ChatGPTCalculates an ethanol blend for a fresh tank, existing fuel, correction, or ratio without authentication or account-data access. Percentages are 0–100 and all volumes use the selected unit. Source ethanol contents are measured values. Fresh mode requires finalVolume; existing mode requires finalVolume, currentVolume, and currentEthanol; correction mode requires tankCapacity, currentVolume, and currentEthanol; ratio mode requires no volumes.

calculate_race_fuel_and_weight
ChatGPTPlan a race fuel load, reserve, start weight, and projected minimum-weight margin. Calculates from measured inputs without authentication and does not read or save account data.
