2019 6.2L MPG

[Taz56]

2019 AT4 - 6.2L

Came stock with 18" wheels, I put on 20's. Also added the GMC cold air intake, GMC Cat-Back exhaust, Front end level kit.

 

I only bought it in July so it is 5 months old now.

I have 25,658 KM's on my truck (15,943 Miles)

Lifetime 14.1L / 100KM

Current 13.4L / 100KM

I only put Premium fuel in it.

 

Converted is:

13.5 liters per 100 kilometers equals	21 miles per gallon
14.0 liters per 100 kilometers equals	20 miles per gallon

What tires did you put on the 20’s?

 

between debating keeping my 18’s with duratracs for winter and get 20’s with summer tires for the warmer months in alberta.

Can you run E85 in the 6.2 or is it like the K2 version where its not compatable?  

No the 2019-2020 don't run on E85 with the 6.2 or the 5.3 stupid move by GM.

Ditto the "stupid move" comment. I wish they had not done that. I liked running E85 in my 2014 Sierra All Terrain.

So still beefy AT tires.  Planning on doing a trip across canada so im looking to improve my fuel mileage.  So i should be able to do better then 13.4.  Best i got was 9.1/100kms so far, but that was cruise set to 90kmh.

Hate to burst your bubble chief but 14L per 100km is 16.8 mpg. No where close to 20mpg

Ok, "chief" I got that from a conversion site I didn't just make it up off the top of my head.

But if it is wrong it is wrong.

I’m getting the same mileage as you. But I leave it in mpg. And the dash shows 16.8-17 mpg. Also the google conversion gives the same as my dash reading.

Cool

It's probably 16 miles per U.S. gallon and 20 miles per imperial gallon.

I have a '19 LTZ CCSB (4500 miles) 4x4, 6.2/10-speed, performance upgrade pkg., max towing pkg., and factory 20" A/T tires. Gets around 16 mpg around town in traffic, and 21-22 out on the road. Averaged 19.8 mpg on recent 120 mile round trip with mixed driving on rolling hills (60 miles of back road driving, about 15 miles of 50-55 mph, and fairly heavy traffic the rest of the way). Truck runs on Shell premium, but living in the NE we get crappy "winter gas" that hurts mileage. That same exact trip with "summer gas" averaged 21.2 mpg.

 

If you like to hammer the throttle, the mileage will suffer in a hurry. Same goes for remote starting. My wife averages about 3-4 less mpg than I do, no matter what the conditions are.
