Zl1 fuel mileage
 

Took the zl1 on a little getaway with the wife for our 14 year anniversary. We drove from Rochester NY to Fallsview casino in Niagara Falls Canada. So I reset the mpg gauge. I averaged 18 mpg there and back. I think that’s pretty good for the zl1. Considering my 2018 grand Jeep Cherokee gets 20 mpg s. What is everyone else getting mpg?

I'm making about 730whp and i get 22mpg's on the highway and prolly around 13mpg's city

That’s damn good.

Mine is a auto with 538 rwhp. There where a lot of cars on the strip. I lot of dodge’s one hellcat redeye, a hellcat, some srt8. I did see one black looked like a 15 Camaro with a radical cam reving the hell out of his motor.

That’s a good number considering the EPA highway rating is 19.
I am not sure I can get 18mpg on mine. I can’t keep my foot out of it long enough.

On another note, my 2019 Suburban has gotten 21mpg/highway . That’s pretty good for something that size.

For those that think I am not doing my part for the environment, my work car (DD) is a Camry .

I drove it on cruise set to 75 most of the way. No spirited driving.

if I really try, I can get it to creep up near 17MPG, but then I get bored and remember how much fun it is to have lower MPG..

45k miles on my 2013 M6. On the highway I have seen 20+ mpg with the cruise set at 70mph.

So far lifetime average is 15.5 mpg.

Yeah, it’s not fun to drive using the cruise control. But the wife was with me and she doesn’t like me driving recklessly. When she’s Not in the car I drop the hammer

You know I never really paid attention to it. My last road trip I may have averaged about 15.8 or something like that. My car is stock but with low mileage so I may not yet have my best mpg.

Highway driving at 80 mph on e85, I get 18 mpg. 750+ rwhp thru 4L80e. I imagine it would be better if I still had the TR6060 and used 93 octane.

I imagine the tuning plays a big roll in how much mpg’s we get.

No. What's been quoted is what it is. 18-20 on the highway and less in mixed and city

2013 M6 MPG
 

for the 2600 miles I've had it, I'm averaging 16.2mpg. Best I've seen for a tank is 19.7. Lowest is 11.8, which was a bunch of rush hour traffic. Which is why I don't drive it to work generally.
