Why VitaFlush contains revitalizant.
If you have used a regular oil without revitalizant before, you have noticed that every time you change used oil you move away small metal parts which have been abraded from different rubbing surfaces (ring ?cylinder, shaft journal ?bush, etc.).
Formerly it was an irreplaceable loss for the engine itself and forthcoming repair could be figured out by the number of oil changes. Thus 4 liters of used oil contain about 3 grams of metal. The calculation is very simple. The reason for major repair is the loss of about 60 grams of metal in the engine with working volume 1800 cc! But now due to the invention of revitalization effect it is possible to return up to 70% of the lost metal!
