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.

Psst…im in your inbox…feeling the same dread. (Please dont reply, i might not be ready for another reply yet 😆)

AFAIK, Batteries in pokemon cartridges were only for the in-game clock, not the actual save files! So he is not safe!

Edit: i stand corrected! Ive never had or worked with pokemon carts specifically, but i have worked with & modded a lot of GB, GBA and N64 carts and not all of them have batteries, in fact most dont. I know n64 mempaks do, tho, but almost none of the carts. Info i had gathered from the various retro communities led me to believe that GB/GBA pokemon carts were a type that didnt need a battery for the save file, only the clock, but apparently that isnt always the case!
