: How much fuel does our engine use when idling?

Preferably with the AC on. Gallons per hour or cc's per minute or something like that.

Hmmmm, tough question. From one who has idled it a lot, I can say this. You could maybe go a day if you had a full tank of gas. Maybe 1/4 tank after 4-5 hours? So let's say in my experience, maybe under 1 gallon per hour.

Looking back on our 2005 hurricane evacaution where we spent half a day idling and crawling, I think I used about half a gallon per hour (or perhaps just slightly more) in a 2.7L V6 engine in my S4. An engine twice the size seems like it should use about twice as much, which would work out to your estimate of about a gallon per hour.
