McLaren has signed a technical partnership with Brazilian oil company Petrobras ahead of the 2018 season with the aim of using the company's fuel and oil products from 2019 onwards.
McLaren secured a deal with BP Castrol last year and will continue to use their products this season while Petrobras develops its new fuel and oil. Petrobras branding will be displayed on the car and a trackside laboratory will be set up in McLaren's garage.
"Brazil's passion for Formula One is legendary and the country has produced some of the most iconic names in Formula One history," McLaren CEO Zak Brown said.
