Just put the OnStar app on my new phone. At 7200 miles it says my lifetime mileage is 36 MPG. Even if that's off by 2-3 (which it likely is) I'm more than happy considering the vehicle I was driving beforehand was in the 12-16 mpg range.
Last few tanks have been between 35-36 mpg, with the gauge creeping up with the temperature (currently reading 38.1)

My commute is mostly 45mph with lots of turns and hills. I'll get an average of 41mpg on my way to work and 43mpg on my way home from work. My best highway MPG was about 44mpg and on about 100 miles on the trip, my DIC says 41.3 so I'm guessing about 38-39mpg average.
I don't drive like a granny, but I drive conservatively. And I do like to take it through the gears every once in a while.

Man, am I the only one not seeing these gerat mpgs? I'm at about 1500 miles on my 1.4 turbo and I'm only seeing averages of 29 and below. I drive an average of 10 miles a day, if just travelling to and from work, and more on the weekends. My average speed is below 40 and I do have plenty of stop signs on the way to work. I'm sure that has a lot to do with it, but even on the weekends when driving across town and whatnot, I'm still only seeing averages hanging around 29-30. My last fill up was with Phillips 66 89, and if anything I've been experiencing lower mpgs than 87 e10. I also feel a little more hesitation when I accelerate with the 89 ocatan. I'm not complaining too much because my old vehicle only got about 9mpgs, but I'm just kinda bummed I'm not getting the kinds of numbers that more of you are seeing.

I also do about 10 miles a day at similar speeds, and get about 32 average. Only have 5 stop signs to deal with, and one light.

My average on the display was 35.7 before today. Today I fueled up, re-set the tripmeter and the computer for her first real highway miles. I fueled back to full after 260ish miles to see what's up. Display read 45.5, mileage by gallons was 43.7. It was a trip to Beaver Creek and back from Denver-ish, so all mountain miles averaging 65-70. She pulls the mountains really well too, never having to drop lower than 5th.:banana:

According to Fuelly, my last tank was 28.5 MPG. The DIC was reading 28.7. It was almost all city driving with much of that being stop and go traffic and a lot of short trips. I also used the air conditioning some. That's really impressive mileage for that type of driving.
Yesterday I took a trip down to Castle Rock and back and the DIC was reading around 38 MPG. That was with the air conditioning on and going 75 MPH for much of the trip up and down some steep hills. Even if that is 3 MPG optimistic, that's meeting the EPA figures despite being run much harder than their tests.

have a 1.4t manual hatch. put in k and n 33-2510 air filter, and some less restrictive intake piping. with conservative driving the dic reads 50 on the highway after 20 or 30 miles. average 40 around town...pissing off a lot of people who are apparently in a bigger hurry then me along the way...lol. combined after a week of mixed driving, dic reads 42.4. lovin it:banana:
if you want more details on the mod send me a message. as for manual drivers, shift just at 2 and no more when possible. the turbo motor has enough low end torque for this type of driving

I know what you mean about pissing people off, when I decided to drive it "normal" to get best mpg, i was getting passed like i was in reverse. But I was in the right lane unlike some people!

Hi sipNzipHatchT, yeah, we have talked about short-shifting on several other threads. I try to always shift at or below 2000 rpm and use the low-end torque of the turbo. There is another thread I posted on Brake Specific Fuel Consumption (BSFC) that explains why it's more efficient to keep it at low rpm and higher throttle input.
Some people don't like to "lug", but I don't think it's a problem.
At these low rpm's, the intake flows are relatively low(even with the turbo spooled), so I don't know if an airfilter and intake piping make any difference. Did you do any pressure drop testing before and after the mods?

I don't go over 60 mph on highway since I'm still breaking-in the car, and I average about 45 mpg on flat ground, about 39-42 mpg in hills. I get about 33 mpg driving in regular traffic or neighborhoods. I shift @ 3000 rpm in 1st and 2nd gear, then 2000 rpm in the other gears. And if I'm driving at 50 mph in 6th gear, the DIC shows about 58 mpg

2012 six speed turbo in 800 miles of mixed driving averaging about 34.5 miles per gallon couldnt be happier.
