Recognizing that this is somewhat complicated, but I fairly frequently travel to another country via car and fill up, so pay in a different currency. I recognize that this complicates various comparisons, but maybe set a default currency, then at time of fill-up, allow for the selection of another currency, then convert that currency at the day of transaction's exchange rate to the base currency.
