Any fuel Borrowers buy for your car will be charged to you on your monthly invoice. You may be charged more for fuel than the distance income you receive, because Borrowers may purchase more fuel than they use. The extra fuel is now in the tank for you to use, or for another Borrower to use and pay for.
You may find that the cost of fuel paid for with the fuel card exceeds the distance income you receive - particularly if the tank is filled near the end of the month.
A Borrower picked up Jan's car with a quarter of a tank. They filled up, then used half a tank of fuel during their trip. At the end of the trip, Jan is left with half a tank.
Jan is charged for all the fuel purchased by the borrower (three-quarters of a tank). She gets paid for the half-tank of fuel that the borrower used, through the distance income. But she also has the other half a tank of fuel - she may use it herself, or the next Borrower may use it and pay her for it.
