I've got a stock 2012 GS and getting 20.0 average MPG. I know this can vary wildly based on your driving habits and location but what are you getting?

BadAV

Most of my driving is relatively short trips in town, with traffic and traffic lights. I average somewhere between 19-20 mpg in these conditions. I have an automatic.

NY09C6

18 mpg but I do not drive easy and posted highway speed limits are 70-75 mostly.

techmonkey

I daily and my commute is about an hour one way 60/40 highway/city.

Oh Boy

To me this is real world city driving at which if anybody claims more than 10-12mpg is total BS.

Stock LS2, A6, most trips are 6 miles and back but some longer, most tanks are right around 20 - 20.5 MPG.

Not So Fast

Manual GS, most tanks are 20 - 22 mpg. Can get high 20's if on long trips and keeping speeds lower.

TorchRedFred

To be honest, I never looked or cared.

I can probably get 19 or 20, I can tell you that the MPG is lower than I expected. It's quite a bit lower than my LS6 car when I had it.

When I am really careful, I might get 18 in all-city driving. But, I love what the car offers, so normally get around 14. It doesn't bother me a bit because I know it is my fault.

In the 07 its around 18 in town.
Highway I averaged 27.4 from San Antonio to Joplin Mo. Average speed was 72mph for that trip. lol

My mixed after 7k miles of 50/50 city and highway is 20.6. I drive pretty aggressive, hit bumper to bumper traffic for ~30-45mins daily, and don't monitor or even care about the mpg to be honest.

On the highway it maintains 29-30mpg @ ~80mph on flat roads. Stop and go traffic is a killer though.

Seems like the MPG sweet spot in these cars is at quite a bit higher speed than most vehicles that like 55-60.

techmonkey

I don't really care much either just better than expected. I guess the highway miles tend to even out my lack of control (more frequently than I care to admit) and the city driving.

techmonkey

To me, that's not city it's gridlock. In this day we almost need another category for mpg estimates. highway/city/gridlock.

Bruze

The gridlock in my neighborhood really sucks . . .

Atomic6

I have put 1,100 miles on my automatic LS3 since buying it last winter. I set the computer to zero and right now my average mpg is 22.9 with mostly highway type mileage. I live in a rural mountainous area with minimal traffic lights.

Ahrmike

16 in real traffic, 25+ on non-traffic highways.

ExxWhy

I must drive way too easy. My computer says 25.6 avg for the 3500 miles I have owned it. I do live in the country, avoid the city. 09 stick

Atomic Punk

16 to 17. and I drive easy and run 100% gas. the real gas nets me about 1 mpg more than ethanol.
