Let the engine get broken in first, and if you still have those #'s then something is wrong or you're not doing something right. I get 27mpg on the hwy and that's using A/C on hilly roads. New engines are very stiff and need to be broken in.

 

Literaly the exact same here. 16.9 driving around town and stuff in DS or manual mode. When I first got the car it was only 16.5-16.7 but that was with no mods. So i think the exhaust and intake could have helped some. Or I just do a little more hwy driving since i've come to college.

 

last fill i got 23 mpg..im averaging 22 though. my driving is probably 70-30, highway-street. ~900 miles

 

10.1

How could i fix this? Stay under 3K rpm for a month? lol.

 

I usually get 16~17 for an average.

 

I get 19-22, depending on if I take local or freeway more. Car's not even broken in yet, haha.

 

Almost 800 miles on my G37x coupe, and im getting around 18 so far. Should I expect this to improve?

 

After 1200 miles now averaging 19.1. MPG. 50-50 highway and street driving. Liking DS mode so it might drop

 

Yeah I was a lil worried too but thats cuz I just got my g37x. 350miles and I avg 15 MPG. I'm pretty sure once I break in the engine, I'll see improvements.... it better

 

The first 500 miles on my car, I averaged around 14 also. Once I hit 1000 miles, I started to average in the 20s.

Give it some time. If you are still averaging 14s after 1000 miles, then theres something wrong or you drive constantly at redline.

 

16-ish is what i get on average. intermittently soft/moderate driving, mostly aggressive. 70% street/30% freeway.

 

15k on the clock, 350 miles max on the gas, it sucks!

 

~350 miles on car.. basic suburb driving as I'm Mr. Mom this week and have my 14 month old in the back(car is a week old). Averaging 17.8 MPG accordig to the read out... that is with normal acceleration, no pedal to the floor etc.

 

22k
16 mixed driving

 

during the first 1000 miles I was averaging 15-16 mpg. Now at almost 3k it improved to 19 mpg
