Probably more like 70 to 75 but its not like I'm running the crap out of her. I could get 28 to 29 in my 01 monte with the 3.8 if that tells you how I drive. I don't know maybe this one is just poorly tuned. I've been running 87 octane since I bought it a month ago could that make a difference?
if you want better mileage, go slower ... that simple :p
and for gods sake, please put 91 or higher in her ... unless you get a tune for 87, you really are going to do more damage than what the 25 cents a gallon is going to save you over the long term ... the KR demon is going to get you eventually and you will not like the outcome ... but then again, if you dont care about having to rebuild your engine due to detonation, by all means run 87 in it ...
if you dont want to put premium in her, buy another car ... that simple

if you need any proof, just ask lew ... lewtune ... i forget what his actual screen name is ... but he can tell you all about what it actually can do to your engine over time
these cars can be tuned to take 87, i believe but are not meant to take it ...
who knows, maybe thats why mine had so many problems, because my stupid brother very rarely put 91 in it and used to BEAT on her ... i ran 91 the ENTIRE time i had the car almost 15,000 miles and had nothing but problems ... could very well have helped it start to fail, if not having caused it directly

I'm getting about the same highway as this member stated. City, around 14-15. Intake and mufflers didn't do a damn thing for me either. I'm always running premium 91+.

Just took my car to the shop yesterday to have an oil cooler line, as well as a trans cooler line repaired. I also notified them of oil consumption, 1 3/4 - 2 quarts per 2k. After contacting GM, dealership informed me that GM is aware of the consumption issue, and that they are in the process of addressing it; the "fix/parts" are being produced. They documented the issue and advised me that I will be notified when the new "fix/parts" are avaliable, even if i'm out of warranty, (due to documentation while under warranty)... They said it shound be 3-5 months? I have no idea what parts they are talking about; perhaps there is an issue with the rings and seals?

That seems excessive. How many miles and how much oil was it burning?
