2014 Sierra, about to give up on this truck

[jbrianr]

Apologies for all of the sarcastic responses that state get a Sentra, what did you expect, get a Prius, my wife has one, etc. Maturity and internet are strangers for the most part.

 

I digress....... I have a 14 2WD Z71 Crew - 5.3 - Level kit with 285-65-18 BFG KO2's . My previous commute was similar to yours, and my mpg was also similar. 14-15 mpg average. My right foot is also a little on the heavy side. Speed limit is 70-75 on my commute, and I am usually around 80ish.

I have a stock 17 4WD Z71 double cab ... I go 80 on the highway most of the time.  I do a mix of highway and stop-and-go driving, so far I'm getting about 17 MPG.  Usually get about 20 on the highway.  Also have a bit of a lead foot but not too bad.

 

Also you can get a 2WD Z71? TIL.

Depending on the mileage a tune up could be needed also
