|Always keep your tank full
of teenagers love to pass down this sage nugget, perhaps recalling
all the times they ran on fumes during their wild youth. It
turns out to be pretty sound advice, too.
"You always want to keep
fuel in it in wintertime because you don't want water to get
into your tank, because tanks sweat," says Martin. "When you
pull in and out of your home garage, you can get moisture
in it just because gas is cold and when you bring it into
a warm garage, moisture can build up and sweat. You'll get
some definite running issues with that."
Duchene notes there are
plenty of practical reasons to run full, as well.
"For instance, let's
say you have to borrow a car. You start it up and the gas
gauge stays on 'empty.' You might think maybe the gauge is
broken," he says. "Face it: A car without gas is
no car. If you have an emergency in the middle of the night,
you couldn't do anything about it."
What's more, if you get
stranded in a blizzard without fuel to run the heater, your
miserliness just might cost you your life.
