That is correct. Even though it's a different trans (same, just reprogrammed) I think that MPG numbers for 2012s might be discussed in here too. I am consistently getting 12.5 mpg average - calculated after filling up as I don't have the EVIC. This is 99% city driving. And since it is winter I am using a ton more gas since I am sitting idle waiting for the temp needle to move. On the coldest of days it takes about 10 mins for the needle to move. Usually I sit there 5-7 mins. It's usually blowing some warm/hot air after about that long. Living 2.5 miles from work has advantages.
Best avg mpg was 14. 30% of that tank was used on highway and a road that is 55mph but had stoplights on it too.
Looks like my 2012 is doing about the same as most of you.
I would be interested to know if the trucks have 4wd or 2wd, not the trans.
It would also be interesting to know if those of you that are using a tune that requires 93 gas have calculated if it is even worth the higher price gas with a little higher mpg or lower price gas and a bit lower mpg running stock. My guess is the difference is negligible
