POWOIL fuel additive DIESEL is an additive recommended as euro-diesel supplement, designed to improve fuel lubricating characteristics and to protect sensitive parts of the injection system against wear. POWOIL Diesel fuel additive is intended for oldervehicle engines, which have been previously using D2-type diesel fuel. Supplementing this additive to the fuel helps a protective layer be formed on the metal surfaces of the injection system, thus reducing friction and increasing fuel lubricity. This kind of product is compatible with other fuel additives. It protects the high-pressure fuel pump, as well as direct, indirect and common rail injection system against wear. Application: according to the ratio listed on the packaging label.
