I'm not sure if this has been talked about on here but why does the 2015 hd's have the old 6.0 engine in them ? with all the technology out there they could not improve on this engine to .

1. get better gas millage.

2. get more power and torque .

 

because it seams to be able to tow close to the duramax as far as weight goes .

 

I say this not that i tow everyday but i do tow but not enough to justify another $9K on a diesel .

 

after seeing those people who do that run in Colorado on u-tube it looked like the truck could not get out of its on way towing to it's limit the brakes stayed cool as they pointed out on one side of the run. here is the video

.

 

I'm hoping it will do the job but that video just killed it for me

Cheaper to maintain especially for fleets. 6 quarts of oil (versus 8 quarts for 5.3 and 6.2) and cheaper oil (5w30 vs 0w20). Cheaper for GM too probably as that motor has probably bought and paid for itself by now. Also, no iron block Gen V. 6.0 is iron block.

 

I love mine. I've had 3 of them, two older ones (2004 and 2006) and now my 2015 and the newest version is a great engine.

 

Also, as far as the gauntlet video you posted, if I recall, the 6.0 pulled the gauntlet faster than the new 6.4 Hemi in the Ram in their other test.

 

And honestly, most people who will tow like that would jump for the diesel in the first place. Gas trucks can do it but the diesels will do it better.

Yes, the current 6.0 is a great motor.....but I would still love to see GM give it direct injection (to get a similar boost in power and mpg, like the new 5.3 and 6.2)....or just upgrade to an iron block 6.2. Even if they tuned it down a bit from the 6.2 in the 1500 trucks, 390-400 hp and 425-440 torque would be plenty, especially with an 8-speed and 4:10 gears. :thumbs:

I would love to see it with torque in the 400-500's if you could get that much out of a gas motor .

 

The 8.1 did that and the 454 was right around 400. The Ford 3V V10 was up there too. Big gas engines were never that popular with the masses. The nice thing about the big blocks was that they had lots of torque low in the power band. With turbo charging it should be easily achieved, but I don't think the big three are going to be too quick to produce another gas option that doesn't have the appeal of diesel or the not-so-terrible fuel economy of a 6ish liter V8.

 

i like the Ike Gauntlet test, but sometimes they borderline on the ridiculous. It's impressive that the Chevy didn't overheat the engine or transmission. Same for the test they did with the 6.2 F250 that basically went up the mountain screaming in 2nd gear.

I'm thinking the 6.0 is on its way out within the next few years and is going to be replaced. With what? Who knows. 6.2? Possibly. Something else? More likely. GM has to continue improving fuel economy to meet the CAFE standards.

The 6.0 HP/TQ numbers don't compare with the DMAX HP/TQ numbers but in fairness did you watch the GMC/Chevy equipped with DMAX run the Gauntlet? Yes the DMAX does tow better but none of the video's of the DMAX towed as much weight and there times where no THAT much better. I'm sure most of us don't ever tow to capacity and on hills like that. I LOVE the 6.0 (my 2nd GM w/ 6.0) and just could not justify the extra 8K++ for a DMAX and the extra maintenance cost. Like 'The Rod' said, I'd love to see DI added to the 6.0 too.

Year for year the 6.0l might not tow as well as the same year DMax, but I can tell you my 2012 tows every bit as good as my first (1989) and second generation (1995, 1999, and 1999) Cummins. Only with the introduction of the electronic 3rd generation (in all makes) did the big gassers start losing the towing wars.

 

It amazes me what I did with an anemic 318 or 360 Dodge back in the day, they were less than 200hp/300tq. Have the trailers gotten that much heavier?

In the few years I owned my 2008 Dmax- The maintenance side of the fence wasn't too aweful. It's just the cost of Diesel that can suck sometimes. GM really did a great job with the Duramax and chassis and with the Allison, they had the winning combination for many many years until Ford figured it out with the current 6.7L And I have nothing but praise and respect for Cummins as well. It's just too bad it is in a Dodge. But even Dodge has improved. Not to the point where I would trust them again, but maybe in a few more years. But my next truck is defenitly going to be a Duramax again.

Tow my 9500# Travel Trailer with my 2015 2500 6.0. Sure, it doesn't tow like a diesel does, but since I'm not towing everyday not worth the extra money. I've towed a lot of different trailers with different trucks, and this one handles it with ease.

Well, in all fairness, if you shoved air into the 6.0 like it gets shoved into the Dmax, the numbers would be impressive. The Dmax without a turbo would be one of the old N/A diesels of the 1980's. I would be willing to bet that a turbo or blower on a 6.0L would be the difference between night and day. Not really a contest when one engine is gasping for air and the other is getting 30lb of boost shoved down it's wind pipe.

Like I said, the 6.0 still wiped the floor with the Ram gasser. People want all this "new" tech, turns out some of it has drawbacks, and the "old" stuff still works....

Yeah, kinda like old rifle cartridges compared to the newer stuff. I am still fond of a 30.06 or a 45-70, or even the old 30-30. Say what you want, but not a lot walks away after getting hit with a 405 grain bullet from a 45-70. Some things that have a history and have proven themselves are just worth keeping around. That is why I am seriously in talks with getting a 2015 2500HD now. Yeah, they might do the 6.2L next year, but that thing is so full of stuff that can go wrong. Scotty said it right on one of the Star Trek movies... "the more complicated you make the plumbing, the easier it is to stop up the drain".

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
