NASCAR owner-driver Tony Stewart announced Tuesday that his No. 14 Chevrolet will begin carrying Mobil 1 as a co-primary sponsor in the 2011 Sprint Cup Series season.
The multi-year deal will put Mobil 1 on the hood of the two-time Cup champ Stewart's Chevy for 11 races and it will serve as associate sponsor for the other 25 races that co-sponsor Office Depot will headline for the team.
ExxonMobil will also provide engineering support to Stewart-Haas Racing and Mobil 1 will be an associate sponsor on the team's second car, the No. 39 Chevy driven by Ryan Newman.
"As a team owner, I'm absolutely thrilled to add such a respected technology partner to our race team,'' Stewart said two days after collecting his second win of the Sprint Cup season in Fontana, Calif.
"And as a driver, it's exciting to partner with a brand that has such an incredible racing pedigree.''
Mobil 1 is completing the last year of its sponsorship on Penske Racing's No. 77 Dodge driven by former Indy 500 winner Sam Hornish Jr. It is the "Official Motor Oil of NASCAR.'' It replaces longtime Stewart sponsor Old Spice, which announced earlier this season it would not be renewing its sponsor contract.
