Strain it through a chammy skin to separate the water, mix in some
"heat" and put it in the gas tank of your car a half gallon at a time
with a full tank of gas. If it has 2 cycle oil in it, that won't hurt
True, and in any sizable quantity I would agree wholeheartedly. For a
little waste leftover from washing a few parts, for example, I decant
the solids and save it what's not too bad for next time then use the
small amounts for things like ant hills, etc. If it's in an area
removed from other things, I'll usually light it off after a little
while and that will eliminate most of the residual...
The responsible way is to take it to the dump on a day when they accept
household hazardus materials. My city has one per month free to residents
with some limitations but a gallon of gas would be no problem.
The easy way is to leave it in an open container and let it evaporate which
someone would point out causes air pollution. It's a little too much to
burn and definately not legal to dump it anywhere and downright dangerous to
dump it in a drain (sanitary or rainwater)
There's nothing wrong with the gasoline, as the water will sink to the bottom,
not mix. This happens all the time (like everytime it rains) with some
airplanes left outside. It seems to happen more with flush mounted fuel caps.
You don't toss away fifty gallons of very expensive aviation gas, you just keep
sampling the bottom of the tank until there is no water (and other
contaminants) in the sample. Avgas is typically sampled from each tank and the
lowest place in the fuel system after filling the tanks and before each flight
for just this reason. Water is no problem once it's been drained out, and
water always falls to the bottom of a tank of gasoline.
All you have to do is decant off the gasoline. The chamois cloth technique is
a good idea.
Using gasoline for weed control or pouring it on the ground is a very bad
idea. Today's gasoline contains many substances (e.g. MTBE, benzene) that
don't break down anytime soon and will continue to sink down into the ground
and contaminate the water table. A very small quantity of gasoline can
contaminate a lot of ground water for many, many years. Cleanup is very
expensive but unfortunately not very effective.
Yes there is. You buy a genuine chamois cloth and run the gasoline
through it. The water will remain in the chamois and the gasoline will
then be water free. An easier way is to dump it in a larger gas can and
add a quart of alcohol then pour it into a nearly full fuel tank of a
vehicle that will run on regular gasoline.
Contact your municipality for local HazMat regs. They will inform you as to
the proper way to dispose of your gasoline. Most likely they're going to
direct you to a nearby recyling center.
