As I said in earlier posts, I bet that is alkylate gasoline. In Sweden that is the only fuel used for small engines in the forestry industry. Why? Because of shelf life, non toxic fumes, constant specification. There are almost only upsides, the cost is lower than the cost for extra maintenance on the equipment, you don't get headaches and you don't have to adjust your saw with new gas batches.
But remember, it is not just "E0", it is a synthetic gasoline.
Common brands here are Aspen and Stihl, but you can find it at the pumps too, especially in marine pumps and farm stations.
