I my youth, some of us used castor oil in our two stroke mixes to give pleasanter smelling and perhaps less smoky exhausts. The Aerial needed a lot of oil and produced quite a plume. Others used simple engine oil. All oils will dissolve in petrol.I have no concerns about using petrol as supplied at the pump.
If I were to have any, it would be with regard to how the oil mixes with different petrol formulations, but I would assume that the oil manufacturers would be on top of it.
Two stroke specific additive oil has various additives to improve stability/performance etc, but I cant see how the additional of moderate ethanol would impact them
