Airships Well, let's do the calculation: let assume gasoline that is all octane: that's C8H18. 18 hydrogens gives 9 molecules of water for each of gasoline. Actually, gasoline is less than that, it tends to be a lot of heptane and some nonane, etc... So give it 8.5 (8 would be pure heptane). However, car engines are about 1/4 efficient, so make it a little above 2 waters/gasoline. Then remember, water is denser than gasoline. The specific gravity of gasoline is about .8. And 2*.8 = 1.6 but this is all estimates. So, yeah, about 1 1/2 is a good ballpark guess. I'll give it to you. It might be more in new fuel efficient models.
