#23 of 67 Re: 2008 Impala Owner Experiences [axinut] by jeff49783 May 18, 2008 (2:39 pm)
Replying to: axinut (Dec 18, 2007 5:35 am) I am the operator of a brand new 2008 Impala LS (fleet owned car). I have experience with many makes of foreign and domestic autos, most recently Ford, Honda, and Mercedes.   I have had this vehicle for a few days and 1100 miles, an would like to offer the following impressions:   1) Fuel mileage - I'm observing the mid to upper twenties (computer provided figures, not mine), and the engine is arguably still not broken in. I expect this will rise. My observations include a spirited drive from Northern Ohio to Northern Michigan, and a dose of E85 thrown in.   2) Fit and Finish - The General did a good job on this one. Everything is tight, consistent, and has a quality feel. There are no squeaks or rattles yet, though I fully expect a few new-car bugs.   3) Design - Visibility is average. Control access and entry/egress are good. the trunk swallowed ALL of my professional equipment and there is still room left.   4) Ride/Handling - Competent, if not above average. It is not a sports car, and it feels better on our lousy roads.   5) Value - This vehicle is a teriffic value for the money. I look forward to a productive relationship and I will report back.   Jeff

Reporting in. Purchased new 7-30-07. all options except sun roof. Great car in all respects. Never returned for any work. I do my own maintainance. Gas mileage since new 25.88 mpg using regular unleaded over 13400 miles. The driving is a mix of hyway at 65 - 70 mph. and some short runs of 5- 8 miles. Ths short runs kills the mileage. I had a 2000 Impala LT with the 3800 engine which gave me 28.4 mpg over 41000 miles. I suspect the performance gearing results in less MPG. In any event, I am well satisfied. The mileage beats my 1972 Monte Carlo 350 CID, 3- speed stick which gives me 17.2 MPG. Enjoy the ride.
#26 of 67 Expect a 30% drop in mileage with E85 by givemeabrake May 24, 2008 (6:44 pm)
One of the main reasons I traded my 2003 Impala for a 2008 was the ability to utilize E85. My in-city mileage was 22.4 with regular gas but only 16.6 with E85. Thats more than a 30% drop in mileage. I am finding that my mileage cost is 18 cents per mile on E85 and 16 cents per mile on gas (for in city driving). E85 is now $3.19 in Atlanta. Only when the price of E85 is 30% less than gas will we break even. Since I have to fill up more often on E85 and it costs me more per mile I am going back to regular gas. I will wait until E85 is MORE than 30% LESS than gas. Replies to this message: quietpro (May 27, 2008 12:19 pm)

Replying to: givemeabrake (May 24, 2008 6:44 pm) Thanks for the info on E85. I am curious if you are driving stop and go or is there more gridlock/idling. Is there any performance increase with E85? I haven't read as to whether the engines are tuned to take advantage of the higher octane. Regardless, the costs outweigh the benefit. I consider myself a "green" person but have not jumped on board with E85. If you look a little deeper, your expenses are higher still once you figure in farm subsidies and tax credits for the producers of ethanol.   Happy motoring with regular unleaded.

Replying to: axinut (Jan 03, 2008 11:15 am) axinut,   I have a similar problem with my compass. I live in the middle of zone 3 and 4 and so i calibrated for zone 4. I recently drove 100 miles south so i am definitely in zone 4 at this point and my compass worked perfectly.   I am haven't tried to set it to zone 3 yet, but will report back... do you think that you are in a weird calibration zone?

#29 of 67 Odd sound in the engine compartment by rwessels Jul 07, 2008 (1:52 pm)
I hear this sound in the engine compartment from time to time. The dealer has put over 160 miles on it and 'cannot replicate' it. So I made a recording and they still say that they cannot do anything about it till it happens.   The sound can be downloaded clicking here (and is annoyingly loud).   Has anyone else noticed a high pitched whine happening occasionally with a pitch that varies with RPM?

Replying to: rwessels (Jul 07, 2008 1:39 pm) No, I don't think so, I was able to set mine by following the instructions in the owner's manual, it worked like a charm. If you can find an empty parking lot or cul de sac it will make the job much easier. Five or six circles should do the job.
#31 of 67 16inch wheels vs 17 inch wheels by sylviae Jul 22, 2008 (1:24 pm)
Please tell me---which size tires/wheels would be the best on a 2008 Chev Impala for the best ride or driving and handling. I was supposed to have 17 inch wheels on it but they put factory 16 inch instead---I am not happy with the dealership not honoring my request in buying this new auto---is there any difference in the ride with the 17 inch wheels and will it give me a better ride???? Please give me some advice. I also requested a 6 CD Changer and got one called an aftermarket---a Pioneer in the trunk and it has to be tuned to an FM signal. Is this the best I can do?????

Replying to: rwessels (Jul 07, 2008 1:52 pm) My '06 Impala developed this exact noise when it only had 7500 miles on it. It is most likely the power steering.   My car had blown a high pressure line in the power steering system, which caused the fluid to start leaking out. There was a TSB for this, so the dealer performed the recommended procedure and it has been fine since (my car is just about to hit 30,000 miles). It is amazing that this may still be an issue in the '08's.   Check your power steering fluid and make sure it is at the correct level.
