2003 Impala gas mileage




By man1 - usenet poster

" "
I bought a 2003 Impala with the 3.4 engine six weeks ago, and just passed
500 miles, almost all city driving. My third tank of gas gave me 17 mpg,
which I find disappointing. My neighbor with the 2001 3.8, whose praise of
the car helped me make my decision, says he's getting 26 mpg with the same
kind of driving. Is he just trying to drive me insane? Is this a break-in
issue? The EPA puts city mileage at 21. Your comments, or comparative
numbers, are welcome.

My 2001 impala 3.8L gives me 17-18mpg and that is 80-90% city miles.
One time I got 21mpg and the worst was 16mpg.

I own a 2000 Impala LS with the 3.8, and when I commuted to another city for
work, it consistently got 23-24 (with air conditioning on). Now it is used
for heavy traffic town driving, and its lows range from 17.9 to 19. On
highway trips its best has been 33 with no a/c. One recent highway trip at
75-85 mile per cruising with a/c on netted 27.5.

My 03 Tahoe is rated 14/19 . I am getting 11.5. My 01 that I traded in got
18 easy enough. All the other 03's that I have checked are gettin 15 city
and 18-20 hwy. I have went around with Chevrolet on the local level,
customer assistance level. Now I am at the third step, setting it up for
arbitration.

For mixed driving commute, I average 19-20MPG with my '03 Malibu 3.1 V6
engine (rated 20-29). I haven't had it on a road trip yet. When I drive
the same commute with my wife's '03 Dodge Stratus 2.7 V6 engine, I get
24-25MPG (rated 20-28). If I use my '97 Grand Caravan with the 3.3 V6, I
average about 18-19MPG. The odd thing is that the Malibu is the lightest of
the three at 3100 pounds vs. the Stratus at 3300 pounds and the Caravan at
3600 pounds, yet the Malibu gets essentially the same mileage as my Caravan.
Not sure why I can't even achieve the minimum "rated" mileage with the
Malibu, yet can average somewhere in the middle of the rating range with the
two Dodges (which one would expect). The Chevy dealer says my mileage is
normal...I don't think so, but what is one to do? I will say that I agree
that the 17MPG you're getting with your Impala is disappointing...especially
having to fill up three times just to go 500 miles!!...I've gone farther
than that loaded up on vacation with one tank with my Caravan (25-27MPG
highway with a 21 gallon tank). I will say that your mileage will probably
improve as the engine runs in...I was only getting 16-17 for the 1st couple
thousand miles on my Malibu...so it is a little better than it had been.
Based on some comments in the Malibu NG (alt.autos.chevrolet.malibu), it
would seem that the most recent engines are not providing nearly the mileage
that the ones made a couple of years back were providing. One posted that
he routinely got 32 on the highway with his '01 Malibu 3.1 until the engine
had to be replaced to fix a severe piston slap problem and then got much
worse mileage after the replacement (I don't remember the number). So, it
wasn't the driver causing the difference in that case. Makes one wonder
what is going on with the newer engines...doesn't make sense!

I get 27-28 every week consistently; this is 75% highway, 25% city. (Houston, TX).

Are you sure you're calculating this right?

My 2001 Impala LS with 3.8 gets excellent city mileage. I just filled up
tonight, and got almost 23MPG. My dad's 2001 Malibu with 3.1 is consistant at
21MPG all city driving. BTW, my ol'trusty 91 LeBaron 3.0V6 has been the MPG
champ since new. It has NEVER dropped below 25MPG around town, and one time is
averaged 34-35MPG on a 2000 mile round trip between Tucson and San Jose.

I have a 2003 Impala with the 3.8 engine. With about 1,000 miles on it, I
checked the mileage and it was a little over 24 mpg. That's a combination
of city and highway driving, mostly highway, as I commute to work in another
town.

I'm not through my full 2nd tank yet, but right now I'm at a quarter full
and about 200 miles on the trip.

Maybe your foot is heavy?
