Denali and Rst owners with 6.2 engine state your mpg

[Jorge1313]

What mpgs are you guys getting with in your 6.2 engine city and highway . Let’s compare and see what the norm or average.

My 07 Denali XL with the 6.2L, after the installed mods, gets 11-12 mpg in the city with a reasonable foot to the gas pedal (10-11 mpg with a more aggressive foot to the gas pedal), and 15-16 mpg on the highway. I use 93 octane gasoline.

I think there's already a thread like this with almost the exact same title...

Go get a hybrid 6.0L getting fantastic numbers.. on my last highway trip it was 45 MPG on the 6.0L driving @ 55-60mph.... I MADE the electric do all the work. while it was idling in v4 mode most of the time That E-Assist can really boost the numbers quite a bit since figuring out how to "manipulate the e-assist."..
158 Miles only required 3.5 gallons of fuel Yes I pumped the gas COLD (40°F outside)... so the fuel vapors condensed..

number break down
0.558 gallon on the down hill side
2.944 gallon on the uphill side it's expecting as the engine will do more work to overcome the hill so more fuel is going from pretty much sea level to 4,000 ft then to 2200 ft

I mean if you hate the MPG go get a Prius or Volt or hykon/hyhoe/hycalade

Who drives 55-60 on the interstate? I can’t do it unless the weather is crappy. I’m at least speed limit plus 8.

well on packed freeways you will not be going more then 4 or 5 MPH (that is a joke around here at lest on the I-405)

traffic is getting worse here in LA normally the FREE flowing freeway on the weekends is no more...

yeah that used to be a thing... no traffic weekends

between 12 and 3:59am is when there is no traffic now every other hour is rush hour from 4am to 11:59pm...

that gap will probably close soon as things change.... overtime
when there is 24 hour rush hour...

might as well take advantage
and hypermile or ultra-mile it..

anyways every time I save money on gas it will turn into profit ..


I all ready have $190 I saved on gas.. since I had it. that will go towards maintenance.. or even a brand new replacement battery..... for every 10 miles I save a dollar on operating costs




in the city the traffic lights are Highly predictable better then getting stuck at each light anyways

Ouch. That’s bad. Come east friend, we aren’t that bad yet.

To be honest, I could not care less about the gas mileage on my truck. It is my second, or fun vehicle, and I admit that this is a huge difference in how I view gas mileage. If I want to save gas or money, I'll just leave my truck at home, and fire up my Honda Fit.

If the road is open in front of me, then I drive like there is no tomorrow. I am courteous, respectful, and cautious of other folks on the road and their safety (no weaving across lines or gross tailgating or headlight flashing), but otherwise, it is just me and my truck against the road.

I bought and modified this truck to be loud and fast (not nearly as fast as other folks and their mods on this Forum, of course) and purely for my fun, reminding me of the glory days of muscle cars and the sounds of revving motors and burning tire rubber. Reliving my childhood? Absolutely (though not quite so stupid)!!

Just my 2 cents worth.....

Hey Brent, have you run E30 or any Flex Fuel through it yet? Surprised myself and calculated that running E85 has saved us over $400 for the last 5,000 miles.
