I would imagine a older Toyota 4runner with full tank could idle for 3 days in cold weather without an issue. Is that supposed to be a big deal?

Other than that thing of waking up dead from carbon monoxide?
Most cars won’t make for 3 days. My Volvo S60 which is GDI and normally gets well over 30 mpg has a 70 liter tank that’s 18.5 gallons for you yanks. I have a fulltime Bluetooth OBDII transceiver on the OBDII port it feeds a dedicated tablet on the dash with over 100 metrics in real time with one HZ updates. One of those metrics is fuel burn directly from each injector there are 5 so the software sums them up on a one second basis to give grams per second accurate to the gram quantity. That said I idled after earning the engine up to operating temp with a 5 mile drive around the golf course down the road with the heater on full blast and the blower on high with outside temps last night of 18 degrees F it was holding steady at 0.354 gallons per hour in petrol consumption I also was running my XM radio and had my phone pluged into the charge port. Typical set up for running around. 18.5 gallons would last for just over 52 hours of idling at that consumption rate. During the summer with the AC on high it’s 0.46 gallons per hour to idle and I do idle a lot in it F being hot in Texas summers petrol is cheap compared to across the pond in the USA you pay for a gallon what a liter costs across the pond I will idle all day at those prices.
I’m not sure about that.....I carry my furry friend in summer in the south and leave car running locked with AC on at times 30 min or more
V-8 truck.....V6 motors rarely do much better I’ve found
You can see the needle has moved ....around half gallon or more an hour I’m told
Smaller displacement vehicles like four cylinders burn around .35-.5 per hour at 700 rpm which is on the low end of normal
I do think you could get 30 hours at least on a reasonable four banger
