Racing the local kids? Lol.

I have no complaints on mine, for how heavy my foot is, lol

I got 12.4 out of this last tank. I think that had a lot to do with changing the TPS and cleaning the TB. Since I didn't go have the pcm re-flashed, they said it could take upwards of driving it for 100 miles. I've put over 100 on it and it does seem to be running normally again.

Dis 840 miles this week in my Silvy. Had to got to Seattle, then down to my mom's old place to do some repairs.

I had an average speed of 78, had cruise set at 80, and averaged 21.1
My lifetime average for 47601 miles is 15.0

Not too shabby IMO, considering all the loaded miles. My 2009 HD had a life average of 10.3 at 65K when I traded it. LOL Much fewer loaded miles

Not much better than 12mpg with a more aggressive tire tread and the fact that it's been pretty damn cold out.

I've been averaging around 11.5 mpg.

About 12ish with all the recent -40 and heavy foot, lol

So far 18mpg on the new Silverado. Can't keep my foot out of this 6.2L

The longer I had my Sierra, the heavier my foot got, and the worse the mileage was. There towards the end, I think I was getting 13-14 in town.

So far I am averaging 19mpg, mostly in town freeway with some city.

Sure beats the 13 I was getting with the same exact driving in my GMC.

I switched my tires back for the summer and got 15.2 mpg the last tank. I'd imagine summer fuel has replaced winter fuel by now as well.
