Shelf Life of Gas Stabilizer.

[George7941]

A neighbour left this bottle behind when he moved out. No date code on the bottle but it looks a bit old, best guess around five years. Ingredients are listed as 1,2,4-trimethylbenzene and mineral spirits. Does anyone know if there will be any harm in using this in my motorcycle tank during storage over the winter?

Stabil recommends using their stabilizer within 2 years of opening the bottle

+1 with the 2 years. Just put it in your daily driver and use it that way. It won't cause any harm.

I've been told the stuff is good indefinitely...that's not that old of a bottle.

I need stabilizer for my stabilizer?

Two years is or was on the StaBil label. Toss it.

What do you think its going to turn into? Still, I suppose you don't want to take any chances.

Most stabilizers also contain diphenylamine, an antioxidant. I have had stabilizers on the shelf for 5 years and they never degraded. If concerned, dump it in your gas tank.

Or, do what I did with my last jug of Motomaster stabilizer, "dump" it all over my shelf in the garage. I didn't tighten the one cap right, and pressure caused a whack of the stuff to migrate up the measuring side and make one heck of a mess.

won't have to worry about termites on that shelf anyway!

 

[Garak]

No, they shouldn't be a problem. At least it sort of "dried up" and wasn't the long term sticky and/or greasy mess I was expecting. The bottle wound up being more sticky than the shelf, of all things.

I was using the blue marine stabilizer for some various things, mainly for the generator and a motorcycle not used much. Notice it turned dark, almost black. It was kept in the garage for a couple years or so. Folks here @ BITOG says its time to get rid of it (shelf life) and so I dumped it in the DD and got a fresh bottle.
