Present invention optimizes utilization of different fuels in various single and multi-fueled engines. The fuel system and optimization controller links fuel properties (physical, reactionary, combustion etc.) to on-board computer systems during the refueling process. This link enables fuel and additive producers an opportunity to optimize combustion parameters of their proprietary fuel blends to increase performance, fuel efficiencies and reduce emissions.
