Duramax 3.o vs gas 5.3L

Duramax 3.o vs gas 5.3L

Postby nwaring [OP] » Jul 26 2020, 11:06pm

I have a 2012 2WD Silverado 1500LT crew cab short box and I tow a 5,500 center console boat between Ohio and Florida. Anybody got an opinion on how much better the 3.0 Duramax will handle this load. The 5.3L does ok, lots of RPM and less than 9MPG. I read where the 6.2L has the same upcharge as the 3.0

Thanks

From the reports I have seen and read, the 3.0 does pretty good for itself. It won't have near the get up as the 6.2 does off the line, but from all accounts it drive similar to the 5.3, but with more grunt down low, which is generally where the diesel shines, and also why you will almost always get better mpg while towing with a diesel.

With it being so new still, longevity would be the main point of contention for me. But besides that, it seems to be a pretty decent motor so far besides for a couple introductory issues like everything will have.

I still am wanting to drive one to see how they are first hand. Then I'm really eager to see what tuning comes out for them.

the 6.2L Diesel is a $10,000 upgrade charge,...
the 3.0L Diesel is a $2700 upgrade charge.
….
if you think back 10 to 15 years ago, the Powerstroke & Duramax 6L engines made about 500ft/lbs of torque, now that's what the 3L diesels are close to making!

SSMike: there is no current 6.2l diesel. The 6.6 Duramax is almost 10k upcharge but only in the HD trucks.

I was at the dealership about a month ago and while mine was getting an oil change I took a 3.0 Duramax for a little shake . To say I was impressed was an understatement. I was merging onto the highway under normal to me acceleration, looked down and I was flirting with 90. I'm pretty sure it would outrun my truck all day long. I can only imagine it tows very well also, and I'd venture to say you'd do much better than 9 mpg.

You only need to drive one to love it. It’s night and day power over the 5.3. Steady pull at low rpms. The 5.3 (and the 6.2) have to really wind up to pull. The diesel option is about the same cost as the 6.2. I would think if you do any amount of miles the fuel economy would be a plus. Mine is doing amazingly well on fuel even though I haven’t gone on any long trips yet. Time will tell how the reliability will be, so far I’m hearing of some CEL codes being set but the gassers doesn’t that too.

Happy Holidays to you too! Yes you will really enjoy the Duramax compared to the 5.3. So much more power. Low rpm pull. Enjoy it!

Duramax,... I LOVE the Torque and the feeling of acceleration right away off idle. GOOBERS full of torque.
I was constantly spinning the rear tires in 2 wheel drive. I have put the truck into the AUTO all wheel drive mode, and it accelerates like crazy all the time, going around turns and when raining.
My foot is on it constantly, it is so addicting and fun to drive.
