As per your demo with Maxilube Antifriction Metal Treatment against Slick 50, which I have used for many years, there is no comparison. My wife and I are full time drivers. I have a 1 ton Chevy truck with a 454 pulling a 40 foot 5th wheel, with a weight of 15,000 lbs. I have been getting 10 mpg loaded or empty. I put 16 ounces of Maxilube to a 8 quart crankcase warmed up. Within minutes I notices a quieter running unit on a full tank of fuel (92 Octane). I drove 300 miles, filled the tank again and noticed an increase of 2 mpg using Maxilube. I will continue to use this product and strongly recommend it to others.
