PennGrade Motor Oil, which of course serves as the presenting sponsor of the 100th running of the Indianapolis 500, has taken on a greater role with the RLL team this year, and will serve as primary sponsor on Rahal’s No. 15 Honda for Long Beach.
PennGrade is a brand of Lebanon, Ind.-based D-A Lubricant Co., which joined RLL last year.
"I’m thrilled to run the PennGrade Motor Oil livery in Long Beach," Rahal said. "The car is so cool looking, and for me it’s just going to be a lot of fun to get out there and drive it. PennGrade has been a tremendous partner of our team since last year and I am very excited to see what happens with the brand going forward."
