Badmoonraising Posted November 4, 2016 Report Share Posted November 4, 2016 Is it advisable to you gas stabilizer in Avgas? Quote Link to comment Share on other sites More sharing options...
carusoam Posted November 4, 2016 Report Share Posted November 4, 2016 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 Best regards, -a- Quote Link to comment Share on other sites More sharing options...
KSMooniac Posted November 4, 2016 Report Share Posted November 4, 2016 No need...avgas is extremely stable due to the spec requirements. Sent from my VS985 4G using Tapatalk Quote Link to comment Share on other sites More sharing options...
Badmoonraising Posted November 4, 2016 Author Report Share Posted November 4, 2016 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! Quote Link to comment Share on other sites More sharing options...
carqwik Posted November 4, 2016 Report Share Posted November 4, 2016 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!) Quote Link to comment Share on other sites More sharing options...
