    Leaving your car idle

    Leaving your car idle 16th Sep 17 at 10:56 PM
    Hi,

    What happens if you leave your car idle ? By that I mean if you don't use it at all for a while and not turning on the engine and leave it running- so leaving the car unused for say a month - how will the car deteriorate if not used?

    thanks,

    habib.

    I bought a 3 year old Kia last month, I went on holiday for 8 days, came back and had to buy a new battery as it died in my absence!

    Also had to jumpstart my TT this morning as it hasn't been driven for a few weeks, just starting up the engine every few days obviously wasn't enough

    The usual rule of thumb is that it takes 15 minutes or so of running to replenish what the starter took out of the battery. So if you keep starting the car, running it for less than 15 minutes and then stopping it again, the battery will eventually go flat. If you start the car at all, it should be run for long enough to get the engine fully warm - 20 minutes or so. This will drive moisture out of the oil, engine and exhaust.


    For me, up to 3 months I would just leave it in gear with the handbrake off and keep the battery charged regularly. A full tank of fuel would help to prevent moisture condensing in the tank and contaminating the petrol/diesel. Above 3 months and I would be thinking of a proper lay-up routine.
    An hour alone spells freedom to the slave.

    The battery on the Kia could have already been poor, 8 days idle with a healthy car and battery shouldn't be a problem.

    Starting the engine every few days on the TT is probably why the battery was flat.
    Don't harass a hippie. You'll get bad karma.

    I`ve one on both my vehicles and they do the job of keeping battery power up.
    If all fails don`t lose any sleep over it just scrap the car and get another
