I think it comes down to just how you drive and how much you stay off both pedals. I've been able to get 25mpg with my 5.3 on the hwy with the AFM disabled but also not using cruise control. I think the 5.3L might even be the most practical of them all and the 6.2 being the hot-rodded version of it. Great videos!
I have a 23 Silverado High Country with the 6.2L. I love this truck, it rides like a dream, it’s quiet, and when I keep my foot off the gas pedal I get really good gas mileage 20 on the low end and 23 on the high end.
My dad was a Chevy guy until he died guy and then had a 2010 5.3 that was trash, not only the engine but the tranny needed to be replaced and all kind of electrical issues. Then he got a brand new 2017 Silverado with the 5.3 and had fuel injectors go bad at 16k miles. And it ran like crap, was slow towing, and had other problems. He traded it in for a 3.5 eco boost and couldn’t be happier . 3 years later zero problems and a million smiles every time you lay into the gas. I ask him if he misses the bow tie and the v8 and he always smiles, hits the gas on the eco beast and says what do you think?? He’s a ford guy now.
I wanna see you test a Ford F-150 with the Powerboost 3.5L engine and see what it gets, I have one in my 2023 F-150 King Ranch and love it. 20,000 miles and no problems so far. Ive seen as high as 35 MPG (Granted this was 10 miles averaging about 30 mph with no traffic) but ive averaged 24.7 over the life of the truck. I normally get about 22-23mpg on the highway at 80MPH and around town I normally see anywhere from 25-27mpg, love this truck and can easily do 700 miles in one tank of gas!
Hell yeah! I was iffy on the high speed hwy mileage until I rented one a few months ago for a long family trip out West. Holy shit, I was getting 22.5-23 going 80 mph! It did go down on the return trip though, just above 20, but it was also in the heat of the desert. If only Ford offered a 5.0L hybrid-wishful thinking but regardless, after renting a Powerboost seeing how utilitarian it is, I’ve made my decision. It just pisses me off that Ford keeps messing around with the trim and equipment packages and making them more and more expensive each year. I may have to buy used, cu
Hi Alex. Great engine the 6.2 l; but I think the main headache "DFM". And the 5.3 l; it's enough and fabulous fuel efficiency, especially when towing is not frequent. I prefer the 6.6 Duramax to hard work. 😮 Big HUG! 😮
I can’t wait to eventually get the Lz0 on these towing and fuel economy tests. I work not be shocked if it ends up on top. It’s my favorite engine I’ve Driven in these half ton trucks
I test drove one before the 6.2 test drive and coming from a Hemi Rebel the acceleration on the 3.0 was abysmal. I really wanted to like that engine and to be honest I wish I had gone that route. A throttle tuner would help the sluggish acceleration a bunch!
That fuel octane note in the middle of the video is hugely important. Your cost per mile on a lot of gas 2500 trucks all of a sudden become alot more favorable when comparing say the Chevy 6.6 gasser 2500 vs a 6.2 1500 with a max tow package...arguably two trucks one might buy for a similar sized trailer/use case.
DFM is literally cancer to these engines. If you keep it long enough it has a 100% failure rate to where you’re going to be replacing rings, pistons, lifters, camshafts, and the bill will be between $4000 and $5000. How do I know? It happened to me. Any fuel savings you have over the life of the engine go right out the window.
I had this 6.2 for about a week and actually really really liked it. More than I thought I would. But, until the lifter issues are addressed concretely. I’ll never own one unfortunately.
My 2024 6.2 Trailboss has a 10k fuel average of 17.4 mpgs. Factor in that i tow a 4-5000# trailer a few times a week so a rough guess that 2500- 3000 of those miles were towing. I'm totally happy with the mpg's and i drive very sensible most of the time while having fun off road and some spirited acceleration blasts. Sure i hate the DFM because of the poor reliability but I'll say i like the start/ stop because i can hit the switch to turn the system off when i don't want it operating. Great video!!
If I got another GM half ton the 6.2 has always been the one I’d want. Just wish you could get a larger tank than 24 gallons. Spoiled on the Ram and Ford having larger tank options. Once you have that range it’s hard to go back.
I have a 17 High Country 6.2, love the truck. MPG varies, but usually 20/21. In town sucks, but, highway its decent. I disabled AFM as soon as it left the showroom. Knock on wood no issues and has 80,000 kms
I just bought a 22 6.2l trail boss with a 6.7ft bed I drove it for my business for two days into another state did city and highway driving and it only used 1/2 a tank of fuel and was very impressed with the mileage on 89 octane fuel . I ordered the plug in dfm/afm disabler to protect the lifters and avoid the damage that can be done these are great trucks love that big v8 sound and torque mileage is better than my 3.5l f150 with 33 in tires WELL DONE CHEVROLET nice product
Start saving for when the 10 speed tranny shits the bed. It's not a matter of if but rather when. Stay on top of your ATF and filter, change it often and you may prolong things for a while. Good luck and enjoy your new truck. ☺👍 EDIT: Get rid of the transmission thermostat, unless you live in Siberia or where it's extremely cold VERY OFTEN. Otherwise, trash it.
Would you say the king box is harder to move around in the city or if there a big difference. I want to get a trail boss too and I’m torn between what box
I had a 76 heavy half blazer , 350 4 bolt main motor , dart heads , isky Meagan cam , roller rockers and so forth , 350 turbo trans and NP203 transfer case , locking hubs , 420 HP at rear wheels 398 ft lbs torque, 15 mpg , I'd rather have it than a new $80,000 - $ 100,000 truck , tech is nice but at what cost , my first house was $ 84,000 , I'm 58 by the way
I had a 2023 ZR2 with 6.2L. I averaged 15.3 MPG on 45K. I used 91 octane. I traded for 2024 ZR2 with DuraMax 3.0 diesel and with 4K averaging 21 MPG. I’ll take the 3.0L Duramax anytime over 6.2L
Yes. I have a 2023 Silverado RST with the 6.2L. I drive about 70% hwy and 30% city and I get appx 825km/tank and that works out to appx 11L/100km (21mpg). So yeah, your numbers arent wrong at all. I know people driving V6 tacomas getting worse mileage than my truck lol.
I’ve owned a 2011 f150 with the 1st gen coyote 5.0 for years and was ready to upgrade. I was really looking into the 6.2 Chevy for the power but with DFM issues you would have to pay me instead to get those pickups. Decided to avoid all AFM DFM and got a 6.0 Sierra gasser low miles
2021 Yukon Denali. I lost lifters in both banks within the first 26,000 km. Obviously fixed warranty but it’s still sucked. No problem since and I’m up to 90,000 km. City 20 L for 100 km. But I do punch it off the line. Highway is 13 liters per 100 km. But I’m also doing 130 km an hour. If I take it easy and I’m running the back roads at 80 km an hour. It’s 9.7 L per 100 km. So it’s OK if you don’t jam the skinny pedal the floor. But that’s a little hard to do with the big 6.2. Sure, maybe it would be awesome to get better gas mileage with a smaller engine. But that big v8 sounds so good when you drop the hammer
Super cruise driver monitor infrared lights in steering wheel. Camera picks them up but you don’t see them when you sit at the wheel. This is the hands free tech in GMC and Chevy trucks.
We have a 2017 GMC Yukon Denali with the 6.2 l and 8 sp. When we travel we're usually loaded down pretty good and we get 23-24 mpg on the highway. 18-20 in the city... depending on our lead feet. The worst part of it has been the 8 sp transmission which is trash! Other than that, and the high cost to fix everything, we love this vehicle! I bet with the new 10 sp transmission it's much better!
Here in Australia they are failing a lot lifter failures and bottom end issues,there is a class action ongoing, Ram with the hemi is proving to be reliable .
I think you should give a comparative mpg. If 85 octane is 90% of the price of 93 octane, then multiply the mpg by .9 on the 6.2L since it requires premium fuel.
For a big old pushrod v8 making that much hp and for the displacement its good also drag coefficent of that truck is really good at 0.38 however the direct injection cyclinder deactivation and the 10 speed auto issues will eventually kill it all for what maybe 1 or 2 more mpg.
And now you need to test the 2nd yr 2nd gen 2024 3.0l LZ0 baby Duramax...I've achieved 30.4MPG@70mph on the interstate using cruise control, although the sweet spot seems to be around 65mph, especially while towing...With 305hp and 495ft/lbs torque, it's a beast in it's own right...2024 Silverado 1500 Trail Boss LT... My other truck, a 2020 GMC 3500HD AT4 with the 6.6 L5P Duramax will get 18.5mpg all day long, unless I'm towing my 5th wheel that it...not too bad for an 8400# truck...
1:40 GDI, DFM, Auto StartStop. You can stop there i already don't want it. When i am looking for a large displacement engine for towing or a Diesel, MPG is secondary to torque and reliability.
Diesel engines are 5k to 10k min for something that fails. Turbos are sketch on a good week. What exactly is a good option. Just change oil every 3 to 4k and bam good to go
@@ni99asapimpstastic Depends. New diesels are no bueno. Anything that is pre 07 is probably worth investing in if you want one. 5.9, 7.3 or 6.6 LLY/LBZ, take your pick. Same kind of goes for gas engines. Pre garbage 5.0L or 5.3 / 6.0L are good choices. Older but very torquey options also include 460, 454 and GM 8.1L. Cheap to maintain and will put out well beyond 650 ft.lbs with not much money in the truck vs a new one. If i had to buy a brand new truck right now i would probably just get a 3.5L from Ford, and this is coming from a lifelong GMT lover. 6.7L is also a good engine but has typical Diesel emissions BS all over it. Same goes for the newer 6.6's but newer GM has Dodge syndrome were the truck just falls apart around the engine itself. They truly are torque monsters if you can stomach 5-10k repair bill every 6-7 years. Personally rather pay at the pump and just tow with my 496 which is what i do. The engine cost me about $7000 new and it now sits at 185k zero problems.
I know i have never went to buy a truck and asked the dealer…how about fuel economy? Nope. I wanna know about performance. Will this truck haul ass, pull hard, and be comfy. Don’t give a dam about how much fuel it uses.
Look at that front profile! When the hood is up to your shoulders you're not gliding through the wind. You're pushing through it. Add in a 5,000 lbs curb weight and you're asking that motor to push a brick. Miss the days of reasonable size trucks.
Im happy with my 2017 ltz with the 6.2, got the power i want, and it doesnt have most the junk the new ones have. DFM which is even worse than their AFM system, and now you got the auto stop/start aka the most useless feature ever introduced into automobiles. 2016-2018 also the best looking imo.
Glad to see you brought up the fact that GM “highly” recommends 91 octane or higher fuel. I find it kind of odd that Ford doesn’t recommend the same for the Coyote since it has even slightly higher compression at 12:1. My previous truck had the Coyote in it and there’s no way in Hades I was going to run low octane fuel in something with that high of compression.
Fords knock detection and cam control with the dohc motor is what allows that. I personally still run 91 in mine because it’s noticeably quicker. I would run e85 if it was available near me
Did gm figure out the lifter issue in these later generation ecotechs? I’m looking to upgrade my 15 Silverado with the 5.3 but have not had great reliability. The powertrain looks almost identical to the 14-18 previous generation trucks
I'm not telling you what to buy, but gm was sold in 2009 to Chinese shell companies with the agreement that they not move anything until Obama was out of office. Now, they make almost everything in china. They have other factories as well, but if you look up gm factories in china you'll see. They make almost everything for the trucks in china, then ship it here for north American production. No they haven't fixed the lifer issue. However, ram took the failers on the eco boost and fixed them in their new 3l. I am not a fan of turbo small motors. If I was, that's the one I'd get. The 2019 and up ram 6.4l forged internals. The only motor that does. They shared a bunch with the demon. I just don't like china and Ford is cheap. Everything about it feels cheap. Gm has good interior but... china. I saw a guy who had a fleet of 3500 6.4l hemi pulling hotshots at 16-18k all miles. He was getting 350-450k miles before they needed work. The transmission is bulletproof. I did see cummins is putting out a gas motor for them, I believe, post 25. It has 660 tq in an inline 6.7l. Idk.
Not sure what sonsofliberty is yapping about but I had a 2020 1500 Sierra at4 5.3 traded it at 76,000 miles, never missed a beat. Had a nice exhaust set up on it so I didn’t baby it. It was fuel efficient and ran only 87. I loved the truck, honestly I never stressed about the engine not being reliable. It just always ran strong and smooth with the 10 speed. I towed with it for a while, which did great. Go for it !
When dfm works right it’s nice….but if I had an option to have or not to have, I’d prefer not to have it….id rather have long term dependability over a little gas saving…oh well. Wish they made a plug in ( obd port) to cancel it out on the 6.2 with 10 spd trans….
My brother has the 2023 GMC AT4 6.2 10 speed he said he has to run it at 130km h to get any kind of fuel economy … and that make sense to me because let’s face it when the manufacturers are testing these truck or any car their doing at Interstate speeds which in some states now are 80 mph ..
just bought the new 2025 ram rebel with the hurricane, barely getting 15.5 combined, not pushing it at all, might burn a bit more since brand new and the 1 inch lift with A/T tires but I don't see how the Hemi would have done worse than this, time will tell
Had a 01' Yukon 4wd with the 5.3L and 3.73 gears and no fuel management tricks. I got 22mpg hwy @70mph which tells me that all of those tricks are not doing much to improve mpg. Rather they do more harm than good. First thing I would want to do is a cam and lifter swap and get rid of DFM. Let the engine run like it should.
I keep tossing around the idea of doing an AMF delete and doing a cam swap to make some more power. A decent cam and the tune wakes up a 5.3L nicely. My only concern is the 6L80 isn't exactly the best transmission in the world and I would be worried about breaking it again. My torque converter came apart at 80k miles. And that was with doing the suggested maintenance.
I’m a big fan of your videos, but this isn’t a very fair comparison. You used 91 octane fuel in the 6.2L, but you only used 87 octane in the 5.0L, which is a 12:1 compression engine. I’m pretty sure your mpg numbers would’ve been quite different if you had used 91 octane in all the trucks, especially the 5.0L.
Completely agree. It’s a little bit apples to oranges. But the way I looked at it is most people will be running 87 in the 5L and 91 in the 6.2L so that’s what I ran them with.
Pretty good? That's incredible mileage considering how monstrous that truck is with just short of 500 hp. 20 yrs ago you'd be lucky to get 10mpg. Way to go Chevy.
@@robertyoung8289 Yeah, they announced this year they would stop, but I wished they would have tested these during the last 5 yrs or so. It's really good truck, if my friend didn't have one I would have never known how good they were. I was really impressed, he had the PRO4x (I think?).
My 2017 5.3L half ton gets about 14mpg in the city, 18-19 mpg on the highway, and a16 mpg combined. I'm running a mild lift and 33x11.50 for tires so that probably isn't helping.
I'm along Lake Erie that goes from 0°F(or potentially colder)to 95°F+ so I get all sorts of weather. Snow is the worst as running the 4wd is just painful to look at. The tires definitely don't help but I like the looks. Plus I actually use my truck for truck things. I hauled almost 500kg of powerlifting plates in my bed and got 18 mpg driving through Ohio which has some decent hills. I am running the BFG KO/2 and they definitely improved the ride. Next up is probably an afm delete and a cam upgrade. Thinking about the BTR Truck Norris and the required tuning. Just worried about the 6L80 which isn't exactly known to be a bulletproof transmission.
My friend at work has a dodge challenger hell cat and gets 28 mph on the highway when he drives it easy. Makes no sense I realize that but it is fact. Maybe they is something about his car’s engine that’s somehow different from factory I don’t know. He has tested it multiple times at the pump
Paying more at the pump for premium kills this as an interesting option. Wish you would have used the same octane as other tests as the MPG numbers would be more accurate in comparison to the others. In the future, unless 100% required, please use regular octane.
I disagree. The gas flap specifically states premium fuel required. If you buy a 6.2L you should plan to pay up for the high test fuel. Testing should be done with what the manufacturer recommends. Besides, the test is real world mpg and not $/test run.
@@-_-saucynocap2427 Maybe I miss understood, and thought he said it was optional but recommended. octane will affect MPG which is why I mentioned it. If the manufacturer requires 91, then that's the base test.
@@Chris-ut6eqI have a 2015 with the 6.2L (basically same engine) and you can put regular in it, but the ECU will cut timing and power to keep the engine from grenading itself with the crap fuel. Does suck every time I need to fill it with premium though. Years ago it wouldn't be much of a problem being $0.10 to $0.20 more per gallon, but now in my area, its almost a dollar more a gallon.
@@Chris-ut6eqit's recommended not required. If you're towing with it you should only use premium but if you're just doing normal driving you probably can get away with 87.
@kabloosh699 As he was not towing, would have been good to know the regular octane numbers for the test. He did mention that he thought MPG would be 1less, but adding the premium MPG to the result chart makes it an unfair comparison. Testing details matter because of context. Plus he could comment on regular gas engine performance during the test. Thank you for the information!
I wish GM would quit farting around and get serious....give us a twin turbo L87 with a full hybrid system, like Fords' and Toyotas', squish it between that motor and a 10speed trans, AND let us option to a larger fuel tank...how hard could it be?? 😎 Also using 89 octane fuel doesn't impact fuel mileage, I've been running it for about 400 miles and it hasn't changed. It doesn't have the same power for sure, but mileage is identical...I live in a pretty flat area about 500' above sea level, for what it's worth.
Holy! a twin turbo 6.2L V8 hybrid with that much power you'll be blowing the doors off corvettes. you don't want a hybrid. Ford Powerboost was rated one of the least reliable vehicle in 2023.
@@GettysGaragethe 6.2L has a higher compression ratio than the 5.3L so I think there is some merit to the fact that they ask for premium fuel. It’s not like Toyota saying the Land Cruiser can run on 87 but the LX570 with the same engine needs premium.
the newer 6.2l engines are like playing with dynamite or fire. It is a simple luck of the draw if your engine holds together. There are literally hundreds and hundreds (if not thousands) of these motors coming apart. Look up Cadillac escapade 6.2l problems I have a 2023 silverado crew cab with 6.2l and I didn't even make my first scheduled oil change and the motor self destructed while on the highway at 70mph. It sounded like someone poured a buckets of bolts in the engine and finally jolted the truck to a rough jerking stop. Just imagine towing a trailer in traffic while that happened. It's now going on almost 6 weeks and GM finally delivered a new engine to the dealer, because of all of the engines being back ordered with all the engines being replaced under warranty. I am in the middle of working with GM to get rid of this expensive boat anchor. They (GM) are painfully slow in my case number and they haven't decided if they want to or will do anything other then put in a new junk 6.2l motor with known issues. I have probably purchased well over a dozen new GM vehicles and I was surprised by how little they cared. I finally got tired of the run around and contacted an attorney and provided them with certain Paperwork and contracts. I wouldn't touch a newer 6.2l with a teen foot pole. My families lives and the drivers around me are worth a whole lot more.
You are not alone. I loved this engine. Had the truck for about a week. But until the lifters are addressed officially. I’ll never own one. Which sucks.
The comment about holding 10th gear o the hill is funny. That motor at 1300rpm isn't making all that much torque. That 460lbft is way, way, WAAYY up at 4100rpm. There is near 300lbft at 2500rpm which is down shifting to 6th gear at 90km. The 2.7 I4 if you left it to do it's pull would out work that 6.2 all day long. Let the torque do the work instead of the manipulation of the gearing. This is why I hate gasoline V8s the fool you into thinking they have power(through mechanical manipulation) 420hp@6100rpm is 393lbft. 375hp@5000rpm is 393lbft 400hp@2800rpm is 750lbft 400hp@1900rpm is 1109lbft All have the power but are vastly different in capability. So I'll keep my 500lbft@3000rpm 3.5EB and do more work with less rpm over the NA V8 counterparts, still get better empty mileage. I've seen 8.9L/100km with this 2022 3.5EB. My 2016 was 8.7L/100km London to Ottawa and back more than a few trips. Towing g a 40ft 12k 5th wheel netted me an average of 22.7L/100km, back in July London to North Bay
Wait until you use this truck as a truck( hauling, towing ,etc) , those figures will dramatically decrease. Also you should never go beyond the first click when refueling. You will most definitely have issues with your emissions from your charcoal canister system.
I spent $35K on my 2015 Chevy Silverado and I still get 21 MPG because I do regular maintenance checks, oil changes, and tire rotations. Why would I buy a new truck for nearly $60K? Please explain the logic. Thanks
@@TicklerDude the point is that if you can truly afford a $60k truck then a couple hundred bucks in fuel a year shouldn't even matter. My guess is most are buying more than they can really afford which is why fuel mileage seems to be such a concern.
All these engines and makes seem to have lifter issues, whether the Godzilla, GM, Ram and even the 6.7 diesels. I have a 22 3400 HO Cummins and while I still have about three years and 80k miles of warranty, in the back of my mind I’m still concerned. All these vehicles including g the new flavor of small twin turbo jobs, foreign and domestic, have simply become cost prohibitive to repair outside of warranty.
I’ve got a video line up to talk about the Cummins. A video I never thought I’d be making but they made a mistake putting hydraulic lifters in the 2019+ engines
I was running 91 octane fuel with the 6.2L as recommended so just keep that in mind. Every other engine had 87.
Big premium for premium here in Canada. 91 is a deal breaker for a truck.
This one has to run 93 but 91 is acceptable
@@JoshDurston exactly
I think it comes down to just how you drive and how much you stay off both pedals. I've been able to get 25mpg with my 5.3 on the hwy with the AFM disabled but also not using cruise control.

Hum 11.9 mpg on mine at best in 2wd .
2020 AT4... With factory tires 21 mpg over a tank doing 78. With LT305/50r20 it drops to 17.5.

I wanna see you test a Ford F-150 with the Powerboost 3.5L engine and see what it gets, I have one in my 2023 F-150 King Ranch and love it. 20,000 miles and no problems so far. Ive seen as high as 35 MPG (Granted this was 10 miles averaging about 30 mph with no traffic) but ive averaged 24.7 over the life of the truck. I normally get about 22-23mpg on the highway at 80MPH and around town I normally see anywhere from 25-27mpg, love this truck and can easily do 700 miles in one tank of gas!
Hell yeah! I was iffy on the high speed hwy mileage until I rented one a few months ago for a long family trip out West. Holy shit, I was getting 22.5-23 going 80 mph!

Hi Alex.
Great engine the 6.2 l; but I think the main headache "DFM".
And the 5.3 l; it's enough and fabulous fuel efficiency, especially when towing is not frequent.
I prefer the 6.6 Duramax to hard work. 😮
Big HUG! 😮
I can’t wait to eventually get the Lz0 on these towing and fuel economy tests. I work not be shocked if it ends up on top. It’s my favorite engine I’ve Driven in these half ton trucks
I test drove one before the 6.2 test drive and coming from a Hemi Rebel the acceleration on the 3.0 was abysmal. I really wanted to like that engine and to be honest I wish I had gone that route.
A throttle tuner would help the sluggish acceleration a bunch!
@@mrcarpentersc it’s a diesel. If you’re looking for off the like acceleration the engine wasnt meant for you in the first place.
That fuel octane note in the middle of the video is hugely important. Your cost per mile on a lot of gas 2500 trucks all of a sudden become alot more favorable when comparing say the Chevy 6.6 gasser 2500 vs a 6.2 1500 with a max tow package...arguably two trucks one might buy for a similar sized trailer/use case.
as usual, your video is very informative . thanks
DFM is literally cancer to these engines. If you keep it long enough it has a 100% failure rate to where you’re going to be replacing rings, pistons, lifters, camshafts, and the bill will be between $4000 and $5000. How do I know? It happened to me.
Any fuel savings you have over the life of the engine go right out the window.
Did they put in the same lifters to allow dfm to still work (and eventually fail again) or did you change to solid lifters and delete dfm?
I had the same truck. I ended up trading it in on a ‘24 2500 Duramax. I always felt that at some point those lifters were going to go south.
I agree. Dfm is absolute garbage. I have afm on my company tahoe and there ain’t any fuel savings.
I had this 6.2 for about a week and actually really really liked it. More than I thought I would. But, until the lifter issues are addressed concretely. I’ll never own one unfortunately.
@TheGettyAdventures Same. Its a ok engine but I doubt ill ever own it. Would love to do the tow test with the 502 big block!
Love your videos. Are you going to swing in either of the Hemi’s on these new tests?
Yeah id love to see both hemis
My 2024 6.2 Trailboss has a 10k fuel average of 17.4 mpgs. Factor in that i tow a 4-5000# trailer a few times a week so a rough guess that 2500- 3000 of those miles were towing.
I'm totally happy with the mpg's and i drive very sensible most of the time while having fun off road and some spirited acceleration blasts. Sure i hate the DFM because of the poor reliability but I'll say i like the start/ stop because i can hit the switch to turn the system off when i don't want it operating.
Great video!!
If I got another GM half ton the 6.2 has always been the one I’d want. Just wish you could get a larger tank than 24 gallons. Spoiled on the Ram and Ford having larger tank options. Once you have that range it’s hard to go back.
I have a 17 High Country 6.2, love the truck. MPG varies, but usually 20/21. In town sucks, but, highway its decent. I disabled AFM as soon as it left the showroom. Knock on wood no issues and has 80,000 kms
Probably a smart move tuning out the DFM. For the extra 1/2 mpg better seems not worth it.
I just bought a 22 6.2l trail boss with a 6.7ft bed I drove it for my business for two days into another state did city and highway driving and it only used 1/2 a tank of fuel and was very impressed with the mileage on 89 octane fuel . I ordered the plug in dfm/afm disabler to protect the lifters and avoid the damage that can be done these are great trucks love that big v8 sound and torque mileage is better than my 3.5l f150 with 33 in tires WELL DONE CHEVROLET nice product
Start saving for when the 10 speed tranny shits the bed.
It's not a matter of if but rather when.
Stay on top of your ATF and filter, change it often and you may prolong things for a while.
Good luck and enjoy your new truck. ☺👍
EDIT: Get rid of the transmission thermostat, unless you live in Siberia or where it's extremely cold VERY OFTEN.
Otherwise, trash it.
Would you say the king box is harder to move around in the city or if there a big difference. I want to get a trail boss too and I’m torn between what box
I had a 76 heavy half blazer , 350 4 bolt main motor , dart heads , isky Meagan cam , roller rockers and so forth , 350 turbo trans and NP203 transfer case , locking hubs , 420 HP at rear wheels 398 ft lbs torque, 15 mpg , I'd rather have it than a new $80,000 - $ 100,000 truck , tech is nice but at what cost , my first house was $ 84,000 , I'm 58 by the way
Sounds Nice....My favorite ride...K5/Jimmy had as my 1st ride, want another, but they are pricy now...
Sold mine due to a divorce, the second mistake of my life
I had a 2023 ZR2 with 6.2L. I averaged 15.3 MPG on 45K. I used 91 octane. I traded for 2024 ZR2 with DuraMax 3.0 diesel and with 4K averaging 21 MPG. I’ll take the 3.0L Duramax anytime over 6.2L
you should test the silverado 1500 with the 3.0 and see how it does
Yes. I have a 2023 Silverado RST with the 6.2L. I drive about 70% hwy and 30% city and I get appx 825km/tank and that works out to appx 11L/100km (21mpg). So yeah, your numbers arent wrong at all. I know people driving V6 tacomas getting worse mileage than my truck lol.
For some reason, I cannot get past 15 miles per gallon. I have a 2022 Silverado RST with the ALC package.
How did I miss this one 😱
I’ve owned a 2011 f150 with the 1st gen coyote 5.0 for years and was ready to upgrade. I was really looking into the 6.2 Chevy for the power but with DFM issues you would have to pay me instead to get those pickups.
Decided to avoid all AFM DFM and got a 6.0 Sierra gasser low miles
2021 Yukon Denali. I lost lifters in both banks within the first 26,000 km. Obviously fixed warranty but it’s still sucked. No problem since and I’m up to 90,000 km. City 20 L for 100 km. But I do punch it off the line. Highway is 13 liters per 100 km. But I’m also doing 130 km an hour. If I take it easy and I’m running the back roads at 80 km an hour. It’s 9.7 L per 100 km.
So it’s OK if you don’t jam the skinny pedal the floor. But that’s a little hard to do with the big 6.2.
Sure, maybe it would be awesome to get better gas mileage with a smaller engine. But that big v8 sounds so good when you drop the hammer
I was getting the same results on my 2023 ZR2.
That v8 sounds good
What is flashing at the top side of the steering wheel?
Super cruise driver monitor infrared lights in steering wheel. Camera picks them up but you don’t see them when you sit at the wheel. This is the hands free tech in GMC and Chevy trucks.
I don’t see the 5.7 ram on those comparison tests. Would be interested to see that one.
I can get 22 hwy on a 19 ram 1500 with the 5.7 and 16 city.
We have a 2017 GMC Yukon Denali with the 6.2 l and 8 sp. When we travel we're usually loaded down pretty good and we get 23-24 mpg on the highway. 18-20 in the city... depending on our lead feet. The worst part of it has been the 8 sp transmission which is trash! Other than that, and the high cost to fix everything, we love this vehicle! I bet with the new 10 sp transmission it's much better!
lol the 8 speed is not the greatest but still I was surprised how efficient the 6.2L was.
@@GettysGarage the 6.2 has to be better with the 10 Speed..... isn't it?
Can you deactivate the DFM on these trucks?
2023 GMC Sierra Denali 6.2 but with 6-6 box. Average 17.5 MPG running #93 within 22k miles range, while highest 21.7 mpg for a tank of gas.
Here in Australia they are failing a lot lifter failures and bottom end issues,there is a class action ongoing, Ram with the hemi is proving to be reliable .
Yes unfortunately we are seeing a lot of lifter issues here as well.
Are we going to see the 5.7 ram in this test and the towing test?
I think you should give a comparative mpg. If 85 octane is 90% of the price of 93 octane, then multiply the mpg by .9 on the 6.2L since it requires premium fuel.
For a big old pushrod v8 making that much hp and for the displacement its good also drag coefficent of that truck is really good at 0.38 however the direct injection cyclinder deactivation and the 10 speed auto issues will eventually kill it all for what maybe 1 or 2 more mpg.
Please test/revisit the LZ0 engine. I’m loving my 2024 LZ0 AT4.
And now you need to test the 2nd yr 2nd gen 2024 3.0l LZ0 baby Duramax...I've achieved 30.4MPG@70mph on the interstate using cruise control, although the sweet spot seems to be around 65mph, especially while towing...With 305hp and 495ft/lbs torque, it's a beast in it's own right...2024 Silverado 1500 Trail Boss LT...
My other truck, a 2020 GMC 3500HD AT4 with the 6.6 L5P Duramax will get 18.5mpg all day long, unless I'm towing my 5th wheel that it...not too bad for an 8400# truck...

GDI, DFM, Auto StartStop.
You can stop there i already don't want it. When i am looking for a large displacement engine for towing or a Diesel, MPG is secondary to torque and reliability.
Diesel engines are 5k to 10k min for something that fails. Turbos are sketch on a good week. What exactly is a good option. Just change oil every 3 to 4k and bam good to go
All the newer motors are GDI and auto stop. The 5.0 liter Coyote has cylinder deactivation too.
@@ni99asapimpstastic Depends. New diesels are no bueno. Anything that is pre 07 is probably worth investing in if you want one. 5.9, 7.3 or 6.6 LLY/LBZ, take your pick.
Same kind of goes for gas engines. Pre garbage 5.0L or 5.3 / 6.0L are good choices. Older but very torquey options also include 460, 454 and GM 8.1L. Cheap to maintain and will put out well beyond 650 ft.lbs with not much money in the truck vs a new one.
If i had to buy a brand new truck right now i would probably just get a 3.5L from Ford, and this is coming from a lifelong GMT lover. 6.7L is also a good engine but has typical Diesel emissions BS all over it. Same goes for the newer 6.6's but newer GM has Dodge syndrome were the truck just falls apart around the engine itself. They truly are torque monsters if you can stomach 5-10k repair bill every 6-7 years.
Personally rather pay at the pump and just tow with my 496 which is what i do. The engine cost me about $7000 new and it now sits at 185k zero problems.
I know i have never went to buy a truck and asked the dealer…how about fuel economy? Nope.
I wanna know about performance. Will this truck haul ass, pull hard, and be comfy. Don’t give a dam about how much fuel it uses.
Can you get an older 5.3 to test? Like a 2014-ish?
Because I am truck shopping and a 2022 is too rich for me at the moment!
A black vehicle is always dirty. I’m getting 17 in my satin steel metallic extended cab
If I put half 93 and half 87 in the tank, I should get about 90 on average. That's good enough for me!
thx alex love your content! once gain , frome a nother canadian alex!
When are you going to test the 3.0 Duramax on the mpg/towing loop? It will run circles for fuel economy over all of those trucks in all aspects.
Can you do the same test with the 3.0L duramax? Thanks
I get 16 on my 98 silverado, but I love my truck
They don’t make them like they used to. Those GMT 400 trucks are worth their weight in gold
How much was it to fill a tank
Look at that front profile! When the hood is up to your shoulders you're not gliding through the wind. You're pushing through it. Add in a 5,000 lbs curb weight and you're asking that motor to push a brick. Miss the days of reasonable size trucks.
I would be curious to see where the 5.7 Hemi fits into the fuel economy comparison
At the back of the pack
I want to get it on the loop!
@@GettysGarage that would be great.,
Are there good options for tuning this ecm so that is doesn’t use dfm….or do you have to do a full delete/swap of lifter and cams, etc…?
@thegettyadventures any chance you will be able to get your hands on the new Toyota 2.4 iforce engine?
Another awesome video! Some killer shots in here too. Also you are hot 🔥
Im happy with my 2017 ltz with the 6.2, got the power i want, and it doesnt have most the junk the new ones have. DFM which is even worse than their AFM system, and now you got the auto stop/start aka the most useless feature ever introduced into automobiles. 2016-2018 also the best looking imo.
Can you do the same MPG test with ram….hemi vs new i6 turbo. Then finally compared to the rest of your list.
man we're waiting for 3.0 duramax!! Just know about it!
Hello have you tested the LZO 3.0 straight 6 diesel motor’s?
Glad to see you brought up the fact that GM “highly” recommends 91 octane or higher fuel. I find it kind of odd that Ford doesn’t recommend the same for the Coyote since it has even slightly higher compression at 12:1. My previous truck had the Coyote in it and there’s no way in Hades I was going to run low octane fuel in something with that high of compression.
Fords knock detection and cam control with the dohc motor is what allows that. I personally still run 91 in mine because it’s noticeably quicker. I would run e85 if it was available near me
Did gm figure out the lifter issue in these later generation ecotechs? I’m looking to upgrade my 15 Silverado with the 5.3 but have not had great reliability. The powertrain looks almost identical to the 14-18 previous generation trucks
I'm not telling you what to buy, but gm was sold in 2009 to Chinese shell companies with the agreement that they not move anything until Obama was out of office. Now, they make almost everything in china. They have other factories as well, but if you look up gm factories in china you'll see. They make almost everything for the trucks in china, then ship it here for north American production. No they haven't fixed the lifer issue. However, ram took the failers on the eco boost and fixed them in their new 3l. I am not a fan of turbo small motors. If I was, that's the one I'd get. The 2019 and up ram 6.4l forged internals. The only motor that does. They shared a bunch with the demon. I just don't like china and Ford is cheap. Everything about it feels cheap. Gm has good interior but... china. I saw a guy who had a fleet of 3500 6.4l hemi pulling hotshots at 16-18k all miles. He was getting 350-450k miles before they needed work. The transmission is bulletproof. I did see cummins is putting out a gas motor for them, I believe, post 25. It has 660 tq in an inline 6.7l. Idk.
Not sure what sonsofliberty is yapping about but I had a 2020 1500 Sierra at4 5.3 traded it at 76,000 miles, never missed a beat. Had a nice exhaust set up on it so I didn’t baby it. It was fuel efficient and ran only 87. I loved the truck, honestly I never stressed about the engine not being reliable. It just always ran strong and smooth with the 10 speed. I towed with it for a while, which did great. Go for it !
Been many fail before the first oil change. I’d run away from any gm.
@@freedomisntfree_44 all brands have issues.
@@nicholaspacheco4554 especially gm
I have a 21 rst with a 6.2 and no dfm or afm. I get about 20mpg city and 25 on the highway.
When dfm works right it’s nice….but if I had an option to have or not to have, I’d prefer not to have it….id rather have long term dependability over a little gas saving…oh well. Wish they made a plug in ( obd port) to cancel it out on the 6.2 with 10 spd trans….
Very much agreed. I would suspect the 6.2 (and the 5.3) would be still efficient engines without it.
I'm a driver on a 16 Yukon Denali and can get 23hwy and 19 mix and 16 city on 87 octane.
My brother has the 2023 GMC AT4 6.2 10 speed he said he has to run it at 130km h to get any kind of fuel economy … and that make sense to me because let’s face it when the manufacturers are testing these truck or any car their doing at Interstate speeds which in some states now are 80 mph ..
You should do the 3.0 duramax next
I would of got the 6.2 if you could turn off the AFM because the lifters so I got the 3.0 and love it
Would you add the duramax LZO to your testing?
Very much hoping to get my hands on one!
Which would you prefer to daily, a Whipple supercharged 5.3L or a stock 6.2L? Sincerely, a guy with a 5.3 and buyers remorse.
With my 5.0 Coyote, the best gas mileage has been achieved at speeds 65 or below.
I like my 22 5.0 and on a 2100 mile trip average 24.5. I do have 3.31 gears. ( 36 gallon fuel tank makes it nice too).
The 5L is a fantastic engine. I honestly thought it would be more efficient on my loop but It’s still the first engine I’d buy in a 1500 at this point
just bought the new 2025 ram rebel with the hurricane, barely getting 15.5 combined, not pushing it at all, might burn a bit more since brand new and the 1 inch lift with A/T tires but I don't see how the Hemi would have done worse than this, time will tell
Do you use premium in all of the engines or just the 6.2L?
Just the 6.2L
Alex why are you using mpg's and mph? Here in Atlantic Canada we don't use either.What's up with that?
We do…. ;)

Had a 01' Yukon 4wd with the 5.3L and 3.73 gears and no fuel management tricks. I got 22mpg hwy @70mph which tells me that all of those tricks are not doing much to improve mpg. Rather they do more harm than good. First thing I would want to do is a cam and lifter swap and get rid of DFM. Let the engine run like it should.
I have the Ford 3.5 ecoboost, I'm coming to the conclusion that it is more about emissions than economy?
I keep tossing around the idea of doing an AMF delete and doing a cam swap to make some more power. A decent cam and the tune wakes up a 5.3L nicely. My only concern is the 6L80 isn't exactly the best transmission in the world and I would be worried about breaking it again. My torque converter came apart at 80k miles. And that was with doing the suggested maintenance.
@@nevillemcnaughton6306 Yeah it's more about selling more trucks and more car parts.
@@bmstylee I would think if you stay with a relatively decent RV type cam you should be ok.
@@nevillemcnaughton6306 I think you're exactly right
I’m a big fan of your videos, but this isn’t a very fair comparison. You used 91 octane fuel in the 6.2L, but you only used 87 octane in the 5.0L, which is a 12:1 compression engine. I’m pretty sure your mpg numbers would’ve been quite different if you had used 91 octane in all the trucks, especially the 5.0L.
I'm pretty sure his numbers would be different if he ever had to turn the AC on or sit in bumper to bumper traffic.
Completely agree. It’s a little bit apples to oranges. But the way I looked at it is most people will be running 87 in the 5L and 91 in the 6.2L so that’s what I ran them with.
I wonder why no one ever includes Nissan Titans in these tests? (btw I don't own one)
They are not producing anymore so why bother. To bad. They have alot to offer.
Pretty good? That's incredible mileage considering how monstrous that truck is with just short of 500 hp. 20 yrs ago you'd be lucky to get 10mpg. Way to go Chevy.
@@robertyoung8289 Yeah, they announced this year they would stop, but I wished they would have tested these during the last 5 yrs or so. It's really good truck, if my friend didn't have one I would have never known how good they were. I was really impressed, he had the PRO4x (I think?).
@@flyonawall6521 I have the new Frontier. I'm shocked what a well built truck it is. I'm sure the Titans no exception.
Last yr is 24. Test one on the loop and let's see how it does for funzies
My 2017 5.3L half ton gets about 14mpg in the city, 18-19 mpg on the highway, and a16 mpg combined. I'm running a mild lift and 33x11.50 for tires so that probably isn't helping.
And you probably live in the States where we have to blast AC for survival and we have bad traffic. I've never been out of the teens combined.
Those tires are probably sucking back that fuel. But I bet she looks good 👍
I'm along Lake Erie that goes from 0°F(or potentially colder)to 95°F+ so I get all sorts of weather. Snow is the worst as running the 4wd is just painful to look at. The tires definitely don't help but I like the looks. Plus I actually use my truck for truck things. I hauled almost 500kg of powerlifting plates in my bed and got 18 mpg driving through Ohio which has some decent hills. I am running the BFG KO/2 and they definitely improved the ride. Next up is probably an afm delete and a cam upgrade. Thinking about the BTR Truck Norris and the required tuning. Just worried about the 6L80 which isn't exactly known to be a bulletproof transmission.
We have a 2018 tahoe and 2023 sierra both with the 6.2. The wife managed to get 8.9 l/100km and i got 8.5 l/100km with th3 sierra.
That’s actually wild. I had this truck for a week and was surprised how efficient the truck was when it was unloaded
It's an at4 so 2' lift and all terrain tires. We're in Alberta close to the rockys so not flat terrain either.

How about testing midsize trucks.
I have a ford ranger coming to me soon!
I have almost always been able to get better MPG's in a Chevy over a comparable Ford.
Did I miss the gear ratio? I watched it twice. Are you running 3.23:1 or 3.42:1?
I believe in the last video he said 3.23.
Just go with the inline 3L Diesel. 30MPG and it accelerates faster than the 6.2L gas.
My friend at work has a dodge challenger hell cat and gets 28 mph on the highway when he drives it easy. Makes no sense I realize that but it is fact. Maybe they is something about his car’s engine that’s somehow different from factory I don’t know. He has tested it multiple times at the pump
I would imagine it’s that the big V8 can just roll along on top gear without working hard. But 28 mpg is wild out of 700hp engine
Eh BS
Paying more at the pump for premium kills this as an interesting option. Wish you would have used the same octane as other tests as the MPG numbers would be more accurate in comparison to the others. In the future, unless 100% required, please use regular octane.
I disagree. The gas flap specifically states premium fuel required. If you buy a 6.2L you should plan to pay up for the high test fuel. Testing should be done with what the manufacturer recommends. Besides, the test is real world mpg and not $/test run.
@@-_-saucynocap2427 Maybe I miss understood, and thought he said it was optional but recommended.
octane will affect MPG which is why I mentioned it.
If the manufacturer requires 91, then that's the base test.
@@Chris-ut6eqI have a 2015 with the 6.2L (basically same engine) and you can put regular in it, but the ECU will cut timing and power to keep the engine from grenading itself with the crap fuel. Does suck every time I need to fill it with premium though. Years ago it wouldn't be much of a problem being $0.10 to $0.20 more per gallon, but now in my area, its almost a dollar more a gallon.
@@Chris-ut6eqit's recommended not required.
If you're towing with it you should only use premium but if you're just doing normal driving you probably can get away with 87.
@kabloosh699 As he was not towing, would have been good to know the regular octane numbers for the test. He did mention that he thought MPG would be 1less, but adding the premium MPG to the result chart makes it an unfair comparison. Testing details matter because of context. Plus he could comment on regular gas engine performance during the test.
Thank you for the information!
I get 19 with mine on 91 octane and 17 on 87.
Wonder why they get such bad fuel mileage pulling that enclosed trailer.My 2.7 gets around 7-8 pulling my 33ft bumpers pull around 7500 pounds
I wish GM would quit farting around and get serious....give us a twin turbo L87 with a full hybrid system, like Fords' and Toyotas', squish it between that motor and a 10speed trans, AND let us option to a larger fuel tank...how hard could it be?? 😎 Also using 89 octane fuel doesn't impact fuel mileage, I've been running it for about 400 miles and it hasn't changed. It doesn't have the same power for sure, but mileage is identical...I live in a pretty flat area about 500' above sea level, for what it's worth.
Holy! a twin turbo 6.2L V8 hybrid with that much power you'll be blowing the doors off corvettes. you don't want a hybrid. Ford Powerboost was rated one of the least reliable vehicle in 2023.
Premium fuel required...
So is the Nissan Titan. So is a lot of things now. I think the Ram wth HO hurricane too.
Not totally true. You just won't get full performance.
Premium required on 6.2 and hurricane HO. Recommended on 'some' 9f the others.
Technically no… BUT realistically yes it needs and should be run on premium
@@GettysGaragethe 6.2L has a higher compression ratio than the 5.3L so I think there is some merit to the fact that they ask for premium fuel.
It’s not like Toyota saying the Land Cruiser can run on 87 but the LX570 with the same engine needs premium.
the newer 6.2l engines are like playing with dynamite or fire. It is a simple luck of the draw if your engine holds together. There are literally hundreds and hundreds (if not thousands) of these motors coming apart. Look up Cadillac escapade 6.2l problems I have a 2023 silverado crew cab with 6.2l and I didn't even make my first scheduled oil change and the motor self destructed while on the highway at 70mph. It sounded like someone poured a buckets of bolts in the engine and finally jolted the truck to a rough jerking stop. Just imagine towing a trailer in traffic while that happened. It's now going on almost 6 weeks and GM finally delivered a new engine to the dealer, because of all of the engines being back ordered with all the engines being replaced under warranty. I am in the middle of working with GM to get rid of this expensive boat anchor. They (GM) are painfully slow in my case number and they haven't decided if they want to or will do anything other then put in a new junk 6.2l motor with known issues.
I have probably purchased well over a dozen new GM vehicles and I was surprised by how little they cared.
I finally got tired of the run around and contacted an attorney and provided them with certain Paperwork and contracts.
I wouldn't touch a newer 6.2l with a teen foot pole. My families lives and the drivers around me are worth a whole lot more.
That fuel economy means jack squat when your paying an extra $1.20-$1.50 a gallon. Mpg may be ok....but economically it's on the bottom of the pile.
I wanted the 6.2 but the lifters scare me
You are not alone. I loved this engine. Had the truck for about a week. But until the lifters are addressed officially. I’ll never own one. Which sucks.
When i take my 6.2 down two lane 55mph roads the mileage goes WAY up, into the upper 20s easily.
The comment about holding 10th gear o the hill is funny. That motor at 1300rpm isn't making all that much torque. That 460lbft is way, way, WAAYY up at 4100rpm. There is near 300lbft at 2500rpm which is down shifting to 6th gear at 90km. The 2.7 I4 if you left it to do it's pull would out work that 6.2 all day long. Let the torque do the work instead of the manipulation of the gearing. This is why I hate gasoline V8s the fool you into thinking they have power(through mechanical manipulation)
420hp@6100rpm is 393lbft. 375hp@5000rpm is 393lbft
400hp@2800rpm is 750lbft
400hp@1900rpm is 1109lbft
All have the power but are vastly different in capability. So I'll keep my 500lbft@3000rpm 3.5EB and do more work with less rpm over the NA V8 counterparts, still get better empty mileage. I've seen 8.9L/100km with this 2022 3.5EB. My 2016 was 8.7L/100km London to Ottawa and back more than a few trips. Towing g a 40ft 12k 5th wheel netted me an average of 22.7L/100km, back in July London to North Bay
Coyote gas doesn’t matter when it sounds so good.
Where's the Nissan Frontier? My 2024 gets better mpg than all the trucks listed when driving at highway speeds.
Ha haha, ok son. Go play with your toys.
The midsize trucks are coming good sir
Wait until you use this truck as a truck( hauling, towing ,etc) , those figures will dramatically decrease. Also you should never go beyond the first click when refueling. You will most definitely have issues with your emissions from your charcoal canister system.
I towed my 8,000lbs trailer with the 6.2. Second most efficient truck. Shocked me. The turbo engines suck back fuel much heavier with a load on them
i would never buy something with start stop or fuel management just wears out the engine faster
I have 23 Chevy 22.8 5.3
Volvo Trucks in Sweden makes a V8 diesel actually if you want to test a real V8 for a change😊
Interesting. I wonder why they run a V8 not an inline-6
If you have $60k+ to spend on a truck why is fuel economy even a concern?
Intelligence 😂
Because you spent $60k on a truck 😅
I spent $35K on my 2015 Chevy Silverado and I still get 21 MPG because I do regular maintenance checks, oil changes, and tire rotations. Why would I buy a new truck for nearly $60K? Please explain the logic. Thanks
@@TicklerDude the point is that if you can truly afford a $60k truck then a couple hundred bucks in fuel a year shouldn't even matter. My guess is most are buying more than they can really afford which is why fuel mileage seems to be such a concern.
@@TH-camuser1aacame here to say this! 😂😂
I told you 10 months ago that a 5.3 w a ten speed will get the best mpg of any V8 you test. You were hung up on Ford.
well the results don't lie. Thats why I do these videos lol
Auto stop/start listed as a benefit 🤦♂🤦♂🤦♂
Can you confirm that those GM V8s are push rod motors.
They are
Can confirm
All these engines and makes seem to have lifter issues, whether the Godzilla, GM, Ram and even the 6.7 diesels.
I have a 22 3400 HO Cummins and while I still have about three years and 80k miles of warranty, in the back of my mind I’m still concerned.
All these vehicles including g the new flavor of small twin turbo jobs, foreign and domestic, have simply become cost prohibitive to repair outside of warranty.
The small twin turbo jobs are not that expensive to repair though.
@@Jay-me7gw cab off to get at them on the Ram, Tacoma and Tundra. Lotsa hours.
I’ve got a video line up to talk about the Cummins. A video I never thought I’d be making but they made a mistake putting hydraulic lifters in the 2019+ engines
@@GettysGarage look forward to it. Also, as a mechanic, can you spend time speaking to fuel supplements? Snake oil or not? I use power service.
I can hear that ticking in your video! Time for lifters and a new cam!
lol you hear nothing 😅
You lost me when you said premium fuel ⛽️. Do gm see the price of gas ⛽️
