One thing everyone missed is the fact that, with time all kinds of garbage
in your tank builds up and sinks to the bottom. Running on an empty tank
causes the fuel pump to suck the crap in and clog your filters, lines and
injectors. If you have a dirty injector, your fuel consumption will be high
too.
The condensation thing I believe, this is why when people with boats store
them for winter, they fill up their tanks, to avoid condensation.
