That fuel doesn't have the alcohol in it that pump gas does, so you avoid those problems.
Once the can is opened though, it's going to start to "age". How fast????
Personally, I wouldn't save it for the following year.

I can't knock it. I remember when they started selling bottled water and did people laugh. Hmm the laughs on them.
For someone who doesn't want to be bothered with mixing it is good for the homeowner who uses their gas trimmer lightly.
Also it comes in different ratios.

The stuff I found on Amazon goes for over $20/Gal and claims, "Premixed and ready to use formula with synthetic oil, a fuel stabilizer and ethanol-free gasoline."

I will pass.
I saw it at our local HD. 6 pack 34.99. $5.83 a quart.

Good thing that they claim is a 5 year shelf life if unopened and a 2 year life once opened.

I'm going to try it. This is also an issue at home, where I go through maybe two quarts a year, and have to mix the gas and oil in very small quantities. Wife not happy when I use the kitchen measuring spoons for 2-cycle oil!

I don;t know if they have ethanol free gas where you live, but you can get it for about $1-1.50 more per gal. where I live.
IF you have that available, you might consider mixing up a gal. of that and dumping what's left over at the end of the summer into your car.
You can use your 1 qt. container for the cabin and bring back what you don't use.

Here, "PURE" gas, as ethanol-free fuel is called, sells for about 20 cents more per gallon. Not a significant price differential considering the small amounts used in lawn equipment.

I've been using this fuel for a few months now in my trimmers and blowers. I really like it. I'm using both the 40:1 and 50:1 and I have no complaints. It's also supposed to have a very long shelf life.
