I averaged 23 on my last trip in my 18 Zl1 manual with the cruise set on 85 most of the way on a 1300 mile trip each way. I just sold it 3 weeks ago to buy either a new gt500 or A10 Zl1 not too sure rn. I got back from a 6500 mile round trip yesterday I took (3weeks Houston to San Jose Ca- Seattle Wa back to Houston) in my trackhawk which was a pure blast but only averaged 18 mpgs lol. The Zl1 was just as comfortable tbh and it would have been a flip of a coin to favor either or if I still had my Z. Tbh mpg’s are last thing on my mind. The fun factor is priceless.

I have the same exact truck I had in 2010, verse a 2012 now. The 2010 got a confirmed 2 mpg better than the 2012, Weird...

I've seen 27mpg as well, 73mph on cruise control from Knoxville to Nashville (actually when I bought the car and was driving it home) on I-40, but that trip is coming down off Cumberland plateau and it exaggerates MPG. The opposite trip would probably be 23-24 at best.
