Average MPG?
I have seen a couple mentions of folks getting 26 MPG or higher on the highway - I certainly have not been able to accomplish that. We went on a two hour drive, had the cruise set on 78-80 and averaged about 21.4 over and back. Do you have to drive 65 to get the high MPG? (cuz I don't think I could do that!) :o

I get right at 20 in the city and 32 highway.
But I live more in the country to in the "city" is setting the cruse at 50 or 55 and crusing alot of the time untill I get in town where the stop and go begins. on the highway if i set cruse at 65 and instant says 32 but at 80 i believe its around 22 or so... I think it depends on what motor you have to LS2 I believe gets slightly better milage than the LS3.

Depending on the weather I get between 30-34 on the freeway.
On a cool, low humidity day with cruise at 65 I can see 34 (most I ever got before tuning, and intake/exhaust work was around 31)
Typical driving shows freeway around 29 and city driving around 15
21.4 mpg sounds very wrong as I can get higher than that in 5th gear.

I drive 75 miles each way, twice a week, with 50 miles of the 75 on the interstate, with the cruise control set on 77 mph. I get 27.5 to 28 mpg for those 50 miles. My 08 coupe is an A6.
I'm averaging about 15 mpg around town, not exactly stop 'n go driving, but almost.

Now THAT's the way it should be driven 
I drove to Vegas in my 2010 GS a few months ago (~5 hours) and was able to squeeze out 28 mpg at the best. The trip back to Phoenix was much less environmentally friendly, as I found myself accidentally passing slower cars uphill at 115mph a few times

I drove to Talladega, ran the track at 160+ MPH and returned home some 1200 miles and avg'd ~25 MPG(actual, hand calculated). I drove to the Smokey mtns, ran the Tail, etc, and returned home some 2600 miles and avg'd 24.9 MPG(actual, hand calculated).
I don't run enough gas through the car just driving in the city(stop and go driving for a couple of hundred miles with no highway driving isn't my style) to give you a mileage report. The car is a weekend fun car, so it gets a mix of driving conditions when I take it out. I would guess that I'm avg'ing around 21-23 MPG for the entire 15,000 miles that I have had the car(since new).

Everyone needs to use fuelly. Such a great website to track mileage.

I have followed this topic here and on other sites over the years. Just a few observations I have made. Slower is better. Flat landers do better. Lower elevation is better. People that rely on the DIC do a lot better. My DIC consistently reads 1.5 MPG over my hand calculations. That being said: My overall average for the last 16K is 22.1. 3/4 of my driving is rural and the rest is 75 to 80 on the freeway. Stock 6.2. Later! Frank
