Ford Mustang Road Racing Buildup Royal Purple Oil

To combat the high temperatures in road racing, Crazy Horse drained the oil and power-steering fluid in order to replace them with Royal Purple XPR 5W30 and MAX EZ. The high film strength of the oil should do well to protect the bearings as the crank screams into the upper rpm range; meanwhile, the power-steering fluid would keep the steering rack quiet and fully operational. After draining the coolant and replacing it with an 80/20 mix for increased heat absorption, one bottle of Purple Ice was added for even greater protection.
