    Been googling and stuff coming up is in gallons and all US related.

    What I'm looking for is a ball park estimate of how many litres a 2001 Hiace might consume with the engine running idle for an hour without any lights/fans/radio on ?

    Basically battery could do with a decent charge, don't have a charger and would prefer idling rather than needlessly drive.

    Youd be better off driving, as it's generally not a good idea to leave a vehicle by itself idling and youd be bored shirtless sitting in it.

    My car shows 1.2 litres per hour if sitting idling.
    I think you would be better driving it to charge to be honest.

    Very, very little. Put it this way, I can drive my car for an hour at 100kmph covering 100kms obviously and it will use about 5 litres of diesel which costs about 6.50 euro.

    If your van burned even close to a litre of fuel I'd be surprised.

    Agree with the above, extended idling isn't good. To answer your question though, probably 5-600ml an hour.

    About 20 years ago a friend went out for a few pints on a Friday night. It was a cold night, so before his last (yes he was going to drink drive) pint he decided to go out and start van and clear windscreen.

    Went back to pub and ended up having a few more, forgot about van and went to nightclub.

    He spent Saturday on beer to.

    His little black 205 van was lovely and toasty lunchtime on Sunday. Tank must have been near full on Friday

    Thanks guys. Gather from above that fuel consumption is much much lower than driving for same time.

    Guys aren't fans of extended idling I see. Presume main reason for this is risk of theft.

    And while battery charging may not be as effective as driving I gather it should be good enough

    Would you borrow a charger off someone?

    Bit of a waste of fuel / emmisions...

    You are right of course. Will buy one as soon as get to a decent sized town. Live out in the sticks

    Yeah, what's the Craic with this? Is it just the risk of theft or is there so reason not to idle I can't seem to figure out?

    Well idling from cold to heat up a car/engine has another problem, it increases wear. Basically from cold the ECU, the "brain" of the car runs the fuel/air mixture rich on the fuel side to keep it running and get it up to temperature(and to prevent detonation). Basically like pulling out the choke in the old days. More fuel going in remains unburnt and can get past the rings and into the oil reducing lubrication. Bore washing I think they call it? At idle oil pressure is low too which doesn't help either. So from cold it's much better to just drive off as the engine will heat up more quickly and oil pressure will be higher and you'll get less wear and tear on components over time.

    Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things. If you’re not aware you’re stupid, you probably are.

    Look, this is an Irish soultion to the problem (read dumb as) just drive the van and get a new battery, and disconnect the battery when you sit the van up for another few months.
