stuck in a car with the engine running (not me btw)
just listening to snowmageddon on the news about people getting stuck in cars on the motorway…was wondering how long would a say….1/2 a tank last (30lts) with the engin running to keep the heat on.
quick google failed me but tbh this place is usually better than google 🙂Posted 6 years agosingletrackmindMember
I think most engines burn about 1 gallon per hour at idle .Posted 6 years ago
You dont need to run an engine constantly to keep a car warm , probaly only 15mins on / 10mins off something like that .
All depends on CC’s and petrol or diesel , outside temps and windchill factorsbigGMember
I was stuck in my car in the snow of December 2010 (20hours to do 21 miles), much of the time it was stationary and I never turned the engine off.
I started with a full tank and when I got home I’d used substantially less than a 1/4 tank. So I guess idling in a diesel doesn’t use much fuel at all.
I was knackered and flipping starving though.Posted 6 years agoZedsdeadMember

It is nowhere near this. The engine is not under load. If you were burning one gallon every hour at idle then you would be burning many gallons every hour whilst in use.

20 years ago people got stuck on the M62 and several died of hypothermia. I didn’t understand at the time why people didn’t run engines to stay warm. I also didn’t understand why they didn’t knock on a few of their fellow drivers’ windows and arrange to share cars to stay warm. But they didn’t – and some of them didn’t see morning.Posted 6 years agomr_millsMember

Because if the engine isn’t under load for a long period of being stationary it doesn’t give enough heat and your heater won’t blow hot. So if you’re planning on being stuck in a car overnight, take lots of spare clothes, like I didn’t.Posted 6 years agoRustyNissanPrairieMember
idling engines for long periods of time does them no good-the bores glaze due to to not enough loading on the crank
Good point. Better to die than glaze your bores eh
if its forecast bad weather/snow pack some warm clothes/sleeping bag, a diesel wont generate much heat anyway if its idling unless its got a fuel burning heater (FBH).Posted 6 years agoPaulDMember
I have had mid-size petrol engines using 1 Litre per hour at idle, but this doubles if the air conditioning is on (not fan-speed dependent) and the ambient is >4C.
A 2L diesel used approx 0.1Galls/Hr (I know, mixing units, but I did not make the car computers).
So, 30L fuel should run for approx 24hrs unless you keep revving and moving only a small distance.
