V8 averaging 16+ mpg
I've got just shy of 3000 miles on my V8 Treg. I commute 61 miles each way to work - 1/2 highway, 1/2 backroads. I'm averaging a little over 16 mpg so far.
I have been consiously using the cruise control on the highway to try to improve mileage - I generally cruise between 70-75 mph.
On another note, while 91 octane gas is called for, I've been running the lasat few tanks on 89 octane (mid grade, rather than premium). I haven't noticed any performance diffs, nor valve pinging. I'm figuring it'll save me probably $400 / year in fuel costs.
Hope this is useful
