Wow 27.7 for the whole 2000 miles or maybe just last 25miles LoL.. Damn.. You have way more self control then me.. I was averaging 27mpg till I hit the break in of 500miles.. Now I am at 19mpg for the life of the car (2593miles) LoL ound:Just turned 2000 miles in my new Vette. Totally satisfied. I have had none of the associated problems that others have encountered. Total miles are about 50-50 town and highwat. Average mpg of 27.7. Top speed reached 125 (when wife was asleep).
I did mine at 2,200 miles.Ha ha you're a rock star. Have you done any maintenance on it yet - oil change, etc?
