I hope everyone is having a good weekend. Today I dive into the 3 most common issues on these Chevy 6.6L gas engines.
1. Oil consumption
- these engines have been seeing some oil consumption happen, it seems like the oil control piston rings are letting oil pass up into the combustion chamber and getting burnt. there is also possibility that the PCV is letting oil into the intake and burning it.
2. Direct Injection Carbon Build-UP
- these V8 engines are direct injection and this can result over time of the intakes getting full of carbon deposits resulting in less air flow getting into the cylinder. this will lead to lack of power, rough running engines and even missfires
3. Engine Ticking Noise
- owners have been reporting odd ticking noises coming from the engine. this does seem to be some sort of mystery even the dealership are having a hard time pin pointing. I personally think the noise has to do with the fueling system or low octane fuel being used
4. Lack of Acceleration
- I've heard people complain that this truck does not have good enough acceleration and well it is not the fastest truck I've driven but it's not supposed to be. this engine does a great job pulling under load and I don't know what else you could ask for out of a work engine.
Hope you guys liked the video!

I've owned a couple of these trucks now with the 6.6 gas. I tow a decent sized 5th wheel about 12,000 lbs. Probably half of my mileage is towing. I personally haven't experienced any oil consumption on either truck. I believe the oil issue was limited to a certain number of engines, not just the 6.6 in general. Otherwise a solid engine and perfect for those who don't want to spend the money on a new diesel. Love my 6.6 gas and that's coming from someone who has owned both Cummins and Duramax 2500/3500 before.

That's exactly that the 6.6L was designed for, to be a very reasonable alternative to the diesel engine and not have to deal with the modern diesel headaches that come with those engines. but the 6.6L is a complete work horse and I think people are going to like them.

My 2022 GMC 2500HD has had a catch can from new, uses no observable oil between changes per dipstick, but the can grabs about a tablespoon or so every 1000 miles or so. I also think this engine takes longer than 5k to break in, it continues to get progressively smoother and quieter with 16k on it. The first few thousand miles it had some clatter that was concerning. Mileage is very good for a 4x4 HD truck, averaging 15.9 in mixed driving, close to 18 on longer trips. Excellent value in my opinion.

Engines that get worked hard right away when new are probably a lot less likely to burn oil than ones that are "babied" when new. The higher cylinder pressures of being worked hard right away are likely to seat the rings in right away and eliminate the oil consumption issue early on.

I have had the same basic truck under my rear since 1982. The 82 ,85 ,87 were 3/4 ton -2 whl drive 8ft bed ,the 89 was the first 4 whl drive ,2004 was extended cab 4 whl drive and the 2023 is a Carhart crew cab and 6.5 bed .The 2023 is the best riding and the most fun to drive of all them .As of today I have driven just over 12000 miles it has burned about a quart over 4000-4500 miles .It has towed my 7000 lb boat and trailer with ease, this is my final truck, and it is equipped as my toy as all the others were just a cut above a work truck. For all of the last 40 plus years I have changed the oil at around 5000 miles and despite having fully synthetic the oil percentage has reached 15-18 percent at about 4800 miles so much for the 7500-mile syn benefit. My dad use to say the more options in a vehicle the more headaches down the road only time will tell .I have gone from a 180 hp 350 to a 6.2 liter 300 hp to the 401 hp 6.6, they were equipped with a turbo 400 3 speed ,the first gen 700 r 4 abortion to a legit 4 speed overdrive now to the 6 speed .Had my 2004 not rotted out from under my feet I would have waited for the 10 speed however the I have found the 6 sp smooth when it shifts but it does seem to down shift a little too fast when slowing down to take a highway exit. When I was running my shop and constantly putting miles on the odometer I would use the local quicklube but the cash outlay for the 2023 Carhart is such that I use the selling dealer service shop for the oil changes .The trucks service history will be there if I have a warranty or out of warranty issue .GM held that fact against me when I had a brake issue on my 2004 2 months after the warranty ran.GM claimed that I was not sufficiently loyal even though the shop and family were all GM brand vehicles. As far as mileage 11-12 city my best 50 mile mark is 17.4 .I know I bought 3'4 ton truck not a Toyota Corolla so the mileage does not surprise me since 14 -16 was all I ever average with any of my trucks .

I just bought a 24 gmc with the 6.6 gas. I love the truck. I basically live in it for work and love the ride quality and interior. But in your shoes I'd go with a Superduty. Those Ford engines are proven. Either the 6.2 or 7.3 depending on how much you need to tow. But the other big thing is Ford's drive train. Solid axles are more reliable and much stronger. The newer superduties all come with electric rear lockers, and they have manual front hubs in case the automatic 4x4 fails. They just don't ride nearly as well as GMCs. My last two trucks were a 19 and 20 powerstrokes. I just got sick of dealing with emissions problems, and this GMC 6.6 gas will tow the occasional 18k that I need it to.

I own a 2021 6.6 gasser and while your video was spot on addressing the concerns and observations by some it also reflected what a tremendous step up this is even mated to the 6 speed. It was not that long ago the Duramax itself only produced 397hp mated to a 6 speed and of course torque was much higher however for the performance and capability for those like me that pull occasional heavy loads and daily commute the remainder this truck has been everything I could ask for.

I just bought a 2024 Z71 2500 HD today. I addressed these issues with the head tech at the GM dealership. In the last 2 years, he said they have had few issues with any of them. 2 front seals blew out the front of the transmission at 30k a couple of years ago. Both were covered under warrantee. He also recommended changing oil at 3k miles. Growing up in a racing environment. cars, Harleys, and marine, I've know some very good engine builders who most swore by Seafoam and Marvel Mystery oil, which both are on my shelf today. I asked the tech about using these in my new truck, and he replied obsolutely. I'm 64 and have used these products for years in the old big blocks, and pretty much anything with a motor, for reducing carbon buildup, and ping noise. I'm posting this because I've read a ton of reviews, and none of the comments I read mentioned this. Yes there may be other products you may prefer, but my point is to use some preventative maintenance.

@donrichter3523 5 ай бұрын

@scottmartin5671, Seafoam or Marvel Mystery oil won’t do shit for this engine, assuming you are adding it to your fuel. It’s direct injected, so the injectors are downstream of the valves. It won’t clean the valves. Now the injectors can still carbon up, but for that, occasionally use Chevron Techron or other cleaner with PEA.

DI motors have that ping or tick noise. I think they can run so lean that some detonation is just the way it is. With the DI the difference is you get this symptom in a small range of rpm's per the situation, not like the old motors that pinged across the board when lean.

Dont know if anyone has mentioned it, but consider the constant trend across the industry to lighter and lighter viscosity oils. Maybe in an attempt to reduce parasitic loss and freer flow. Think HP numbers and EPA/Cafe regulations (higher mpg). A slightly heavier viscosity oil would/should reduce consumption and increase lubrication. Think back to when you went from 30wt to 40 wt as your engine got more miles years ago. Just a line of thought.

Agreed. If this truck engine is doing considerable work (towing), I would use an SN-rated 0W-40 or 5W-40 oil. These two oils are outstanding, 1) M1 FS 0W-40 and 2) Premium Blue Extreme SAE 5W-40 Full Synthetic (SN-rated).

Yes and no, I would slowly work the engine in for the first 300-400 miles. after that I would start to load up the engine. let the engine run completely through the RPM band all the way to redline and after 500-600 miles I'd feel confident towing without hurting the engine. But each manufacturer will have a general break in procedure.

That motor and truck has been flawless with no significant oil burn through 60,000 miles. Of that, approx. 20,000 of that is towing heavy. I think you’re being a bit tough on this motor given its wide acceptance. With respect, I did not subscribe due to the negative vibe for this truck and motor with zero positives, which are many, evidenced by the subsequent comments here.

Nice review. People love to hate these 2020+ GM HDs, especially the 6.6 gas versions which confirms that they are a total smash hit. You see them everywhere and real actual owners overwhelmingly love them. Anyways, my 2022 2500 LT Z71 crew cab, short bed with 20” wheels has a little over 33,000 miles now and so far it’s been so good. Zero issues (I have had the brake squeal/squeak but I hardly consider that an issue). No oil usage. I do change my oil at 3,000 miles and always get people telling me that’s a waste. My response is oil is cheap and I also don’t have an oil usage problem. Interestingly enough I probably did have over 5,000 miles on my truck before I towed my racecar. I got my truck December 14, 2021 and race season was of course over until about April or May of 2022. So I definitely had over 5,000 miles. I’d be curious to see if the carbon buildup is truly a problem. GM has been using DI engines in trucks for 10 years now. I’ve never seen a complaint with that about the half tons on any of the Facebook groups. So I’d be interested to know if it’s truly a problem. You are also 100% correct about the power. It is laughable when people say that. The 6 speed tuning and throttle position tuning in general is the culprit because when you are driving them normal, it wants to get in 6th gear as fast as possible and the computer will allow the truck to “lug” and not downshift as soon as you would think they would under light throttle. You mash the gas though and they will go. Now the 6 speed is a little limited on gearing for wanting to do 60 mph on 7% grades. 2nd is just too short (63-64 mph top speed) and 3rd is just too tall (96-97 mph top speed). The 10 speed has corrected that “problem” however. Good review though. The ping is something I haven’t really seen come up much as a complaint in the truck groups. Maybe one or two times. Oil consumption and brake squealing is a daily topic though lol. Most of the oil consumption topics are guys saying they heard they use oil and wanting to know if they truly do.

I doubt these trucks will make it to 100k without major problems or a transmission change. And I’ve pretty much been a Chevy guy all my life. I’ve known too many guys with tranny problems on late model trucks, not to mention when I had to replace the tranny on my 2005 Silverado at 45k and never had a trailer hooked to it. If you need a work truck buy a Ram 4500 with Cummins. They’re not perfect but I had a 2014 that always had a 40’ gooseneck on it. Put 150k on it with no major problems. Pulled 20k lbs all the time. They ride rough without a load but that’s the nature of the beast.

@@bradsteelguy9140 I think you’re entirely wrong about these trucks not making it to 100k lol. There’s examples out there already over 100k (some over 200k) but even without that the 6L90 transmission has been used in HD trucks since the 2007 model year. I’m not saying it’s perfect but it’s been around for a long time and at the time of the 2020 model year released it was GMs least warrantied transmission. Now the 2024 has the new 10L1000 Allison so we will see how it does. And there’s just nothing widespread that you can find problem wise with the 6.6 L8T engine. If there was some kind of widespread problem (like the terrible lifters in the 1500s, or the cam and lifters in the 7.3s) at this point it should have showed up. Oil consumption is by far the biggest complaint with the trucks. I have my theory on that too but there was some early 2020s that actually had in proper cylinder wall honing and some piston ring problems. Some people are saying the 2023-up use different rings now too but I don’t know about that one. I know my 2022 does not use oil but I change my oil at 3000 miles. And outside an actual cylinder wall problem or ring problem I think the 5000+ mile oil change intervals is the reason for using oil. The manual says change then at 7500. That’s too long in my opinion.

It has always been the case (as far as I've been aware) that you need to let the engine sit before checking the engine oil. Ideally, it should be checked when cold as you'll never, ever get an accurate indication. The auto on the other hand(provided there's a dipstick) should be checked when hot.

Regarding the front of the truck, it's huge. The whole truck sits up so high. It's bad when you have to crawl up on the engine to check the oil level. You must be around 5'9" . You need a ladder to access the engine bay. I'm 6'3" and would have trouble reaching in that engine compartment. A slow truck is my 1988 454 tbi Suburban w/ 3:42 axle. Terrible mpg too. but I knew that when I purchased her in 96. We have 93 octane in NC, why only 91 in Canada? Have a great week Alex.

Haha I mean with work boots on ya 5'9 but closer to 5'8. I couldn't reach to dip stick if I tried without getting all up in the engine bay. we do have 93 up here but just not at all gas stations, you can find it everyone now and again but 91 is much more common to see.

I don’t think the half ton would get the job done suspension wise long term, that’s why I’m looking at something bigger but don’t want the maintenance cost of a diesel. Any thoughts?

The burning oil issue is on the 2020-2022 6.6 gas not all of them have the issue some do but after 2022 the issue got resolved and people in 2023 and 2024 models are not experiencing this issue it’s kinda crazy that the creator of this video can’t do basic research on the oil consumption issue. I would link to the GM forums but KZfaq doesn’t like links. Ram has cylinder deactivation on their 6.4 which is junk and fords 7.3 v8 are having lifter delaminate at 40-60k miles with 6 pounds of oil pressure at idle I don’t see this guy jumping ford or rams ace considering all manufacturers have their issues.

Like you, I needed more payload, however, which is why I got the Sierra. I haven't experienced any oil consumption issues yet (only about 4500 miles on it now) or any weird noises, and it drives so smooth with the 10-speed. If Toyota had HD trucks I'd probably have stuck with them (except the current-gen Tundras are pretty hideous), but so far so good with this GM L8T.
