Long Island Truck Parts carries "truck pride" oil for very good prices- a little over $9/gal. I know I can get Delvac at wal-mart for $10/gal, but I hate wal-mart. Id rather give Truck Parts the business. But, does anyone know who makes this oil??? It's CJ-4 rated, but I cant find out who makes it, and they dont know. It's for fleet trucks and equipment that are very well maintained.
