6.2 fuel milage?

[goosedowner]

Thinking about getting a 1500 with the 6.2 engine and I was wondering what you guys are getting for fuel milage. My 2011 is averaging 14 for the life of the truck. I can get up to 22 mpg on trips but around here the hills kill my mileage.

People claim on this forum to get roughly equivalent to the 5.3's.

I have the 2017 sierra slt dbl cab with 6.2 liter 8 speed. I am averaging about 17.5 in town stop and go and the best I have got on the highway is 25 mi to the gallon.

Lifetime average over 23K miles of 16.2 MPG. Travel 60% highway 40% city. The heavier Toyo RTs have knocked off 1.5 MPG over past 7 months. Truck is a 2015 All Terrain 6.2 Crew Cab Short Bed.

No idea what kinda city people are talking about when they say 17-18, but its in the middle of nowhere I can promise that

It doesn't sound like the hills are killing your mileage on that 2011..... You are doing much better than most people I know with that year 6.2.

[truckguy82]

This is what a stock 6.2 gets, no bullshit forum numbers, 21-23mpg highway, 12-13 actual city driving.

I have a 2017 High Country with 3700 miles, and I average 18.6 mpg , mostly city and I use 89 octane fuel, it is better than my 2014 5.3, can't complain

[dmorrisL86]

2017 Sierra 6.2 A/T, bone stock other than a undercover tonneau. I average 17-18 in the city commuting to and from work in stop/go traffic. My 50 and 100-mile averages on the interstate are always 21-23 mpg. I run 91 octane, 93 when I can find it.

How are yall getting 17-18 in the city. I average 13-14 when I am heavy on the pedal and 14-15 when I am babying the pedal. Driving around town is about 95% while 5% is freeway. When i took a 1000 mile road trip, I did get about 21 mpg.
