60 litres of Petrol

When I fill up my car’s petrol (gasoline) tank, all I see is a black hose going into my car and some numbers on the meter. I don’t see the large volume of petrol quickly streaming into my car’s vast fuel tank. I am insulated from the fact I have just bought 60 litres. When I picture in my mind how much 60 litres actually is, three large 20 litre buckets, or 6 x 10 litre buckets, it impresses on me how wasteful it is to use a 1300kg (2,800 pound) car to transport little old 100kg (220 pound) me.
