2004 Dodge Neon SXT - poor gas mileage

I have a new (< 3000miles) 2004 Dodge Neon SXT (auto trans.). The
sticker said the car should be getting 25-31 MPG. Unfortunately, I
have yet to get anything above 22-23 regardless of my driving
(city/highway/etc).

Being a new vehicle, I don't expect it to be a problem with spark
plugs, O2 sensors, tire inflation, etc. Is there anything else that
can be checked? I fear a trip to the dealer would turn up empty since
22mpg is "close" to 25... however, a previous car with the same rating
easily did 28-30 on average with the same useage and I'd like to
regain something close to that.

Could this really be something as simple as 'heavy-footing' it? Or is
there are potential underlying problem? This car is a bit more
powerful than the last (a 2001 Saturn), so I suppose that could be it
(my wife is quite the lead-foot from a stop..)

Thanks.

 

Unless its hard for you to get to a dealer, I would take it in, this is part
of what you're paying for when you buy the car. Understandibly, with a new
car, you wouldn't expect wear-out problems with the spark plugs, 02 sensors,
etc,. but you might find that something is defective. Some new Chrysler
owners ran into problems with defective spark plug wires on their new cars,
for example. Also, you might try different gas stations, with the high
price of gas, some stations might be selling crappy gas.

No, the sticker said the car rated 25 mpg on the EPA's simulated
city-driving cycle, and 31 mpg on the EPA's simulated highway-driving
cycle. This does NOT mean the car "should get" that mileage! The EPA test
protocols are slightly more representative of real-world driving
conditions than they were in the '70s and '80s, but not much -- there's
still a very wide gap between how the EPA computer "drives" the car and
how any actual human being does it on actual, real roads.

By all means, have it checked out in case there's something wrong, but
don't think that the numbers on the sticker are any kind of indication or
guarantee.

Check the tire inflation yourself and don't just assume they are correctly
inflated. Cherck the maximum cold inflation rating stamped on the tire
sidewall and inflate to somewhere between that setting and the one stamped
on the door jamb plaqcard. Too low inflation will destroy your mileage as
well as permanently damage your tires.

I assume your trying to get this mileage at 55MPH on the highway. If you
are doing any stop and go or doing 75MPH, then your mileage will suffer (but
this seems to be too excessive given your numbers).

One last comment and that is that when the engine "breaks in" (10-15K miles)
your highway mileage should increase by about 10% from when it is new.

A heavy foot can certainly reduce your mileage by >10 percent.

with less than 3000m on it, would you expect this motor to be fully broken
in yet?

MPG's should start to increase as the rings become fully seated.

How exactly are you measuring the MPG?

I have a new (< 3000miles) 2004 Dodge Neon SXT (auto trans.). The

I've got a 2003 SXT with about 10,000 miles on it and I get the same mileage
as you. I only drive in the city though.

 

Driving conditions. driving conditions, if you had a problem with fuel
consumption the EPA dude in the dash would let you know. trust me

The wife averaged 29-30MPG (mixed driving) and mid 30's (highway) on a 1997
Neon DOHC "Sport" she used to own.

Today we both average 25-26MPG (mixed) and about 30ish (highway)...her driving
a 2003 Stratus 2.7 V6 and me driving a 2004 Sebring 2.7 V6. I would certainly
think that a Neon that is 600 pounds lighter than a Stratus/Sebring and with a
smaller engine should do better than a V6 Stratus or Sebring.

Here is another kicker. Our 1997 3.3 V6 Grand Caravan averages 19-21
mixed...25-28 highway.

So, there is a problem with your Neon or your wife is driving it very hard.
I'd take the car back to the dealer to check it out.

 

that 31mpg is calculated at 55mph are you doing more?? how does it shift??
does the torq. converter lock up ??
and i think it's time we reinstate that speed on freeways again
so we slow our oil usage and price will drop, supply and demand ya know

 

Gasolinequality also varies by region and can affect mileage.

 

I had a '98 Neon with the 150 hp 2.0 L and an automatic. It never got
anywhere near the advertised milage. Milage was right around 23 mpg.

My 2003 gets about the same mileage but is only rated at 132 hp, 2.0 L SOHC,
automatic. Did they downgrade the horsepower for the later models ? I've never
tried a different gas station, only used the one I've gone to for the last
several years. Maybe I should switch and see if it improves my mileage.

Mileage drops about 1.5 mpg with AC on btw.

At one time they had a DOHC 2.0 150 horsepower for the "sport" model and a SOHC
2.0 132 horsepower for the standard highline model. My wife has one of the
1997 sport models wit a 5-speed. She drove it hard and still averaged about
29-30MPG mixed and 36-38 highway.

 

My 2003 Sebring w/2.7 got about 21-23MPG until it was fully broken in. I
get 25MPG now.

 

Yep -- my '98 R/T got comparable gas mileage. The 5 speed made a huge
difference over the 3 speed automatic.

My 2001 R/T gets about 27 mpg mixed, and my wife's '95 Voyager (3.0 L
w/ 4 speed auto) gets about 20 mpg, mixed or highway. These are both
close enough to the EPA estimates IMHO.
