So if its 2-3 higher then the actual does that mean I am only getting 20-22 MPG with my 1.8 auto?

That's about my experience. Seems like the first few hundred miles are not as good.
My mileage on a flat highway at 65 is 38+ (1.8 auto). Most of my driving is on county roads and neighborhood streets with hills. Averaging 28+...

I'm sure the PCM learns your driving habits too and tailors the motor to it. I noticed my 2nd tank was a bit better too. Plus the whole "dont stay at 1 constant speed for to long" during break-in doesn't help. As everything gets seated right in the motor it'll do better too.
As far as my manual 1.8L indicator being accurate, so far it has been pretty close. 28+ and likes to hang in the 29's

I finally have some real commuting tanks of data, 4 tank average of 33.0mpg
60-70% city, I've been driving easy and short shifting. Last tank was 89 octane, this tank is 87
Want to see how it goes?
Overall average is still higher because of 4200 mile roadtrip...

i just drove 412 miles from houston to OKC. It said on the dash 42.1 mpg yet the math said 36.56 mpg ... it started out saying 46 mpg on the dash when i was driving 60ish last 200 miles was a steady 74 mph... still happy i just don't like the fact the the dash is very modest always reading too high....
We've always found it hard to calculate mileage on one fillup, by math, in any car. The amount of gas that the tank can hold can vary so much by the way each pump nozzle is set to cut off. If you "top off" the tank it can take another gallon or so to make the results vary widely.

Hi all -
I just got a hatchback LT, 1.8L engine. I like the car a lot except for one thing - thus far the gas mileage is a bit less than stellar. I picked the Sonic over the Accent because I liked the car as a whole much more even though the fuel economy isn't as good, but I didn't expect to be only getting 20MPG. So far I've been doing city driving in pretty heavy traffic, as I'm in suburban Maryland. I'm trying to coast as much as possible, break over a distance, etc., but I just cannot seem to get this puppy much above the 20MPG mark. Any thoughts/suggestions?

I started really shortshifting about halfway through the last tank and with about 95% city and suburb driving I calculated 34.4MPG.
Welcome!
Is that 20MPG on the car's readout or have you checked it at the pump? What kind of car were you driving previously and what kind of mileage did it get in the same driving?

It's on the car's readout, and I'm still on my first tank. And this is actually my first car, so I have no basis for comparison.
I do make shorter trips instead of longer highway commutes - I know it starts to creep up when I'm driving at night and can go longer stretches without hitting a light. I'm sure all the stop and go traffic has an impact. Still, though, dipping into the 19MPG range for city driving seems really, really low.
I would reset your avg. display and start fresh and see what you can get mpg wise. Also, you stated this is your first tank of fuel, so I would give it this tank to be well into the break in process. Also, unless I missed it, you didn't state what transmission you have? Keep us posted, because 19mpg isn't acceptable. I bet your number will improve.

Ahh, OK. Well, in pure stop and go city traffic it's tough to get any economy, especially on the car's display. In this scenario you are idling and accelerating quite a bit and this really brings down your average. This is also the first tank and the car is still breaking in, so expect a few MPGs lower than normal.
Also, the display will not show instant MPG on the highway, so if you get on a stretch of open road it will take a while for the average economy to creep up to what you are actually getting, especially when you've been driving a while in really heavy stop and go traffic.

elisabess, you did not mention any freeway driving, but as part of breakin you will want some extended miles at good speed. This may or may not help your mpg but it will help your engine.

It's the automatic. We'll see how the next tank goes, and how things look on the highway.
Yes elisabess, make sure you get some highway miles at highway speeds in your breakin period.
I got my Sonic in Dec and am absolutely loving it overall.
LTZ Turbo Hatchback
However... I'm not getting anything over 32 mpg both on the display. At first I thought it was just the computer being a bit pessimistic but I'm not getting anything more than that at the pump either.
Usual driving is about 70/30 City/Hwy driving, so I didn't think too much of it.
A weekend roadtrip put about 230 miles down with consistent speed of 65-75 and that didn't move the fuel economy much past 32 if at all.
I generally don't drive too aggressively, 2k rpm on the tach at the most, am aware of the 6th gear, etc... so...
Any ideas? Am I doing something horribly horribly wrong?
