Militec-1 (made in USA) is sold in Brazil in 200ml bottles as a metal conditioner. It should be added to the engine oil, 200ml for every 4 liters, and should work for 20,000km. It is said to reduce emissions and fuel consumption, and improve engine performance with less internal friction, wear and corrosion. Everything except regrowing hair! I searched the forum and this product is only mentioned as a lubricant for knives and guns, used in grease form. I confess I have used it before, on my Kawasaki Z750. CanĀ“t say much about mileage improvement or long term benefits or shortfalls, since I sold the bike long ago, but I can tell you that the engine would sound and feel much happier, with a mellower exhaust note and revving easier, right after the first use. Trying to collect some intel before using it on my GS.
Oil additives are snake oil as far as I know. If something were so miraculous, you'd think the large oil companies would already be utilizing them. Save your money...
