Great video, however, after running the 5.3 dog engine for several years and now on my 2nd 3.0 Duramax. I’ll take the little engine that could, and does outperform that 5.3 in absolutely every way. It’s a solid little inline 6 that keeps putting a smile on my face every time I tow. Run a trailer behind that 5.3 and the little Duramax too and without question, that 5.3 is a dog that struggles. And doing the same comparison here while towing, without question you are absolutely money ahead with the little engine that does outperform any engine in any 1/2 ton truck. Ford, Chevy or Dodge. This little 3.0 is a top dog, fuel efficient beast of any 1/2 ton from any manufacturer in production. Bar none. GM hit the wholly grail on this engine/ transmission combination period.

What's the range on a full tank? That's the benchmark for me. I live in the Yukon Territory in Canada with many, many kms/miles between gas stations. I have a 6.2 XL Denali and can get the thick end of 1000kms on a full tank.

Diesel injectors don't last forever either, especially with the subpar factory filtration that the Big 3 keep purposely cheaping out on. GDI injectors at $250 a set is nothing compared to six diesel injectors costing 13-1500 bucks. I prefer to leave the daily driving to my 5.3 Chevy for the cheap maintenance, and the heavy pulling to my 6.7 Cummins.

Comparing owning a 5.7 L I force gas engine to my 2022 L5P 6.6 L duramax at toyota dealership 160$ far oil change and tire rotation on the 5.7 gas at GM dealer it cost me 170$ far the 6.6 HD duramax oil and tire rotation so not a big difference at all . I also get close to 20 k miles on fuel filter love the diesel engine

I’ve had that quoted at the dealer for $1700 bucks. Not much more than a timing belt change. What’s 1700 after 150,000 miles on a $70k truck. This argument always cracks me up.

Lots of good information in this video . . . I'm thinking about buying a Yukon Denali in the next few months and I'm trying to decide which of the two engines to buy. I won't be using it for towing ( much ) and I have heard the same lifter problems in the V8 gas engines that you mentioned. The 3.0 would be fine for what I will use it for, but I'm concerned about how often the engine goes into "regen" mode ? I may have asked you already LOL - but, I drive mostly around town and I don't want to have to wait in a stores parking lot for the regen to stop before I can go in. I drove a new commercial vehicle about ten years ago, with a diesel engine and it did the regen at least once a day ( I traveled about 100 miles a day in it ) and it seemed to always be when I wanted to shut it off ( the mechanic at the shop said not to turn it off when it's doing it. Maybe they have changed in the past ten years. How often does yours go into regen mode and do you have to wait to turn it off like I have read others have said ? Keep making videos - I've learned a lot from the others.

@@chadmark88 Regen on the 3L Duramax is mostly passive and you will rarely notice when it happens. On average it will happen about once every 400miles, but there's no indication it's happening unless you look at your instant fuel economy readout. If it can't fully completely a regen, it will tell you on the dash to continue driving to complete the regen - that's the message that Myk saw at one point in 12K miles he's put on this rig. It for sure has gone through other regens for him, but again they happen in the background with no indication to the driver.

Diesel formulas change for the winter to minimize gelling at low temperatures. Results in worse fuel economy but better than having a dead engine. So I can see why that recommendation came about.

For Suburban, is the 3.0L more reliable than the 5.3 gas for long term?

Couple of things ya forget to mention: transfer case + radiator fluid + differentials f/r + oil. Na v8 engine calls for synthetic oil every 5k (recommended). However if you want to have those turbos to be happy on that diesel engine, you will need oil change every 3k. So all in all, overall maintenance is basically the same once you factor all the other costs.

Both engines are now 200k. Also it’s for an inspection not replacing it. Of course if they are already in there you might as well change it. Also I was told that if it breaks you will get an indication before you damage engine (mine is the LM2). GM is still testing belts and it is still exceeding what they thought so they moved it from 150k to 200k.

Don't buy a diesel unless you often tow heavy loads. Initial cost is more, fuel is more, maintenance is more, repairs are more, and you'll never make your money back in the fuel savings.
