Fuel Stabalizer

[drseti]

Fair question, Brian. I don't use them in my aircraft, for two reasons:

(1) I operate with 100LL, which has a longer shelf life than mogas.
(2) Even if I had mogas available, my flight school aircraft flies so frequently that fuel doesn't stay long in the tanks.

As for recommendations, I tell my maintenance customers who use mogas to go with the airframe manufacturer's recommendations. Some specifically prohibit additives, because of fuel system incompatibility (just as some prohibit ethanol). Others recommend specific additives.
