If some of the vehicles in your fleet were recently refuelled more than once within a day using any fuel card, an exception report can be generated to notify you. The report outlines how many vehicles were refuelled more than once in a day, how much tank capacity was utilised when refuelling, and how much fuel was utilised before refilling.
Since each fuel refill can incur a transaction fee, filling your vehicle to full capacity and only refuelling when necessary, is an opportunity for you to save.
