What's it cost to run A/C with or without radio per hour just waiting around?
I know in econobox it's cheap, like 1/4 gallon per hour even in Nevada desert heat.... but what about our V8's??
V8 idle fuel efficiency
I would say that the fuel efficiency at idle is a dumb question You are getting 0 MPG's at idle Not very efficient But then again I guess it is important to some people to know just how much gas they are wasting by sitting and letting the vehicle idle
Plus to many variables to get a true answer Idle RPM's Fuel Pressure etc.
But if its a matter of life or death to know the answer then I would suggest that you invest in a precision flow meter to get a accurate reading
Or if its also that important to know the answer then just don't sit and idle and waste fuel
It's not a diesel. It's really not a great vehicle to run long at idle.
I have a scan gauge 2 on my 2007 Expy. I was curious about this too. I have found it runs about 7 tenths of a gallon an hour at idle.
