I average 22mpg and I use it as a daily driver 18 miles each way to work, mostly highway.
Just got back from a 600 mile round trip and averaged 26.5 on the way up through PA. For about 50 miles I followed a sheriff van doing 80-90mph (got 3 videos of it).
On the way back to VA, averaged 26mph.

Very happy with my mileage, especially since my V6 got 20mpg.

22-24 here, though my driving is mostly highway. Probably drive 80% highway and 20% in town. Car is bone stock aside from SLP loudmouths and a Hurst short throw shifter that were both on it when I bought it. Did one tank running errands in Tulsa and it fell in the 16-18 range.

I'm averaging 17.78 mpg after 8 fill-ups. Car is an 05' Vert Slushbox with 52K miles, and bone stock with 3.31 axle ratio.

This is about 60 miles a day driving composed of ...

- 25 miles highway with No Traffic
- 25 miles highway Horrible Traffic
- 10 miles Stop and Go

If I drive pure highway, I get low to mid twenties, but any stop and go driving and the fuel economy drops big time.

Computer tells me 17.5 with mostly city driving and very little highway driving. I dove to Ocean City about 100 miles from home and got it up to 19.8. All stock 4.6L.
