The high-octane component is an effective mixture of isopropanol with the addition of diisopropyl ether (DIPE) and a composition of functional additives, providing protection of the fuel system from corrosion and improving anti-wear properties. In the maximum concentration (10%), the APDC 3014 component provides a 2,8-3,5 point increase in the octane number of the high-octane base (RON = 89-92), which corresponds to the blending RON up to 125.
