After 1400 miles on my R/T I'm averaging about 17mpg. At least 1000 miles are highway.

Sorry I didn't see the older thread. But anyway it looks like we could use more information on how much the Charger "loosens up" after breaking in.
I'm also curious about how much the octane affects gas mileage. I've been using 87.
