The official motor oil for the NBA is expanding its alliance with the league, signed in 2016, by inking multi-year pacts with three teams — the Boston Celtics, Charlotte Hornets (which will host the 2019 All-Star Game) and Houston Rockets. The last deal includes the Toyota Center and multi-media marketing support at the local level, as well as a national sweepstakes offering tickets to the 2018 NBA Finals.
