I always find it a bit sobering to think that the 50 tonnes or so that a 330 will drink on a pond-crossing will keep an average family car going for about 25 years.
(Give or take a bit - calculation done very very roughly on the back of a fag packet - I expect that there are many far cleverer than me who could come up with something more accurate with regard to fuel burn and CO output etc - I just like the family car simile!)
