martin22 , do you thing there is any truth to the story I've been told that my car needs to get around 10,000 miles on it before I'll start to see anything close to 24 mpg's on the hwy?
 
How many miles do you have on your 07?

Well, that's what they say. Our '06 has 13K now so should be well bedded in and we have no complaints about the gas mileage, considering it is a 5.3L after all!.
I suggest you try to use the cruise control more often - as often as possible.
By the way, beware of jumping ship to a lesser (LS or LT) model. You may get a better mileage but you may be disappointed in the overall feel of the ride and handling compared with the SS which has a different suspension set up. I rented a 3.9LT once and thought it was ghastly.

My '06 SS got over 24 mpg highway on its first tank. As a matter of fact, I've never gotten anything less than 23 (in the mountains) and have gotten as high as just under 27.
 
By the way, the front suspension on the 3.9L is the same but the wheels and tires are different. The rear suspension is slightly different but only to make room for the larger wheels. The ride difference is due to the wheel/tire size difference, weight, and stabilizer bars.

i've had it to the dealer twice now , they keep telling me that they can find nothing wrong w/our car. Keep saying it's not broke in yet. We're a little over 3000 now & still no improvement yet on the HWY MPG. What Octane gas have you been running in it? I might try running higher octane gas, ALways heard though that It doesn't make much difference in MPG's though.

Hi!
 
Lemon Laws vary by State. When you purchased your vehicle, the dealership should have provided to you a booklet discussing your State's Lemon Law and had you sign an acknowledgment of receiving such materials (it is the law here in PA that such occur at the time of sale of a new vehicle.)
 
Here in PA, if a vehicle is declared a Lemon, the consumer has the option of receiving a comparable vehicle from the manufacturer or a full refund of the purchase price and all collateral charges. A deduction is made for the use of the vehicle while you owned it (after all, you did drive it) but the adjustment cannot exceed 10% of the purchase price. The refund is made to the consumer if paid in full originally, or the refund is given to the bank/lien holder if financed. So, depending on the loan, a Lemon refund may be enough to wipe out the loan and let you start fresh (maybe even with some money left over). If you elect the replacement, then I imagine the loan paperwork would be changed to reflect the new car's information but everything else would stay the same.
 
However, PA laws says that if the defect for which the Lemon claim was made does not impair the use, safety, or value of the vehicle NO refund or replacement will be given.
 
In the case of fuel mileage, this would probably not fall under the PA Lemon Law since the vehicle has not had any issues preventing it from being driven or used. The PA Lemon Laws are mostly aimed at mechanical problems that cause the car not to be able to be driven (stalling, electrical problems, etc.)
 
Fuel mileage is such a driver specific factor. It can be thrown off by weather, idling time, tire pressures, accelerating, braking, fuel quality, route (flat vs. hilly), etc.
 
I would suggest checking your tire pressures to make sure they are at Chevy spec. Top off the car with a Top Tier gas and reset your trip meter. Then try to find a 20 mile stretch of relatively flat highway with minimal stop and go. Set the cruise on 55mph and take a round-trip drive. After the trip, immediately fill up again. Divide the miles driven by the amount of gas needed to top off again, and see what the mileage comes out to. If you still see 20mpg or less, then I would say the dealer is definitely missing something. If it comes out to be 24 or better, then the car is probably fine.
 
I have a 2LT with the 3.5L engine. I average 21mpg in my everyday commute (60 miles round trip). I may see 24 or 25 during all-highway jaunts, but when the city driving comes back into the mix the average mileage drops back to the 21 figure. Our area is very hilly, hot/humid in the summer and very cold in the winter. The engine is always working hard in such extreme variances. The sticker said 21city/31hwy, but I average the lower number. Compared to the 13mpg I averaged with my previous V8 SUV, I am thrilled!
 
Also...the dealer should give you a work order everytime you take it in regardless of whether or not they find anything. No work order means no record for you that it was ever looked at. Not necessarily a good thing.
 
By the way, IL Lemon Laws look to be very similar to PA.

The car only had low thousands when I got that mileage, cruise set at mid 70mph range. Drove Interstate 80 in PA, plenty of hills etc. I have a little over 11,000 mile on it and got 23.5 highway mpg in the Baltimore area.

I have a 2007 SS with about 3k miles and found this discussion interesting. I have noticed that the DIC shows pretty impressive instant mileage when the engine goes into 4 cyl. mode
 
Yesterday I drove from my daughter's house in Towson,MD home to Marlton,NJ. I reset the average mpg when I hit the freeway and 90 miles later checked it when I exited and it read 29.7. I drove the speed limit of 55 to 65 and kept a steady foot on the gas,pressing down to almost maintain speed on hills trying not to go to V8 mode too much. The road is not totally flat, but not too hilly. There were 2 stops for tolls and one bridge. The AC was on the whole time.

How do you reset the average MPG? I did not know that it could be reset.
 
I sure wish there was a way for someone to take a pic of their Average MPG readouts & post them on here. I keep getting told when I complain to the dealership that everyone is probably stretching the truth a little bit on the internet!

So are you saying your DIC is reading an average of 20 MPG from the day you bought the car? If that's the case, then I'd be VERY happy with the MPG you're getting. I average just under 23 MPG in my 2000 Impala with the 3.8l engine; if you're averaging 20 MPG and getting V8 power to boot, I'm jealous!!

How do you reset the average MPG
 
When the average fuel economy is showing, press and hold the top DIC button to the right of the steering wheel. It has a check on it. After a couple or three seconds the readout turns to o if stopped. This method resets all readouts.
 
I agree with the last poster. If you have an average of 20 showing after many weeks and/or months, you should be very happy. My overall average is in the low 16's. I find this car to be a real Jekyll and Hyde. Put you foot in it and it slurps gas like no tommorrow, but ease up and maintain 4 cyl mode as much as possible and it does as well as a V6.
