In at least some embodiments, the fuel authorization controller at the vehicle automatically uses the fuel tank sensor data and known tank size to include in a fuel authorization request sent to a fuel vendor data defining how much fuel is required to fill the vehicle fuel tanks. In at least some embodiments, the fuel vendor consults data from a source other than the vehicle (such as records maintained by the fuel authorization program) to determine how large the vehicles fuel tanks are, and to calculate how much fuel is required. ## Claims ### Claim 1 A method for administering a fuel authorization program, the method comprising the steps of: (a) automatically sending a fuel authorization request from a vehicle fuel authorization processor at an enrolled vehicle to a vendor fuel authorization processor at a fuel vendor, by having the vehicle fuel authorization processor automatically implement the steps of: (i) obtaining a fuel tank reading from a fuel tank sensor at the vehicle to provide an indication of how much fuel is required to fill a vehicle fuel tank; (ii) retrieving fuel authorization credentials from a memory at the vehicle; (iii) communicating the indication of how much fuel is required and vehicle fuel authorization credentials from the vehicle to the fuel vendor;

(d) automatically using the vendor fuel authorization processor to determine if fuel delivery was terminated early at the fuel pump to prevent spillage; and if so, automatically using the vendor fuel authorization processor to send a communication from the fuel vendor to the vehicle indicating that less fuel was delivered than was requested; (e) in response to receiving the communication from the fuel vendor that less fuel was delivered than was requested, automatically using the vehicle fuel authorization processor to apply a calibration factor at the vehicle, so that subsequent fuel tank readings will be more accurate. ### Claim 2 (depends on 1) The method of claim 1, wherein the step of automatically using the vendor fuel authorization processor to send the communication indicating that less fuel was delivered than was requested comprises the step of automatically communicating to the vehicle how much fuel was actually delivered. ### Claim 3 (depends on 2) The method of claim 2, wherein the step of automatically using the vehicle fuel authorization processor to apply the calibration factor at the vehicle comprises the step of automatically using the vehicle fuel authorization processor to apply a calibration factor that tends to overcompensate based on how much fuel was actually delivered. ### Claim 4 (depends on 2) The method of claim 2, wherein the step of automatically using the vehicle fuel authorization processor to apply the calibration factor at the vehicle comprises the step of automatically using the vehicle fuel authorization processor to apply a calibration factor that tends to undercompensate based on how much fuel was actually delivered. ### Claim 5 (depends on 1) A non-transitory memory medium having machine instructions stored thereon for facilitating a fuel transaction with a vehicle, the machine instructions, when implemented by a processor, carrying out the functions of steps (b), (c), and (d) of claim 1. ### Claim 6 (depends on 2, 8) The non-transitory memory medium of claim 8, further having machine instructions stored thereon for implementing the step of claim 2. ### Claim 7 A method for administering a fuel authorization program, the method comprising the steps of: (a) automatically sending a fuel authorization request from a vehicle fuel authorization processor at an enrolled vehicle to a vendor fuel authorization processor at a fuel vendor, by having the vehicle fuel authorization processor automatically implement the steps of: (i) obtaining an initial fuel tank reading from a fuel tank sensor at the vehicle to provide an indication of how much fuel is required to fill a vehicle fuel tank; (ii) retrieving fuel authorization credentials from a memory at the vehicle; (iii) communicating the indication of how much fuel is required and vehicle fuel authorization credentials from the vehicle to the fuel vendor; (b) automatically using the vendor fuel authorization processor to analyze the vehicle fuel authorization credentials to determine if the vehicle is authorized to receive fuel; (c) after determining the vehicle is enrolled in the fuel authorization program and is authorized to receive fuel, automatically using the vendor fuel authorization processor to enable fuel delivery at the fuel pump the vehicle is proximate to in a quantity sufficient to fill the fuel tank based on the indication of how much fuel is required communicated from the vehicle to the fuel vendor; (d) after fuel delivery is complete, automatically using the vendor fuel authorization processor to communicate to the vehicle fuel authorization processor how much fuel was dispensed; (e) after fuel delivery is complete, automatically using the vehicle fuel authorization processor to obtain a subsequent fuel tank reading to determine if a change between the initial fuel tank reading and the subsequent fuel tank reading corresponds to what is expected based on the how much fuel was dispensed; (f) if the subsequent fuel tank reading is not as expected, automatically using the vehicle fuel authorization processor to apply a calibration factor at the vehicle, so that subsequent fuel tank readings will be more accurate. ### Claim 8 (depends on 7) The method of claim 7, wherein the step of automatically using the vehicle fuel authorization processor to apply the calibration factor at the vehicle comprises the step of automatically using the vehicle fuel authorization processor to apply a calibration factor that tends to overcompensate based on how much fuel was actually delivered. ### Claim 9 (depends on 7) The method of claim 7, wherein the step of automatically using the vehicle fuel authorization processor to apply the calibration factor at the vehicle comprises the step of automatically using the vehicle fuel authorization processor to apply a calibration factor that tends to undercompensate based on how much fuel was actually delivered. ### Claim 10 (depends on 7) The method of claim 7, further comprising the step of automatically using the vehicle fuel authorization processor to determine that fuel delivery is complete by at least one of the following techniques: (a) automatically determining that the vehicle has been powered on; (b) automatically determining that the vehicle has been placed into gear; (c) automatically determining that the vehicle has exceeded a predefined RPM; (d) automatically determining that a data link with the fuel vendor has been terminated;
