Do you know if it fits lzo engine as well?
Does this fit 2021 Silverado 3 ltr? Link says it's for Ram
@@alflyer9406 yes the reviews says it does.
will do, thanks
Thank you for breaking down the fuel cost. I am a retired GMC dealer and on the last day I owned my dealership I purchased for myself a 2021 GMC Sierra SLT with the 3.0. The reason I picked the 3.0 diesel over the 6.2 gas was the feedback from my customers and my service technicians. We had zero issues with these motors in the one year that they were available. Chevrolet actually had the motor in 2020 where GMC did not get it until 2021. Since April of 2021 I have driven over 40,000 miles with absolutely no issues. I make regular 900 mile trips to St Augustine Florida and I consistently get over 30 miles per gallon. Unfortunately here in Delaware there is about a $2.00 difference for diesel over regular unleaded right now. I think that difference will narrow when the weather warms up. That won't keep me from trading up to the 2023 3.0 that has more torque and horsepower. In my opinion, if you are towing anything or not, this engine is a no brainer.
Great feedback, thanks for sharing your experience
They don’t make 100k without a lot of down time! I have 114k , 38 trans went out, 93 engine came out to be repaired not replaced, 114 the engine came apart going down the road at 70 mph. 27 mo. Owning 14 mo driving , you tell me I would never buy one , Chevrolet won’t do anything about it!
@@richardcam8870 That goes against tons of testing and customer experience data out there. Lack of proper maintenance perhaps? Incorrect motor oils?
Now remove the emissions like they should have came
Thanks for your reply. I'm going to buy either a Silverado, Tahoe, or a Yukon Denali 3.0 for traveling across the USA a couple of times, and the MPGs and comfort levels are very attractive. I live in SW Washington State and want to travel around Texas where my Father grew up. I'm thinking about trying to make a deal with a dealer in the Houston area and flying down there and driving around Texas, Louisiana, and Florida before driving back home. I think one of the 3.0s would really shine at this.
I have a 3.0 turbodiesel in my 2014 Porsche Cayenne. I routinely get over 30 mpg driving at 80 mph while the EPA says 29. At 109k miles I have changed zero parts under the hood except for oil and gas filters. Driving experience is way better than gas. Diesel believer here.
Nice to hear! Thanks for sharing
Loved my 3.0 Touareg. 26 to 28 mpg. Towed better than my 3.5 ecoboost and got better mpg towing than the f150 unloaded.
Me over here with my merc ml 320 blue tech with no tow hitch 😐.
I have a 2014 Audi A6 with the same engine and average 35+mpg ….but just wait…. The VAG 3.0 diesels have their problems! The motor mounts are probably worn and need to be changed now (at 109k) or will need to be shortly. There is a very common problem of a coolant leak in the valley of the engine which requires complete dismantling of the intake system, EGR system, etc. If you’re not mechanically inclined, this could be very costly, especially for a Porsche (not that an Audi is any cheaper but I did mine myself). Great engines, awesome fuel mileage, very reliable but do need some (expensive) love!
I'm worried about start up in -20 weather. I live in Colorado, so Jan and Feb can get 🥶 CLD!
I like your video. First let me say reliability has been great with my 2022 Escalade. There is no up charge for a diesel option on the Escalade. I live down south. A box of DEF fluid at AutoZone “AutoZone brand “is $11.99 Diesel fuel down here is approximately $4.29 per gallon. So those things being said, it really makes it a solid decision to go with the diesel. Towing is no comparison. Torque is 460 ft lb from just off idle all the way to almost 5k rpm! No other Diesel has this range. Mated to the 10 speed it is an unreal combo. Plus the oil belt issue really isn’t an issue. Who keeps their vehicles that long anyway? If you are one that does, it’s really not that expensive. My dealer says it will cost approximately $1500 to change the belt at 200,000 miles. If the belt goes bad you just go into limp mode. It’s not like a timing belt on an interference engine where everything gets destroyed. The engine is a straight six iron sleeve twin overhead cam design. This is the same as most popular tractor trailers etc. Peterbilt, Detroit diesel etc. it’s a tried and true design. Again the reason for going with this engine is that it is a modern diesel without all of the problems of the old school diesel engines. Smoky loud under powered boat anchors. If you drive one of these 3.0 Duramax’s you are hard-pressed to even hear the diesel sound. Most passengers have no idea they are riding in a diesel powered vehicle.
You make some good points, thanks for sharing your thoughts!!
I'm in ATL and I ordered a Sierra with the diesel. It'll be my first diesel but as you said it makes too much sense. I'm planning on keeping it for a long time so reliability/longevity over the 5.3 was really it.
Thanks for a great comparison.
IMHO, the gov has destroyed the light duty diesel option and if not for the durability and tow capability of diesel engines, they have almost destroyed the mid duty market (2500-5500) as well.
We run a fleet of diesels and I love diesels. I am getting a new 1500 to go from job to job (5000-7000 miles per month).
Between:
1. Fuel difference average of $1.50
2. DEF issues
3. Maintenance costs
We are saving $1000-1300 per month going with gas. The initial vehicle cost is a wash at resale.
We run Ram, Duramax and Ford Towing goosenecks with our 2500-5500s.
The absolute number one problem after the fuel price difference for this stupid ULSD we all are forced to buy, is DEF Systems. Every single truck we have has issues after they get some miles on them and some at low miles. The stupid gov bureaucracy tried to solve 1 tiny problem and created 100 other big problems and drive up the costs of the trucks.
So do I like the 3.0 light duties, absolutely and would love to run a bunch of them, but at the current state, will never ever happen. If it were not for the hauling we have to do, we would sell every single mid duty.
BTW, we have issues constantly with our off-road equipment that has DEF as well. The scumbags that dreamed this crap up, should be made to by pay for it and work on it.
UNCLE SAM, VEHICLE MANUFACTURERS, and BIG ENERGY, YALL are pathetic!!!!!
Thanks for sharing your experience
I bought a 2021 chevy crew cab Z71 4x4 rst standard bed 3.0 diesel. I paid 1k Xtra for the duramax. I get 34 mpg on the highway all day long. I have not had any mechanical issues & have no regrets. Love my truck
Yeah that diesel gets better than advertised MPG!
great video! i have had the chance to own both the 5.3 and the 3.0 on a z71 silverados. i have 25k miles on the diesel and still puts a smile on my face when driving, towing my boat (5500 lbs ) is no problem staying at 65mph uphill, and still getting good mpgs.
Thanks for sharing your experience
thanks for this. You towing a bass boat? I'm towing a champ with a cateye 5.3 z71 right now. Was thinking of getting a new truck. What'd you think of the 5.3? I'm still on the fence. The 5.3 has been around forever and I would imagine working being able to work on it myself would save a great deal in maintenance.
@@Lorde360I just traded in my 3.0 for a 5.3 because of emissions problems. I loved the 3.0 in every way until it needed service. The engine can go into limp mode at any moment and only give you 250 miles until needing service. You can’t work on this engine yourself. The truck emissions codes can only be serviced by a dealership. I put 55k on my 3.0 before trading it in.
I have a 2019 Yukon XL 5.3 V8 with 4wd and tow package 3.42 axle ratio. I consistently get 23-25 mpg on my highway trips. 27.4 mpg was my best. I've driven over 600 miles with 3 gals left. My speed was 70 mph most of the trip. Here's the kicker. It was in manual 5th gear so it never ran in the V4 mode. It locks out the AFM if you use fifth gear. Rpm is 2,200 at 70 mph. The engine never switches back and forth between V4-V8. I drive it all the time in 5th gear. City and highway. I'm trying to eliminate excess wear on the hydraulic lifters.
Yeah those lifters can be problematic. Thanks for sharing
Good video comparison. I just purchased a 2020 GMC Sierra with a 3.0. Have only had it for 1500 miles. So far, I love the truck. I got 29.82 mpg driving back home from a 300-mile trip. I was really pleased. I'm a seasoned diesel owner. Two previous 6.6 Duramax Silverado's. I loved them, but diesels can have problems as they all can. The diesel problems usually happen in the exhaust which may be expensive. I purchased a warranty that covers the ruck for 5 years. Crossing my fingers. I'm hoping it will be a reliable truck for me.
Yeah the emissions stuff is a concern for me as well
In this case ya gotta go diesel! That 3.0 Dmax is a spectacular and super reliable diesel engine that gets great mpgs! My 3.0 out tows my 6.4 Hemi gasser and gets 5 more mpgs towing and 13 more empty! Oil changes on my 3.0 Dmax are $50 less than my 6.4 Hemi too! The 5.3 will eat the cam and lifters up! Stay away from the gasser!
I totally agree! Thanks for watching!
Diesel fuel is over $6 a gallon in Cali 🤨
I have been driving a 2021 Silverado LT Crew Cab with the 3.0 Duramax for almost 2 years. With rear wheel drive, it's rated at 33 highway. I live in California and there is much elevation change in most trips. I regularly get 30-33 highway when driving around 70 and smooth technique.
I have one of my trip odometers still running at over 18K miles, with my overall average at 26.2. Most of my driving is around town with regular freeway trips also. That's spectacular, considering that I make a lot of short trips and idle with the A/C on a lot in warmer weather. The thing that wasn't mentioned in this test, is that this 3 liter 6 cyl. diesel will waste a 5.3 at the stoplights (0-60). I've kept up with Dodge hemis and 6.2 equipped pickups.
It will also keep up with or outrun the Ecoboost Fords that are known for good acceleration. I'm timing my truck in the mid to high sixes in the 0-60. What a fun and at the same time, economical truck!
Thanks for sharing your experience
From a personal experience, GMC 5.3l made 130k mi and need engine replacement (valve lifter spring broke and damage everything) . So far I have 50k mi on GMC 3.0 diesel with no problem. I drive 50/50 city/highway and my average gas mileage was 14 on a diesel it’s 24
Towing my trailer with car : gas 10 mpg diesel 18 mpg going 85mph
I vote diesel.
Thanks for sharing your experience. Good to hear a perspective of someone who has owned both
I take my dog to work and keep the vehicle running at job site meetings with Doberman sleeping in the back.
The Diesel has heavy duty everything and doesn't burn as much fuel idling. I have PPV Tahoe which is fantastic for this condition but like switch to 3.0 Suburban with nice ride quality.
Yeah this would be a nice vehicle for your situation
I towed a donzi 22 classic up to Atlanta and then out to San Diego from naples fl. Over 6000 miles round trip. I averaged 21.9 mpg. I used approx 4 gallons of def. My gas 5.3 got 14 mpg towing the same boat.
Good to hear about your experience! 3.0L Diesel FTW!
I put a titan 52 gal tank in my 2500hd San Fran to Tampa stopped for diesel 3 times LOVE IT !
Why do they burn so much def towing. It’s disproportionate to the mpg drop
Good job. Don't forget the ~$1,500 cost to replace the timing belt in the 3.0 at 150k miles. Regardless, I have the 3.0 and bought it after owning the 2.8L minimax in my Canyon in 2017. Still own it too.
Any issues with your 3.0?
@@Myksgarage No, just 4k miles on it. Will start towing the boat in a few weeks; so, that should provide more info.
I love my 21 3.0 diesel 1500 25k miles of towing and no issues at all truck Outperform’s my 2019 5.3 on every aspect mpg and power.
Good to hear your experience! Thanks for sharing
I was on the fence for a long time but eventually the trim I selected (Tahoe Z71) dictated the gas engine. I chose the 6.2L for towing needs over the 5.3L. Based on miles driven per year, fuel cost differential (Premium vs Diesel), DEF charges and the higher cost of two oil changes a year, the savings was not significant enough for me to go with the Diesel though I think its a great engine. I just wish they could have fitted the 3.0L in the Z71 Tahoe.
Thanks for sharing your experience, it's nice there are some great engine options!
The ultimate would have been the Z71 w the Diesel imho. But, ultimately the Diesel won out for us.
Yeah unfortunately the 3.0 is to long for the tahoe z71
I decided it was better to have the mpg, and one can always modify a regular Tahoe to be more like the Z71.
With emissions on the diesel right now I wouldn't buy either.
Another cost to factor in against the diesel is the fuel filters. In all of my diesels (6.7 liter Cummins, 3.0 eco diesel) you change the fuel filter every two oil changes or around 10K miles. That won't stop me from opting for the diesel. The main pro for the diesel option to me is fuel-ups are few and far between. Thanks for the video!
Good point
GM recommends changing the fuel filter at 30,000 miles on their 3.0 diesel.
@@josephharvey5742 Ram recommends fuel filter change at 30,000 miles also
Only 1 filter to change on this engine vs 2 on the 6.7 Cummins. And the filter is fairly inexpensive and it’s even easier to change than on a Ram it appears.
@@tylerkraemer I hope so because I bought a '23 YukonXL Diesel. Loving the mileage. Getting a solid 19-20 around town and 27-28 on the highway loaded to the gills with 4 people and enough luggage that it almost doesn't fit with the 3rd row folded down. Best mileage I've got is 27.2 mpg over 450 miles, 36 mpg over 50 miles, and 43.5 mpg over a 25 mile stint. This is with a vehicle that just rolled over 4k miles. It had less than 1k miles before the trip. Couldn't be happier.
Less trips to the pump is a major plus imo. I came to a Yukon Denali from a model x where I never went to the pump.
Gotta love those Teslas!!
Owning both... Just get the 10 speed transmission. Both engines are great. The 3.0 is a great option. Remember diesel engines will rotate less rpm to generate the same energy so the components on diesel’s generally last longer.
Good point!
This is what I needed to learn from you about this Duramax Diesel Thank you
👍
Thank you sir. I am considering a diesel engine for the first time and you’ve given me some valuable insight 🙏🏽
Thank you, best of luck!
Great breakdown. I have the 2023 Yukon Denali with this engine. You forgot to emphasize the range. I recently came back from a trip and I got 575 miles off of one fill up. Bad thing is I’m dealing with Stabilitrack issues now 😂. I think it might be due to bad biodiesel after sitting too long since it’s not my daily driver. So thanks for the fuel filter video too, going to try that.
Thanks for sharing your experience!
Great advice. I’m a 6.2 V8 man for pulling my camper, I’ve had several diesel dating back to 1982, fords and Chevy and the converted Oldsmobile diesel
That 6.2L is a nice engine!
I own a 2015 Tahoe with the 5.3 L V8. At 92,000 Miles, the lifters on the AFM cylinders failed and we needed a block. This is a common issue on this motor. At that mileage, the injectors also need to be replaced for about $1K. The car had an extended warranty, still cost me about $4,000 to fix and the shop had my Tahoe for 4 months. I like the diesel since it is a tried-and-true design in trucks, but all the emission controls worry me about longevity, I am also concerned with costly diesel repairs. I believe this would be a better motor with the EGR, DPF, DEF, and SCR removed. The 3.0L Duramax has a longer warranty
Yeah those are all good points
Gas is $2.99 diesel $4.99 here. Not saving money with our 3.0 suburban but I don't have to worry about collapsed lifters.
Yes good point
Exactly!!! Is it true that lifters are not a problem with diesel?
Thank you for this comparison . I live in rural Saskatchewan Canada and have had diesel engines in my life forever. I currently own a2020 Ram longhorn EX Crew 4x4 Eco Diesel which is my second one after a 2016 . We also own a 2020 lexus RX 450 H . Most of our trips are 15 to 200 miles. The Ram always exceeded the Lexus in fuel economy 32 to 26 MPG US gal while weighing nearly twice as much We used to be always about 5 % cheaper for diesel until this last year. I really don’t understand why diesel is more expensive now other than government intervention and ??? . I’m sad to see that Ram is discontinuing the 3.0 diesel . I think this big shift to electric is way ahead of infrastructure and battery technology. Government knows best ,RIGHT !!!
Yeah unfortunately i think these diesels are in their way out
here in canada , they all blow-up. They dont like to run cold
Thank you for the break down. I am excited to get the diesel.
Thanks for watching!
In Houston gas is @2.89
And diesel is @4.29
Big difference
My 2022 5.3 with the 10 speed Sierra gets me @25 miles per gallon going 75-80mph
My father in law 2021 Denali 3.0 diesel gets him @29 miles per gallon not a big difference
Where the diesel does shine is when towing a 7k trailer compared to mine
Thanks for sharing!
All the roads in Houston must be going downhill, everyone I know with the 5.3 including my son average 22 or less going 75 mph on the interstate.
What about regular maintenance? Oil change and filters? Cost/frequency?
I made another video that goes through those items
th-cam.com/video/Vnv-6j-TVbs/w-d-xo.htmlsi=y2_Qq4AVtue_Vmu4
When buying my 2024 1500 elevation, I initially wanted the 5.3 V8. I was picky of what color, package, and interior I wanted. The only engine options that was out there for what I wanted was the 3.0 diesel. I was like hey I’ll just get it and sacrifice my V8 option. And I’m glad I did! Great mpg and the fuel costs around my area isn’t as high for diesel. I’m actually saving $$$ with fewer fill ups.
Good feedback
Myks, excellent cost breakdown. I did the same research and finally got myself a 2023 GMC Sierra 1500 Denali with a 3.0 Duramax. To my luck, I've had two check engine lights at 600 and 800 miles. This is my first diesel and GM vehicle. Hopefully, with the parts replacement, I can get as good a reliability/longevity results as others have stated. To those that want to know what code came up, it was a P0402 with an Emissions System alert on the GMC application/Diagnostics txt.
Thanks for sharing your experience!
Emissions systems are literally the worst things on these.
I have put 94,000 miles on my 21 Silverado inline 6. Engine has been flawless. Def tank had to be replaced after 6 different trips to the dealer. Of course not in stock so had to wait almost 2 months with a loaner. Now the Catalitic Converter is out according to dealership. $1,400 not covered in my extended warranty. I'm averaging 24 mpg with several hundred lbs. Of tools on board. Most of those miles are going 82 mph. Still like the truck just wish I could delete the emissions system. Then it would be a GREAT truck.
Good to hear from someone with some real miles on their truck!
Having said that, I put 406,000 miles on my 06 Silverado 5.3 and it never needed major work. I plan to put 250K on this one. Hopefully...
@@jdvid007 how is u 3.0 now ? Did u fixed the problem ? Any issue? How many miles now ? I have 5.7 v8 2010 and want buy 3.0 Duramax but will be my first diesel, I am little scared
I consistently get 30mpg on mine. 2022 GMC Sierra SLT 4×4 3.0 Turbo Duramax
Thats soild!!
The price difference comes in on the extra maintenance cost to own a diesel. The sad truth is it just cost way more to maintain a diesel. I’m a diesel mechanic and have always owned hd trucks with diesel engines. For the first time in my life I bought a half ton gasser 2023 rst with a 5.3. I’ve seen 25.4 mpg best on 50 mile highway runs and 23 average highway. Def is ruining diesel engine and destroying very expensive injectors it’s not worth it unless you are towing heavy at this day and age. They just don’t make them like the 12v Cummins anymore
Thanks for sharing your experience
But doesn’t the V8 have a lifter problem? I’m thinking of buying a V8 Yukon and just learned that this is destroying engines.
I test drove a new 2024 GMC with the new V8 and then I test drove a used 2022 GMC with the 3.0 LM2 it was night and day in terms of the drive experience.
I chose the diesel .
Good feedback, thanks for sharing
When the car is out of warranty you can delete the diesel exhaust fluid and it's a lot cheaper to buy it at the pumps when available
Good tips!
I am in the 1 ton, ir F350 6.7 powerstroke world, but yiu should factor in cost if maintenance between gas and diesel to give more context of owning each. Great capture of metrics in just fuel and mpg data.
Yeah I need to do that next. Thanks for watching!
I also do fuel efficiency comparisons with my 2021 Silverado 3.0 and my wifes 2021 Tahoe 5.3. Both are 4x4 Z71 models. I normally calculate it by each gas tank, and I calculate it by the mile. In my area, my truck at best was 17 cents a mile, and my wifes Tahoe was 22 cents a mile. Of course, understanding that the Tahoe most likely weighs 800 lbs or more than the truck. Although gas and diesel are getting cheaper, the average cost will get better. I still feel the diesel is the better choice for fuel efficiency.
Thanks for sharing
Thanks for the helpful breakdown. 👍👍
Thanks for watching
Good simple comparison. Thanks
Thanks for watching
My brother-in-law went from the 6.6 diesel to 6.2 gas. Then to the 5.3 and the one he liked best was 6.2 gas.
The 6.2 is a good engine
Then he wasn't towing like I do 99% of the time, my 6.6 Duramax will kill the gasser in every way. Duramax is KING.
Curious if GM is going to change to the LZ0 new 3.0 duramax in the Yukon, Tahoe and Escalade like they did in the Silverado and the sierra that’s now 305 hp and 495 ftlbs instead of this one with 277 hp and 460 ftlbs
Yeah it will be interesting to see when that change happens
Yes. They are for 2025.
I have a 2021 Silverado 1500 with the 3.0. I absolutely love the thing. My favorite powertrain I've ever had. also with the 5.3 STILL has that stupid lifter dropping issues with the AFM junk. GM V8s are so bad with that stuff on them.
Yeah that's a good point! The 3.0l is awesome. And now with the new LZ0 coming out it will be even better!
I second that. I think the 3.0 and the 10 speed is the best powertrain ever in a half ton suv/truck.
@@Myksgaragewhat’s the LZO
I prefer the simplicity of a gas. Less chance of issues for me. My truck pulls my 8500 lb boat no sweat. But to each their own.
Yes
Which gas engine do you have??
How do the numbers hold up when you factor in the cost of oil changes and general maintenance?
I'll do a video on this shortly
Thank you for the comparison. I want he Z71, but I want the Diesel engine. The High Country, doesn’t have black seats,and I don’t like the selection. Now I have to figure out what model I want with the diesel engine.
Good luck with your choice!
I also have a silverado RST 3.0. I get 6.1 litres per 100 kilometers on the hwy.
Very satisfied with it. I believe that's about 35 mpg. I get 1200km or 745mi.
Gerry
That is very good!! Thanks for sharing
I would add to your cost comparison that there is about a $90 difference in the cost of the oil change. The diesel is just more expensive. Also, don’t forget the cost of the fuel filter change as well. I own both a Tahoe with the 3.0l diesel and a Silverado 1500 with the 5.3l. Hands down the better powertrain is the 3.0l diesel for performance and the torque, but I think the cost of ownership and fueling is pretty similar.
Good point!
Most bs I see all the time. Most sissy 5.3 or 6.2 gas go 3000 miles for oil change and the diesel is at least 7500 miles or up to 10000 miles if you don’t tow a lot. Unless you’re moronic and have dealers change it for you and they gouge you. I buy DEF in 55 gallon drums and save a ton compared to the jugs of over priced stuff at gas stations. Also the stuff in drums is a good quality DEF. My 2500weighs 9000 lbs loaded and can get regularly 20 mpg. My friend has same truck gas best he’s ever done was 12 mpg. Keep drinking the kool-Aid on gas republican fat cat oil ceo appreciate their massive profits.
@@CdpOper I have ran gas and diesel with diesel for the last 20 years, as long as I tow which is 99% of the time, I will never go back to gas, the day I don't tow anymore, then gas will be my only choice.
I went from a 6.2 1500 to a 3.0 1500 the mpg is about 25% better and diesel costs less than unleaded here. It's definitely a lot less than premium which the 6.2 recommends. Diesel for me is the way to go
Thanks for sharing your experience!
Biggest problem for me was that the exhaust system isn't included in any extended warranty regardless of the company. After 36,000 miles, you're on your own. There's just too much $$$ at risk for some random exhaust issue. Many common issues run in the thousands of dollars to fix. Love the engine, but hate the exhaust requirements.
Yeah that is a problem!
Delete
Federal law covers you for 8 years/ 80K for emissions. Unless I'm missing something.
@@ladin425 Not for DEF components. They are considered part of the 24,000 mile requirement. It also states that in the GM warranty.
Emission control and emission related parts are covered for the first 2 years or 24,000 miles of vehicle use (whichever first occurs); and • Specified major emission control components are covered for the first 8 years or 80,000 miles of vehicle use (whichever first occurs).
From the GM Warranty Book.
Light Duty Car or Truck
Emissions-related components are warranted for 2 years of 24,000 miles, whichever comes first
Select emissions-related components are warranted for 8 years or 80,000 miles, whichever comes first. Covered components include: catalytic converters, engine control module, transmission control module and other diagnostic-emissions-critical electronic control units
The list of "select" components covered for 8/80,000 doesn't include most of the major problem prone parts of the DEF system.
Things not covered after the bumper to bumper: Particulate filter, DEF sensors, DEF tank, DEF heater, etc.
Unfortunately, the emission control systems on modern diesels are your reason not to buy ome.
Every time I use a gas vehicle I am upset how many trips to refuel I have to make. When I drive my diesel vehicle, I have to think, when was the last time I filled this thing up.
Good point!
More range, more longevity, saving $4000 over 20 years, and much more at a more reasonable Diesel price differential. Very interesting : )
Thanks for your comment
His experience with resale reflects what I've seen with my diesel trucks. So, he should really adjust his cost numbers because the higher price one pays for a diesel truck is returned in the resale value.
Good point
Great video, now compare how much service cost (oil change) for each vehicle. I think you will find the diesel is much more expensive.
Yes, I will make a service video
Yeah exactly, I appreciate your efforts in this video. However, you also need to calculate cost of routine maintenance, which as a former diesel owner is almost double the V8.
My son has had two GM vehicles with the 3.0 litre diesel and he averaged way better than posted mileage. He pulls heavy trailers and it hardly affected his mileage. Average over 15000 kilometers was 8.2 liters per 100 kilometers or 28 mpg. Again that includes pulling trailers. A 5.3 liter will never be that consistent.
Thanks for sharing some real world experiences
Be cool if Fuel filters, and oil change difference cost was factored. I know we can't cover "All" cost. But that seemed a bit standard to add. Thank for putting this together, great watch.
I did do a maintenance comparison in this video:
th-cam.com/video/Vnv-6j-TVbs/w-d-xo.html
What do you think about for city driving? Which one would be better, say to drive for Limousine?
Diesel
Diesel prices went crazy
Heck yes!
I have had my 3.0 Silverado for just over a year and love it. I have gotten just over 38 mpg on a 50 mile average but was actively trying to see how good I could get it. Normal interstate is 28-33 mpg. If you don't take trips of 50-70 miles at least a couple of times a month the diesel is not for you it must be driven on decent trips every so often to allow the DEF to do its job. So if this is for trips to the store it is not for you. One calculation you failed to show is value when you trade it in. Normally diesel motors hold a better price so that 900 at the start will be paid back unless the motor turns out to be a dud.
Thanks for sharing your experience
For the second 100K on the gas engine you forgot the tune-up charge. Appreciate your presentation.
Yeah I'll need to do a maintenance comparison next
I watched another video on the engine and apparently there is an internal belt for driving the oil pump that needs to be replaced every 150K and the transmission has to be pulled to do that. Seems like a pretty good engine though.
I like your video! As someone has already mentioned you need to factor in maintenance costs. I'm on the fence and can't decide for a 1500 truck. The one thing keeping me away from going with the diesel is the concern with fuel quality. If you're not careful you can go to a quality fuel station and still end up with too much water. From what I've been told it is best to (mostly) go to fuel stations frequented by diesel trucks.
I think the maintenance costs are very close, both will need an oil change every 5-7k miles, and the diesel will need the fuel filter more frequently.
I work in the oil industry and I'll tell you that is a major issue with gas as well. Biggest thing is to avoid filling from stations when their tanks are low.
@@realmil733 thanks for the reply. I’ve heard of that before but just not as much as with diesel. But I’d believe it!
@@realmil733 Thanks for the tip but there seems no way to know this unless I guess you work at that station?
@@tjsullivan4793 if you’re that worried about it they know how much fuel they have in those tanks and yes it’s in gasoline as well so 🤷♂️
I think the only thing I would have changed is to depreciate the cost of the diesel over it's expected life span. The savings in operating costs would be a little more in favour of the 3.0
Yeah good point
Wasn’t sure if you factor in cost of fuel filter and cost for oil changes also the 100k belt replacement in the rear of the engine which on average is $1200 for that service by dealership
The oil belt change has an interval of 150k miles, but I didn't factor that or other maintenance into the equation.
It’s 150k belt actually.
I'd recommend the second gen variant of this motor. On this version you have remove the transmission to change the timing chain/belt @ 150k miles
I believe the 2nd gen has the same requirement, and it’s not available until 2025 model year
Well those numbers seem realistic to my experience of owning a 3.0 but the biggest difference is I believe is the commuter everyday driving. I get 23 or better mpg everyday driving 20/30 miles a day. I’ve never gotten more the 15 mpg from a gm 5.3 in that regard. Plus this bad boy gets 16 mpg towing our Rv.
Thanks for sharing your experience
What's the oil change and fuel filter change cost in comparison to the 5.3L? That should be added into your comparison to be more accurate.
Here's the maintenance video I made
th-cam.com/video/Vnv-6j-TVbs/w-d-xo.htmlsi=xk7DVCOLsgObhACy
@@Myksgarage thanks! I hadn't seen that video before I commented so I'm glad you shared it. I'm so interested in the 3.0L, and even if if it comes out even or slightly more for the cost of ownership, I'll still select it over the other options. Take care and Merry Christmas!
Do you have to buy def fluid for the diesel? That needs to be figured into the mpg. What about the coast of belt maintenance on the diesel?
Yes the DEF was figured into the cost
Factor in Oil change cost and you might see a significant difference between the gas and diesel Oil change and filter costs.
Yeah I need to figure those costs as well
One thing you didn’t talk about that makes a big difference for me is; time and frustration.
The Yukon XL has a 28 gallon fuel tank. Using your math (and assuming every tank was run empty before fueling) the 5.3 would need to refuel 188 times. The 3.0 would refuel 133 times. That’s 55 less trips to the pump.
If the average fill up takes 7 minutes, that’s an extra 6.4 hours spent at the pump over 100k miles.
Time is money in my business.
Plus the frustration of gas burners always pulling up and blocking the only diesel pump when there are 5 open gas pumps. And yes; I will call you out for it and make sure you know how inconsiderate you are of other people!
The fewer times I stop, the less frustration I have in my life…
I never considered that, good point!
Great video. I am a big fan of of the diesel and the driving characteristics. Since you added the extra cost of the engine and DEF though, I would have added the extra cost of oil changes as well to your calcs. I don't know the 3.0l Duramax oil requirements, but I know for my wife's Cayenne diesel the oil is about $8/qt...roughly twice as much per quart plus it takes more oil than an equivalent gas engine. That alone would probably add a few thousand more dollars to the cost over 100,000 miles. That's not even touching the potential cost of expensive diesel emission systems if they fail. With that said, I still prefer the diesel.
Good point on the increased cost of the oil!
By me right now diesel is $4.00 while gas is $4.20... Never thought I'd see the day when gas is more expensive
Yeah it's definitely nice having a diesel right now!
For me I am currently leasing a 2020 Silverado with a Turbo-4 in it. Mechanical wise the engine in my truck as been trouble free so far but it also barely has any miles on it. Any problems I have had have mainly been related to sensors and anything computer related. Luckily enough it was all stuff that had a recall and was replaced for free under warranty. As much as I like the 5.3 it is mainly the OLD 3rd Gen 5.3 in my previous 2004 Silverado that I liked because they were bulletproof. The later models especially the current ones are not good. I don't like the thought of my trucks engine potentially eating its' lifters while I'm just driving to the store or going to a friends house.
I have one more year of my lease to go before it is up and if I decide to go with something different over staying with what I already have I was considering the 3.0 Duramax diesel. From what info I have seen about the 3.0 it has been relatively trouble free besides a hard start issue some people were originally having and the worry about the oil belt. Both of which have been fixed for the 2023 model year as GM has found a solution for the hard start problem and they reassessed the dependability of the oil belt and have upped its' mileage for when it needs changing.
The DEF is usually not an issue because it's not filled as frequently as your diesel fuel is from what I know. I am also not worried about oil changes as I am already in the habit of buying the best oil and filter I can get my hands on. I can afford expensive oil and filters. I can't afford expensive engine problems if one were to happen due to junk oil. From what I've seen I think the 3.0 also comes standard with a block heater for winter use which is also nice. :)
You make some good points, thanks for sharing your perspective
@@Myksgarage You are welcome. I have always wanted a diesel pickup in the past but diesels always only ever came in big pickups made for heavy pulling. So unless you moved around large equipment or big loads you don't need a 3500.
Now they offer a diesel in the standard 1500 line of trucks that offers good power and towing ability. I love my Turbo-4 but if I can switch to something that is less likely to have issues down the line when miles are added on I'll go that route.
Getting my hands on a good diesel in the future that isn't a giant v8 is a big plus. It's even nicer knowing that GM was smart to go with an inline-6 over making it into some compact v6 model.
Also, as another person pointed out in a video about the 3.0, the turbo on it is liquid cooled. So it uses the engine coolant to keep temps within spec. The turbo on it should be far more reliable on it than a standard turbo. :)
I hear good things about the little 2.7 4cyl turbo base motor. On paper it has more torque than 5.3 and fuel mileage is 22mpg hwy.
@@larryj8924 So far it has been great. The only actual issues that I have had were all related to sensors and computer based junk. But the problems I had ended up having a recall on them so the parts were replaced for free under warranty. When I first got the truck we had the bed spray-lined before I hauled anything in it as part of the lease deal.
After the spray-lining was done we went and got a large enough load of decomposing wood chips to make it squat a little and it hauled it just fine. There was no struggling or having a hard time getting up to speed. It drove as if there was nothing in it. Since mine is a 2020 it's rated for being able to pull 7,500lbs. I think newer model 2.7's have a higher towing capacity.
As for fuel mileage, I tend to average about 16'ish mpg. My town is nothing but stop signs, intersections and hills. So the driving conditions aren't the best for fuel mileage. I still have one year left to my lease so from now to then there will probably be something else out by that time.
$2.00 difference between diesel and gas in nj now ..i still love my diesel
Yeah that's the only problem I see....
Diesel was always way cheaper than gas, until I bought my first diesel.
what about the oil changes, whats the difference?thanks.
Here's the video on that:
th-cam.com/video/Vnv-6j-TVbs/w-d-xo.htmlsi=N9MptPDHT2DzGeZA
I’m still on fence even thought I have a 5.3 V8 already. I drive about 170 miles per day,90% of highway and never tow. Daily fuel cost is $22/day depends on I’ll go for E10 or pure gas on the day. I’ve learnt that you will pay less on fuel but you have to add up things like DEF,more expensive maintenance,insurance and even parts whenever you have to fix it. Hopefully someone could bring these all up to give us a more detailed picture
Thanks for watching
ive thought about the difference between gas vs diesel, it really comes down to cost of fuel in your area and if your towing a majority of the time. yes you will get more mpg per gallon of diesel vs gas but the cost is what kills any gains. At the time when i did this comparison, gas was low $4 and Diesel was around $6. i compared a GMC Sierra 5.3 to the 3.0 and the 5.3 is what i would choose. Diesel is almost $2 more then gas here in PA, for the same price of filling up a tank of Diesel about $125 for 21gallons, filling up the gas was about $85 for 21gallons, with the difference in cost, i could us that remaining $40 and buy nearly another 9-10gallons of gas. This would give me the ability to driver more miles in the 5.3 than the 3.0 while spending the same amount of money at the pump. con would be having to fill up more for gas but your going farther for the same $. Take into consideration, theres also more costs associated with Diesel - Def Fluid and most people forget the diesel engine costs more then the 5.3, but less then the 6.2.
as i said, it comes down to personal preference, for me and what i would use a truck for, it wouldnt make sense to go with the diesel.
Yeah at $2/gallon difference, it doesn't make sense to go with the diesel
Great video. Thanks. Looking at a Silverado diesel
Good choice!
Put a Banks Pedal Monster on the 3.0 liter Diesel.. amazing! At 53,000 miles my avg mpg is 27.6 and 40 MPG is the highest.
That's cool! I need to look into that!
The oil pump drive belt at the rear of the engine requires the transmission to be removed to replace it every 150,000 miles
The cost of doing this is approximately USD$1300 (parts and labour)
That's not bad
I currently own a 2022 Silverado ZR2 (6.2L gas). Love the power 420 HP, like the V8 sound and it's a nice optioned loaded truck for sure. BUT,, I have towed a dual axle enclosed trailer at 70-75 with about 7k load and get 10mpg. I also tow a small toy hauler dual axle approx same weight and get less than 10mpg at same speed due to wind drag. Long story short I have ordered the 3.0 with max tow package due to a couple times headed west, didn't think I would make it to next gas station. Friend tows with LM2 about same weight and they are not even comparable, ZR2 sucking vapors and LM2 wondering why we stopped again !
That is very interesting!
Do these vehicles have to go through a regen process? I work for a fire department and our new engine has to sit outside sometimes and idle at high RPMs. I was told it has something to do with emissions.
Yes they do, in about 8,000 miles so far, it has only asked me to do it once. th-cam.com/video/vxZMkbfv6r8/w-d-xo.html
A great comparison video . . . have you ever checked the MPG of your vehicle with a calculator ? ( dividing it yourself ) I have found on some cars, that the stated MPG in the cars computer is a little different when I do the math myself.
I haven't, I'll have to do that
@@Myksgarage See what you get, I haven't checked my new SUV yet - the newer vehicles might be better, now.
Ty, so maybe a non lifted SLT or Denali on Michelin zLtx could see 30 mpg ??
Probably, check out my latest mpg video
th-cam.com/video/f5hzLLgDNw8/w-d-xo.html
At 4200 ft elevation could be one of the reasons for your better than stated mpg with the turbo diesel.
True....
The biggest difference is oil changes cost, about double. And fuel filters, which is significant.
Which is weird because this diesel takes less oil than the 5.3L V8 Gas engine
@@Myksgarage
I just looked at another review. Something weird is going on, thought he said it was more oil on the 3.0….
You mean the diesel costs more for oil changes?
Gas is quite high in your area. 85 octane gas in western Colorado is $3.15 a gallon and diesel is $5.25 a gallon. I can easily beat the 19 mpg on my 5.3 V8. I average about 23 on the highway and with DOD disabled. Resale value is a top priority and in my area the 5.3 will win when it comes to reliability as it has been in service over 20 yrs. People will shy away from a diesel with the cost being over $2.00 a gallon more.
Thanks for sharing your experience
About the cost to replace the wet belt on the 3.0 ? Transmission need to be removed to do the job, Also the cost of engine oil for the diesel is higher, fuel filter.
All true
I get a kick out of seeing this. Even though I've had my 3.0 GMC for about 1.5 yrs and 35,000 miles, I still make the comparison to my wifes Tahoe with the 5.3. My experience overall has been similar to the comparisons you make, with the 3.0 working out a little better in terms of straight up fuel efficiency.
However, I think for some, the gap may be little closer than what you're showing. Of course, this is largely driven by (a) general fuel prices and (b) whether or not Premium is used. The other couple things to consider is (1) Fuel filters. Going to replace those every 20-25K miles on the 3.0. Can do it yourself for less than $100. Shops want double that.
IF you're towing most of the time, the fuel efficiency on the 3.0 drops off considerably. In fact, it's within 1 or 2 MPG to the 5.3 hauling the same load (or worse, the same as my former Tundra). BUT, the amount of effort the 3.0 puts towards hauling that same load feels much less. I consider that to be valuable - but hard to put a calculated $ on.
In general... even if its a wash, I also get a kick out of being able to drive 700 miles without refueling, regardless of whether I stop or not.
So which do you prefer?
@@Myksgarage For now, I'm still liking the diesel better. My only reservation is for the unknown. Sure, there's a few folks out there with 100K plus miles already... but it's such a small sampling that it's tough to really get a full view of how well the LM2 or LZO is going to hold up. With the 5.3 (or most any LS based platform), I know what it is, what it isn't, what it will/won't do, how to resolve things, etc. The other thing is... and it's got nothing to do with performance, is for most - stepping out of the norm for fueling. For so many, making that transition from gas to diesel could result in a fairly pricey mistake. They really have to be deliberate about grabbing that diesel nozzle in lieu of 87 or whatever... habits!
Hey what type off deaf you put in your diesel
The cheap superTech Walmart brand
Interesting review. One thing I'm interested in is inspection/repair costs. Any ideas on that?
I will have to do some more research
Also maintenance on fuel filter costs and the oil cost more ,,, plus at 100,000 miles the oil pump belt needs replacing at approximately 1200.00-1500.00 dollars have to remove transmission to replace,,, add that to the next 100,000 miles !!!
Fuel filters are cheap, and you also have to replace the fuel filter in a gas vehicle as well. Oil pump belt has a service life of around 150,000 miles
the big factor left out is the 150,000 mile maintenance of the diesel. all things being equal, the 150k chain maintenance may cancel out all savings in fuel cost if not more. i wuuld love a baby diesel, but im not buying now and hopefully when i do those factors will levelize more.
This video was simply a fuel cost comparison, I did another video on the maintenance costs
Unfortunately I got one of the bad lifter problem engine. Both the 5.3 and the 6.2 engines have the lifter problem. And the crappy way GM addressed the problem by just replacing one bank of lifters at a time, was completely inadequate. After the third bank of lifters were replaced before the vehicle had 18,000 miles on it .
Does the desiel have any lifter problems?
I'm not sure if the diesel is susceptible to this problem
You didn’t calculate service cost between the two. Like oil changes which are more for diesel than gas, additives to fuel on diesel for winter and summer.
Yeah, this was just mpg comparison
You didn't talk about the costs associated with oil changes and maintenance
Its about the same on either vehicle
Diesel gas prices are usually $1.50-$2.00 higher than gas prices here in West Tennessee
What's interesting is in my area right now Diesel is only 25 cents more than regular unleaded
@@Myksgarage that’s when prices are generally higher all over the country. At the moment diesel is around $0.70-.80 cents higher at this time.
You forgot the cost of changing the OIL PUMP located inside the crankcase. With a 4x4 like I have they have to take the front end apart in order to drop the oil pan to get to the pump. BIG BUCKS in labor not to mention the cost of the pump and the alignment of the front end when it is finished. Also, the 3.0 takes SPECIAL OIL and every oil change which I do myself,
costs $93.00 for the filter and oil from Amazon.
I covered those costs in this video
th-cam.com/video/Vnv-6j-TVbs/w-d-xo.htmlsi=HmOwyjEfylXLXpHN
Rob Sea, yes I do have a 1500 AT4 with the 3L duromax
Nice!!
Thank you for doing this video. I’ve been wondering about this and hadn’t have the time to sit and figure it out. My question is if you aren’t towing and you live at sea level is it still overall better to buy a diesel for fuel economy/$ and resale?
It's tough to say, the diesel will get better mileage at sea level vs elevation. Really just your preference
@@MyksgarageDoes the diesel have the lifter problem s?
