Lifter failures, btw, were only on the 8 cylinder engines with AFM/DFM. No lifter issues with the 2.7 because it uses a different method to control the cylinder deactivations.

OHC engines don't have push rods or lifters. The issue with the AFM on the GM V8s and V6s is primarily due to failed lifters.

[@ojustracing]

Alex Yes this motor has a lot of Tech in it. But you might want to look at the internals of the L3b before making a blanket statement about AFM lifters failing like the v-8 versions. This engine is DOHC that uses camshaft follower and hydraulic lash adjusters. Nothing in this engine is like the AFM lifters/system in the 5.3/6.2.

[@GettysGarage]

I Imagine the AFM is a different set up in this engine based up the 3 phase cam shaft. but a cam followers or a lifter does the same thing more or less. the v8's are all hydraulically adjusted as well. It's no secret that the 4 cylinder engines are having valve train failures. weather it's directly related to the AFM system that could be a debate but something is causing these issues.

A lot of people on here crying about the old days of truck engines, and how concerned they are about having a 4 cylinder in a full-size truck. The reality is that ALL engines, big or small, regardless of application, have issues. Some more than others, but issues none the less. Yet somehow every brand loyalist, self proclaimed expert, and insecure large displacement bubba, has their concerns about anything new or smaller than 5 litres. Well, the old days are gone. Nobody asked for the 2.7, but we got it, and it seems to perform. Some people have had issues, others have had none. It’s new and only time will tell. We all miss the good old days of reliable, large displacement motors that are easy to work on and maintain, but that is the past, not the future. The world is changing.

[@BrewReview]

This gives me a little hope. I *just* bought a Colorado Z71 in part due to the same reasons and I noticed about 16.5mpg all highway on the way home from the dealer. Plan on towing landscape stuff for short distances regularly.. I sure hope that MPG improves and this motor doesn't explode itself as she breaks in.. I'm very concerned as to the direction of todays's autos, these days we are kind of stuck on small turbo motors unless you bump up to full size which largely is more inconvenient for most people. Unfortunately, manufacturers are going the "tech+small engine" route for the foreseeable future so you're kind of screwed with that either side of the brand coin one chooses.

[@jessesellers9873]

I gotta say this. I bought one of these a few years ago. It has been great. I was very skeptical and thought it would be a quick trade in. I’ve been driving tacomas for years and planned on getting another one. I rolled the dice on the Silverado 4x4 2.7L. 52k miles later and I’m still averaging 19-21 MPG in town and 24MPG on the HWY with long interstate trips giving me 25-26 MPG on 87 octane fuel. I put some premium stuff in every now and then if the price is low, which is almost never. I also change the oil every 3,500 miles with cheap 5W 30 dexos oil. I do this because you have to keep an eye on oil levels in these Chevy’s that have cylinder cut offs. My only problem have been I wish it had the smother 10 speed transmission and I wish it sounded like a V8. Hell I don’t even care about the sound anymore. I will probably trade it in a few more years just because that’s what I do. If they still have this engine in a few more years and it continues to hold up I would get it again. At this point I worry more about the transmission than the engine, but it’s doing fine as it is, just wish it was smoother.

@@SD-pi9co just like everything else, common sense tells us some regulations are necessary. US air quality was mostly cleaned up by the early 90’s. At a certain point, you get diminishing returns, the juice is not worth the squeeze. The engines I mentioned were not creating anything remotely close to 1960’s urban air or current air quality in Bangkok. From a practical perspective, the air quality was fine when these engines were in place. Another item is diesel engines, which have unreliable emissions equipment including DEF, EGRs that increase EGTs, among other systems that are horrifically expensive to fix. Most people don’t care, but they don’t realize EVERYTHING gets moved by diesel trucks in the US. When diesel trucks don’t last as long and have far more expensive and frequent maintenance/repairs, the cost of EVERYTHING goes up as a result.

[@katietrotter9374]

Anecdotal but here’s my feedback after owning it for two years. It’s been nothing but reliable and I like the way it drives better than the other engines as well. I live in colorado and regularly drive it at freeway speeds at high elevation with dirt bikes, mountain bikes, kayaks, landscaping material and equipment, etc. I don’t tow boats or heavy trailers, neither do most truck owners. For the average full size truck driver that wants a large cab and a good sized bed, it’s a great truck. Go buy your diesel if you tow boats up mountains. Or if you just drive it to work and your kids soccer practice, but you want to pretend you tow a lot. For the rest, this seems like a great truck so far. Maybe I’ll be proven wrong in the future.

I've seen dozens of 3.5 ecoboost f150s with over 250k miles. Ford's v6 ecoboosts have forged internals, hypereutetic pistons, 6-bolt mains, and beefy piston rings. If GM built their 2.7 to similar durability standards, it should be able to go 250k+ miles with proper maintenance. Turbos and smaller displacement do not automatically mean poor longevity. It's all about how the engine was built. Diesels run higher compression and 10-20psi more boost.

The 3.6l V6 and 2.8 Duramax diesel have sadly both been retired, so it’s the only engine available but it comes in different states of tune. It seems like a good fit for the mid-size trucks with a better power to weight ratio than in the full size trucks. But, in my opinion the 3.6l was a great fit too, fairly bullet proof, plenty of power and the fuel economy was nearly identical to what these new four bangers are getting. I’m just guessing but maybe GM wanted to advance the technology and increase low end torque? But it’s just not really an efficient power plant either so it remains a mystery why THIS is the future?

What do you mean it’s not common for Turbo Gas engines to produce torque like that? The 3.5L EcoBoost makes 420 of its 470lb-ft rating (90%-ish) at around 2500 rpm. Which is not very far off this 1800-1900rpm feat of this 2.7L 4 Popper. The 3.0L EcoBoost reaches 400lb-ft (90% - ish) @ around 1400rpm, and makes 440 around 1800rpm. Which is actually better than both aforementioned engines. The 2.7L EcoBoost makes 350lb-ft (90%-ish) around 2700 rpm but actually makes torque FASTER than the 3.5L at lower rpm having roughly 125% more torque than its big brother 3.5L @ the same 2100rpm. Either way that’s three engine examples that out achieve VERY similar to the 90% torque at 1800-1900rpm achievement that this 4 cylinder boasts. Granted lol yes they are all 3 FORD engines… 🤷🏼‍♂️ Now some BMW higher revving Turbo I6 or Twin Turbo V8’s they show curves around 4000-6000 rpm’s for peak torque values. But I think that this achievement is more common that it is rare. I mean am I missing something ?

I have a 2020 Silverado with this engine in it and so far I like it a lot for it being a 4-cylinder in a big truck. I have had issues with mine but it has all been failing sensors and other plastic computer junk which have been replaced for free under warranty. I haven't had any mechanical issues so far, but there also isn't much mileage on it due to it being a lease vehicle. When I first got it in August of 2020 I was originally running high-octane gas in it as the norm up until the gas prices skyrocketed. Now I just run normal 87 and top up the tank every Friday so I don't have to buy as much. I'm sure adding an octane booster into the tank would help for less than buying high-test fuel. As for engine longevity I do my best to buy the best engine oil I can get my hands on. Since my mileage is extremely low I'm only on my second oil change. The first oil change was done at the dealer to take advantage of a free oil change. But when it came time to do a second oil change I was happy because the ACDelco oil they use is crap. The engine felt like it didn't rev clean when I was driving around. With the second oil change I bought some full synthetic STP and it runs much smoother than it did with the ACDelco junk in it. When the third oil change comes around I'll be switching back over to the Royal Purple I've been running in my previous truck. From what I read on RP's website the stuff I was previously running is formulated for newer aged vehicles as wall as those with turbo's. So that might help with longevity. As for current gen 5.3's I will have to disagree with them being good engines. Which hurts me to say as the 5.3 is one of my fave GM engines besides the 327. The 3rd Gen 5.3 out of my previous 2004 Silverado was a great engine with minimal problems. After 2005 when they started going ham with the AFM rubbish the 5.3 stopped being good in a stock config.

@@calebniederhofer6529 If it was ran for 100K miles on nothing but conventional oil then switching oils would be a no no due to worn seals and what not. But since it has less than 15K miles on it and nothing but synthetic gets ran in it switching oil isn't going to bother it. Especially since you can't control what a dealership puts in it when a family member tells you to take advantage of a first free oil change. And to be honest it's a modern turbo'd engine with tighter tolerances so it shouldn't even have conventional ran in it in the first place. I run AmsOil and Royal Purple in my vehicles, if I run anything else it's because I don't have the money for my normal choices at the time and I get the next best thing that isn't as costly. Switching oil is better than no oil changes at all. So far it has only had two oil changes done to it and the third is coming up soon so it's getting Royal Purple this time around and will continue to get it there after.

That's with city trailer towing, new truck idling while playing with gadgets inside, and a 1200 mi road trip with 78 mph speeds. -23 Crew cab, 6.5' bed 4x4 is getting better combined mileage than my '17 regular cab long bed 2wd 5.3 truck (the '17 truck was usually 2 mpg off of actual mpg) Only issues: transmission sometimes clunks down to first gear only after hitting the gas from a stop. The audio (both fm radio and from audio book from phone) has stopped working 4 or 5 times. A restart of the truck fixed it.

This never gets mentioned, but this engine was designed by GM to replace their 4.3 v6 base engine, not their v8's. It destroys the 4.3 in every metric. The fact that you compared it over and over to v8's shows how impressive this engine actually is. Compared to the 5.3, it's cheaper to build, weighs less (more payload!), tows almost as much, and feels much stronger in day to day driving due to that low end torque. It also gets better city MPG, but yeah on the highway n/a v8's can still do quite well especially when they start dropping cylinders (mds/afm/dfm).

[@robertannable9584]

This is truly a great point. Great video, yet this is the real lead, and it was buried deep in the long video & never discussed.

[@GettysGarage]

Fair point. the reason I guess I compared it to the V8 is because it's the other gas engine option. I felt like that's what most people are going to be interested about. whether to settle with the 4 cylinder or step up the v8. the tech itself is actually a little wild, but it does just concern me about longevity and reliability. but only time will tell!

[@TomcatandSons]

That's a good point. I think this platform is decent for those that care about mpg. Maybe better suited in a midsized or suv. What kills me is the AFM. Why the AFM? Its a ticking time bomb, it will cause engine failure. Believe me. Just spent a month this past summer removing my 5.3 l83 out of my Silverado due to lifter failure right at the 100k mark. Ended up fully deleting the afm with a texas speed delete kit with a stage 1 cam and ls7 lifters and a handful of other odds and ends while I was there. What's interesting to me is mpg with afm was at best 19mpg highway. After I deleted the afm I now get 21.5mpg. So why afm? If a better cam and lifters can achieve those results? I'm fortunate to have mechanical ability, tools, shop etc to fix most anything. But the average guy better stay in warranty. Or have deep pockets.

The new GM Product’s are plain junk.

@@ramiroescamilla7263 I drove Chevy trucks most of my life - until 2019. Hate to say it, but I agree.

[@tomm1109]

You get much better city mileage and use a lot less fuel when idling with this motor. That is the big advantage. Strictly highway driving it is about the same as the V8.

[@Oldrush]

The reason they are using a 4 cylinder instead of a 6 is material cost savings. There are engineers that spend all there time reducing material. They study making every screw one thread shorter. Or like the ignition locking pin that went horribly wrong when they shaved 1/4 mm. Anyone remember car’s shutting off and causing accidents? GM’s fix, don’t put anything extra on your key chain. So imagine the lustful excitement when they get to get rid of 2 cylinders and blame it on epa smog regulations.

[@DKLabs99]

lol I remember the service tech telling me not to put any house keys on the key fob, only the key for the car. I was like, what?

[@henryclark5486]

I have a 2009 Silverado 5.3 with 243000 miles on it. I've replaced one ignition coil and that's it. I pull two different boats with it pretty often, and it feels like it hasn't lost any power. It's really been a good one! And it's showing 17.4 overall miles per gallon.

[@GettysGarage]

those earlier 5.3's were solid engines!

[@paulbenderavich3833]

Great Information. This engine is better suited for GMs midsize suv lineup not a half ton pickup truck. With the cylinder deactivation/ fuel management, history is destined to repeat itself for those old enough to remember Cadillacs 4*6*8* engine.

[@logan9758]

Chevy should bring back the 4.8L and use that as the base engine and have a lineup of 4.8L, 2.7L, 5.3L, 6.2L, 3.0L

[@catinthehat5140]

While I agree with you mostly that Cadillac was a long time and before computer controls

[@jamesdumas6602]

What new truck engines are NOT port injected nowadays. On my 2019 6.4 Dodge Hemi Challenger, I installed a Catch Can and drain out a couple of ounces of oil every 2 or 3 thousand miles. (On my 6.4 Challenger, I get 22-26 MPG turning only 2000 RPM at 80 MPH.)

[@chevy_dave]

It’s overhead cam, it doesn’t have lifters to fail

[@dustyroads834]

I have a 2022 GMC 3500. With a 6.6. Welder , 100 gal fuel tank and big tool box in the back all the time and I’m getting 16 mpg and never on a highway. All secondary roads. I love it…….. so far. Only have 15 k on it.

[@SWATT101]

Does it come with a spare...engine...

[@Stanging84]

Exactly 💯🤣

[@FredRTP96]

This active fuel management on the 2.7 isn’t as present only under very very light loads or low speeds. For most part these 22+ 2.7 in my experience having 23 canyon with 2.7. It doesn’t really go into “eco” mode is what is called not AFM. Now DI, your worries can be solved with simple methods . Such as running additives depending on how often vehicle is used.

[@DyingCatalyst]

AFM on a 4 cylinder, this cant go wrong, not like they have a history of it.

[@GettysGarage]

It's all about the the final fuel economy number in the brochure.

[@mikee7241]

If I remember I do know there is a company that sells a mod to delete the AFM.

[@rolandthethompsongunner64]

I’ve been waiting on a review of this engine for some time thanks.

[@tbup-north8718]

curious to see how this holds up with fleet drivers !!

[@carlcampbell6827]

T&B Up-North - I think these trucks would be too finicky for fleet use.

[@goosegun6213]

I have 7500kms on mine and I have got as low as 8.8 litres / 100 kms I regularly get 10s my all time driving over 7500Kms on it is 13.2 that includes 5 trips with the decoy trailer this yr and lots of city driving as well.

[@TIREDOFEVIL]

What concerns me is that you stated that it has a 9,000 lbs or so towing package. So when do you think that this package will get out of boost doing that, I think maybe going down hill, can't wait to see the uninformed be shocked that it doesn't get 17 MPG. Seems far too complex for what it is, a lot of potential for engine issues and yes, put me down for a large displacement engine turning low rpm's to last a lot longer, just my two cents.

[@RFRUS]

I love mine and got an average of 23mpg round trip from Bend, OR to Sacramento, CA with 6K on it now. That is amazing vs. my 07 Silverado 5.3L which on that same trip made 14mpg. My dad told me one thing that was true,...."buy a truck and drive it like a car and it will last forever". As I don't really tow anything and am retired I suspect this will be my last ICE vehicle.

[@danhambrick6331]

Why didn't Chevrolet just put a turbo on the 4.3L?It has been around for decades....😁😁

[@JoeTeer]

Emissions, plus having a powerplant they can use in multiple platforms

[@jay5566]

They did, 30 years ago

[@riccardotumewu123]

Note on displacement theory. GM could be thinking about export market. Some market tax is based on displacement. Usually 3.0 is considered a new tax bracket.

[@Ck-ed9qy]

Alex - get a new 22+ Tundra and review it - please! The new 3.5 TT engine…I feel won’t live up to the legendary benchmark of the 4.7 and 5.7 v8’s! I’ve got 300k on my old 2008 Tundra 5.7 and nothing ever goes wrong with that damn thing, nothing! It’s like a cockroach…can’t kill it lol. Best vehicle I’ve ever owned - period. (…and I’ve had gm/ford/dodge gas jobs too). Also have two newer diesels…an LML dmax and a 1st gen 6.7 PS. The Ford 6.7 is a maintenance nightmare…the kind that makes you piss the bed. Lol

[@OfOld]

Shop has an 08, 10 and 13...all over 250k and NOT ONE issue with engine...that is remarkable considering they tow pallets of brick and skids

[@MrChadx1]

Don't forget the Tundra 4.6L V8 that replaced the 4.7L. It's even better than the 4.7 in my opinion. My 2013 has the 4.6L and it is simply a great engine. Hauls around our small to medium trailers (fishing boat and enclosed trailers) easily as well as our slide-in pop-up pickup camper. Runs about one gear lower than 5.7liter would pulling the same loads so I get the same mpg as a 5.7L when towing, but when running empty, I get 18 - 20mpg on the highway (hand calculated on 300+ mile trips) depending on if I drive 80mph or 70mph (80mph speed limits here).

[@jayblanc9852]

I've had my 2022 Chev Silverado 1500 custom for about 10 months now. I have put around 15 K miles on it. only problem I have had is a sparkplug failed and it started to misfire. Dealership fixed under warranty. I had to tow my sons 97 F150 back from TN and the gas mileage sucked bad. But I am still happy with the truck as a whole. One thing I do hate is the auto shut off after a while of running or on accessory, If I am trying to listen to music while working on it or something.

[@louisbabycos106]

Be kind of cool to have this as a crate engine in both FWD and RWD APPLICATIONS.
