That should say 5.3 liter.....what is your mpg?

If you have one of these, what kind of real mpg do you get? (solo and towing)
Post the year of your truck too.

I'm thinking of downsizing from my '07 Yukon Denali to a 'burban with the smaller engine.

I have a 2004 Yukon XL 3/4 ton, 8.1L engine. Get about 12 mpg around town and highway, about 8 mpg when towing.

My old 02' Tahoe with the 5.3L got around 15/16 in town and I think I hit 20 mpg once on the highway driving back from Wyoming (75-80 mph).

2004 Yukon XL. Wifes truck. We get the same as shamrock for highway and around town. We don't tow with it so I can't comment about that.
Haven't had any problems with it except for I had to change out the power steering pump with hoses last year. Then this year the diff bearings had to be done.

I have the same 5.3 engine in my 07 Avalanche, which I would guess is the same as the Suburban less some steel. My guess is the MPG is similar to LaRue and the computer says an average mpg of 14.2, but I don't check since I bought it to haul my boat and it is what it is... :D:D I wouldn't go to anything less to haul it. The 5.3 does great!! For me and my boat..

I have a 2001 Yukon, I get 18-20 highway but I do drive the speed limit. 12-15 around town depending on the season more in the summer as I'm in 4 wheel drive 90% of the time in the winter, and again 12-15 while towing depending on the terrain.

I have owned both and would recommend sticking with the 6.2L in your Denali. I liked the 6.2L much better and saw a good 3-4 MPG better with the 6.2. The towing/performance/power was way better as well. It was a win-win for me upgrading to the Yukon XL Denali over the 5.3L Burb. I have thought about getting another Burb but I can't, I want another Yukon XL Denali or Escalade ESV so I can get the 6.2L.
I think you will be much happier sticking with your Denali. My :twocents:

'09 Colorado 5.3 and I love it--runs like cars of old but I know it is lighter than Tahoe or Suburbans. Pulls my 190 but it can feel light in certain cases but if I had trailer brakes it would be fine. Highway mpg best just over 23 pulling boat 16 and will go faster than I want to pull a boat.

Man, I wish I got that kind of gas mileage. I have a 2003 3/4 4x4 suburban, 6liter. I get right around 12 mpg, bought it new. It's a great vehicle though. My 2004 3/4 4x4 siverado gets about 13mpg. I go about 75 on the highway. No towing as I have a lift. I knew the 5.3's got better mileage but I didn't know that much. Tell me more about that colorado!!

Heard similar to this from a friend of mine. He has an 07' Escalade suburban with the 6.2 and the "more than 4 speed" tranny. He indicated on a ski trip last year through winding roads his mileage was around 18-20 mpg. He has been very impressed with the vehicle and the gas mileage as well. I think it's a 6 speed tranny which helps quite a bit.

He also tows his 30' travel trailer in the mountains of Colorado. Said it pulled better than his older V10 Excursion. A definite Ford guy turned Cadillac guy (his words)!

Best my 6.2 ever did was 17-ish highway on flat roads. No way that truck will get 20 mpg.
I get 9.5-10 mpg pulling the boat, mostly highway to the river here.
I'm also thinking suburban so I can put a plow on it for my driveway (2000 ft long). My last 2500 suburban was a plowing machine, guess I should have kept it. The Denali is too nice for plowing (plus there is no 4WD switch so it's on demand AWD, not the normal 4WD)

Thanks to all for your input/opinions.

Good point. I didn't realize there was no transfer case switch.....or even a 4wd option.

The front diffs. On chevy's are prone to failure (at least what I've read on chevy forums). They say not to wait to change the gear oil and go synthetic up front. It already calls for it in the rear but not front. Guys have said that 10,000 miles after changing gear oil it was black again. Synthetic stayed much cleaner. I've had good luck with both my trucks. I changed front rear and transfer case oil more than regularly and had no problems. My buddies Denali had a front diff failure, it would go out of gear when accelerating thru a intersection (not good). He also had allwheel drive. Their is also a very simple procedure to change all your trans fluid by taking off trans cooler line, put a hose over the opening of the cooler and start engine. It pumps out about 4 qts. Shut motor off, Refill trans and repeat 3 times. I get dirtier changing my engine oil than by doing this. Both vehicles have well over 100k now and run like new.

I have a 08 Sierra 5.3 2wd with the 4 speed and 3.73 gears, on the highway it will get 18-19 at 70 and mid twenties when the 4cyl mode engages. I pulled a loaded 6x12 UHaul and averaged around 15-16 on the interstate. I got 16 pulling my S S from Ft Campbell to Mobile with everything that would fit in the truck and boat

Yup - Denali's won't be great plowing machines with the mounting of the plow and AWD. Sounds like you need a 3/4 ton crew cab Duramax. :) Throw a canopy on it and you have your Burb with a Duramax and only lacking the third row seating.
Or throw some big bucks on a DuraBurb outta of Florida. It's just money......

Looking for a little help here guys. Wife and I are looking at a 2011 Yukon XL with the 5.3. Going to look at the truck tonight, but the dealer claims the towing capacity is only 5k lbs. Wondering what the K5L towing package includes and also wondering if anyone on the board is towing their boat with a Yukon/Suburban without the K5L towing package?

Right now I'm towing the 92 PS190 with a V8 4Runner and it's not a problem, but I'd sure like to be able to tow it with the Yukon without any issues as well.

Ski-me
02-29-2012, 02:12 PM
I don't know the capacity of the 4runner and the Yukon XL seems low but even if both said 5k towing, you get the longer wheelbase and heavier vehicle. It will tow your 190 much better than the 4runner for sure.

Although hugely different, I tried towing my 205 with a lifted K5 blazer that does teater-totter quite a bit. Pulling with my Yukon XL is just amazingly better. That wheelbase is a great plus for towing!

Here it is according to GM Autobook for a 2010:

Axle:
GU4 - REAR AXLE, 3.08 RATIO [Not available with [K5L] Heavy-Duty Trailering package]
GU6 - REAR AXLE, 3.42 RATIO [Included and only available with [K5L] Heavy-Duty Trailering package]

K5L - TRAILERING PACKAGE, HEAVY-DUTY includes [KNP] external transmission oil cooler and [KC4] engine oil cooler, provides increased trailering capabilities [Includes GU6] 3.42 rear axle ratio]

Max Trailer Wt.
3.08 axle
5000lbs. Dead Weight Hitch
5200lbs. Weight Distributing Hitch

K5L (w/3.42 axle)
5000lbs. Dead Weight Hitch
7,778lbs. Weight Distributing Hitch

2007 Silverado 1500 with the 5.3. Tows my 2010 X-15 and horse trailer with ease. I have 101,000+ miles and it shows overall MPG at 15.3, so I don't distiguish where or when, just average. Love it. Very comfortable to drive.

The towing capacity on the 4Runner is 6900 lbs. The towing capacity on the Yukon I'm trying to figure out. The dealership is saying 5K lbs, but everything on the web says with the 3.42 axle in the XL 1500 4WD the towing capacity is 7900 lbs. I'm going to get the VIN tonight and stop by the service guy at the dealership and see if he can pull me the specs on this vehicle so that I can get some comfort in what equipment this truck really has. I'm not going to go by a sales guy or the fact that it has a hitch and some wiring.

I'm with you guys I think the Yukon XL should be a great towing vehicle, just concerned that they're saying 5k lbs towing capacity with the extra weight/length of an XL I don't want to run into any issues.

Thanks

That isn't right. I pull a tandem trailer in the fall for a business with 7k to 8k of pumpkins with my Suburban all the time.

Youre close- the V8 4Runner has a towing capacity of 7,000 (4wd) or 7,200 (2wd). Very capable for a mid-size SUV (I love mine).

Ive driven a newer 'Burb with the 5.3L and 6sp tranny, and was impressed. Its no powerhouse, but the tranny really helps it get out of its own way. Not sure it will pull stronger than the V8 'Runner, but the longer wheelbase and heavier weight will make it a good tow vehicle. Even if the limit is a legit 5k lbs, that far exceeds the weight of your 190, so you'll be just fine. Id be willing to bet that the difference between a 5k and a higher rating would be something relatively simple- like the hitch type, or an additional transmission cooler. Doubtful it has anything to do with the base vehicle itself.

It could very well be right.

According to the 2012 Chevy Trucks Trailering Guide, a 1/2 ton 4wd Suburban with the 3.08 rear end has a towing capacity of 5,000 lbs.

I stand corrected on my assumption above! The rear end makes all the difference... the 3.42 rear end is good for 8,200 with the optional heavy duty trailering package.

I think you're more than fine towing your size boat with that Yukon XL. I'm going to tow my '05 X-star with my '07 Suburban 5.3.

If you're not in a hurry, I hear GM is changing the Yukon/Suburban in 2013. I'm waiting to hear more about the next generation Suburban.

Wishful thinking, but they did a prototype 4.6 liter diesel a few years back. Rumor was it might get 30 mpg highway. I'd settle for a turbocharged 5.3 liter to spank those Ford Eco-boost trucks! :D

I am not holding my breath but the latest diesel publications are spinning up the rumors again that a diesel in 1/2 tons is back on the table. GM insiders are saying they are seriously considering a smaller diesel for their 1/2 ton trucks and they are having discussions with Cummins regarding their 5.0L V8 diesel instead of the 4.5L Duramax which is confusing. The rumor is Cummins may have found a way to lower the cost of the motor and the emission equipment to be cost effective enough for people to consider the diesel over gas. A few years back just the emission equipment on the Cummins when Dodge was considering it in their 1/2 tons was more expensive than the entire 5.7L Hemi drivetrain. That would have made it way too expensive to consider over a gas motor. Ram is looking into using VM Motri diesel since Fiat just purchased a 50% stake in the company and Ford is not considering a diesel in their 1/2 tons unless the other two go to market first. But Ford also just dumped a ton into the V6 ecoboost so a small diesel might not make sense.

Either way it would be nice to see GM offer a diesel in the pickups and Burbs.
