What type of products can I purchase on a fuel card?

The Fuelcard People answer: You can use a fuel card to pay for a range of oil-based products, including diesel, petrol, oils and lubes, depending on the purchase category of your card. A different set of products can be selected for each card. Most cards allow the purchase of fuels and lubricants and some also allow you to purchase HGV truck wash, selected tolls and HGV parking.
