1. Place roast in a lightly greased 6-qt. slow cooker; pour barbecue sauce and cola over roast. Cover and cook on LOW 8 to 10 hours or until meat shreds easily with a fork.
2. Transfer pork to a cutting board; shred with two forks, removing any large pieces of fat. Skim fat from sauce, and stir in shredded pork.
Note: We tested with Cattleman's Original Barbecue Sauce.
