Never really checked mine. My guess would be 10-12mpg or worse. Seems to go through it quickly. And, high test is $3.09 a gallon here in February. Can't imagine what it will be after Memorial Day!

Hey Sarienbarry........ Go play in traffic will ya!

 

I've always planned to check the mileage on my 427, but somehow I never get to it when I fill the tank. I'd guess it's around 10 mpg in town, but not really certain. Never get out for many road trips, so can't even guess on that.
