Official: What are your real world MPG Numbers

[ErikBEggs]

this is my first "little motor" car, the AC on is noticeable to power if you happen to get to low in a gear. mpg takes a hit in the city from it, so i'd imagine if your running the defroster in the northern states its similar deal.

Nah, there is no noticeable difference between AC on and off. Trust. It may be an incremental increase.. like a fraction of a MPG, but that is something your driving habits will never allow you to notice because it is such a small comparison.

I just broke 15,000 miles on my Cruze, fuel mileage still increasing. I can now hold 38 MPG on the DIC @ 70 mph Cruise control. The number jumps to 45 MPG at 55 mph. These numbers are up about 5 MPG since I got the car and its only rated 36 MPG on highway. This break in thing is no joke.

MPG: 47.6
Miles: 509.0
Gallons: 10.690
Price: $4.009/Gallon
Total: $42.856

Again, 1.4T manual hatchback with trifecta tune and ZZP short ram intake. driving style and route are the same as my last posting.

Not as good as expected

I have the 1.8 automatic, with about 900 miles on it, and around town I am getting about 22 mpg. I know part of the problem is that due to the "grabby"brakes I am not able to drive as smoothly as I used to with other cars. I am leaving on a 1600 mile road trip next week, will see how the mpg is on the open road and if the local driving mpg goes up when I get back. I also hope to have enough miles on it when I get back to really bug the dealer about the grabby brakes, for now everyone says it's because the car is so new. Even with this lower than expected mpg, I still like the car for its comfort and style.

I just drove Houston Texas to Oklahoma. About 450 miles and the cruz set at 60 mph (even in the 75 ughhh that sucked) The DCI read 54.3 and the math came to be 49.8 MPG I was inpressed

The brakes are way overboosted on this car. Another thing is break in. I have 3100 miles and I'm pretty sure it's still not fully broke in. I baby it, big time. But every once in a while I flog it. When I do, my mileage increases about 1mpg. I got 36.72mpg (calculated, not DIC)last night. Up from 34.6. I think I'll need to flog it about 3 more times to get the motor and trans fully broke in.

I'm 1100 miles on 6 spd my 1.4 ltz. I'm getting pretty crappy mpgs. The first two tanks averaged 29 mpg on fuelly (and one of those tanks was all highway). I reset my computer on the third tank and I've been hanging around 25 in the city. I usually shift at or before 2,500 rpm. And cruise below 1500. There's no way that can be considered heavy footed. I'm using 87 E10 fuel, maybe that's the problem. What kind of fuel are you people getting the higher mpgs using? Maybe it needs to be broken in more? I just hope it starts improving soon, or I'm going to take it into the dealership, and I hate going to the dealership.

91 E0.

What's with the 1 and 0 above and below your fuel gauge? Mine is F and E...

How fast is your highway miles?

it is a setting... kinda like binary 1 is on(full) 0 is off(empty) i think europe started this.

It's the ethanol. I did a road trip a few months ago where I ended up in an area that only had E10 91 (I use 93 E0 normally). My fuel economy went down almost 5 mpgs. Once I got home and got that crap flushed through, my MPGs went right back up.

Now that I have almost 5000mi. on her, I've been getting 31mpg (DIC) all city.

 

[laborsmith]

heenico, where are you getting E0, or is the 93 I buy here in Center Line e0 and I have nor realized it?

I am pleased with mpg so far but can not compare as I had the dealer use 93 for the first fill up and have not looked back. One reason I may be pleased is if I have been inadvertently using e0.

[theenico]

I haven't tested the fuel, but based on my mpg results, it's safe to say that most (if not all) of the Mobil stations around us have E free 93. One of these days I may get one of those nifty test kits to confirm my thoughts.

I just filled up this morning and the DIC said 42.2mpg, but my calculations gave me 38.6mpg on 87 octane with the cruise set at 70mph and trying to shift before 2000rpm. I do see brief speeds of up to 80mph during the rush hour(I don't want to be rude when passing asomeone doing 65). I stand by the break-in statement. it seems my motor is built really tight and everytime I get it up over 5k rpm, my mileage increases.

I just put up my MPG descriptions and numbers in the Premium Gas thread.

 

[laborsmith]

Thanks, theenico. That is the brand I started with on the Sonic.

Driving like I am "supposed" to drive, 34.4 mpg
Driving like I "like" to drive, 29.1 mpg
Driving like I stole it, 26.8 mpg.
which averages to 29.68 mpg on 4 tanks so far.

BTW...it's a 1.8 auto hatchback.

This car is fun to drive!

I was using E10 when i got 49.8mpg but i normally get 32-35mpg with my real driving style

This is more in line with what I'm getting but i have the 1.4 Turbo manual. The past few days I have tried a new driving style, shifting below 2K rpm. I am sticking around 30 mpg city driving. The problem with city driving (to and from work) is that it's at pretty low speeds (>40mph) and there's lots of stop signs. I've noticed a dramatic increase in mpgs when I'm crusing at above 50mph. I filled up a half a tank with 89 Plus at Phillip 66. It didn't specify whether or not it was E10 or E0, but I am experiencing slightly better mpgs. Though, I don't know if this is due to my very conservative driving style I've been practicing. It's kind of annoying, because I really just want to zip around in this thing.

I did the 2k thing for a week, didn't seem worth it. Do yourself a favor, and let it rip to 2500.
