Processes for blending at least one finished gasoline from a refined petroleum product comprising at least one neat gasoline with ethanol and optionally butane utilizing a blend model that calculates a volumetric blend ratio comprising at least one neat gasoline, ethanol and optionally, butane. The blend model utilizes estimated values for the octane number and the volatility of the ethanol and butane when calculating the volumetric blend ratio.

A fuel dispenser comprises a fuel nozzle configured to be connected to a vehicle fuel system and fuel piping configured to transfer fuel from at least one fuel storage tank associated with the fuel dispenser through the fuel nozzle into the vehicle fuel system. A flow control valve is located along the fuel piping. A fuel dispenser controller comprises processing circuitry configured to receive vehicle fuel system data from a vehicle, determine a desired flow rate based on the vehicle fuel system data, and control the flow control valve to prevent a fuel flow rate from exceeding the desired flow rate.

Fuel dispensers, systems, and methods are provided for allowing a user to dynamically create a customized fuel blend, also referred to as a fuel mixture. In an exemplary embodiment, a fuel dispenser is provided having an interactive display, such as a touchscreen display, and a data processor that can perform operations that enable any one or more of replacing PTS buttons, integrating additive pumps to combine fuel mixtures and additives, mixing fuels and additives, calculating fuel mixture prices, and allowing a user to customize fuel mixtures. The application of the interactive display and the control module, as well as other components, can facilitate allowing a user to create customized fuel mixtures, while minimizing changes to standard communication protocol associated with components such as, e.g., a point-of-sale (POS), a forecourt controller, and a fuel controller that can control dispensing of fuel.
