Our GL450 avg 13 with similar driving condition. It uses premium gas, so pretty much a wash.

WHY CANT THEY MAKE THE ESCALADE DIESEL ? ALmost all SUV in Europe are diesel, and they run fine & good gas mileage

There was a Diesel planned for 2010, but they cancelled it to fund things like the Volt. It would have achieved 30MPG EPA highway in an AWD ESV.

I don't know why people constantly bash the Volt (yes I own a 2013 Volt along with an 07 escalade). I'd bet developing the volt has nothing to do with it.

Given the fact that diesels exists all through GMs full size truck line- I'm pretty sure the cost of fitting an escalade would be next to nothing. On fact there are after market companies that do this right now. I'd bet it's a marketing issue more than anything else.

Truth is - the American market still I doesn't like diesel. When companies like Audi and MB have trouble selling diesels in their SUV (Q7 and GL)- which easily score 30 mpg- then GM would be hard pressed.

Put me on the list for diesel escalade too- having had GM diesel trucks- I can't imagine why they don't do it. Power, economy, low maintenance- it's a no brainer.

BTW- don't be surprised to see the Volt technology in many more GM products soon- perhaps implemented differently than the extended range drivetrain. The upcoming Cadillac ELR is basically a Volt. It's killer tech, and when/if it grabs hold - GM will have a winner on its hands.

I have a 2007 EXT AWD with 125K miles on it running 87 octane gas.

Just got back from the beach and on the trip down there (about a 3 hour drive - 150 or so miles) I got 18.4 mpg doing mainly around 60-65 mph. I got about the same coming back home.

Usually during a normal week I get around 17 mpg or so I guess. I've never gotten like 14 mpg though...that's ridiculous. Even if I just drive in the city only on short trips all the time I get 16mpg.

Nope, has to do with using non ethanol gas. Ethanol kills mileage. I just drove 288 miles mostly highway this past weekend and got 20.2mpg doing 77mph. Stock w/22".

I expect I'll get better once I get a tuner, headers, and bypass cats. No emission testing where I'm moving. I am not a light foot and I don't use cruise on hilly drives, my mpg drops 1.5-2mpg using cruise. Use cruise only on flat straights.

Using remote start kills mileage too, but worth it :)

9.3mpg average after taking lots of highway trips a couple weeks ago. but usually its around 4.8-6.2 though. I remote start it always, and most of my driving trips are 2 miles away but take 30 mins to go those 2 miles due to traffic and 18,000 lights and stop signs. My friends usually joke around and ask me how many gpm I get.... instead of mpg ;) My last fill up was $115 too as gas here is expensive. But it doesn't really bother me, I bought the car full well knowing this, I wasn't bamboozled into thinking I was going to get stellar gas mileage. If you can afford this car than you can afford the gas for it, and if not you shouldn't have gotten in in the first place.
I bought it because its big and powerful if I cared about gas mileage I would've gotten a prius.

These kinds of threads always make me lqtm ... there's always miracle workers who get better mileage than the already exaggerated manufacturer specs. Apparently some of you drive 110% of your time without passengers or cargo on a highway at 45mph downhill with a stiff breeze at your back. I mean honestly, I once drove my truck through Florida highway flatland on a full tank at 70mph on cruise control and barely got 17.5mpg. Heck, my Tahoe Hybrid got worse mileage in real life conditions than some of you are declaring on your ESVs. http://i930.photobucket.com/albums/ad149/Deafbhoy2/eyeroll.gif

No modifications whatsoever, except 0W30 Mobil 1 oil and Mobil 1 75W90 in the diffs. No BS, just a well-maintained, perfectly broken-in L92 with tires inflated to 38psi, and gently accelerating.

ok, here is my latest. We live in daytona. We went to Key West last week and I got these numbers.

17.1mpg down to Miami. 75mph or so. We had bad weather, heavy rain and such. Filled up in Miami and on to Key West. Reset DIC with AC on and passengers. Made it to KW and back to Ft Pierce to refuel. 23gals, got 430+ miles. I was watching the DIC and it said 18.7mpg. I did the math, it was 18.7mpg. Now the trick was the Keys stretch is a 55mph and under zone. You can run 65mph here and there but it's almost 300 miles down and back that stretch. No cruise control. Cruise will ruin your MPG. Coming up to overpasses at 75-80mph, it'll drop two gears to hold speed if the grade is steep, which isn't much in flat Fl.

See? it IS possible to get 20+MPG on the highway with these things, you just have to drive carefully. Make sure the tires are at 37-40psi cold, use good 92+ octane fuel (Costco works great), and don't go berserk stomping the throttle passing every car in sight. If you try to keep RPM at 2000 or below when accelerating, you will be amazed at the fuel economy you can achieve. I have trouble believing the mileage I'm getting, but I hand-calculated it and it's real. I can see how people who are frustrated at their poor mileage can have trouble believing what is possible, but having driven mine for the past 108,000 miles, I found what works and what doesn't. I used to have trouble achieving 18 on the highway, but the last two 1000+ mile round trips to the cottage have yielded 21.6 and 21.3. That's pushing the average fuel economy reset button at the start of the trip, going on the trip, then looking at the display when I pull back into the driveway.

One neat range-improving thing I learned in all of those miles: The fuel tank will take an additional 1.5 gallons after the pump clicks off the first time. If you can slowly flow the fuel in after the first click (some pumps won't do this, and some states have that vapor collector thing that prevents topping up), you can fill it all the way up to the top of the neck to improve your range. My miles to empty display shows 600+ after refilling when I do this.

I have gotten 20.5-ish out of mine on a 400 mile trip. I wouldn't say these results are typical because I do pride myself on being able to squeeze everything I can out of a gallon of gas. I would like to get a little more out of it once it gets some miles on it. Another member was getting something like 24+ out if his, this was with extensive tuning though. Not sure he had as much fun driving it as the rest of us do.

On a side note, in a couple of weeks I'm driving 1000 miles flat ground from DC to Miami on a straight highway shot at night with no traffic ... I'll set the DIC at the start and see what it shows at the end. At 70/75mph I'll be happy if I get 17/18 mpg.

06-09-13, 08:15 PM
17-18mpg is a realistic number with cruise control engaged, although 75mph is kind of fast while trying to get decent mileage. To get good mileage, don't use cruise. You sacrifice a lot by accelerating up hills to maintain speed.

soulsea
06-09-13, 08:47 PM
I don't think there is much of an elevation change tween DC and Miami, it's mostly through low country and Florida ... in that setting it might actually consume more gas trying to sustain an average speed footually (I don't know what the foot version of manually is) than to use cruise.

Once ur vehicle is up to speed, to maximize ur mpg u gotta do some coasting, which requires u to take ur foot OFF the gas for short distances

Any low double digit mpgs is almost always attributed to a constant steady or heavy application to the gas

Y'all's new Escalades should easily out perform my 98 Deville IF your driving habits don't adversely affect it

City driving is the ONLY time u should see low double digit mpg

If ur seeing it on the highway at cruising speeds than u may have a heavy foot

As always, fuel mileage depends on the driver, the vehicle, the driving conditions and locations, and the way the driver operates the vehicle.

I don't own a "Cadillac" variant of a GMC or Suburban truck and probably never will - but the rest of the 20-odd vehicles I've owned have had gas mileage splattered all over the map - from <10 mpg to way over 30.

My current 3 - the STS and 2 F-150's - vary widely: The STS goes from a low of ~14 in slow city driving to 25.2 on long Florida runs. Depending on load and road type, the F-150's vary from 11 or so to a max of 18.3 (they're both 4WD 4.6L trucks). Both types use Shell 87, and the STS gets Shell 93 when doing crazy Caroline County road runs or at the Cecil County Dragway.

As in all vehicles with onboard fuel computers, the short-term and long-term figures vary widely, are constantly dynamic, and take longer to settle out on highway trips if you don't reset the totals at fillup and instead simply let the system continuously calculate its own figures. If you learn how to use that little calculator in your cell phone you can always use the time-honored instant gratification fallback at fillup: Miles traveled / gallons used = gas mileage (for that tank).

"My gas mileage is better than your gas mileage" is a moving target argument - there is NO real answer................. and, if someone wants to start an argument they had better be ready for counter-arguments and spicy language - no reason for name-calling or administrative action unless the argument/thread goes into the sewer. Then posts and people begin to disappear. :sneaky:

DARN!!!, I missed the name calling...

I use my instant trip and gallons used features to gauge my "driving performance"

Occasionally on a one way trip ill reset both those features and the Avg MPG and Note the End Results for that trip

U can't really take a road trip and calculate your performance on that trip if the computer is using yesterday's calculations combined with today's ... or last weeks

My avg everyday trip to work (city/hwy) and back home is usually between 14&17mpg... Thanks to a gentlemen (Sub) who advised me to replace a faulty FPR that was causing poor 12mpg daily driving performances

Completely concur on the driving habits of the operator tho... U can't expect good double digit MPGS if you're constantly flooring the gas and racing to every red light, which I ALWAYS see other drivers doing...

Ur likely never gonna see double digits if ur driving like u own a hot rod tho

Y'all's new Escalades should easily out perform my 98 Deville IF your driving habits don't adversely affect it

^^^ Totally false. Our cars and engines are as comparable to their Escalades and engines as apples are to pumpkins.

If your base Deville does not easily get over 25 mpg long-term highway you have problems.......... It is not uncommon for a Deville or DHS (NOT a new "DTS") to get 28 mpg on 87 octane on a NY - Florida run - with 2 people and luggage aboard

I don't think there is much of an elevation change tween DC and Miami, it's mostly through low country and Florida

You ALWAYS get much better gas mileage going from DC to Miami: It's downhill all the way. It's coming back uphill that's the killer .......... :devil:

(Where in DC are you ?? I'm a 5th generation Washingtonian - born in the OLD Georgetown Hospital) Karen and I do a Gainesville run twice a year - her younger daughter lives there. The STS gets just under 25 on those hauls.

Driving style obviously is the main variable among many deciding what one's average MPG will be, as well as terrain, ac usage, gas grade, altitude, temperature, traffic, etc etc. HOWEVER that being said, even with every variable optimized, there is a cap to what the maximum mpg average any vehicle can get determined by its engine size, engine configuration (how it's aspirated, injected, etc), sprung/unsprung weight, rolling resistance, aerodynamics, efficiency of the engine and its drivetrain components (2WD/4WD/AWD).

So yes, in real world conditions there's a way to optimize mpg performance, but only up to a certain point. I mean I could reset my DIC at the top of the mountain and it'll read 99mpg at the bottom because I'll never press the accelerator, but obviously that's no way to accurately measure fuel consumption.

The figures Tec80 claims are a physical impossibility on a stock ESV over any meaningful length of terrain, heck they're beyond the reach of a 5.3 suburban driven by nuns ... believe me if there was the slightest merit to them GM would be more than happy to advertise better mpg numbers, but obviously they cannot duplicate anything near them. In fact Tec80s figures from his ESV are better than those of a Tahoe/Esky Hybrid.

It's just internet nonsense.

I jus find it hard to believe that with all the Advancements in fuel consumption tech that newer model (Any Cadillac) will perform worse than a 15 year old northstar engine

That would lead me to assume GM has declined in fuel tech development, not improved

I have no expertise but I've been in Escalades with 18/19avgmpg on the dash... I may be presuming to much with such a general statement as those numbers may be from a long trip, I don't know either way

Not trying to debate on an issue I have no expertise in but for me it jus kinda defies logic that GM made no advancements in fuel consumption in 15 years

Also, I haven't had an opportunity to drive long term hwy since I changed the FPR. I can certainly imagine it will make 25mpg or better since I'm easily hint 19/20mpg on short hwy runs

Used to date a girl who lived just off Foxhall, west of you. A daughter went to AU, Dad ran a hardware store on Wisconsin just downhill (northbound) from Tenley Circle. An aunt, dad's older sister, lived at 5050 Loughboro Rd. NW.

There is a WORLD of difference between hauling around an Escalade and a Deville/Seville !

Yes
The Escalade weighs in at 7200lbs

My Deville weighs in at 4500lbs

I will concede to your point on that

What type of gas do you guys use?

Left DC at 7am got to Aventura at 9pm, 1050 miles in exactly 14hrs, which averages to exactly 75mph. I did stop for gas a couple of times and for a burger, and the cruise was set at 77/78mph.

DIC shows exactly 18.4 average mpg, which is about 1mph better than I expected. I guess if I rolled at 65mph without cruise and AC and had a 2wd, 20mpg is possible ... but that's about it on a stock esky on 93 octane.

Tired now ...

2008 ESV, 55K with stock 22's. NYC to DC, 18.8 mpg - light traffic most of the way. Return trip 16.2 mpg. Not as lucky with the traffic.

I live in Atlanta and my Ext averages 9.6 mpg using super premium gasoline. I wish there was a way to improve the mpg. It rides on 24's so that might be a big reason for the low mpg.
