2024 Duramax 3.0 MPG Test Results. Did it Beat Expectations?

[@fran2395437]

Got my 24 elevation in May and wow!! Coming from a lifted 17 Tundra w 35s but was getting 11-13 mpg! Drove from California to Nevada,during brake in period and got 39 mpg!! It shook me lol. Loving the truck,just hoping it holds up with no problems like my Tundra did..

[@dopeboyp3487]

I got my 24 AT4 1500 a month after you, and I’ve experienced the same great MPG’s. 38.8 is the best I’ve seen, and it wasn’t all hwy miles either. Just insane what these monster sized vehicles can accomplish with the Duramax. So glad I didn’t go with the V8… And the 3.0 sounds damn good too!

[@russellhankins7522]

Just bought an new Duramax in Phoenix. Made a trip to Yuma and did some tests. At 80 mph averaged 24.9 gpm. Dropped to 75 mpg and got 30 mpg. It was nice having a 600 mile per tank range.

[@HighAnxi3ty]

I just purchased a 2024 GMC 1500 Sierra Denali Ultimate and on a round trip of 140 miles.. in 2wd (not 4wd Auto) and keeping it around 65 mph it's best was 36.9 mph and the overall average for that trip 35.3 mpg.

[@travisseymour4320]

I bought a 2024 AT4X 3.0 three months ago and have right around 5k miles on in. In my experience so far, I am getting better and better fuel economy as the miles add up. I get mid to low 20s in the city. On the highway, the sweet spot is around 65-70 mph, but here in Texas everyone is going 80+. At 80 im getting 20-21, 85 mph gets me 19-20. Not mad at those numbers at all with a lifted truck, 33" tires, 4wd, front and rear lockers, etc, especially since my friend got the powerboost around the same time as me and I'm getting better mileage 😎

[@chaseydog7956]

I have just over 7500 miles on my 24 AT4 3.0L. I'm averaging 24 mpg city driving. Hasn't really changed any overtime. I've made one long-distance road trip and averaged 29 mpg. Congrats on the new truck.

[@TMRI1970]

@zrowe2010 Same here with my 2024 Denali. Cruising at 72 mph (cruise set) I'm averaging 32-34 mpg. I did get stuck behind a semi truck one time holding 65 mph and I averaged 38.4 mpg!!!simply stunned by this baby max diesel!!!

[@donovankelly7723]

I also have a 2024 AT4 3.0L but so far I'm ranging from 15.5 to 21 (at best) mpg in the city (I bought my truck pre-owned with 9308 miles on it...so it's just now getting broken it). Quick question: what are your distances in your city driving? My trips are largely around 1-2 miles with some exceptions. Thanks

[@chaseydog7956]

​@donovankelly7723 6 miles each way to work. The dog park is about 3 miles from home, and we hit that pretty much every day after work. Longer 40 - 60 mile drives on the weekend are not uncommon. I'm pretty light on the accelerator.

[@dopeboyp3487]

Slow down a bit brother. I set my cruise to 69 on the highways here in Michigan, and when doing so I’m easily averaging low 30’s on even short trips. In the city I’m in the high 20’s, and the best I’ve seen was just under 39 mpg’s. I have a 2024 AT4 with the LZ0! Great video by the way!👊🏽💯

[@4961Studebaker]

Thanks for filling at QuikTrip- if it really matters - Auto Diesel typically will have a lower Bio Fuel percentage if the store has both Commercial truck and Auto Pumps. Middle of summer both will be B20. Colder months Auto will be between B5 or 11.

[@nq2847]

can you elaborate? Possibly getting a diesel in the future. Thanks.

[@BradenElChil]

@@nq2847 The comment refers to the blend of biodiesel used in diesel fuel sold at gas stations, specifically the difference between diesel at pumps designated for commercial trucks and those for automobiles. Here's a breakdown: 1. **Biodiesel Blends (B20, B5, B11)**: - Biodiesel is blended with traditional diesel fuel in different percentages. The "B" number indicates the percentage of biodiesel in the blend: - **B20** means 20% biodiesel, 80% petroleum diesel. - **B5** means 5% biodiesel, 95% petroleum diesel. - **B11** means 11% biodiesel, 89% petroleum diesel. 2. **Difference Between Auto and Commercial Pumps**: - **Commercial truck pumps** may have higher biodiesel blends because large trucks often use fuel systems designed to handle these blends better. Biodiesel has a slightly different chemical structure that might not perform as well in smaller auto engines, especially in colder temperatures. - **Auto pumps** tend to have lower biodiesel blends, especially in colder months, where biodiesel can gel and cause engine issues in colder climates. 3. **Seasonal Variation**: - During **summer months**, higher biodiesel blends like **B20** can be used across the board (both auto and commercial pumps) because biodiesel performs well in warmer weather. - In **colder months**, auto pumps may offer lower blends like **B5 or B11**, as these lower concentrations of biodiesel help prevent fuel from gelling in low temperatures. Commercial trucks might still handle higher biodiesel blends due to their engine design and heavy-duty fuel systems. In summary, the comment explains that diesel fuel's biodiesel content varies by pump type and season. Commercial trucks might use higher blends consistently, while auto pumps reduce biodiesel content in colder months to avoid fuel performance issues.

[@nq2847]

My 2024 3.0 Silverado LTZ max tow has been great. Averaging anywhere from 28 to 32 MPG on my typical highway drives. Speed limits here making 80 MPH pretty uncommon (the speeding ticket for those speeds is brutal). The fuel economy will improve as the rings seat and the transmission and differentials break in. My average improved 1-2 MPG over the first 5000 miles.

[@karlschauff7989]

3300 miles on my 24 Silverado LTZ 3.0 max tow and I love it. 25 mpg at 80 mph. 60 mph on rural highways will typically average 29 to 30 mpg. My fuel economy definitely began to increase after the first 2000 miles. The AT4 and Trail Boss/ZR2 variants have a lot more aerodynamic drag so don't expect the crazy high numbers some 3.0 trucks are getting. It's up to you, but I strongly recommend a fuel additive like Hotshots EDT, Archoil 6400/6500, Techron Diesel Treatment, Stanadyne, etc. Unlike gasoline, the Top Tier program for diesel fuel pretty much fell through, so most diesel fuel doesn't have detergents that they're supposed to have in them. The additives I mentioned had the detergents that keep injectors clean and reduces the frequency of regens.

[@richvangorder3900]

I like the idea and the fuel mileage is always better that a gas variant but the back end always gets you on maintenaince costs. In Texas diesel is MOSTLY $1 more than gas on the regular(not now). DEF costs, fuel filter costs and more oil for the pan.

[@TmanBlades]

I also live in Az and I drive a 24 Tundra non hybrid platinum. At 75mph driving the 101, I-10, and 202 you won’t get the advertised mpg. While we don’t have long uphill grades the 101 and the 202 are not flat and I find driving 75mph I might get the city rating of 18mpg on the highway. If I drive at the speed limit or maybe 5 over I have been able to achieve the advertised 23mpg highway but the conditions have to be right. People in Arizona drive fast, including myself, but when manufacturers test these trucks for mpg, half the country has highways that are at 55mph and flat as can be. 25mpg @75mph traveling the entire stretch of the 101 and the I-10 to the 202 sounds great to me. I may have to look into one of these 3.0 duramax in a couple years. Excited to see how the build turns out. Subscribed 👍

The mileage gets better over time. I don't have the lifted AT4 which does impact the mileage. I have gotten as high as 33.5 on extended highway trips and as low as 27.5 when going closer to 80. If you stay between 65 - 75 you should get 28 easy. I generally get 29 - 30 at those speeds but I have an SLT running 33's and no lift.

[@joevitaleconstruction.704]

My 21 Ford dropped 2 MPG when I leveled and added Nitto grappler 33’s (I was getting 16.2]. ..my 24 AT4 duramax gets about 23.5 with the crappy Goodyear tires that humm like crazy. Noisiest tires on earth. Honestly that diesel is super efficient. Doesn’t tow nearly as good as my 21 and feels more truck like. The 21 Ford f150 felt smaller. I think I like the GMC better but definitely miss some things about my FORD.

Seems just a bit low, but with that package maybe not. My 3.0 has around 15,000 on the clock and just returned from a 1,110 road trip and I average 28.7 over those miles using the truck’s computer calc. Mine is a ‘23 Denali Ultimate and while I’m sure MPG did increase after break in, it wasn’t enough for me to notice. Great truck & engine. I had a nox sensor go around 600 miles but hasn’t had a single issue since. Quick edit - the seats still suck, even after 15,000!

[@GearsGadgets]

I am guessing the Denali returns better MPG being it doesn't have the slight lift and off road tires of the AT4. I was kind of shocked that the seats didn't bother me after the hour or so I drove but I will be curious to see how they are on a 3-4 hour drive.

My experience with diesel engine break in is that they seam to be as good as they will get with about 40,000 mile on them. This is in reference to the 5.9 and 6.7 Cummins. It will be interesting to see how your journey with the 3.0 Duramax plays out. I currently have a new 2024 F150 XLT Powerboost 4x4 , 6.5' box. First tank of fuel through it produced 19.3 mpg hand calculated, the gauge on the truck was optimistic with a reading of 20.1 mpg. My driving to this point has been rural with a small amount of city driving.

So you expect to get great results for fuel efficiency while driving at 75 MPh. Try this out do the same thing only at 55 MPhil,and observe the mpg.😅 I own a 20 year old Ford diesel and get 24 mpg,at 55mph. You can not expect to speed/ and get efficiency. There is no need for breaking in new vehicles, the high quality and technology have superceded the old school engineering. Great video this shows everyone that you have to be careful not to through fuel out the tail pipe. ❤

[@GearsGadgets]

@@DAH1020 If I did a video at 55 it would end with me being rear ended as the speed limit here is 65. The reason I do it at 75 is because it’s not uncommon for the average person here to be doing 80mph. Real life testing by real life people, not doing 55 mph in hopes to get a shockingly unrealistic number for where and how I drive. Hope that makes sense. I think it’s typical for the average person to add 9-10 mph to the speed limit on cruise control gaming the fact that 99.9% of cops aren’t writing that ticket.

I had a 21 Silverado 3.0 Duramax, and I’d say the error you’re seeing in the computer is partly due to the small sample size. You will get some variation in your tank fill as well. The relatively poor mileage you’re seeing is related to your speed. Cut your speed down to 70, and then to 65 to make some comparison runs. I saw as high as 31-32 in short runs on level ground. Keep your foot out of it a bit, and you should see 26-27 or so. As it is, it appears to be considerably better than the hybrid.

16.2 and 21.1 mpg in your Powerboost is crazy. I've never gotten less than 21 unless I was towing or hauling full loads. I also use Fuelly and after 42641 total miles recorded I have an average of 22.6 with a best of 25.2 mpg. My lowest ever was 11.7 trailering a dual axle enclosed U-Haul through the Texas Hill Country with a grand piano inside. I always used regular until the past couple months where I decided to run premium to see if there was a noticeable difference. Believe it or not, I found about .5 - 1 mpg improvement, especially when running heavy. Also, daily driving is 50/50 road/hwy, 50 mi round trip 5 days/wk. Hwy mph usually 72-73 mph. I find that the gives my particular truck the best return. I started using fuelly close to 10k miles into my ownership so it's not accounting for the full 51k miles I've got. I can also say that as the truck breaks in, it performs better and is becoming more efficient. I'm not a GM fan but give props to the 3.0 Duramax. I'd consider it if hard pressed to replace my truck. But unlike you, I've had nothing but good results with my 2021 XLT 4x4 Sport 302A High pkg F-150 and love it. It's smooth, quiet, powerful, and above all, it's been ultra reliable.

Coming from the PowerBoost, what are your thoughts on idle sound/noise? The one thing I am not a fan of is the sound of a diesel idling.

[@GearsGadgets]

Personally the diesel doesn't sound all that loud to me. If you compare it to a 6.2L you can basically swap the sound of injector ticking with the sound of diesel clacking. Of course neither are as silent as the slight hum of the Powerboost but when comparing the diesel to a gasser, I think they do an amazing job muffling the clack.

Maintenance is the same as a power boost

[@mll7674]

@@PopCorn-ei5bj how do you figure. The fuel filters and oil for diesel engines are more than what you spend on a power boost. Seeings the power boost doesn’t have fuel filters. And the oil filter and oil for the boost is by far cheaper. Good try. I drive a 3.0 Duramax. I know. I was a booster owner once. Not anymore. Try again. Also the cost of fuel and def. Sorry man. The only saving grace is the 30mpg I get with mine. Had ford kept the baby power stroke I would have bought it. But I am duramax owner now. Hope it serves me as good as my old Cummins did back in the day. Second gen common rail was a great truck.

[@polarys425]

You have the 18's with a more aggressive tire. You won't get the mileage that the 20's and 22's will get with the more road type tire.

[@tunnelvision2day]

I know 3 ppl with ur diesel engine. And they all claim they get 27-30 mpg.. So I was really expecting u to get better on a highway loop.. May be break in like u claim.. But theirs are a few years old. And I've heard due to EPA, 2024 model diesels are drinking more fuel, and twice the Def fluid when compared to 23 and older..

[@hochhaul]

75 MPH plus it being an AT4 goes a long ways towards dragging down his fuel economy he was going to get. It may improve with more break-in but it's pure physics when it comes to big knobby tires, a lift that increases aero drag, etc. Regens can also hurt fuel economy averages.

[@utepminers39]

I cruise mine at 63mph and get 28ish mpg

[@timgaudreault8198]

When my truck has a tail wind it gets in the high 30s.

[@jamesobrien3076]

If you keep your highway speeds closer to 65 you’ll get closer to 30 mpg.

[@jimsheldon3788]

I had a 2014 Tundra 4.6 litre and got 14mpg no matter what. Traded it for my GMC DENALI 1500 3.0 duramax and get 26mpg average. Best mpg so far 35.6mpg. Never look at Toyota Trucks again. Praise the Lord I saw the light! Go President Trump to get fuel prices down even more.

[@lawrenceburbridge9033]

at 65mph instead of 75mph should show a huge difference then 23.+ I would think at 65mph you would easily see 25.+ with a new truck

[@karlschauff7989]

The fuel economy numbers start to climb after a couple thousand miles. The engine and differentials have to break in.

Driving at 75mpH, It's no wonder you got piss poor mileage with your F150. I get 21 to 22 in my 2021 XLT with the 5.0 by keeping it below 70. Terrain, speed and mods all play a role. You seemed disappointed at the 21 mpg with your PB but look at what you did to it..If you're concerned about gas mileage, don't mod your truck.

[@GearsGadgets]

Multiple things to address here. 75 mph is the speed I set because the speed limit here in Phoenix is 65 mph and nobody (including me) does 70 mph with the exception of a rare few old people who are more likely to create accidents for not keeping up with the flow of 80+ mph traffic. So my tests are real world, keeping up with the flow of traffic tests. I am not trying to hyper-mile my way into an unrealistic and unsafe result. Below 70 mph in Phoenix is flat out dangerous. I am not saying I am disappointed by the 21 mpg in the PB but I am saying I was underwhelmed by the fact that I never one time got advertised MPG. Watching THIS video, you will see even with my CRAZZZY 75 mph speed, I still surpassed the EPA estimate of 23 mpg highway. So comparing the PB to the Duramax, the Duramax absolutely is better at achieving EPA estimates in a real world scenario that doesn't require me to set cruise control at put everyone on the highway in danger. If you also listened to what I said in this video, MPG isn't my only concern, I am okay taking an MPG hit from modifications BUT my goal is to minimize that hit as much as possible. I have far more faith that the Duramax will be a much better fit for that scenario based on the results of this test.

[@theblunden2]

I was born and raised in Tempe and moved across the country 8 years and miss the roads/highway in the valley. The speed limit on most highways here is 60 mph and most people drive 55 mph if you're lucky and there are accidents EVERYDAY..... In Phoenix there's a method to the madness aka the flow of traffic is a thing. I remember almost everyday on my way home from work on my motorcycle I would ride halfway home with a Tempe motorcycle cop staggered going about 15 over and we would give each other the motorcycle wave as he exited the highway.

[@RobVarley]

Is that what the computer is telling you?

[@karlschauff7989]

Some people don't have the choice to drive less than 70. You'll get rammed off the road driving that slow in some areas.

[@kasb58]

@RobVarley I used Forscan and engineering mode to adjust my computer where it matches manual calculations.

[@robertletulle]

I have a 3.0 lifted 6 inches and 37 inch tires, I average 30 city, at 80mph on hwy I average 100mpg!, towing 7K travel trailer through the mountains at 70mph I once got 20mpg uphill on the ike gauntlet. all hand calculated!! Stop with the B.S. post real real numbers, hand calculated, at real speeds. Anything under 75-80mph on the highway doesnt count.

[@milanmq2686]

Mine 5.3 2wd gives me 25 mpg why.

[@Michael_M991]

You lifted and put huge tires on the F150 what did you expect lol Diesel will always be better than gas when it comes to MPG. The Powerboost is a better truck hands down.

[@GearsGadgets]

@@Michael_M991 I acknowledged that I lifted it and put bigger tires on it but I also said I never saw 24 mpg as advertised before I ever did a single mod. Point is my F-150 never got close to the advertised MPG stock, the Sierra exceeded advertised mpg immediately. That isn’t insignificant. MY Powerboost was a complete failure. Nearly 10% of my ownership experience the truck was in the shop. So while I appreciate some people love their Powerboost and have no issues, my Ford experience was atrociously bad. Ford was “hands down” the worst vehicle I’ve ever owned period. So as I said in my video, I am fine with an MPG hit after modification, I would like to minimize it. Exceeding estimates fresh out of the box is a promising indicator of being able to do so.

[@Michael_M991]

@@GearsGadgets as the last video myself and a few others commented - none of us have had a single issue with ours. Each to their own. I would never spend my own money on a GMC / Chevy product personally. Ram too. On some highway runs I’ve had 27/28mpg in the PB quite easily. So I’m really not sure how you were driving yours. Temps / elevation maybe? Bad fuel?

[@GearsGadgets]

@@Michael_M991 always run premium top tier fuel from Costco. Track every fuel up with Fuelly, not just reporting dash mpg, it’s actual calculations. Ran over 35,000 tracked miles this way. Best I ever saw was 21.1. Even more damning is the averages as reported by 354 other owners tracking fuel the same way averaging 18.8-19.8 mpg which is 4 mpg lower than the 24 advertised. Feel free to to look for yourself. www.fuelly.com/car/ford/f-150?engineconfig_id=921&bodytype_id=&submodel_id= The GM trucks real world reporting on the 3.0 diesel are MUCH better. So while I have no problem with people who love their Powerboosts, I do side eye anyone who watched my videos and see how unreliable my truck was, who question why I would move on to another platform completely. Ford was horrendous in terms of quality and very slow (Ford parts logistics problems, not dealers) to repair when things went wrong.

[@Michael_M991]

@@GearsGadgets all down to driving style, as well as tires and even environmental factors like wind, temps, etc! There's one on Fuelly reporting 26.8MPG too. 🤷🏻‍♂️ The videos are out there. Lots of owners getting the advertised numbers and beating them with ease. I'm sorry you couldn't. Congrats on the new truck I guess. Maybe you had an early post COVID build. Had absolutely zero issues with my Platinum.

Doesn’t sound worth it. Diesel costs more money than regular. I can get 21 out out my hemi.

It's worth it when diesel is within 20 cents of regular. I average 28 on road trips and have gotten as high as 33.7 mpg. If you compare it to trucks that require premium it's a no brainer

[@karlschauff7989]

Is your truck lifted? Does it have oversized, knobby mud tires? This engine makes nearly 500 lb ft of torque between 1500 and 3000 RPM and gets 25 mpg before it's even broken in.
