A new-ish, well-maintained vehicle with new tires, fresh oil change etc, if it's left dormant & undriven untouched in a residential driveway for 1 year, will it be driveable after 1 yr?

okay you mentioned a lot about gas and stabilizers, what about diesel? My vehicle runs on diesel.

Diesel keeps better that gasoline but there's differences between grades of diesel aswell. I'm a prepper and I contacted a local dealer to ask about how long their diesel keeps and they told me that because their diesel doesn't contain any organic compounds(?) it should be fine for several years but ones that do might start growing algae. I re-fill my canisters once a year.

Diesel typically has a longer shelf life, so thats one benefit. A year, under optimal conditions. I believe you can still buy stabilizers meant specifically for diesel.

Thank you

I would highly recommend you do not drain the fuel tank, you should leave it with a full tank to minimize the amount of room for moisture in the air to condense. Too much moisture in your tank can cause it to rust from the inside out if it's steel.

I would also fill it with rec gas - gas containing no ethanol. The add gas stabilizer.

It's a diesel engine, but that's excellent advise for anyone with a gas engine that comes across this post!

Definitely add diesel stabilizer. It might not be necessary, but it's not expensive, and better safe than sorry

There's an algae that grows in diesel. Whatever additive you get make sure it's got a biocide in it.

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….
