For the wife's car I bought the product. On the recommendation of an engineer, car specialists and Restaurateurs who told me what makes this means and what it is good. It just makes everything like new, just when the new engines with the filigree Common Rail pumps, nozzles and so on. Best before winter and after winter, so even apply in two. You should definitely wear vinyl gloves or similar protective gloves and use the funds in the open air. It stinks of chemicals and death should best not be inhaled. Since my tank is small, I consume only 1/3 of the bottle with an application. That's stupid because I have to appreciate so much was already purely tilted out of the bottle. Even the filling is super inconvenient because spills guaranteed and the remaining drops from the filler neck must be absolutely wiped out. For transport to the filling station necessarily a sealable plastic bag, gloves and a paper towel to take! The car uses two tanks for more, but there is a wellness treatment for the cars. Dear risking the stuff here than an expensive repair.
