Proven Mileage tips?

[Thymeclock]

I'm at 7k and my last fill up was only 25 mpg. I track it religiously and have not gotten up to 30mpg yet. I know my car is new still, and it takes time but my previous vehicle was usually getting 33 mpg so its kinda a shock to the system when instead of 400 miles per tank, I get barely 300.
I've seen on ebay and stuff about the engine chips......any one have any luck with those or is it all just crap?

Do you have an automatic? If so, I suggest you read this thread: viewtopic.php?f=49&t=27350

It has nothing to do with the car being new. The fuel economy is not going to improve as the car ages.

I read the thread Thymeclock. thanks. I understood most of it. lol.
That sucks. Have you gotten any results from your efforts to get an update from GM?

I have responded to them and left voice messages to the rep they assigned to my complaint, but my phone calls were not returned. It looks like they are vying for the 'worst customer service of the decade award'. That gave me ample reason to send additional complaint letters to those higher up in the chain of command recently, addressing their non-responsive disregard of my initial complaint. (It appears that GM has more head honchos in its ranks than the US military has generals in its Army.)

I expect a courteous and timely response from them. I shall persevere.
