While each specialist company has its own reason for getting into the classic car oil business, one of interest is Classic Car Motor Oil. The development of this product was driven by the Indiana Region of the Classic Car Club of America. Club members approached the D-A Lubricant Company near Indianapolis about the problems of modern oil in classic cars, and D-A worked with them to develop and co-market a specific blend of oil for Classics. Classic Car Motor Oil is now available in sizes from the quart to the case to the 55-gallon drum for enthusiasts with classic cars. The work from this club and this company show that grassroots efforts can yield great results.
