Does Fuel Stabilizer Ever Go Bad?

[Alex65]

Hi: Quick question. I have two bottles of K&M Fuel Stabilizer. One is about 3-4 years old, the other I bought this winter. Does fuel stabilizer itself ever go bad? <br /><br />The reason is, I just bought a Honda 2 HP Four Stroke OB & a Tothatsu 9.8 2-Stroke. I'll maybe use a gallon of gas for the Honda & go thru 2 each 3 gallon external tanks with the Tohatsu for the season.<br /><br />Any insight would be appreciated!<br /><br />Alex

It shouldn't go bad if the covers were on tight.<br />Otherwise some of the alcohol and other ingredients may have evaporated out.<br /><br />I sure hope it doesn't go bad. I buy the big gallon jug of the stuff, and it takes a while to use it up.

If I remember right the bottle of Sta-ble I have says it is good for 1 year after opening?

I'm going to call the manufacturer tomorrow & check. Just to be on the safe side. I'll post later, when I find out. If anyone else has this same question on their mind.<br /><br />Alex

That is a good question. I would be curious to see what they say...

Well, I called the manufacturer & they said it's usually good for 24-30 months. So, I'm going to dump the older stuff & date (on the bottle) when I opened the new one. Just an FYI for those people who may hang on to their fuel stabilizer.<br /><br />Regards,<br /><br />Alex Moore

One of the main ingredients is isopropyl alcohol. If it's been opened, it will evaporate rather quickly, leaving a higher concentration of the other ingredients.
