Re: OT, somewhat

Well, if that will work, how about filling the gasoline tanks of various lawn engines with argon so as to keep the oxygen from deteriorating the gasoline?

I know that there are 'stabilizers' just for this purpose but the want money for them.

I suppose it would work, never tried it myself, but you'd need to seal the filler cap... often they are vented.

I thought 4/5ths was still there ?

If you hold your breath for a bit before you exhale then it will be lower than that. Anyway, that's why I said 'relatively oxygen depleted'. It's not as good as inert gas, but it's free.

Yes, the gum/varnishes are present in the carburetor, too.

I dont' recall if the mfg. of the stabilizers require you to run the engine after putting in their product. I would assume so. If so, then, you are right, just sealing the meniscus of the gasoline wouldn't do much good.

My father had spray cans used for preserving paint, varnish, or what ever. You sprayed into the can just as you put the lid down. It worked very good, but it is no longer sold because of ozone issues. I have many times thought of using argon, I know the last can of marine varnish I bought was expensive. You try to use the last drop. The marine varnish is amazing stuff.

Well, you could do a 180º and get methane. That's not inert, just loud.

I was joking about the methane and the end it comes out of, too.

There's some commercial stuff called "Bloxygen" IIRC, but for years, I have used a quick squirt of whatever it is thats in lighter refill aerosols, then store the can upside down. It has worked well for me, well for about 5+ years anyway.

As far as I can tell from the label, it's a mix of propane and butane.
