It’s inevitable

Great post. Are there any chemicals in fuel stabilizer that are on the list of things that GM say not to put in the tank? I can’t pronounce most of them let alone know what they are. And as for leaving a battery on a concrete floor that no longer applies with modern battery technology. Mainly due to the battery casing being totally impervious to moisture. If the floor is cool it’s actually a benefit. From Perplexity AI …..
Yes, you can store a car battery on a concrete floor. Modern batteries are encased in durable plastic, which prevents moisture absorption and degradation that older batteries faced when placed on concrete. The myth that concrete causes batteries to discharge faster originated from older battery designs made of porous materials. In fact, storing batteries on concrete can help maintain a cooler temperature, reducing self-discharge rates. Just ensure the battery is clean to avoid any potential surface discharge from dirt or grime.

I had a quick look and GM doesn't seem to make their own gasoline stabilizer - they make a fuel conditioner that's meant for cleaning fuel injectors etc. but not the antioxidants and corrosion inhibitors that a fuel stabilizer has. "Corvette Forum" has some discussion on it, most people use Sta-bil or similar products made by other companies. They also mention Sta-bil 360 which is meant to reduce issues with ethanol fuels, but the info I found on that stuff doesn't say anything about using it as a storage additive. Sta-bil has been around for decades, used by a zillion people, and I didn't find anything negative about it, so I think we're on pretty safe ground with it - but you do want to use the correct amount, and follow the instructions to ensure it gets mixed properly with the gas in your tank.
Best practice is to use a fresh tank of Premium gas, which has higher additive treat rates, and, at least where I am, typically will have less or no ethanol in it, and keep the tank full to minimize tank vapor space "breathing". Add Sta-bil during your last tank fill, to let it circulate through the fuel system before you put the car to bed.
By the way: I've never had any luck with the goofy pre-measuring gizmo on the bottle - so try it out first, or use a funnel (in addition to the one that came with your car to add gas with a jerry can) or you may end up with half of it on the side of your car when you try to pour it into the tank :mad: just sayin'

Sta-bil does seem to be the product of choice. And yes the built in measure is a pain in the tush . I put a bottle in mine the day before yesterday and filled the tank . I always hold a rag or paper towel from the gas station under the nozzle when refueling and wait a few seconds before removing the nozzle. Last drive of the year as it turned out as we got half a foot of snow last night. About two weeks earlier than last year.
