ADDO?: novel additive for engine oils: ADDO is based on a mixture of Diamonds and Graphite nanoparticles. Very fine particles of NanoDiamond, with size of only 4 nm, polish the moving parts of an engine to mirror quality, leaving no defects. NanoDiamonds get impregnated into the metal surface converting it to the diamond-metal composite layer with high mechanical strength and affinity to the oil,  resulting in a strong reduction of friction and wear. NanoGraphite is working as a natural and extremely efficient dry lubricant reducing the friction further (see also www.addo-oil.com).
Your engine becomes more efficient, it uses less fuel and lives longer.
