My new M6 V6 is hardly sucking any gas, I am shoked, I reset the trip computer leaving the dealer earlier, I put 130 kilometers on the car since and I only smoked a quarter of the tank. at this rate, I can do 500 kilometers per tank. Yes, I am aware it;s 68.0 liters, but it aint all that big. I must be a really good shifter, driver, or this is a one of a kind green car, and it's new, I'm wondering if the fuel mileage is going to get even better. And so far all the driving has been city driving.
