BIZOL Friction Modifier+ o94 is a high-tech engine oil additive based on nano-technology, which is made in Germany. It has been specially developed to reduce friction on mechanical parts, optimise engine operation and provide long-term protection. Under magnification, the metal surfaces inside the engine are rough, even surfaces that look polished. Friction occurs when rough metal surfaces rub against each other and friction equates to wear plus increased fuel consumption. BIZOL Friction Modifier+ o94 chemically "hardens" the metal surface, forming a smooth protective layer on the heavily stressed friction surfaces by building up chemically active nano-structures ("bottom-up"). The internal engine coating which is formed reduces friction and wear without clogging oil filters and oilways. TÜV certification confirms reliability of BIZOL Friction Modifier+ o94.
