Replying to: quietpro (Jun 11, 2007 2:11 pm) We did have a guy last night , who saw us in a parking lot & came over & checked our car out , he started talking to my husband asking about the cars MPG, my husband explained the car was only getting 20 on the HWY, & that they sticker showed 27 for HWY. The guy said if i bought the car I'd really be on to them about only getting 20 for the HWY. Not for sure If I explained that the 20 HWY MPG was driving on the interstate w/ very little braking & normal acceleration. It's getting pretty much the 20 HWY MPG on the interstate as well as driving through towns on the hour long trip I take to Springfield or Pekin. I can't understand why it's not doing at least somewhat better on the interestate w/little slow downs at stop lights like I do going through the small towns I have to go through.

Replying to: teresabutler89 (Jun 26, 2007 12:48 pm) I'm getting well over 20mpg on the Interstates around Champaign in my SS and you should be too. Two things: Are you sure your engine is switching to 4 cyl mode? It should stay in that mode when cruising at 65 - 70 mph on a level road and the indicated mpg should range between 25 and 30. Also, what RPM are you showing at 65 mph? From memory as I write, it should be just under 2,000. There is a remote possibility that you're not reaching overdrive top gear. Hope you get your problems sorted - it's a great car!

Replying to: martin22 (Jun 26, 2007 1:54 pm) WHen you say well over 20 MPG's on the highway, what are you varying, if you don't mind me asking? I've heard that several other people that have these SS are also getting better than we are I just can't understand why are car is not, I know it's very disappointing & I love the car's looks, power , safety & comfort, but the MPG's is killing us coming from a 06 Mailbu getting around 30 MPG'S on the HWY. The sticker showing the 27 MPG's is what sold us on the car, so I'm depressed over this MPG stuff. Thanks I hope they figure something is wrong w/it & fix it so it starts getting better MPG's on the highway. What's really crazy is that it's doing about the same maybe around 18-19 for the city mpg's .

Replying to: martin22 (Jun 26, 2007 4:27 pm) So far we've got 3,000 on it. I got something set up for a second look over on this car. I'm hoping they come up w/someting this time. Last time which was only 2 wks ago, they said they could find nothing wrong w/the car. Thanks for your input. Glad you like your car & are getting pretty descent HWY MPG's , wish I had your car. Is it a 07 or 06, which color did you get? Did you get the Bose speaker package? We have the Bose speakers, silver trim on Dash, not the woodgrain. Has a sunroof. It's a beautiful car, just wish for better MPG.

Replying to: quietpro (Jun 25, 2007 8:47 am) I know it's not because I have my foot into it or anything, because my husband complains that I drive like a grandma w/it that I should be driving it differently just because it's the SS. I drive like I always did w/ our 06 Mailbu, sometimes on the interstate I'll find myself getting up fast 75, but even when I did that w/the Malibu I was still getting 30 MPG's. So if anything Maybe I need to try a higher octane gas? I'm running out of ideas, maybe the service dept. is just not finding out what's wrong w/this car. I'll give them another shot, & if things do not improve I'll try taking it to another dealerships serive dept. I hate doing that though because I didn't buy the car from them, so I do not know how that works when you want to go to another dealership beside the one that we've purchased the car from?

Replying to: teresabutler89 (Jun 27, 2007 8:26 am) Wow...you read my mind...those were the two things I was going to suggest next. Higher octane fuel and another dealership. I was running 87 octane fuel exclusively for the first year I had my SS simply because I could and thought it really made no difference. Then, I got to thinking about how little it would cost and decided to switch. Well, the difference in power (once I had fully gotten used to driving the car with lower power) was truly remarkable. Besides that, I have noticed on the highway, with the higher octane, the car can remain in 4 cylinder mode at higher speeds and on steeper grades which contributes to higher fuel mileage. I don't know that it would be enough of a difference to justify the difference in cost or whether it will improve your situation at all, but it's worth a try. In my case, I haven't had a chance to take a long enough road trip to get a good comparison but I do know that my car can stay in 4 cylinder mode in places it couldn't before and at higher speeds than before. As for going to a different dealership, I have visited three different dealerships with mine. I bought my car out of state so I have only visited the dealership where I bought the car a couple times. All dealerships should treat you equally well and if not, you should contact the corporate offices and report them. GM is making strong efforts to improve customer relations and you shouldn't have a problem with a different dealership. They SHOULD welcome your business as an opportunity to win you over for your next purchase. Again, just be polite, don't bad mouth the other dealership, and explain your problem. One final suggestion would be to offer to ride along with a techician to show them the sputtering you've been describing since you say that the techs have said that they haven't been able to duplicate the problem. Sometimes communicating the problem is the hardest part of the process and if you can get them to let you drive them around and then maybe switch out let them drive you back you may both learn something (you mentioned you weren't sure if it was engine or transmission). Good luck and be persistent and patient. I'm sure you'll get to the bottom of this. The SS is a great car. Once you get your bug worked out, you're going to love it! Give it a fair chance.

Replying to: garsarno (Jun 24, 2007 3:32 pm) DId you already have around 10,000? The service dept. keeps telling me that I have to let the car get to 10,000 miles on the odometer to see anything close to 24mpg on the hwy. I trying to find out if this is true, if everyone else didn't get around 24 mpg's until 10,000 miles.
