Please anyone in the UK running their aircraft on a LAA permit do NOT add

insurance company may also rebel, . It may work but is not approved for use
in the UK

Subject: Europa-List: Re: Fuel stabilising
I add 2 grams of BHT (food grade butylated hydroxytoluene) anti-oxidant per
5 gallons ethanol-free mogas anytime I don't immediately use the fuel.
BHT is readily available on eBay (much cheaper than Sta-bil and possibly the
same stuff, but without all the petroleum distillates that I don't want).
BHT dissolves instantly in mogas.
This is about 2 grams per 2700 gm of fuel, or 0.07%, or about 0.7 ppt. Not
very much! Possibly not even enough anti-oxidant for all applications. My
goal is to mitigate the formation of gums or gummy deposits in the carbs.
Many years ago I used small amounts of BHT for the same purpose in a
hydrocarbon-based rocket fuel for the US Air Force.
