From Stuart: How I originally heard about Diamond Nano-Lube by Bestline Racing, LLC. I had my aircraft engine rebuilt and my rebuilder told me to run 1 bottle of Bestline Engine Treatment per change. He did the initial break-in using Bestline and Mineral oil. We also ran our own test on an old S60 (T5) Volvo just to see if the claims were true. I did an oil change but used two bottles of Engine treatment, ran the car for about 400 miles. I then drained the oil, added 1 quart of Castrol oil GTX and made a 200-mile round trip. The car ran great no issues at all. I changed the oil added my bottle of engine treatment and gave the car to one of my sons. Love this stuff! I use it in everything I own.
