2014+ Gas Mileage (MPG) Topic

LOL I took those pictures when I got home from a trip from Huntsville, AL to Gatlinburg, TN a few weeks back.

Almost identical to mine... Nice

 

This was my 500 miles drive home from the dealer. Very impressed

6.2 High Country 4X4. I could not be happier with the fuel mileage. My previous 2013 Crew Cab 6.2 was NOT even remotely close.

Man we are just about identical! That's awesome! I freaking want that Denali gauge cluster and red dash lights in a bad way :-)

I've gone back to 87 octane after 12 or so tanks of shell premium with no better fuel economy. Just got the fire update yesterday so I'm curious to see if there is any difference, but the weather also turned warm so it will be hard to say if it was the update or the weather if fuel economy is better. Lifetime of 14mpg with 11000kms, 75 ‰ highway. Dealership now agrees it's broken in and something seems wrong.

WTF...I love looking at my truck...hate driving it. On the suggestion of someone here I reset the 25 mile average and watch that...I'm coasting down my road right at 14mpgs....not touch the break...turn into my driveway...roll 30 feet....hit the breaks place in park and the mpg changes to 13.5.

 

Today on the way to work driving down the road...in V4 mode...13.5 mpgs...13.6 mpgs...13.7 mpgs...13.8 mpgs...13.9 mpgs...14 mpgs...then all of a sudden still in v4 cruise set BAM!!!!!! 13.5 mpgs!!!!!

 

My truck can't even decide if it's getting better or worse!!!!!

I rarely reset mine, it's always just showing the last 25 miles anyway. With the recall all of my bests were reset. The 25 mile looked really good and got a best of 18mpg on the way home, above freezing temps and driving like a grandma, but has settled back to about 14mpg after driving 120 miles or so after the update. Similar to when I first got it, fuel economy went gradually downhill. I get worse on the highway than in the city as most of my city driving is freeway.

I'm still breaking the truck in. 5.3 with 3.42s

What do you mean by 3.42's? Please educate. I'm new to the truck world. Ty

You are going to have some serious rake with a lift like that..

What would you suggest? 2 Inches in front and 2 in back?

3.42 is the differential gear ratio.

I had my truck tuned by Diablew, finished last Saturday with my WOT tuning. I've since put roughly 160 miles on the latest ECM update. My fuel trims are settling in and I'm beginning to see much better fuel mileage. currently I'm getting 17.5 over the 160 miles but my mileage over the last 25 miles has steadily increased (currently at 18.2) All city driving with an occasional heavy foot. My DoD is turned off, no more V4 and couldn't be more pleased.

 

During my tuning process, I removed the third cat, replaced my fake magnaflow(MF)18" with a MF 14" and had 3" pipe ran thru-out. I'm sure the exhaust/cat removal combined with the tune are contributing factors to my increase in fuel mileage.

The back already sits roughly 2.5" higher than the front. Most people only put 2- 2.5 in the front just to level it out. There is a huge thread on this in the accessories section.

How much did that cost you can I ask?

 

Also drove to work today 40 miles. I averaged 23 miles on the trip and my best 25 miles was 25.8 miles.

I paid $485 here . That included the intune and custom tuning by Lew. The $485 is good for a year with free updates if you add a CAI, exhaust etc... after that there is small fee.

Like TDT said. If you want to level it there's a thread dedicated to leveling kits. Look at some of the pics in there and decide from there. If you want something bigger look at lift kits. Usually lift kits are going to raise the front an inch or so more than the front.

Does anyone have the 5.3 with 3:73's? Mine is on order and I'm curious on what to expect for mpg.
