Alright, I want to see if anyone can beat my average over a long mile average. Like 1k+ miles.

'15 GT, automatic, with 3.15 diff.

No doubt. That's pretty good but when someone asks me what kind of mileage I get my standard answer is:
Who cares? I didn't buy the GT for fuel efficiency.

That is very true, although I'm poor, and this car costed me about 10k more than i make in a year, lol. So i'm cheap by nature. It's my daily driver and I wish i could have an alternate as to not wear it out so fast.

They make new pistons every day, so why worry?

I've seen as high as 30 mph on a 200 mile trip even with the supercharger, truth be told if I womp the crap out of the loud pedal it's typically around 22-23

I can get close to 30 on long drives at 70-80 keeping around 2k rpm. When I'm heavy on the pedal I go down big. Like 14 - 16 in a 15 mile playtime.

My daily ride to and from work is about 21-22 15 miles each way Highway. Getting on it when getting on and passing, cruising at a good clip (7AM).

You get really good mileage with your rig, I wonder if the supercharger makes it more efficient even though its more power?

I would imagine that this is the case. The effeciancy of the engine should be increased with aide of additional air according to most of the theory that I've read, this is a hard thing to actually confirm real life as it's so hard to keep the throttle in the "responsible" zone lol
