One problematic additive is ethanol, often found as 10% of gas pump fuel volume. Ethanol absorbs water vapor from the air, then settles to the bottom of the gas tank or carb bowl, and corrosion or deposits may ensue. Drain tank & run engine until carb is dry, or use canned fuel, or add stabilizer like SeaFoam and fill tank to the very top. Ethanol-free fuel is available, but may be hard to find, see: https://www.pure-gas.org/ https://www.pure-gas.org/
- genewitch 2y agosome states sell ethanol-free gas (ours in LA are blue pump heads, diesel green, e85 is yellow, and regular gas is either red or black depending on the service station. One of my neighbors has a shadetree business repairing small motors and he taught me to always use ethanol free, and instead of draining it (since it's got ethanol in it) to use the fuel shutoff valve and let it run the bowl dry itself. I don't have too much small gasoline stuff left that i care about (a weedeater and a couple of honda generators i never use), my tractor is diesel, and my whole-house generator is propane (from a small tank, haven't needed to upgrade since i got the generator shortly after Hurricane Laura.)
