I currently have a 2019 RST, 5.3, 8 speed. I'm trading it in the get the 10 speed, I had a ton of transmission problems with my old Silverado, not doing it with this one.

My problem is, I can't figure out what engine I want, 3.0 or 6.2.

 

6.2

Pro

- 420 hp [emoji41]

- Decent gas mileage

- Higher tow capability

Con

- Premium gas

- Towing gas mileage?

 

 

3.0

Pro

- Great gas mileage

- Good for towing

Con

I might miss the sound of a V-8.

Lower tow capability

Expensive in the shop once out of warranty.

 

I plan to buy a boat in the next couple yrs, do not tow much now. I plan to keep the truck for a long time.

 

Let me hear your opinions, thanks.

Yup. If ya can’t feed it, don’t breed it. Or something like that. ?   I don’t see much point in buying a performance engine and then running junk fuel through it. 11.5:1 compression. I don’t

Don't forget the price of DEF fluid, frequent fuel filter changes, and the higher price of fuel for the 3.0

Can’t beat the entertainment of the 6.2. But it is a thirsty MOFO. Currently at a lifetime economy of 14.1 MPG. Gonna see how gas prices are with the new leadership. Might wind up in a 3.0 by this tim

I have a 6.2L and love it to death, but after driving  my stepdads 2020 Sierra 5.3L with new 10 speed, I could see myself buying one because it does at times get “cumbersome” putting premium fuel in the 6.2L. I know it’s not required but if you want all the performance out of the truck, might as well put it in.

GM did a great job making the 5.3L a respectable performer compared to the older K2 trucks.  I was truly impressed how well the truck accelerated, handled, and towed when driving it. I came from 2 K2 5.3L and it’s night and day difference.  
The 5.3L with 10 spd should be considered and he is getting about 3 mpgs better than my truck

Good luck with your decision

I have the 5.3L and have wavered back and forth about getting the 6.2L or the 3.0L whenever I trade my 2019 in sometime in the next 1-2 years. I feel the same dilemma as you do, OP. 

 

On one hand, I love the fuel efficiency and the torque of the 3.0L. On the other hand, I love the sound of a V8, and the 6.2L is a beast. 

 

When I'm actually in the truck driving around in my usual driving, I find myself realizing that the 5.3L actually is a good fit for me. I think the 6.2L is something I just wish I had in specific moments (mainly accelerating for fun). I don't really tow, and I put about 8K miles on per year so MPG nor premium fuel is really a big issue for me. 

 

Suppose what I am saying is... stick with the 5.3L. You won't be buying an engine that is more costly to own (both 6.2L and 3.0L), and it really has a rock-solid performance history.

Unless you find a deal you can’t turn down, you might wanna wait too. Won’t be long before the 2022 refresh is seen and it might put a hold on your plans.

Dude, I was in the same boat some months ago.  Then I found the 2020 2500HD LT w/ the 6.6 gas.  I like it better than the 6.2 and takes regular gas.  The 6 speed is a def upgrade over the old 6 speed.  No clunking.  Smooth as silk.  Oh... and no cylinder deactivation.  No shut down at stop...  Iron block 400... whats not to love!

 

Like all the new models, the new 2500's are not without their issues.  However, I am so happy I got it over the 6.2 trail boss.

I've never done it because I am more than happy with the performance of my 5.3, but has anyone done a true comparison of a 5.3 running 87 octane vs one running 92 octane ?

 

Add an aftermarket CAI and exhaust and make all of the V-8 sound you want.

Once you have the 3.0 .. you'll not miss having the 6.2L 

 

Unless you are still into holeshots from red lights, there's just nothing compelling about the 6.2 compared to the 3.0.

 

I've owned both and will not look back at a gas gulper like the 6.2.  We're talking 40% better mileage in most cases IME. And, the 3.0 goes when you need it to.

 

Test drive both, you'll see.

You’re making me regret my recent purchase. I didn’t drive the 3.0 as I’m a sucker for a big v8. This thing drinks like I do!

The 3.0l with the 10-speed is a fantastic combo.  Unless you are drag racing your truck and or really just like running a high-revving gas v8, the little Duramax is no-brainer in that truck.

LMAO ...  I've had 2 6.2's .. and couldnt take it anymore.  Bought the 3.0 without even driving it.  Same day, my brother bought the 6.2.

 

He quickly came to the realization he made a big mistake.  Best I ever saw on the 6.2 was 22 MPG on the 3.0, I hit 36!!!!

I guess I shouldn’t have judged it without driving it. I didn’t even consider it. I assumed it was a turd on the road haha. Baby D max. I’m gonna have to go take one out.

Take one out you’ll love it!
 

I had a 17’ 5.3 that I Traded for the 3.0. The 3.0 does have a slight exhaust sound when your driving. I’d say the sound is more noticeable while driving then outside.

 

 I thought I would miss that v8 sound as well however over the past month and half I haven’t missed it once. Towing wise I can still tow 8500lbs, only 500 less than my 17’ 5.3.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Blazer is all put back together. Another hard-won battle. The 4.3 is not easy to work on in such an archaic and narrow chassis originally designed for an inline 4.   My baffle issue is solved. I returned to the OG junkyard but was ready for a fight. The Blazer I had picked from was stacked on another vehicle so I had no idea how the heck I was going to get myself to working height to pull the front end apart. I had seen an S10 pickup on the ground so I was hoping the part would be the same, AND, I couldn't remember if the S10 still had a front end or not. But I didn't need to worry because it turned out to be my lucky day. The yard had just taken in a '98 Blazer, sitting right up front, on the ground, with room to work around it, and the front end hadn't been hit. The baffle and all the clips were factory perfect. I also scored another good handful of odds/ends and the whole shebang only cost me $20.   Got everything back together and it fired right off, sounds good, runs good. I've got a little coolant drip from a lower water pump bolt (D'OH!!). I did the right thing and snugged it down a little bit, and of course that didn't fix it. Yet again, I will have to soak everything in coolant to drain it down to the water pump, remove the bolt, and attempt to re-seal it. Nothing is easy on this truck. Nothing. But now all the radiator plastics are correct, snug, and fully functional. No more rubbing on the cooling fan. It runs, drives (took it for a 30 mile drive last night), no Check Engine lights, EGR is working, no vacuum leaks. We're getting closer...   The replacement wiper motor arrived yesterday. The tailgate was already disassembled and waiting, so I threw that in. It works! Sort of. Two new issues on the list. While the motor is strong enough and the gears aren't stripped, the wiper is hanging up on the bottom of the rear glass. This is the old style where the lower half folds down like a truck tailgate, and the glass swings up, and they meet in the middle when closed. The glass isn't sitting flush with the tailgate, now that I look at it. No rubber bumpers that I can see for adjusting, so I'll have to look at the hinge adjustment to see if I can correct it. Also, the washer/squirter just dumps fluid underneath the truck. The lines actually run inside on the floor so I'm guessing the tailgate is soaked at the rear trim and the line is disconnected. There's also a drain there....probably for this reason.   The leaky water pump bolt was really disappointing. JUST STOP LEAKING...OMG!!   Replacing the window motor and a rear door speaker are still to do, and then everything will work. I want this to feel like a "good" vehicle worthy of dropping $600 for new tires before I do. That means no leaking first. I hurt, and I'm kind of cranky, so I'll probably take a day of rest and do the water pump again tomorrow.

      EV's have their nuances too. Best to operate the current type of lithium batteries between 20-80% charge. No real need to charge until you hit around 20%. Occasionally charge to 100% when needed. Longer term storage, battery should be 50-60%. At least those are the guidelines for our iX. We've been exceptionally good to the battery in that car...easy to do when you can charge at home like we can.   EV's lack so many of the rituals and so much of the visceral feeling ICE vehicles provide, which is why I think they're hard to accept for a lot of gearheads. They're fun in different ways, though.

      Winter Returned

      We have got a lot of rain lately, we needed it. Storms/lightning took out a floor fan. Dirt roads badly rutted from run off.   Power here is sketchy, whole house surge protector in the service panel and all electronics plugged into surge protectors. My biggest concern is my stereo, I've been an audio nut for years. $25 k in equipment. Stereo is on it's own special surge protector.

      Happy Birthday!  I also turned 72 this year.  In some groups I consider myself to be a young senior and in others I realize I have serious years behind me!  In June I spent a week in the hospital due to a blood clot following knee replacement surgery.  The hospital Doctor assigned to my care specialized in Geriatric medicine!  He is a great Doctor but the fact I required this type of specialized care  made me feel old!  Aging comes with new challenges but I sure appreciate getting older!  It most definitely beats the alternative!!
