2023 Sierra 1500 AT4 3.0L Duramax Diesel 650mile roadtrip tested

[@CypressRacing]

3.0l is tragically underrated. Such a great motor that's so often overlooked.

[@donovankelly7723]

Nice to hear since I just bought one over a week ago 😇

[@Silveradodreams]

I drive at 65 on the highway, you don't save much time going faster but you save a ton of money. I get 32 mpg on highway with my 3.0 with hybrid tires and bed cover.

[@matthew5027]

I get 13.5 average in my tundra. If I got anything over 20 I’d throw a party

[@jairusfojas8788]

Great motor. I achieved driving 700 miles in one full tank of diesel.

[@johnnylexworth363]

I’m hopefully buying this same spec truck her soon I’m very excited, first new truck at 22 hopefully it treats me well

[@brucemacdonald4672]

Picking up my 24 next Wednesday. Traded my 2014 Toyota tundra 5.7 in on it. We will see,loved my Toyota,but the fuel mileage when towing.

[@CharlieLarkin75]

Considering the shape and weight of what that engine is trying to drag around, I'd call that net result pretty impressive.

[@brucecranford0824]

Just bought a 2024 AT4 with the 3.0l diesel. So much power. My goodness. And, if you keep your foot out of the fuel rail :-), it gets crazy good fuel mileage. Just sips the diesel. Lovin' this truck!

[@codered9576]

Still at the end of the day it does a heck of a lot better than gassers.

[@epbski]

I'm a diesel fanatic, especially German diesels. In North America, that's a lonely thing, as few diesel models have ever been sold here. It's a shame that diesel cars have been so underappreciated in NA. Honestly, a lot of vehicles, especially pickups and SUVs, make no sense to me unless they are diesel. There still seems to be a misunderstanding outside Europe that diesels are slow, dirty, etc. The array of I4, I6, V6, and V8 diesel options in Europe from VW Group, etc. makes me so jealous.

[@johnduff3914]

It's about $4.70 in NYC.

[@bradbucklin2692]

I was able to get 27.4 with the same truck but 2022.5 Mine has a 6” lift with 37s Looks amazing and drives fantastic But the around town MPG is horrible Still nothing impairs to my 2019 ZR2 Duramax 44+ mpg and it’s a mountain goat

[@robedmund9948]

Around town driving (short trips) doesn't allow the motor to get up to temp where the efficiency lies. Let the motor warm up (especially if you have the remote start option) for 4-5 minutes, especially on colder days. You will notice a difference.

[@angelolamantia]

If you use the open roads program you can get diesel for .50 to .60 cheaper per gallon at truck stops, you do have to use the truck lanes.

[@danzante85]

Thank you for posting and sharing such a thorough review. I just purchased a 2024 1500 ZR2 Bison with the Duramax 3.0 LZO. Given the owners manual recommends the use of only top-tier diesel and how scarce access to such diesel is not only in my area in California, but also nationally, lam wondering what other Duramax LZO owners use to fuel their trucks.

[@jmsmikey]

I'm in Las Vegas & we have diesel at every Chevron. Do you have Chevron in your area? Is that top tier?

[@MrJockStrap]

By top-tier, it just means not red-dye or industrial grade diesel. Any diesel from a pump is fine.

[@Barrett_Fodder]

True on the restricted use of Ag diesel. Past that the minimum cetane level of US diesel is something like 25 points lower the EU spec. My 3.0 turbo diesel performs better with routine use of Power Service silver bottle.

[@caleblewis3463]

Sounds like you’re trying hard to not love it. I think it’s a hell of a step up from your broken car.

[@ForgettingTheFear]

You’re right I agree

[@lanceevans4053]

Mine is a 23 and just said low voltage and turned my brakes off while driving, such a piece of trash and GM said they haven’t seen enough others to do anything about it

[@jcasto7343]

I hear the seats are super uncomfortable?

[@naterossman8202]

I have the same results with my Silverado with the baby duramax. Highway driving in warm weather gets great fuel economy. Winter, not so much. Very smooth ride and great torque

[@BrandonSantino]

How much to fill that tank from E

[@TryingYourLvck]

Houston Tx... in the city reg 2.89ish. diesel 3.50ish outside the city on the highways.. reg 240ish diesel 315ish

[@CodyLeon]

That must be a great buddy to let you borrow a 2024 truck

[@mrwigglebutz5061]

The AT4X is way outside my budget...but how do the AT4 hold up with city driving (3.0 vs 5.3)? My commute is a maximum of 10 miles, but is 100% city. I do some highway driving time to time but primarily suburban USA. I currently own a 2023 Tundra (8,500 mi). I love the truck, but the premature engine failures have me concerned. Dealers aren't even accepting 22/23 trades because of the issue and toyota dealerships can't sell impacted inventory until their is a fix. I bought the extended warranty because i planned to have this 15 years but not if an engine blows!

[@robedmund9948]

On that short a driver you will not get the diesel up to operating temps, especially in cold weather. That will affect mileage.

[@robedmund9948]

Check out the 2024 Trail Boss edition. VERY similar to the AT4 and one helluva a LOT cheaper.

[@mrwigglebutz5061]

​@robedmund9948 thanks for the comment. Will check that out!

[@stans1058]

If you slowed down at highway speed you would have surpassed 29 MPG. Probably better than 31 assuming you don't have a high rear axle ratio.

[@donovankelly7723]

Texas in November, diesel is $2.99

[@JohnFichtner]

You can sue the state of Michigan for the loss of your car because of the neglect of the DOT. I did it and was awarded a win...

[@austin_does_stuff]

thanks for your reply - do you have any resources you'd recommend I try to use? or links to when I could submit a claim?

[@stevenpeterson7234]

Awesome truck man!! Great mpg!! My 23 Nissan Titan Pro-4x gets the same mpg tho!! I have a few mods tho

[@jimmyjack7141]

Diesel is 3.69 in east central Florida

[@robedmund9948]

In the winter, use a grill cover to retain heat in the engine bay. 28 mpg for a full-sized 4x4 pickup is awesome!!

[@slscamg]

I think a lot of that phenomenal feel economy on the first day was your low average speed. I know I get the same fuel economy in my truck that’s a 3.5 L eco-boost no matter if I’m driving in the city or the highway. About 17 in the city and maybe 18 on the highway, but keep in mind with our highway speed limits, I’m traveling 75 to 85 miles an hour. No matter how dynamic they make these trucks they’re still a giant box. It takes a lot of energy to push them through the air.

[@dopeboyp3487]

I’m in SE Michigan as well. Do you know any fuel stations where I can fill my DEF at the pump?

[@ramseynicholson7902]

Loves is generally where I head to. Not many around me but one that I pass weekly to commute to my girlfriends house the fuel pad is always empty so you can sneak in and get it pretty fast. Kwik Trips in Wisconsin rock as they have the DEF pump where you can pay right at the pump with a regular credit card!

[@pallas5446]

Diesel at Sams club in florida 3.30 a gallon. Your governor wants to cut pipe line wait if that happens

[@patanasoff7]

Here In Washington State, prices are way over $4.00 a gallon.

[@fatman5377]

Same here north east. 4.2-4.7

[@mowcowbell]

$3.18/gal for diesel in Okla City as of 07/29/2024.

[@Ronadams5272]

Winchester, Ky. Diesel is under 3 dollars a gallon on Friday the 13 th 😮

[@Ronadams5272]

Love my 24 duramax best mpg is 36.8 avg is over 30. Uses very little def fluid, use start stop feature, don’t let it idle, will kill mpg , very impressed, killer torque !

[@lonerider72]

"Thanks, Karen." - that made my day

[@brunozanon2325]

The truck might have been in Regen mode

[@5660foster]

How much DEF did you have to fill with on those trips?

[@HomesteaderJake]

Mine runs about a gallon per 1000 miles, add a trailer and it drinks a lot more.

[@tmntrc56]

AT4 isn’t what you displayed at the beginning on the MPG guide.

[@Michael-ox4eh]

Like my 3.0 duramax ❤️❤️❤️ this is best engine ever

[@lancecorporal9894]

Get what you vote for - well said. Your buddy’s lifetime average was probably due to him driving in the city

[@rafaeljasso8120]

Brother 7 dollars. California

[@B-rad303]

I wonder if your roads are as horrible as Colorado? Our governor doesn't do shit for fixing anything

[@ryansommerfeld2098]

Only in the areas that “matter” to the donors who keep getting the “progressives” elected. The poorer people outside of the wealthier parts of town don’t get equal distribution of the weed wealth.

[@fluffywarhampster]

Pretty much all vehicles get horrible fuel economy in cold weather so your result isn't remotely concerning.

[@Boomafoo420]

$4.00 a gallon is insanely cheap lol. It’s like $6 in LA

I gave you a like at "ya get what you vote for." Hopefully, enough people with functioning minds will vote Red up and down the ballot. It would be nice to see Michigan flip, one of my favorite states (upstate LP and UP).

[@eddiek2497]

Mf bιτching about gas prices as if he isn’t driving a 5000lb truck, and the entire planet isn’t dealing with fuel shortages as well. Bιτchιng about the roads as well. Have you seen I-75? Michigan has been building that up ever since I left for the Marines. 3.0 seems like a nice engine though. My buddy who’s a technician in Flint has other opinions about it, but I have hopes for it.

[@matthewprather7386]

The economy is great which causes demand for fuel which increases fuel prices. So if you want lower fuel prices, vote for the guy that tanks the economy.

Right? Nov 5, 2020, XOM traded for around $35, today it's at $119 with a juicy 3.80 dividend. If all these loudmouth trump supporters were capitalists like they claim, they'd own these stocks and enjoy the profits.

Sorry you are misguided and offended brother, wishing you the best

Well, there is this thing called inflation-better call the fed. Also, added taxes. Its econ 101

[@irishsoccerguy]

Everyone got a tax cut. You're just too stupid to realize that.

[@nickturner5185]

Gas companies were price gouging when we had the lowest prices in 20 years? Makes sense
