What to do with old stale gas?

[kerry]

quote George Emmanuel:

I use it in my riding lawnmower and mix it with newer gas and it does fine.

X2. Most lawn and garden items with Briggs, Techumseh, or Kohler 4 stroke engines will burn it. I add a dollop of Seafoam with it. No issues ever.

If you have too many, AND not enough, you're a collector.

My recycler takes all the old gas you bring him, and burns it in his waste oil heater. He told me this summer, that there is an over abundance of drain oil out there, due to low gasoline prices. So don’t keep it around to long, as you may have to pay to get rid of it.

I usually use it up in my mower too. I’ll keep it and run it in my outboards if it’s not over a year old though. I use ethanol free fuel in my outboards so no phase separation. The low compression 2 strokes don’t seem to complain too much about old gas unless it’s really stale. If I use a gallon or so in the 10 gallon tank of my Scag zero turn, I have no issues. I use about 3 gallons of gas every time I mow.

quote 20mercman:

My 1986 3/4 ton 454 Suburban is a real dinosaur in that it has no catalytic converter or onboard ECM. This is also a rather thirsty machine. I run old gas through it in diluted form. Of course, not talking about phase separation ethanol gas failure, but a bit old, and it runs just fine. I do make sure I screen it through a coffee filter before use just to make sure I don’t dump a bunch of junk into my tank. It holds 40 gallons, so adding two gallons to a tank is not going to hurt a thing.

I think Steve makes a good point in that if you are going to try and run it through another motor, make sure it’s not ethanol gas that has a lot of water in it????? At least for me, that would be a concern.

.The air contains a certain amount of water
depending on where you live. It can be seen
on the lawn or you cars in the morning before
it goes back into the air. On a rainy day the
air is saturated with water that is pulled into
an engine as it runs and its not an issue for
the converter. What would be an issue is the
oil. Putting a gallon or 2 of gas that has 6 or 8
ounces of oil per gallon into a cars gas tank
that is half or less full could possibly overwhelm
a converter. If it was to cause a partial blockage
that would increase the load on what that remains
open. This could lead to a failure at a later time.
The oil wouldn’t the best thing for the Oxygen Sensor
either. Here is a link to what will cause a converter to
plug up.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

That’s my concern over using it in a modern car. Modern automotive power plants are complex and expensive to repair. Just check the price of an injector! I have no problem using it in an old tractor or whatever. Phase separation seems less likely to me with 10% ethanol content, as the ethanol is miscible with both water and hydrocarbons, but maybe I’m missing something here.

If you have old stale gas you are obviously not running your motors enough. . . 🙄

[shoestringmariner]

I use mine as bonfire starter or mix small amounts of it in other equipment. Mostly use it by diluting it in running it in my lawnboy at the end of the season

When I was 10 years old I disposed of old lawn mower gas by pouring it into coal furnace….
Resulting explosion convinced me I had made an unwise move. Running stale gasoline
thru an old farm tractor seems both wiser and more useful.
I am no fan of poison ivy so use of gasoline as a herbicide is acceptable so long as
you do not start a fire….local volunteer fire department once had to put out a brush
fire involving poison ivy. After effects well remembered years later.
