For anyone that's interested, I am a big fan of the "Fitch Fuel Catalyst" products. Rather than a liquid you add to your gas tank, these things are a type of pellet that you throw into the tank, or a cannister that you add in series into the gas line. Being a catalyst, it's non- sacrificial, so it's a one time deal. - - put it in and forget it - no further purchases necessary. The kits come in different sizes, for different applications. I have one set of pellets that I threw into my 5-gallon gas can, and the cannister type that I installed on our Jeep Liberty.
My gas can can sit for months on end, and the gas remains fresh - you can even tell by the smell. Since buying the thing, all my small gas powered tools run way better, and more reliably. I don't pretend to understand the process, but the claim is that the catalyst somehow furthers the refining process of the gas indefinately. - - All I know is that for me it works. It's not cheap, but for me it's worth the time I save in jacking around cleaning and adjusting carburetors, fuel tanks etc..
