils, greases and similar products for most lubrication applications. The Wakefield Oil Company was founded by Charles Cheers Wakefield in 1899. The brand "Castrol" originated after researchers added castor oil to their lubricant formulations. In 1966, Castrol was acquired by company Burmah Oil, which was renamed Burmah-Castrol. Burmah-Castrol was purchased by London-based multinational BP in 2000.
The brand has been involved in Formula One for many years, supplying to a number of teams, including McLaren (1979–1980 and 2017–present), Williams (1997–2005), Team Lotus (1992–1993), Brabham (1983–1984), Jaguar (2000–2004), Renault (2017–present) and Walter Wolf Racing.
Castrol has sponsored the Ford World Rally Team and M-Sport in the World Rally Championship since 2003, and the Chip Ganassi Racing Ford GT factory team from 2016 to 2019. It has also sponsored Volkswagen Motorsport activities in the Dakar Rally and later the World Rally Championship since 2005.
Toyota Motorsport GmbH had Castrol sponsorship in the World Rally Championship from 1993 to 1998, and Hyundai Motorsport did so from 2000 to 2002. In North America, Castrol has been an active sponsor of NHRA drag racing. Castrol sponsored John Force Racing under the GTX brand from 1987 until the end of the 2014 season. Also, the All American Racers had Castrol sponsorship in the CART World Series from 1996 to 1999.
