I believe gas line antifreeze is mostly methanol [with anti-corrosive additives], different critter than ethanol .... to the question, there's no problems using E10 or 15 in stovebolts, not sure you'd want to be using AVgas,
even 100LL still has lead additive, which doesn't sound "safe" to me, and any dyed fuel is illegal on the road here [av, marine, or farm gas]
