This topic is for Impala owners to share and compare their actual MPG.   "Real World" Fuel Economy vs. EPA Estimates Replies to this message: steve333 (Oct 27, 2007 7:25 pm) quietpro (Oct 28, 2007 2:19 pm) thegraduate (Oct 29, 2007 12:48 pm)
#2 of 117 MY MPG by 02impalals Jun 02, 2005 (9:07 pm)
I bought my 2002 LS car used from one of the well known rental companies. it had 27500 miles May 03 on it and it now has 37k.   but my MPG has been fine.   Average 22 mpg Low 19.5 high 26 median 22   I only use regular 87 octane gas and mostly 76. Most of the dirving is in the city with Stop/n/go. Ive never taken the car on a road trip where ive used a whole tank of gas. But recently ive been getting 25 mpg with mostly city driving and going to school 2x/week. (approx 20~30 min drive 40~60 mph on freeway depending on traffic condition).
#3 of 117 Utah MPG by axel7 Jul 18, 2005 (1:44 pm)
I get about 23 mpg religiously. I have a 2001 STD Impala w/ about 87k miles. No leaks, no squeaks, nothing. My only complaint is that I am upside-down in the loan, probably like most people.

2003 Impala 9C1 police package, 3.8 V6... 41k miles when I got it, has about 65k (had it about a year)... I get about 22-24 around town... mostly about 23... I've gotten about 29-30 before on a trip (all interstate driving)... I was happy with that...
#5 of 117 MPG on 2003-04 Impala ? by michel4 Jul 21, 2005 (7:14 pm)
I am seriously considering purchasing a 2003 or 2004 Impala with the 3.4L engine. My question to you owners is,   WHAT SORT OF GAS MILEAGE ARE YOU GETTING?   Please specify what year and engine size you have and whether you are giving highway, city or combine mileage.   I will really appreciate your response!!

Replying to: michel4 (Jul 21, 2005 7:14 pm) I have a 2001 Impala and it got 33 highway and 30 city brand new. Now it has 144,000 and gets about 26 highway. Not sure about the city.

Replying to: michel4 (Jul 21, 2005 7:14 pm) I have a 2004 Impala base, bought new Dec. 04 and now has 20,000 on it. I get 29-31 typically on the road, up to about 33 for the best; in town I get in the low 20s. I use brand name gas and occasionally fill with premium or mid grade. Coming across S. Dakota, Wyoming, and Montana where the only gas available was corn gas, 85.5 octane for regular, I got about 2-3 mpg less. Highway for me is 65-85 mph. I keep the tires at about 35lbs. I did my initial oil and filter at 1,000 miles. Last oil change I used synthetic and I plan to continue with synthetic oil, changing about every 5,000. I run a K&N air filter.

Replying to: michel4 (Jul 21, 2005 7:14 pm) I bought a 2004 Impala with 8100 miles on the odometer in Oct 2004. Engine is the "base V-6" (3.4 liter). In my case I get no where near the EPA rating (no surprise there) which is 21 city and 32 highway. City driving gets me only 16-18 mpg and so far one trip has given a high of 26.3 mpg, however to be fair, most of that was mountainous with many upgrades and downgrades, so the tranny was shifting up and down most of the way. I am, therefore, assuming a trip across level interstates might return a 28-30 figure, but that is only an assumption at this point. So far the car has been reliable, has good performance and is smooth and quiet. I carry 32 psi in the tires, and change oil and filter at 3,000 mile intervals. My use of gasoline is generally wherever the price is lowest and I have noticed NO difference in performance or mileage regardless of the brand of gas (always 87 octane) used. It's a good car, but if mileage is important I'd consider the Malibu which is lighter and more fuel efficient. (I also understand the Malibu V-6 gets better mileage than its 4 cylinder counterpart).
#10 of 117 Real World Mileage for 06 3.9 3LT or LTZ by jfcnet Feb 18, 2006 (11:11 am)
Howdy, I'm in the market for a new Car. I tend to buy the engine first. I currently own a 2001 pontiac Grand prix GT. I has the 3.8 L 90 deg. V6. In the real world I get about 23 city and about 28 hwy. I love this car, It is a great combo of performance and economy. Plus it's durable I have about 197k miles on it and still going strong.   I have driven the impala 06 with both the 3.5 and 3.9. I like the power with the 3.9 however I'm concerned about the milage Being a Gm/domestic buyer with 2k on my Gm card I will definately buy some gm product. So if you own an impala with either the 3.5 or 3.9. I would like to here about your (after breakin milage)   Thanks   Jfcnet (el Paso,tx) Replies to this message: zjim (Apr 23, 2006 11:42 am)
