I have the same exact trailer hitch that you used on this trip and I’ve used it with my last three trucks now and it is really nice to know your tongue weight and be able to adjust the height of your load depending on the truck or trailer you are using.

Tim on this particular trip did you happen to check if it burned oil and if so how much . Iam just wondering . Thx Roy

[@mitchellbarber6971]

You nailed all the reasons why I purchased a 2023GMC AT4 with the 3L diesel. I wanted a reliable, fuel efficient truck with good power. I wanted a smooth and quiet ride. I did not want cylinder deactivation or other fancy fuel saving measures. I am extremely happy with my choice and my around town fuel economy this spring is almost 30 mpg!

[@NMTRUCKER]

Tim, thanks for addressing a lot of the “issues” that some folks have with diesels. I bought a 2023 GMC SIERRA with the LZ0 about 4 months ago but I didn’t tell the wife it was going to have a turbo diesel engine. When I brought it home she kinda gave me the, a diesel, look. After four months of ownership we were driving home and she turned to me and said I really love this truck! Need I say anymore?

[@paleh0rse]

​@@thedude7315 - If diesel is only 15-25% more expensive than regular gas - currently 50 to 70 cent difference in most states right now - the mpg only needs to be that same low percentage to break even. At an average of 28 or 30 mpg, there are only a few full size 4WD trucks using gas that would even come close to breaking even at 22-24 mpg.

[@Lefishn]

​@paleh0rse and for people like me in Canada that diesel is cheaper than gas it's a huge savings

I own a 2021 GMC Sierra AT4 with the Duramax. I think this is the best drivetrain for a 1/2 pickup I’ve ever owned. I am sure the LZ0 is even more refined. I’ll be keeping this truck for a long time, and if I had to replace it, I’d still pick the diesel. Great video! Thanks.

I drove to the middle of NY from VA in April and got 32.9mpg after 256 miles of highway driving. My best 50 mile stretch was 42mpg. These engines are crazy efficient. They should be offered in large luxury sedans. I’d buy one of those too.

[@gsguy9359]

Tim, your video is 100% accurate and I have the same comments and experience as you. I have a 2020 Chev High Country with an LM2 which I purchased with 13000 Kms, and now have 63,000 Kms. This truck continues to impress me every time I get in it. The so called hassles the gas guys continue to throw in our face is coming completely from lack of understanding this new diesel setup. This truck, engine, transmission and emissions package is second to none in my opinion. One thing to note, as well is , this truck has one of the lowest emissions of most vehicles on the road(lower carbon footprint). Diesel fuel requires a less refining process (lower carbon footprint), so coincidentally this truck package is also one of the most environmentally friendly vehicles on the road!! Happy trails everyone!!

I’m 2 weeks into my 2023 1500 AT4 3.0 and love it. I loved my 2013 Ecoboost for towing but this is a whole new level. 28.6 mpg driving over 2 passes home from Seattle. Very happy with my choice.

[@robertsanborn1056]

I'm planning on buying A Chevy Silverado with the 3.0 Duramax engine. A few weeks ago, I took for a test drive and was very impressed with the truck.

[@PygmySurfer]

I wasn’t too concerned with the cost of diesel fuel, I was looking for more range while towing. Haven’t had a chance to test that out yet (1 month til our first camping trip), but so far I’m loving the LZO. 1000 kms/tank is awesome. Diesel currently being 15c/L less than 87 octane gas here in Nova Scotia is an added bonus.

[@JesseLJohnson]

Diesel was always cheaper here in the US too in the past. Here where I live on the SC coast its about $3.90-$3.99 a gallon for diesel. Gas prices shot right up the last month or so but diesel didn't seem to change for some reason but gas is about $3.50 for 87. Last gas I got at Costco for my Suburban was $2.99 a few weeks ago but seems its went up nearly $0.50 everywhere since. I just bought a brand new Denali Ultimate last week with the LZ0. I haven't drove it enough to even think about filling up only has 113 miles on it so far might have ran through 1/8th tank so far and its been basically all city driving

[@PygmySurfer]

@@JesseLJohnson Gas has been going up here lately, as well, while diesel has been falling. I've had my truck since November, and I only have around 4000 kms on it :) camping season is starting soon, though, we'll finally add some miles then.

[@omardelgado5167]

Bring DEF! I'm not sure how far your going but carry at least 1 bottle with you.

[@chucknSC]

Your analysis is correct. Diesel fuel has about 30 percent more energy content per gallon. That means that the same fuel tank size gets you about 30 percent more range, 30 percent fewer stops etc. Diesel is also a safer fuel than gasoline and thus allows us to have additional aftermarket fuel tanks which are safer and also increase range. My diesel can go about 1400 miles (700 towing) between fill ups but more useful is the ability to get from one campground to the next without needing to pull our fifth wheel camper thru a fuel station. And to boot, you didn’t give up the power you need to tow ( actually have more), and diesels typically tow hills without all the downshifting of gas engines which makes for a much more relaxed and quiet tow. These are many of the reasons why diesel truck owners are diesel truck owners. Sure we could use a gas power plant but most of us won’t after running diesels for towing. I have never been aware when My 2022 Duramax does/did a regen in its first 7500 miles. I know it it did but I didn’t know it.

[@LPM84.]

Thanks for all the information. Your views and videos on this 3.0L diesel truck made it much easier to purchase my 24 GMC SLT 3.0 diesel.

[@chrislowe4310]

Totally agree with you Tim, I have had two 5.3' in a 14 Silverado and a 17 Sierra. When it came to getting a 23 I hemmed and hawed between the 3.0 and the 5.3, even momentarily considered the 2.7. I had heard the horror stories about the 3.0 but I have a diesel Kioti tractor so not new to a diesel. In the end I went with the LZ0 and have no regrets at all. The only issue was with the block heater plugged in when it wasn't cold enough which caused the fan issue that you had. Let the truck sit for 6 hours and it was fine. Don't know why more people don't consider the 3.0 the torque is impressive, as is the fuel economy and quiet to boot. As for def I topped it up 2100 kms and used about a gallon and a half. The oil level is the same as when it was delivered and I check it weekly being a new engine. In Canadian values I average about 8.5 lt/100 kms. Have had as low as 7.1 at a steady 110 kms per hour, agree it should be in more GM vehicles, probably the best powertrain that I have owned in a half ton truck.

[@kaivonmortazavi8656]

Tim, Thanks for this video. While the towing weight was not significant, going up and down real mountain passes was very informative. I agree, given the significant reduction in gap between diesel and regular unleaded prices, this particular diesel engine make a lot of sense now - even after you take into consideration DEF (which is such a no issue it blows my mind how people can so lost in the weeds), and higher oil change costs. Math is Math! In my area diesel is now very close to the price of regular unleaded - so when you take into consideration the mpg differences, this engine is a clear winner in every category including financial over the 5.3L (even with the higher initial engine cost if you keep the truck for a few years…..math is math). Given that the 5.3 lacks the torque of this engine, then you really need to compare tis to the 6.2L engine and then it really blows the 6.2L away financially. Nice truck.

[@jamesstout1865]

Math makes it very close to a wash at present prices, adding DEF and additional cost of oil changes. ( I figured between .155 and .16 per mile with both the 3.0 and 5.3 gas). The big advantage of the Diesel is the torque and calmness of the powertrain towing. It is very pleasant experience to tow with a diesel. Also pretty cool to get the big numbers on the dash while doing longer trips not towing. I Would love to play with one of these but will probably stay with my 6.6's

[@davidjondoh8671]

Just bought the '23 High Country 2500 miles ago and absolutely love it! Never owned a diesel in my life till now. The torque is incredible, power up the wazoo. Very nice truck!

[@BenDinger]

I really appreciate this series. I currently own and love a 2020 F-150 with the 3.5 EcoBoost, it's given me 56,000 trouble-free miles in 2 years and 9 months. That said if I bought a new truck today I'd be hard pressed not to get a Silverado with the Duramax. I think they've fixed all the potential issues with the previous gen and you nailed it - this is quiet, smooth efficient power. Just a total knock out of a drivetrain.

[@gopnick]

I had a 3.5 EB. It was the last truck I truly loved until this 3.0 Duramax. They have some similarities in terms of use case.

[@caseyjennison2911]

Great review Tim! I have owned an 18' 2500 and 22' AT4 both with the dura max and loved both but decided ai don't tow 18500 lbs so traded in for a 22' GMC Sierra SLT with the 3.0 diesel. I love it! I think many peoples' concerns around regeneration are that it has caused a host of expensive powertrain repairs not covered under some of the manufacturers warranty and many people believe it to be caused by not allowing the regeneration cycle to complete before shutting off the engine.

[@davidroman1654]

Owned a 2021 RST, Z71, Texas Addition with the 3.0. One long camping trip last summer and averaged 13+ while towing a 32' TT that has a dry weight of 6,800. Live in West Texas and trip was to Colorado (Colorado Springs? then thru Colorado on I70 thur Ike then to Utah back down thru Arizona and New Mexico. With about 22,500 total miles on the truck I averaged around 23-24 MPG overall, towing and regular driving. Last highway trip of 350 miles to Dallas averaged 28.4. That is all good news, the BAD news, someone decided they wanted my truck and it was stolen two weeks age. Will replace with a 2023 Silverado LTA, Z71, Texas Addition with the 3.0. Hope I will see the same numbers you are getting with your 2023. The video was great and you addressed what a lot of people think are "issues" with the diesel.

[@blancs3030]

With this truck I consistently get 1 to 1.5 mpg better hand calculating than the computer. Def at the pump is usually $9 a gallon and I put in 2.5 gallons every 3500 miles, not a big deal. I can order oil and filter online when buying 3 changes at a time for around $60 a change, pretty similar to my gassers. Fuel filter is $15 change every 30k, not a problem.

The Def crowd need to be quiet. If you're such a peasant that you're worried about $20, every 3k miles, then you aren't in the market for a $65k truck anyway

[@ALMX5DP]

Sure, but then begs the question why so much of a emphasis on fuel economy.

[@CatholicBossHogg]

​@ALMX5DP I mean, I agree that if you can afford a 65-70k truck then fuel prices don't really matter for you anyway. However, fuel economy also comes into play with how often you have to stop to fill up. I have this same truck and I really like only having to fill up once a week. Also, fuel expensives are obviously much larger than Def, so it will always make more sense to look at mpg.

[@ALMX5DP]

@@CatholicBossHogg I have a 36 gallon tank, and though I don’t get particularly good fuel economy it means I can go multiple weeks without filling or up to 800 miles on a road trip. So in that respect fuel economy doesn’t make sense to look at for me.

[@CatholicBossHogg]

​@@ALMX5DP well this truck doesn't have a 36 gallon tank and the time between fill ups depends on how much you drive. I get 700 miles per tank but the tank is only 24 gallons. So once a week is impressive.

[@ALMX5DP]

@@CatholicBossHogg sure, just saying that talking about fuel economy is kinda similar to talking about DEF usage (which could also probably be calculated in miles per gallon).

Have a Dec 2022 GMC Denali Ultimate with Lm2 diesel. In total agreement with Tim. Simply awesome! No diesel noise. No smell. Great mileage 24-33 mpg and I live in the mountains of Tahoe (my prior Ford F150 King Ranch average 14-15 mpg) . Great towing at low RPM. Comfortable ride. Best truck I've ever had. I think GM should do some scientific validation for environmental values of these diesels with all the filtration and greatly increased MPG. Might help dispel the "dirty diesel" perception and spread the option across the future lineup. Another point for long-term is to consider the lifetime values of lower RPM torque vs gas and generally stronger build of diesel vs gas. And factor in Inline 6 vs V8. Have a friend with a similar GMC Denali with the 6.2 liter gas and he's getting 14 mpg and it requires premium 92 octane. Great points and video Tim! Bet you'll regret next year when you have to let go of this one. It'll be a 'take one for the team' moment for you.

[@rockymountainjazzfan1822]

Two comments about Diesel Exhaust Fluid: pretty much, DEF is DEF. It's all the same chemically. Second, DEF usage in any given vehicle, is largely a function of how much fuel is being consumed. Use more fuel, use more DEF. When it comes to your using the transmission manual shifting to control your descent, you are exactly correct. You could teach the guys at TFL something about how to use gearing when towing on long mountain downgrades. By the way, I'm a Colorado native that has towed and driven trucks in the Rocky Mountains for over a half-century, I no longer live in Colorado, thanks in part to its leftist politics, but I've been mountain driving for likely over 400K miles.

[@Flathead40]

DEF usage usually depends on the how hard the engine is working (exhaust gas temps), the hotter the exhaust the more nitrogen oxides produced and thus the more DEF needed to stay within regulation. Curious to see if you broke out the def cost and extra fuel cost to see what the efficiency would equate to in miles per gallon of gasoline. Still I think if I were interested in a GM I would go with this engine. I hope it ends up being a home run to push the others to bring back diesel half ton options.

I was going to do a cost per mile analysis. I’ve done it before on other videos and I find it pretty close to gas. Honestly, I was in a rush to get this video out and I spent hours editing. It was really just a choice in editing and how much more to put in this video. Plus, I assumed everyone’s situation and fuel prices would reflect a different cost per mile result. I might do a follow up to this video with the math. I find it pretty interesting.

[@donhappel9566]

I have a '22 LM2 with about 30K on it now and find that under normal daily driving DEF usage is minimal. At least 5K on a tank. Now when I put my 8300 lb tall trailer on it I drink the stuff like crazy, but for normal use it's just a non-issue.

[@genenewton7802]

​@donhappel9566 '23 RST 3.0 with max towing. Echoing all your comments. Drinks DEF while under a load. My only complaint is a lack of towing mirrors in a max tow package!

[@shoelesstrucker4414]

I drive a transport truck for a living and all diesels "regen", most of the time it will do what's called a "passive regen". The system will regen while you are driving and you won't even notice that it's happening. If you spend a lot of time idling then you will be prompted to take the vehicle on a highway cruise so the system can regen but most of the time it takes care of itself. Point is: don't idle!! The new emissions systems on diesels don't like to idle at low rpm's because the engine does not create enough heat to burn off the soot from the combustion process, and the EGR is feeding the intake stream a bunch of garbage which all leads to expensive repairs if not treated properly. I also have a 3.0l diesel pick up and I have added 1 jug of DEF in just over 1 year/6,000 miles of driving. Hope this helps. Scott

[@spencerwiesner4493]

Have this in the 2021 RST. Did a trip from SLC to Moab and averaged 31mpg. Best 50 miles was 38.8!

[@slocavky]

Your truck has a 5.3 gallon DEF tank. Also the LZO has 2 DEF injectors in the system unlike the LM2 truck. Really wish the exhaust brake worked better. Its super weak IMO. Great video as well man keep up the review with the LZO

[@rgnewlife6622]

Hello, okay I truly love this truck!!!! Looking forward Lord's willing to getting one of my own. Thanks for your time and help!!!! Hope you have a super blessed day 🙏

[@deltabravo1257]

18:25 I'm like you.... I don't care what a diesel costs to drive, service, etc. I bought a diesel truck for the power and less stressful drive due to that power. I actually own two Duramax trucks - a 2009 LMM 3500HD Dually that I bought new, and a 2017 Colorado 2.8L that I bought in 2021 that only had 9025 miles on it when I bought it.

[@ejc07305]

Lol, I am from Nebraska, too. Feeling guilty about running into use the restroom and not purchasing something is so Midwest! Quick tip, sometimes I just top the tank off to "relieve" my conscious!

[@Pickuptrucktalk]

I HATE running into a place to pee and not buying anything. Feels wrong! Glad I’m not alone.

[@wushock92]

Tim's Ike Gauntlet. 😆I have rented a few midsize SUVs for long trips from South Central Kansas to New England and none of them got anywhere NEAR the fuel economy of the Baby Duramax. If I had the money, I'd buy one in a heartbeat. One thing about diesel fuel prices, while gas prices have been all over the place, diesel has stayed pretty consistent. Makes trip budgeting much easier. Thanks for your input.

[@jimmerriman6920]

You're fine. There are people out there who just like to argue! Period! They like to argue. I'm considering a 2024 model. We'll see, but 30 mpg is excellent! I was thinking I'd be ahead of the game if I got 26 mpg.

[@robertpulliam9973]

I drove a school bus for 6 years, the only time regen was a factor was when it started when I was at the school picking up or dropping off kids. Then I would shut it off until I was empty or loaded. Lol

[@a-yates]

Love the fuel economy in this truck best so far has been 36.6 mpg on the highway and with the def i used about a gallon every 2k miles so far

[@robm3357]

Your not kidding the mpg is amazing on the diesels. The torque, the tow mpg, unbeatable…..

[@parksperf1]

LOL! (Many laughs!) "Hello, that's Still 30 MPG!" Nice. A very nice video. Yes, This truck is on the Top of my list. Thanks Tim.

[@birddogbriar4335]

I got a 1500 RST about 2 months go. Love it so far with about 2500 miles on it. The fuel economy claims haven't let me down. 26.5 mpg on a weekly basis where I got 15.5 in my old truck. My best over 50 miles on the highway has been 35.5. Haven't towed with it yet, but will be soon.

[@birddogbriar4335]

@THE DUDE diesel is about $1 more a gallon. I can run 2 weeks on a tank of diesel right now . Older gas truck I went thru a tank of gas a week. I've only gone thru about 2.5 gallons of def in 2500 miles. That is pretty much nothing. No one is making you buy a diesel or watch these videos. Take your whining somewhere else.

[@jimlong4259]

Thanks Tim. I picked up my 23 high country yesterday. Lots of opinions on break in before I can tow.

[@Pickuptrucktalk]

Break in isn’t a big thing anymore. Just drive it and vary your speed for the first 500 miles.

[@jimlong4259]

The dealer said drive 1,000 before I tow. My Travel Trailer is 5,400#. I hope I can Tow after 500

[@Pickuptrucktalk]

@@jimlong4259 Not being rude to the dealer, but check the owner’s manual. That should be your bible on this truck.

[@Rift45]

Great stuff Tim! Big diesel enthusiast here. I agree completely.

[@jeffreymayes-hy9jd]

Your right it is an amazing package. Right now I have 39,542 miles and lifetime fuel Milage is 30.8. LIFETIME. When you said Milage is usually off by 1 mpg lower mine is between .9 and 1.3 better hand calculated. Yes I know how to hand calculate Milage as I am a 30 year OTR driver and I breakdown everything in CPM (cost per mile). You said your coming to Michigan this summer with a 63? Impala? 409 2x4 quads???

[@Pickuptrucktalk]

1862 Chevy C-10. I’m trying to get the truck ready for the Dream Cruise. You’ll see a ton of videos IF I can make it happen. Right now it is getting a new powertrain and a bunch of other goodies.

[@222aint]

@@Pickuptrucktalk1862 ? that is one old truck. They must have had to drill and refine that diesel by hand. And they had to hunt the dinosaurs they squoze!

[@skidooboondocker]

Love the honest review, keep it up!

[@bertwilson4311]

Thanks for this video. I agree with your assessment 100%. I have 500,000 miles of driving under my belt with these new emissions-equipped diesels and have found them to be trouble-free, quiet and efficient. If GM would put one of these in a 4x4 or AWD van comparable to the the Sprinter, I would have one in my driveway tomorrow. If they made their pickup out of aluminum, I might even go the pickup route with the 3.0L. If they don't want to be creative, how about a crate engine? This thing would rock in old Suburbans, G-wagens, Econolines, and Land Cruisers.

[@donhappel9566]

I too wish this engine would show up in a euro-style van. Heck, if they even offered it in the old-school current van I'd have bought it. I'm self employed and work out of my van and there is just no comparing a pickup for what I need. That said, I sold my NV2500 (13mpg) and bought a '22 LM2 6.5' bed 4x4, put an ARE topper on it and a bed slide, and I'm working out of that now getting high 20s mpg. I did find the topper took a few mpg off of it as it sticks out wider and a bit higher than the cab; must really kill the aero of the truck. W/O it I was able to be 30-32 regularly on highways. And all this from a Ford guy!

[@waynehawkins9090]

Still love my 21 Silverado. Have the LM2 and best mileage was 30.2. I have 16,466 miles on the odometer.

[@hammer-r]

Here in flat illinois and with a truck with only 1200 miles so far, my highway at 60mph I’m getting over 40 mpg. My 5.3 doesn’t get any where near that. Don’t worry about the negative ninnies, let them buy gas. Around here gas and diesel are very close. In fact diesel at Costco here is cheaper than any gasoline station in my area. Love the truck and can’t wait to trailer my Rv to Colorado this summer. Maybe we will see ya on the road. Cheyenne is a killer for two reasons, altitude and that friggin wind. It’s always windy and always in the wrong direction. Lol

[@Pickuptrucktalk]

When it stops blowing in Cheyenne, people fall over. They are so used to leaning into the West wind.

[@hammer-r]

@@Pickuptrucktalk lol. Yup. I made the mistake of taking my truck and RV thru there a couple years ago since it’s the best way to Laramie. What a mistake. Altitude and wind. The main reason I retired the avalanche from towing and bought the Silverado with the 3.0. Keep the vids coming.

[@Griz5340]

Just finding your channel = LOVE IT

[@AmyCastro78]

Can not wait to get my 2023 high country with this motor. 2 more day!

[@craigwilliams1073]

I'm noticing I can drive from Detroit Michigan to Bowie Maryland without filling up! Plus, all those increased costs are less frequent than the gas counterparts! In essence, cheaper over time and distance!!!! I'm still finding more mind blowing fact about this truck!

[@scallahanco]

Do not forget if comparing the 6.2l vs 3.0l, you need to compare the diesel price vs premium or mid grade prices so the difference is not that large. Also the 6.2l is about 2x more cost when purchasing new.

[@RK57AZ]

Hey Tim, Nice segment on fuel economy with your High Country. You gave a pretty in depth detailed summary of all conditions that can and do affect fuel efficiency but, one thing was missing from your story? It doesn’t have anything to do with mileage? Can you guess what it is? Okay I won’t keep you in suspense any longer. It’s seat comfort after 8 hours and 500 miles! If you had any issues, you might try what has worked for me in my 07 SLT Yukon, 03 GX 470 and even on my 15 Rubicon JKU. I will turn on the seat heater and that seems to do the trick. Not sure if it softens up the foam cushion or relaxes my back/ butt muscles or both? The Jeep only has two heat settings and only bottom cushion heating but, still works pretty well for me. I have a compression fracture to L-1 and am fused from L-4 to S-1. So every little bit helps! The back and bottom cushion heaters are the most effective at reducing discomfort. Stay safe and healthy! Ron

[@Pickuptrucktalk]

I talked about it and unfortunately cut it out when editing. My fault. My advice is test out different trims. I think, and it’s a theory, the high country trim has the most comfortable seats out of all the other trims. I have some back issues and this High Country was pretty comfortable overall. Not amazing like say the Nissan Titan seats, but good enough for me.

[@ronhayes832]

The price spread between gasoline and diesel has begun to narrow. In Dallas on 4/21 the price of diesel was identical to gasoline at $3.29. Now, the payback is easily calculated.

[@anthonygasparini1734]

You have the best informative videos. Tim, thank you!
