do new sealed gas cans keep regular pump gas mix longer

[echomeister]

Supposedly the new cans are sealed.
Ex: No spill gas cans.

No air in or out. So pump gas with a stabilizer should last for a while.

If you keep it in a temp stable environment. Like in a barn on the shaded side at ground level.

No plastic can is truly vapor tight. And with stabilizer, in a proper can, fuel can last years.

I was thinking more like nato jerry cans.

These swell and contract with temperature swings. Gasoline has much higher vapor pressure than water and the change with temperature is significant.

...or blocks all sunlight, which also degrades gasohol, or blocks all oxygen (see: plastic paint pails) which also breaks down gasohol.

Plastic gas cans are garbitch. I wouldn't pay a nickel for one, let alone 15 or 30 bucks.

That would take a lot of them to store any amount of fuel lol.

Yep, I have one left for kerosene. We use kerosene heaters every now and then, and just run out and get 5 gallons when we need, and it gets used right away. It will eventuality get replaced with another nato jerry can. All my diesel and gas cans have been replaced now.

The 1-gal cans are handy to carry in the woods. I do have old metal fuel cans that totally seal the fuel. Those go to the airport to restock or 91 non-corn stuff if I'm running the saws a lot/milling.

I keep my no spill cans in the barn and they still swell and contract with temperature changes.

But they are better than vented cans. Fewer volatile compounds escape. Besides being pollution, those are what vaporizes in a cold engine to start it. You want them. Vented cans "breathe" with temperature changes. When they warm up they exhale. When they cool they inhale. Every breath in brings in more water vapor. Every breath out loses more of the volatiles.

I have not used vented cans in forever, so I can't say from experience how much longer the fuel will stay usable in unvented vs vented cans. Before I used the no spill cans I used motorsports plastic jugs except for race gas which came in sealed metal cans. The no spill cans perform at least ass well as my old motorsports jugs as far as gas stability goes.

While I can understand the frustration with how slow the no spill cans pour, punching a vent hole in them makes them the worst of all worlds. Now they leak fumes, will leak gas if tipped over, lose the volatiles you want, and gain water vapor. All bad.

I use the same type of can. At work we use Stihl moto4 for winterizing customer equipment. I saved several of the empty cans to use for fuel storage.

Do you have a good source for ~1 gal NATO cans?

 

[Chevboy0167]

How about 2.6 gallon.....? They don't give em away that's for sure!

Thanks for the links.

That's actually a good price, but they're knockoff Chinese fuel cans. Just seeing the center seam is sticking out, instead of recessed into the tank, would be an automatic fail for me.

I'd rather go with something more along these lines. Old and dusty on the outside, but legit genuine NATO cans.

I believe you will find that if you fuel up from a modern station their underground tanks are indeed plastic. Of course being underground changes a bit. It does remove the sunlight issue but does not removed the perceived oxygen issue.

Fuel stations rotate their fuel constantly; a truck stop may get a fuel delivery every day. You could store gasoline in an open top container, and it'd be fine if the gasoline was replaced daily too.
