PennGrade is a multi-year, major associate sponsor of Rahal Letterman Lanigan (RLL) Racing in the Verizon IndyCar Series.
This partnership marks a return to Indy car racing for PennGrade's parent company D-A Lubricant Co., based in Lebanon, IN, who sponsored entries in the Indianapolis 500 from 1955 – 1958 with a highest finish of sixth in “The Greatest Spectacle in Racing” in 1956 with driver Bob Sweikert. D-A-sponsored cars also ran in the USAC Championship Car series during that time period, earning one win in 1957 and four wins in 1958.
In addition, the relationship provides a business-to-business opportunity with the LANCO Group of Companies, whose president is RLL co-owner Michael Lanigan.
In the 2015 Verizon IndyCar Series season, RLL driver Graham Rahal scored two wins and contended for the series championship as the fastest Honda-powered entry.
Looking forward to 2016, PennGrade will be involved with RLL IndyCar entry driven by Graham Rahal.
