A Big Daddy custom chopper is taken through its paces testing Royal Purple synthetic oil. An infrared camera is used to record engine temperatures with and without synthetic oil. Royal Purple’s Max-Cycle synthetic oil registered less heat which translates to more horsepower.
Note: Improvements in performance depend on the vehicle, it’s condition and how it’s used. This video is not intended to imply that all users will experience the same performance gain by upgrading to Royal Purple.
