Formula One team Renault are ditching their French fuel supplier in favour of BP and its Castrol brand.
The energy giant will take over from Total as the constructor’s official fuel and lubricant supplier this season.
The two companies last worked together in 1997 when then-world champions Williams had Renault engines and BP sponsorship.
Renault Sport managing director Cyril Abiteboul said new regulations in the hi-octane sport will make elements such as fuel and lubricants potenital game changers.
He said: “With the new aerodynamic regulations for the 2017 Formula One season, power sensitivity will increase.
“Therefore fuels and lubricants will make an even greater difference to the overall performance of the car than they have since the new power unit regulations have been introduced in 2014.”
Renault were crowned champions in 2005 and 2006 with Spainiard Fernando Alonso at the wheel.
They sold their factor team in 2010 to Lotus but continued to supply parts including the Renault chassis.
Renault returned as constructors last year, finishing ninth of 11 teams.
The F1 team hope to improve their standing this year with an improved engine and German driver Nico Hulkenberg alongside the UK’s Jolyon Palmer.
The fuel supply announcement continues a shake-up that started in December when ExxonMobil ended a 21-year partnership with McLaren and switched to Red Bull, who use
Renault engines with Tag Heuer branding.
Former world champions Red Bull were also previously fuelled by Total.
Honda-powered McLaren have yet to announce their new fuel supplier but are also expected to do a deal with BP.
Mercedes are partnered with Petronas while Ferrari’s iconic brand marriage to Shell has been on the go for decades.
