fuel stabilizer

Is it advisable to you gas stabilizer in Avgas?

100LL is a very well stabilized fuel already.  It doesn't have the volatility that automotive fuels have.  No light weight stuff that quickly evaporates with time..

How long do you intend to keep the fuel you have?  Some people use 100LL in their airport vehicles that sit around and hardly run like a tug...

The opposite challenge that 100 LL has, it is a bear to start when the temps get below 30°F

No need...avgas is extremely stable due to the spec requirements.

Thanks, I didn't know that. 

I re-read my post. It was so poorly worded I had to give you top marks for knowing what I was asking!

I use the discard avgas from my fuel tank sump for my gas tug...just add the avgas in to the unleaded auto gas in the tug's tank.  The auto gas is probably six to nine months old at a time...yet the tug always starts on the first cord pull...and the carb isn't gummied!  So that's a pretty good test of how stable just a bit of avgas is...(my opinion of course...zero scientific knowledge!)
