mileage

I fully understand that most people couldn’t care less about mpg with the Stinger. However, I really like the fact that the Stinger has all of the power I want but only when I want it. I can simply flip a switch into ECO mode and I can get what is actually rather impressive gas mileage if I am...

Been noticing that the fuel mileage is steadily improving. I just took a 3 hour trip to St Louis and I was getting great mileage. Wondering about everyone else. I've got the 3.3L GT2. How does this compare to the smaller engine?
