ltd coupe. I don't baby it and the worst I've ever had was 20 in the city and the best was 25 highway on a cool crisp day. I have no complaints.

 

My first tank in the 07 SE roadster with auto trans, 26 mpg, on what I assume was premium filled by the salesman, but who knows?
I think he must have pumped it full as it took a while clear the full mark, and my filling didn't take so long to start going down. I'm just over 500 miles now odo and I'll see what I get when next purchase.
Most driving is country paved two lanes, state highways here in Michigan, and paved secondaries, at 50 mph since we've had snow most days and didn't seem prudent to floorboard her.
I see diminishing gas mileage in the spring.

 

This is my daily driver and Ive been getting 22 - 23 consistently with every tankful. The one time I got below 20's was when I did a lot of driving with the top down.

 

Hey Cal, do you have any mods? Like a K&N filter or cold air intake, or anything like that? I don't know how you're getting such good mileage, but consider yourself lucky!

 

I average 22 with a mix of city/highway. I got 25 on a roadtrip to dallas where I was going between 65-75.

 

No mods....just stock SRT6 but driven gently in the slow lane during San Francisco commute traffic. Some rare occasions late at night where I can floor it and get up to 80 or 100 briefly before letting off but that should not impact my gas mileage that much per tankful. I think 22 - 23 is average from what I've seen posted.

 

My best is 28.4 in last summer, cruising. Have hit 25s and 26s pretty often on long drives. Driving hard, but for more than 120 miles I get 23-25. Average daily commuting, 7 miles each way, drops me to 20, sometimes 19. Never had less than 19. Never expected to see anything above 24. After getting into 28s several times I decided I could drive this baby the way she was designed to be driven. Since I've never driven her to see the best I could get I wouldn't be surprised to get into 30 with a long distance econo drive. I'll report back if that ever happens.

Feel free to ignore my response...I didn't notice that it was an SRT6 post. My results don't factor into this thread. Apologies to all.

 

28+ mgh drafting vehicles on California Hy 5 noth of Sacramento.

 

I just got 22mpg going from Chicago to Detroit this weekend. Doing about 85mph when I wasn't in Chicago rush hour.

I was surprised as hell.

Considering I get about 17-19mpg during DD to/from work.

...I have a feeling that will be getting worse since getting back from Eurocharged...cause it is waaaaayyyy more run to romp on now haha.

 

My wife and I just got back from a 1000 mile trip to Canada and back. The first fill was 28.5 MPG, the second fill was 29 MPG and the last was 30 MPG. The last was all highway miles with the cruise control on. Most of the way, the wing was down - I was driving slower than 62 MPH. By the way, my 2007 base coupe ran flawlessly!

 

Round trip Edmonton( July 1 to 4 th weekend) via Waterton,Glacier park, Kalispell Montana, and back to Edmonton via Radium and the Ice Field park way, 2150 km /1350 miles
193.45 liters =11 km to the liter,or
30.62 miles to the imp gallon,
altitude ranged from 2500 ft to 8700 ft

 

my srt gets a consistent 21mpg city, haven't been on the hwy much to get any numbers there but i reset the tripmeter every time i fill up and have always gotten 21-22mpg city... pretty good I think given that I enjoy listening to the exhaust.

 

I had a trip from NC to Florida I got 30 mpg. Of course my intercooler was out of commission so that was a trip without the SC... To bad we can't put a kill switch on it for roadtripping.
