Pour the contents of one bottle in a preferably clean or just replaced fuel filter and let the engine run directly on the product.
One 500 ml bottle is sufficient for most curative and preventive use. In extreme cases a double doses can be used. To maintain a clean fuel system and an optimal performing engine regular use of TecLub diesel treatments is recommended.
