Wakefield had previously left a job at Vacuum Oil to start a new business selling lubricants for trains and heavy machinery.

The reciprocation of this caused a lever on the lubricator to oscillate, and this was converted to a small rotary movement by a ratchet.

The gradual rotation caused a small amount of lubricating oil to be fed into pipes leading to the cylinders, valves and other parts.

Audi Sport's activities in rallying and touring car racing have been sponsored by Castrol, as well as its Le Mans Prototypes program since 2011.

[11] In the All-Japan Grand Touring Championship, the 1997 championship-winning TOM'S Toyota Supra[12] (famous from the Gran Turismo series by Polyphony Digital) and later the Mugen Honda NSX had Castrol sponsorships.

In 2014, Castrol sponsored former Indy 500-winning IndyCar team Bryan Herta Autosport, with English rookie Jack Hawksworth behind the wheel.

The same was true for an International Rally held in South Africa, ending annually in neighbouring Swaziland.

Later only some competitors' cars were carrying the bright green and red colours of Castrol sponsorship in national rally events, notably the S.A. Toyota dealer team.

In 2019, Castrol extended their sponsorship activities by re-forming a partnership with Jaguar, this time supporting them in Formula E[17] and also NASCAR Cup Series giants RFK Racing-Ford since 2020 season due to Ford's commercial relationship with BP plc.

In 2011, Castrol's Edge brand became the official motor oil sponsor for the league, renewed until the 2017 season.

"[27][28] For many years, the opening notes of the second Nachtmusik movement of Mahler's Seventh Symphony were used as the signature theme of Castrol TV commercials.

[29] Wakefield vehicles advertised the company and Castrol on their sides; models of them were made by Dinky Toys, and in later times became sought-after collectors' items.
