Red Bull Racing has confirmed its switch to fuel and lubricant supplier ExxonMobil for the start of the 2017 Formula 1 season.
Red Bull had been using fuel and oil from Renault's partner Total, but will switch to ExxonMobil next year despite continuing to run with the French engines.
"Mobil 1 and Red Bull Racing are two global brands that share a passion for racing, performance and innovation," said team boss Christian Horner.
"Mobil 1 has been an iconic brand in Formula 1 for more than 30 years and our new partnership provides us with a unique opportunity to tap into ExxonMobil’s world class expertise."
"In addition to welcoming ExxonMobil to the Red Bull Racing stable, I would like to extend my thanks and appreciation to the technical team at Total, who have made a valuable contribution to our success in Formula 1 during our partnership."
ExxonMobil has been involved in Formula 1 for 31 years, having supplied fuel and lubricants to over 100 race-winning cars.
