We have an ASDA 24/7 here, so that is where I normally fill the tank.
I actually don't use a lot of fuel as I prefer to walk, and if we are going somewhere, hubby usually likes to drive his car, so we end up taking that.
First week of July we were on holiday, and a 300 mile drive lay ahead. Before we went I TOLD him we were taking my car.
I think the tank holds 60 litres, and we got there on half a tank. Although by the time we got there, I couldn't have cared less as I was so tired.
Usually one tank will do me for around two months, so it shows how much I drive. Come to think of, I think I noticed a few grey hairs on hubby when we got back, and I have no idea what the reason for that might be.
