I thought that the Transit van had an 80 litre fuel tank, No heres my little problem........
I had 67 miles left in the tank..
My van is doing 27.87 miles to the gallon (working out between fill ups), so to my maths, if we round it off to a round figure (28) I should of had left just over 2 gallons ( 9 litres + a little more for the 11 miles) till empty, and yet I have just filled up and put in 79.12 litres fuel (£114.65 ), now work that one out ?????
