I would suggest you read ARP’s white paper on the subject of reproducible torque levels and how they cannot be achieved without proper lubrication. The random scatter of torque readings without lubricant demonstrates why ANY fastener with a torque setting needs to be correctly lubricated in order to achieve the desired clamping loads.
