It is listed in the manual at 18.8 gallons. I have not gone below 1/4 tank in this car.

18.8 gallons according to the manual, but yeah I've never been able to put more than 16.5 in if I fill when the light comes on.

Typically I don't let it get past 1/4 tank, bad for the fuel pump.

377 miles so far, and a lifetime fuel economy of 11 mpg according to the app.

I'm not too concerned about fuel economy for this car. It's just a toy (and a damn fun toy it is!). We have other vehicles for daily drivers. I certainly wouldn't complain if the fuel economy went up, though.

3200 miles, 16mpg. Mileage has dropped a bit since the break-in was completed (no surprise there!). Still better than my Hemi Ram, however. Of course, I don't drive either one of them to optimize my fuel efficiency...

I'm going to add that it's remarkable how radically gas mileage will vary with this car based on how heavy your foot is.

I mean...yeah - it's common sense...go faster, accelerate more often, use more gas....but the difference between "good mileage" and "bad mileage" in this thing is remarkable!!!!

I can get 22 mpg pretty easy going down the highway...18-19, if I take care around town. But the second...literally the moment I decide to have a little fun, I'm lucky to get 12 or 13.

But then....fighting for the highest mileage in a ZL1 is sort of missing the point, now isn't it?

But I bet that your average was way below that when you were putting your car to 70 mph , one can't do the average only at 70, fill the tank drive till you need more gas and then make the numbers , that what you call average , right ?

1,600 miles when I put 200 more HP to the tires that's when it went from 12 to 6 mpg Lol!

That's how I do it. It compensates for driving style and location. Those are the only numbers you can trust.!

17!

Still in break in :(

And I baby it right now, after I did the ring-seating exercise.

[pumpkinrancho]

4500 miles now. Average about 19 on the highway if I keep it under 85.

[Aquabluetoo]

i don't worry about it. I am just glad I have a great car!

[BrazenBeast]

I was getting something like 5 - 7 mpg during my track days last summer. I was getting around 19 - 20 on the highway though.
