I have the 2024 GMC 2500HD 6.6 gas. Did first oil and filter (Mobil 1 Advanced Synthetic 5W30 w/Delco PF 63 filter/Delco drain plug gasket) myself at 1033 miles. Now I will do it at around 4 to 5k. Will occasionally haul a Lance 825 camper and pull a Northriver 18'6" aluminum boat for a few trips a year, so not doing real heavy hauling. So far love the truck...
@@slmjake I haven't done a trip yet. I installed the Torquelift frame mounted camper mounts and wired the new Lance camper pig tail so will be testing soon. I didn't want to haul or tow until I got 1k and oil changed. Is ready now but not fishing yet...
I’m going to have to go drive a 2500 with the 6.6 gas motor & the 10 speed transmission. Everyone is telling me to get the diesel motor. But I don’t want any emission issues. I’m retired & we bought a camper in 9/23. We’ve just started our camping season this year. Went to Branson Missouri & came back through Nashville Tennessee for a few days. (1526 miles driveway to driveway). We’re heading out again next week. I’m towing my 6100lb dry weight camper with a 2018 Toyota Tundra. It does a pretty good job with this camper.But I can see us upgrading campers in a few years.But in my mind a 3/4 ton truck would be better. I was always a GM guy,until I bought my Tundra. I thought it would be my forever truck, but here we are with a camper & traveling. I’m logging all my towing miles this season & going to see if it’s worth upgrading to a 3/4 ton gas or diesel. It will definitely be a GM if I upgrade.
We have a camper that is similar in weight. We towed it across the country with our 15 Tahoe. Had no problems with it. A 3/4 ton truck will always handle better than a half ton. And a diesel will always get better fuel MPG than a gas. But I'm ok with sacrificing a few mpgs for the less hassle of the gasoline engine and the cheaper up front cost. Yes a diesel is better for pulling, and I'm not saying it isn't. But for us it isn't necessary. And that's how I've looked at it. Very soon I will have the camper out of storage and be able to do a tow test to get some numbers
Love that light gray interior. Mine is the same body color but with black leather. This is my first brand new vehicle ever in all my 46 yrs. I haven't had a Chevy in 20+ years, and so far, I'm happy about coming back. Keep up your the good work
Thanks for the support! At first I wasn't sure about the interior color. I had only seen the online builder and it seemed very white and I was worried about staining it especially with kids. But I liked it alot when I saw it in person
I just got my 2024 gas LT, 300 miles so far I agree fully on your first impressions. Coming from a 2015 1500 max tow 5.3. It feels much peppier and the trans is always in the right gear unlike the 1500, hated the delay when when you step on the gas with the 1500. So far my mpg combined is 14mpg Love my new 2500!
@ I did not know that and I have a 2025 2500hd Silverado coming in January. Thanks for knowledge I didn’t even think of looking into that when I was doing research and test driving
I have a 2025 chevy 2500hd lt and my gas milage was 9 city 14 highway now its 8.5 city 11.5 highway i did change the tires from 17 to 20 but they are oem tires that came from another 2500
yes the ko3s on oem rims but since beggining gas mileage was at 14hwy which i was ok with. . dealership told me 18mpg but ohwell i love the truck im about to hit the 1,000mile mark
Ihave a 2024 3500HD PRO. Changed the filter at 1500 miles and the oil at 3750. Seemed liked reasonable points. Definitely had some metal particles in the oil. Didn’t know about the grease fittings. Will be checking mine.
@@slmjake I love it. Thing is huge, but I'm getting used to it. Difference between it and 2500 is minimal, price wise, but it's a lot more truck. Options I have are crew cab, 8 ft bed, off road package, steel 18" wheels, white paint, 5th wheel prep, snow plow package, 2 batteries, high output alternator (dealer screwed up - I wanted dual alternators), multifunction tailgate, AC outlets (400W, I believe) and flexfuel, so I can run on just about anything. Couldn't see spending an extra $10K for the diesel. I put a tonneau cover and an oil catch can on, and I plan on putting a Banks vented rear diff cover. Other than that, stock. Can't miss it in a parking lot. Thing stands out like the Rock of Gibraltar.
Did my first change at 1200 miles, just did the freebie from the dealer. I’m going to keep it to the 5k intervals as close as I can. The manual does say if you intend to tow heavy or long distance, do the first oil change early. I have a WT Z71. The Rancho shocks are meh but I’ll use them till they get tired and put in some 5100s. The LTX AT2s aren’t the most aggressive for off road but from what I’ve seen the tread life is superb, and they definitely aren’t loud. I don’t have the Gucci interior but this truck is QUIET. Windows up cruising down the highway it is silent. Another quirk with the 10spd is it sequentially shifts. I have found I can barely feel the shifts and she doesn’t seem to do much gear hunting. My fuel economy has averaged out to 13mpg over the 3000 miles I’ve tracked in my Fuelly app. That’s 75/25 highway/city with my typical cruise control set to 73 on the highway. And that’s a double cab long bed, me in the cab and a weatherguard full of tools in the bed.
That's great info! I'm also very amazed how quiet these trucks are at highway speeds. Tires do run very smooth. My oil change kit is on the way so I will be about 1200 as well when I get to do it
I have a 24,😊 2500 heavy duty with just short of 7,000 mi on no problems. No oil consumption. I get between 15 and 16 and 1/2 on the highway. I did lower the tire pressure. They had it set at 70 and 80 when I picked it up. Help with the ride some but I've had passenger's comment on how well it rides for a heavy duty truck!
Thanks for sharing! I've thought about lowering my pressures too. Mine was set to 65/70. I've thought about going down to 55 or 60 where I've ran other load range e tires and they ride nice and still wear evenly. Be sure to keep us updated!
Quick question for you old schools who know more about diesel trucks than I do. I’m looking into buying my first diesel soon and I’ve seen it gets around 18mpg with a 36gal tank. My calculations say I should go at least 600 miles fuel range before hitting empty. But I keep seeing videos where diesel owners fill them up and doesn’t seem to go over 390 fuel range on a full tank.
That calculation is a rolling average of current fuel economy. Because they can get 18, doesn't mean they always will. City driving and idle time really eat away at the average mpg calculations. Which results in such low numbers. Even using the key fob to remote start the truck, before the ignition is fully turned on, eats away at those average numbers. If you watch the fuel range on these trucks enough you can even watch the range go up, while you are driving down the road because of the rolling calculation. With my gas truck I am very consistently around the 500 mile fuel range when I fill my truck and I have a good mix of city and highway driving
The transmission is not built by Allison. It is a GM transmission that Allison allows GM to use their name on. Mine along with many other people are having issues with hard shifts from 7th to 8th gear. GM has issued a bulletin for it. PIP5971 is the bulletin.
That's interesting. I know I've had a harsh shift from 1-2 under certain conditions. But I'm under 4k miles so the trans is still in learning mode per the book. I've been purposely making it shift hard to learn and correct itself
Would you be interested in doing a tire pressure ride experiment, while the door sticker gives tire pressure numbers according to maximum axle weights allowed, with the weight of your truck as you went over the scale its not near those gross axle weights since its nearly an empty truck. I referenced the Toyo tire inflation chart as its easy to find but it would be based off of a standardized tire size and ply system. According to it you would be right on the line carry wise to use 36 psi in the front and that easily would carry the rear. Being that they are an LT tire the 35 pounds is also the minimum pressure to run at highway speeds. I know it won't help fuel mileage but would be interesting to see how running the minimum safe tire pressure would affect the ride quality over the current pressures you are running.
I've played with tire pressures before on vehicles. Ride quality will improve but handling will decline. Steering and back axle will start feeling wishy washy because theres not enough to keep the sidewall stiff. It's a Tradeoff. And this truck has tpms so I'd rather not upset the system
GM's OLM is quite sophisticated. It takes into account load and temps and a whole host of information. You can run it hard. The truck will account for that. Just follow the OLM and you'll have years and years of life in that motor. Oil is cheap insurance so what ever floats your boat.
The ten speed in gm hd trucks was developed when gm was still sole owner of allison and developed. Gm maintained rights to it in sale and kept the right to brand it as Allison trans even though not put together by Allison . But is and Allison tested and approved design is what I was told.
This truck has the 10L1000. Not the 10Lxx trans that's in the half ton trucks. And it's not the same as the one behind the Duramax being different part numbers all together.
I don't have any first hand experience with this engine. So my opinion is just based on what I see. I feel that if it was a bad engine, I would have heard about it being unreliable. It's small for an engine but makes big power. My guess is they use it for the people that just occasionally tow a small camper or a fishing boat on the weekends and just commute with it most of its life. The power and torque numbers are so high in the rpm band it's not a big workhorse engine. For pulling a V8 will always be better suited in my opinion. But that doesn't mean the 2.7 can't do the job. The 2.7 makes more power in more of the rpm band that most V8 engines from 20 years ago and those all did just fine back then
So far I have seen no oil consumption. Even checked it again this morning to make sure it had not gone down. I think the issue has been resolved with this model year
@@bobsokoloski9559 I have heard that a lot as well. Many factors play into what would cause it. I know I stuck to the break in procedure and had no problems yet
@@bobsokoloski9559 I'm a firm believer that you take care of the truck it will take care of you. But I'm sure most are not aware that GM has the dexos standard for their oil that they use. That's how they ensure quality oil is used to protect the engines. The 15 minute oil change places do not usually have that in bulk. So I'm not sure if that's where some of the reliability complaints stem from
Changed mine in my Ram 6.4 hemi around 850 , almost 4000 now gonna change again real soon . My first Ram , had GM/ Chevy for 20 yrs , last Chevy 2021 2500 was junk , love my Ram 2500 so far .👍🏻
@@adventureandrepeat They do have a set schedule in the manual, but I do not follow the oil change intervals they state. I prefer to change my oil every 5,000 miles. The manual says no more than 8000 miles, 350 hours, or 12 months. I use Mobile One full synthetic in all my vehicles. My wifes Durango RT, and my Camaro SS 1LE.
These trucks are shipped without grease in all 9 fittings. Most dealer service techs are not aware that the truck has grease fittings. (9) Also, most of the rear differentials are shipped 1-2 qts low.
Yea all the grease points did not appear to ever have any put in. I doubt this truck ever went thru a pdi before it was given to me. Just to clean up. Rear diff inspection has been on my list of things to do. Just haven't decided if I wanted to top off or go full diff change
@@adventureandrepeat I asked my dealer to do a full grease and check rear diff on PDI but I need to verify soon. (now at 480 miles of city driving) I show an avg of 8.3, best 11.6 mpg so far. GMC 3500HD SLT CC LB SRW
The pre-delivery inspection checklist has dropped all those service things from years back. The tech pay dropped even more. The PDI will have checks for current software and any service actions. The vehicle will be taken out of transport mode that prevents transport and lot storage battery drain by shutting down many features and changes the power down after door close time to 30 seconds or less. Modern vehicles , even with a keyed ignition "switch" , use the button or ign switch as a request, no direct control of power supply as it was for decades. All the features we have grown to love require the computer controlled power management, remote start being an example. @adventureandrepeat
Hell I didn't get 400 miles on my 2024 f250 before it had to go back in for repair but then again my tailgate doesn't open all on its own! New vehicles are just crap but charge twice as much then 3 or 4 years ago
Yea, I haven't gotten any official notice for it yet, but I did hear there was a tailgate button recall to fix it. I have not had the issue yet. And it's been a wet spring in Michigan
That's something I have been happy that they didn't do. Being the same block as the 6.2 with the redesign I figured it was only a matter of time before it's incorporated
23 silverado 2500 HD live at beach with stop signs every 150 ft or so....even boulevards are littered with lights and stop signs...9 mpg On highway 18-21 @ 65 mph For a big truck not bad These things want to keep moving....stop and go it doesnt like
Get back to us when you drive it in real world conditions with some grades, wind and more than just you plus some child seats in it looking for mpg numbers. Then, actually calculate the mpg between full tanks and don't just rely on the dash numbers.
We value your feedback. For that exact scenario you are referring to we encourage you to check out "the fast lane truck" where he has a video that shows just that
For some, an electric vehicle makes sense. I know people that have them. The biggest advantage they have is if you have solar panels on your house it's free energy. And as a commuter vehicle to work and back it's more cost effective than a regular car. So in the end it's great for some and they have a place, but for our family it would not be effective with the current technology

All the features we have grown to love require the computer controlled power management, remote start being an example.

It's not an Allison, it's built in house by GM, rebadged as an Allison for marketing.
I'm sure Allison gets a good paycheck for having their name on it
gm owns Allison
@@RobMcqueen-t5t No they don't, not since 2007.
It's a allison !!!@
@@scoretime1 Only the fender badge is Allison.
Hell I didn't get 400 miles on my 2024 f250 before it had to go back in for repair but then again my tailgate doesn't open all on its own! New vehicles are just crap but charge twice as much then 3 or 4 years ago
Yea, I haven't gotten any official notice for it yet, but I did hear there was a tailgate button recall to fix it. I have not had the issue yet. And it's been a wet spring in Michigan
Oops I forgot mileage. Definitely got better after 1,500 miles
Was that after an oil change?
No GM HD ever had cylinder shut down.
That's something I have been happy that they didn't do. Being the same block as the 6.2 with the redesign I figured it was only a matter of time before it's incorporated

live at beach with stop signs every 150 ft or so....even boulevards are littered with lights and stop signs...9 mpg
On highway 18-21 @ 65 mph
For a big truck not bad
These things want to keep moving....stop and go it doesnt like
I'm honestly very surprised how well they do at highway speeds for how tall and heavy these trucks are. Those are great numbers to see!
65-15mpg ?????
Initially when I started going 65 my overall average was 15mpg. But it kept going up as I was driving
Wow that’s devoid of any facts.
We value your feedback. Where do you think we have room to improve on?
Get back to us when you drive it in real world conditions with some grades, wind and more than just you plus some child seats in it looking for mpg numbers. Then, actually calculate the mpg between full tanks and don't just rely on the dash numbers.
We value your feedback. For that exact scenario you are referring to we encourage you to check out "the fast lane truck" where he has a video that shows just that
That one UGLY TRUCK! Front end is crappy looking.
Nuh uh! Yours is ugly. See how that works????….😂
We value your feedback. Which truck do you think would have been a better option?
Such a horrible looking truck

looks like $3-4 dollar fuel is here to stay so let's get those AFFORDABLE electric vehicles to the people!
For some, an electric vehicle makes sense. I know people that have them. The biggest advantage they have is if you have solar panels on your house it's free energy. And as a commuter vehicle to work and back it's more cost effective than a regular car. So in the end it's great for some and they have a place, but for our family it would not be effective with the current technology
