    I did this myself, unintentionally of course. I inherited a car but didn’t have a driver’s license, so the car stayed on the driveway for roughly a year until I got around to getting the license. I did do some minimal maintenance on it - every once in a while I’d go out and start the engine, I moved it slightly back and forth in the driveway to ensure that the wheels weren’t always in the same position, and I trickle-charged the battery once or twice when it wouldn’t start.

    The car seemed to come out of the experience perfectly fine. I needed to change the battery about another year later, after I’d been driving it a while, but I’m sure that’s just because the battery was super old to begin with.

    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.

      Disconnecting the battery will help avoid the possibility of corrosion seeping into cables. It’s probably not a huge risk in the span 12 months, but it’s an easy precaution.

        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.

            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.

        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….

    Only three things I can think of, two of which have been covered already:

    • Battery, ideally disconnected.
    • Gas, ideally add a stabilizer.
    • Tires, tricky, ideally you’d move the vehicle every so often by 20-30 cm to even the load, but worse case your tires are going to wear out quite a bit quicker after a year standing on the same spot.

      Since you gave advice on the battery and fuel:

      Tyres go bad through the vehicle’s weight, so either raise the vehicle enough so they don’t touch the ground, or remove wheels and put it on stands.

      Once you make sure the car is secure release the handbrake so it’s not engaged for a long period to prevent it from fusing.

      Clean thoroughly inside and out to make sure dirt doesn’t adhere to paint or seats, that no food is left inside the cabin that can go bad and smells that can embed themselves in the seat foam etc.

      Cover with a car cover to protect seals, paint, seats from the elements.

    One thing no one has mentioned is the brakes. Do not apply the parking brake because it can actually become fused on after a long period of time. The best thing to do is actually remove the wheels and use jack stands. If you don’t do that then use chocks.

    Before driving it you will want to bleed the brake lines to remove any air that might have gotten in there, and ensure the brake fluid reservoir is full.

      The brake lines are hermetically sealed, there’s no way for air to get in.

      The biggest problem is rust on the brake discs; they will still work but often need replacing due to rust pitting

          That’s true for diesel. First gen bio-diesel was hydrophilic to make that even worse. Absolutely fill up the tank before leaving it over winter.

          Gasoline keeps evaporating and essentially only breathes out until the tank is empty.

          Exactly this. The ethanol in gas absorbs water from the air and turns into weird nasty gas tank sludge.

              It’s possible in the US, but generally not at common gas stations. You have to find marine or airport gas stations. The only other place I’ve ever seen it is a place called Sheetz.

                Actually I’ve seen more and more gas stations start carrying no ethanol recently. It used to be extremely limited and the biggest chain I knew of that offered it was Phillips 66, but now the top 3 chains in my area offer it.

        Disconnect the battery. Don’t leave gas in it. Make sure you’ve got proper antifreeze mixture in the coolant, if you’re in an area where winters get freezing. And if you can, get a proper car cover.

          Alternatively fill the tank and use a storage additive. Like this stuff https://www.sta-bil.com.au/products/sta-bil-fuel-stabiliser.

          Dont just disconnect the battery, take it out of the car and put it inside, on a battery tender if you can afford it. Put 1 or 2 of those closet dehumidifier tubs in it as a precaution against mould (especially if its been rainy in the leadup to storage) and if you’re relatively smart with cars go into the fuse box and take out the fuse for the ecu/fuel pump so that if someone breaks into the house and finds the keys they cant just steal the car.

          Also yes, DEFINITELY get a cover that fits well. Poor fitting covers can really damage the paint if they move around too much.

          Even when disconnected, car batteries will self-discharge at a rate of 5-15% per month, so after an year, the battery will likely be drained completely.

          @LemmyKnowsBest@lemmy.world, what you could do is buy a solar trickle charger for your car battery, it’ll help maintain the charge level. They’re fairly cheap and good option, as long as your car (or panel) is exposed to sunlight.

          Another issue is that your tyres will deflate. Typically tyres deflate around 1-3 PSI per month, or maybe more during summer or in hot climates. So by the end of the year, your tyres could be deflated to 3/4th their capacity. To solve this, you can get a portable air compressor, which can be powered by your car battery (which is hopefully still charged!).

    Biggest thing to know is what sort of climate are we talking about? Extreme heat and cold are big factors. As well as sitting the thing down beneath some big trees or in a very dusty place.

    I’d make sure it’s driven every couple of months or so.

    With a moderate climate the gas and tyres are probably fine for a year. And the battery is probably fine if it’s left disconnected and charged up again before putting it back in service. But a year is about the limit, after that the chance of the gas going bad, the tyres getting out of round and rubbers drying out is high.

    In a more harsh climate, things can go bad much sooner. Probably better to sell it and buy another one, once you need it again. If for example you are going away for a year or more.

          About 1/2 as bad for it sitting. Rubber will rot a lot quicker with weather than just dry heat. You’re talking about a constant heat with no moisture vs an humid heat + water + cold cycles. It’s a lot worse on rubber than dry desert heat is.

    You’re going to get critters inside if left in a driveway.

    I would store it somewhere that is kept rodent-free annd climate -controlled. Also, check with your insurance as you could drop collision since you won’t be driving it.

    If you have a military base near by you’ll find storage options. Also look for rv storage facilities as they probably store normal vehicles too.

    If you store it outside and put a car cover on it you’ll come back to lots of small scratches in the paint and rodents.

    It might make a big difference where this residential driveway is. A Los Angeles driveway that’s got a shade tree by its southern side, you’d probably not want to cover the car. (And you’d want to be extra aware that our air eats rubber.) In places that get much hotter and/or colder and get more rain/hail/snow/leaves falling on it, the benefit of a cover outweighs its potential to attract rodents.

    Gas might go bad and battery may lose charge but other than that it should be fine. Ideally you should start it atleast once a week and let the engine reach normal operating temperature, but nothing catastrophical is going to happen even if you don’t. Just more engine wear because of the lack of lubrication.
