Check the ingredients. I recall "dry gas" being basically ethanol.
Ethanol can absorb a certain amount of water, but after a point will seperate from the gas, just in case you're running E10.
Gas line antifreeze is hard on carbs with diaphams. and rubber gas lines. I would use isopropyl alcohol instead. You can get it in any drug store. Get the highest percent you can find. We use it in the canadian north a lot. To prevent ice crystals in the gas. You can cut it in half with water and it will still burn on a spoon. Much like the stuff from a good still and a potato mash.
