Chevy 2500HD Extreme MPG Towing Test With 6.0L Gas Engine! 

What about the 6.2

​@@300goincray3 not really, they suffer from having d.o.d/afm just like the 5.3. 6.2 fords are good though.

The 6.0 in the 2500 doesn't have afm

I just bought one but my ecoboost pulls my trailer better which made me kind of sad 😂

Yeah the only reason I would go to a diesel which I might in the future is if I decided to start pulling 2 cars long distance! Otherwise I really enjoy the gas truck. Thanks for watching glad you enjoyed the video.🤘

That’s kinda what I’ve seen as well! I’ve had my 24 enclosed behind the truck and with some head wind I’ve seen 8-8.5 which is definitely heavier and only seen about 1 mpg difference. Not the greatest but it gets the job done!

That’s pretty decent! 60-65 seems to be the sweet spot for mileage but 80 gets you there a lot faster 😂

Yeah that's the only down side. Gotta stay in the slow lane on the interstate lol

@@BuildTuneRace did you tune the ECM for better mpg?

Bro let’s me know what you have done I want those number I literally have the same exact truck

Great info. Not to mention the extra cost of diesel, I’m with you, they seem more expensive in every way.

Nice I definitely think the change from 60-75mph makes a big difference in mpg

What do you tow by the way?

My 01 6.0 has 233k and gets 15+ mpg. Solid and reliable

@@aludtke86 must live where it's flat?

@@aludtke86 Is your truck a 4x4? 15mpg...must be unloaded and on the hwy.

@@Elongo82 I live in Northern California Humboldt county. Do lots of firewood cutting. Doesn't seem to change my mileage whether it's fully loaded with madrone or empty

@@SudburySaturdayNight1787 2wd

12,000 lb gvwr ? Im wondering how much and what i need to upgrade on my 6.0l ls to allow it to pull a 14,000 fifth wheel with ease.

Also, which fifth wheel do you have? Ive been watching rv videos and want to see if theres lighter weight ones that i like

I'm using an RBW Lil Rocker rated at 16K. I've been using it for almost 20 years. It's not too heavy, so it's relatively to remove .

For a 6.0 LS to pull 14,000, I would do it in stock form. I'm guessing you have 4.10 axle gearing. If so to make that engine pull a heavy load easier, I would recommend upgrading the air intake and exhaust. Change the axle gearing to 4.56 or 4.88 if you run in hilly terrain. You rpm will be higher but a 6.0 can run at 4000rpm all day long for years without issue, as long as it is already in good shape. Wind resistance is a big factor. These things will help it tow better but with ease is a relative term. With a 14K trailer watch that you are not exceeding your payload as that will most likely affect handling and safety. Some people will say a 14K trailer will affect safety. The truck itself can handle it. The 8.1 and the Duramax had higher capacities. Also be mindful of engine and especially transmission cooling.

@@garydoebler1263 im not sure how that works, im still learning truck stuff. I heard 4.10 axle ratio is good for towing. I only plan to tow about 4 to 6 times a year and my truck is also my main transportation thats why i didnt get a diesel so i might be good just upgrading the motor to a stage 2 maybe 1. Im gonna have to talk with a specialist about this but im also still confused about how much fifth wheel i can tow. On my tech specs it says max 15,500 but on google it says 12,000.. on my tech specs it also says for a travel trailer the max is 12,000.. any idea?

Definitely a solid truck all the way around! That’s a lot of weight for sure!

@@BuildTuneRace yeah when I do tow that heavy it's only for around 10 to 20 miles down the highway I don't want to stress the transmission to hard

Definitely don’t want to mess up the trans

Heck yes! Your the guy I met right?

Yeah I'm the guy. I needed gas at the right time was able to see the truck in person! Awesome build!!!

It was nice to meet you man glad you said hello. Hope all is going well!

Hey same here. Always good to meet good people making it happen. Hope to get more tires scratching the road near you!!👍

Yeah same I've noticed unloaded I get 11-13 and loaded it's about the same maybe I little bit worse like 10 but these trucks hardly notice when you put wait on them I love my 2016 double cab long bed thing is perfect for what I need it for didn't need the full crew cab but needed the 8ft bed for towing my gooseneck. I also had a 2015 1500 crew cab 6.6ft bed it was a nice truck but definitely not comparable to a heavy duty like my 2016

I had a older Duramax that started to have a couple issues and ended up getting this truck. Only way I’ll own a diesel again is if it has a warranty lol but really enjoy this truck!

@@BuildTuneRace i have a 2006 Duramax with over 300,000 miles without ANY MAJOR SERVICE, a gas engine is NOT DESIGNED to be a daily tow vehicle

You are WRONG a diesel gets 15mpg at the least, 5 miles per gal LESS isn't even in the ballpark

Merry Christmas! Thanks for supporting the channel! Definitely should get a cover for traveling lol! Can’t wait to do even more in 2021!

Really would like to know how one of these trucks would do with a supercharger towing!

Love to see a video of it towing when you do.

I have a 2011 Silverado 2500HD 4x4 6.0 I'm researching doing the very thing you are. But, I'm looking at the Elderbrock EFORCE supercharger over a Procharger.

​@@timphilmon8573did you upgrade it? Im looking to upgrade my 04 because i want to tow a 14,000 lb fifth wheel

​@WalkingDead520 have not yet.

😂I was about to Google that rt now. I have an 09 silverado Hybrid

Definitely made the ride worth it! Are you going under water in those tunnels? Pretty wild!

@@BuildTuneRace about 50 '

@@jeffpennington2043 dang that’s pretty crazy!

Democrats, people keep voting for them and then wonder why the economy is in the crapper. NO FIX FOR STUPID!

Yeah once they put a dpf system on that get shit mileage...2016 f250 diesel 4dr regular box 4wd 3:73 @68 mph pulling a 38ft 11,700 pd 5th wheel camper best we got was 11mpg n that's with a tail wind no hills

That’s not too bad the 6.2 in the 1500 do pretty dang good! Mine with the 24ft enclosed I have behind it gets around 8 so pretty close to the same mileage as the 1500’s The New DI engine are definitely a bit more efficient!

GM recommends only activating the tow/haul mode if at 70% or more of the towing capacity. That little S10 on a trailer is only about 40% towing capacity.

You got one of the best years of the 6.0 vortec man. I believe its the 2ng gen chevys from 07 to 2013. They have the best 6.0 engines. Super reliable. Take care of her and she'll last forever. I have a 2004 which is still better than the 3rd and 4th gen chevys.

@@WalkingDead520 it’s the same engine 07-19.

My 2016 ram 1500 3.6 v6 averages 13.5 pulling nothing neither lol don't feel bad bro, at least you have a V8 lol

That’s exactly how it goes lol

Does it has heavy stuff on back of truck?

Warranty is up in another 14k miles lol

Maybe a modern one. My ‘04 5.3 would’ve gotten similar or worse towing his trailer, especially with my larger tires. IMO I think he’s right at the cutoff of when a half ton would begin to suffer mpg-wise vs a 2500.

My 2004s first gear ratio is 5.79 max, 2nd gear 3.31, 3rd 2.10, 4th 1.31, 5th 1.00, and 6th .76

Around 15-16 on the highway

😂 it’s definitely no Prius lol

In the 2500 they went to the new 6.6, more efficient makes more power and maybe a small amount better fuel mileage. In the 1500 they went to a new aluminum 6.2 direct injected engine (l86) I believe. Which makes good power and gets a little better fuel mileage

@@BuildTuneRace Thanks for the info.

2017

Bullsh!t! You're obviously NOT driving a 2500 3/4 Ton pickup

That’s right I’m not. An ecodiesel is a ram 1500

Problem with a 1500 ram economy diesel you are limited to probably a 8000 pound tow difference on a 2500 series truck, so I bet if you add that weight and tried to pull the max weight a 2500 can pull you would not be getting that mpg. I have a 2017 3500 LTZ dually 6.0 vortec and average driving around town unloaded mpg is lowest roughly 11.7 mpg highest 13.4 mpg, towing I get around lowest 7.8mpg highest 9.6mpg towing around 25k

I traded my 2016 dmax in and honestly I thought it would be a bad deal, but he'll I pulled my enclosed trailer around constantly and the damn thing stayed in regen so I average 10mpg the best I ever got open highway was 17mpg. So not a huge difference from the 6.0 vortec. And the 6.0 vortec is cheap and easy to work on.

@@damionjones8944 you could be right but like they say get the right tool for the job. I just pull a corvette on a trailer and my ski boat
