I think I saw 67mpg once when I reset it while on the highway and off throttle. It lasted for approx 10 seconds till the computer updated and spit out 20mpg. But it was fun while it lasted

 

^^^ Bwahaha

Honestly I barely ever switch to that option on the trip computer... I know what I signed up for when I bought my Z... mpg was definitely not a selling point.

 

Typical 7 mile drive to work each day in a 07 coupe grand touring - up to 80 mph in short sections of of the drive for an average of 18.3 mpg (see that reading all the time). Average speed gauge says 28 ish mph. I have seen 23 mpg when I baby it and use less than 35 hp the entire drive to work - monitored with the torque app and kept under 70mph with steady smooth pedal use. If I stay around 60 mph tops I can squeeze 26 ish mpg with fresh less than 300 miles on a oem air filter with 93 octane in the tank.

 

under 400 miles on a near tank. Probably 350-60ish. 19.8 avg mpg reading since i bought her 6 years ago (according to the computer).

 

the mpg computer is very accurate

 

I average 17-18 mpg. A lot of city and spirited driving. I am never worried about gas because if I was I wouldn't have bought a z lol.

In a roadtrip I took I got 33 mpg, and it was accurate. All depends on how you drive.

 

mine is 17.7, but before it was tuned it said about 18.3. the tuner said i was running really lean so it makes me wonder if all the people getting high mpg are lean or all hwy miles

 

I average about 23 mpg city and highway combined.

 

Na bro you just have mods, your mpg starts to go down with more mods

 

yeah that too, and a heavy foot. now that you said that i think when i got the car it was right around 20 or so mpg
