I choose the 3.0 because I drive 60+miles a day to work, needed a new truck that was fuel efficient  and didn’t need a 3/4 ton.

4 bangers NEVER out do a v8.  4 bangers need boost to even get close to a v8 and people love their rice rockets screaming IIIIIIMMMMM GAAAAAAAY with their fart cans.

6.2L Because go big or go home! Of course when I ordered it gas wasn't stupid expensive! I got to order my truck and decided it wasn't too much more to go with the 6.2 over the 5.3 and in the Custom trim the trans was the bigger difference, from the 6 speed with the 5.3 to the 10 speed with the 6.2. The diesel wasn't an option on the Custom TB in 21.

enjoy the big v8, those will go away soon, I ordered mine with the 6.2, I can't wait to get it.

If there’s an E-85 option with the 5.3 that would be my choice. Close to the 6.2 horsepower on E-85, regular fuel option for trips. My Texas Edition GMC was a jewel.

They did away with the E85 when they went from the LS based motor to the LT based motor. My Avalanche is E85 5.3.

from my short research all chevy have e85 tune on their ECU , all you have to do is install a e85 sensor and turn ON the tune with a HP tuner, correct me if I am wrong.

I went with the 5.3L. When I got mine, gas was stupid expensive. In my area, premium is 70 cents higher than regular. Since I commute to work, I didn't want the added costs.

6.2.  Dont need the mpg of the 3.0 duramax and dont care for the maintenance costs of a diesel.   The 5.3 is essentially obsolete and an ancient engine, the 6.2 is a beast and its modern tech really shines through.  Im surprised the 5.3 is still produced to this day, honestly, and the 6.2 isnt offered as a standard option with the 3.0 duramax as an optional sidegrade.

6.2L, love the motor and that extra power!
Now that being said, the 5.3L is a great motor!  Paired with the new 10 speed it truly does everything I need a truck to do. My stepdads just runs very well. All around it averages 23-24 mpgs.  It also gets just as good MPGs pulling my boat. 
 

He doesn’t have to use premium which is awesome, because right now here in Midwest it’s 80 cents higher.  
 

@Anon12345 How can you say the 5.3L is ancient? It’s essentially the same as a 6.2L in regards to the technology in both engines? 


I don’t think the V8s are going away just yet! I have heard rumors that a new 5.7L (350) was coming back??  Wouldn’t that get the old blood flowing for use boys!!  Either way GM does need to bump up the power around 40 HP to stay very competitive with everyone else.

The 5.3 is just a slightly improved version of the same 5.3 we have had for years now.  Its the same block and internals with the cast iron bottom end.  Its a pretty ancient engine compared to what the 6.2 offers, especially comparing how the 6.2 has a forged bottom end.  

 

If the 5.7 comes back that would be interesting!! I would hope forged bottom end with good numbers.

5.3. Running 87 octane I'm averaging just a tick under 24 MPG on my 58 mile round trip commute and have more than enough power to tow my boat. When the roads are wet and the bed is empty I have to be careful of the back end wanting to come around if I push too hard on the skinny pedal. I don't need any more power than the 5.3 gives me.

 

Even the crappy gas served up in neighboring Florida doesn't give me any problems. It always seems to be a couple of points under the posted number on the pumps.

I actually can't believe GM killed the chevy 350 one of the best engine ever made.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Gas fill door

      By newdude · Posted

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
