They exist. I think primarily a Japan thing (no surprise…). I havent seen one in person, but seen them for sale or some weird bidet article about all the options you can get. Hot/cold water, his/her’s, blow dry, lights, music, multiple user pre-sets, etc. usually it’s sold as the entire toilet, not an “add-on” option.
Ha, as i was typing that i considered the possibility your car might be a diesel, but decided otherwise….go figure! But ya, as the others have said, there is also diesel stabilizers, but diesel does have a longer life span. Putting a stabilizer in wont hurt anything, so personally, id put it in anyways just to be safe….
Yeah, for the most part. The other commenter is right about that battery, tho. Disconnecting the battery will help, but depending on the type and age of the battery (and temperatures in the storage area) the battery might still not last. Trickle charger might be ideal here, even just a little solar panel for it.
Gas in the tank is another thing. There might be conflicting opinions on how best to handle this, but- I would run the tank as empty as practical, then fill it up completely (so you have all fresh gas) and add a stabilizer. Most stabilizers will keep the gas good for 1-2 years. Best to make sure its an Ethanol stabilizer (like Sta-Bil 360), unless you put pure gas in. Then make sure to drive it a little so the stabilized gas gets into the whole fuel system.
Otherwise, give it a good wash and then a cover for it if you can if it’ll be outside in the elements. Depending on the storage environment, things could still start growing on it, inside and out.

That’s about how i figured it would be…seems like it would be kinda weird to get right, and even then you kinda need that reassurance of a good pat 😆
