About 20 years ago at the Del Mar Fair in California there was a guy selling an oil additive. He had a machine that would spin a shaft against a couple of balls with the load controlled by a torque wrench. He would pour various oils into this cup, and press the balls against the shaft and show the force required to stop the spinning. Ordinary oils and other additives would stop at a couple of pounds of pressure, but his attitive would go up to 30 or 40 pounds, even with he removed the cup and let the shaft continue spinning... imagine that. I went back to the farm animal display and got a cup of my special attitive and he was floored to find that it worked just as well as his special stuff. I don't know what his 'stuff' was but mine was bleach. So, does that mean that bleach is a good additive?
