Chev?chevy looks ugly? I’m a GM guy and both trucks are beautiful and quality. But… I mean butt! When you look at the wheel well shapes of GMC to CHEVY… looks like GMC cut corners 😅 and how the front bumper meets the front quarter panel with the plastic fender flares is extremely choppy. They made the right fix on the HD trucks but overlooked the 1500’s. Chevy has maintained a well blended marriage. The GMC dash is equivalent to the Denali which is a huge plus! Chevy doesn’t offer anything different from LT to High Country… a bit boring! My brother in law ordered the exact specs as your truck taking delivery next week! You both have a gorgeous truck in that same gun metal gray. The carbonized gray grill and wheels pull everything together with your choice of cab boards. Congrats! Nice truck!
3.0 Duramax Diesel here @ 8.0 liters/100km with max tow package (including different rear end gears!) good for 12900 lbs towing capacity (conventional trailer)
My buddy has the GMC 6.2 AT4. Normal driving he’s getting 17-19 highway. I have a Chevy Duramax RST Z71, getting 26+ highway. I don’t think your 45mph fuel mileage applies to regular people-but I could be wrong.
I'm 320 and 6 ft and considering either the 400, 500, or 650. For a long term bike, also my first. Dont wanna have to keep buying or selling to upgrade.
How funny that happened to a co worker he was driving around the construction site not knowing his tail gate was down the whole time luckily his tools didn’t fall out 🤦🏻♂️
just commented on another vid but just saw this is ur recent video up for the 3.0L duramax, and i noticed u have the transmission fluid temperature on ur cluster and wanted to know how high does the temperature go for you if ur driving long distances or even in the city?
when driving long distances, does the transmission fluid temperature stay around the 196°F-200°F area? asking because i have a duramax 3.0L and wanted to see if ur getting those temps as well
My lm2 is around there. TBH , I hate hot temp, so I removed one sutter at trans cooler, so it get more air flow, and install a bypass thermostat PPE. Ow I’m running around 170-190 in florida. No more 200+
I have zero experience with both of these engines. What I do have experience in is calculating "actual" cost of driving different vehicles. You MUST calculate total cost of a vehicle which includes many things most don't think about. Compare vehicle msrp, resale values, Insurance costs, maintenance costs, DEF if diesel vs not, diesel vs gas prices and a few more things but you get the picture. Back in '07 when I bought my Dodge Ram diesel I calculated I could pay .50 per gallon more than gasoline in my Silverado and break even with fuel costs. That's just one example I calculated. It's not just about MPG. Bottom line is, what is your total cost per mile to drive xxx vs xx? It's all simple math.
@@brians.1357 I did not know that. We just sold a Subaru Forester XT that required premium fuel due to its turbo. We bought a new 4 Runner that gets about the same MPG as the Forester but we save a little because it doesn't require premium. Insurance is more of course and the msrp is 23K more than the '15 Forester. Ya it's more money for sure but that's inflation for you. I question how people are calculating their mpg. Are they doing it by hand or using the trucks computer? I've had vehicles in the past where the computer was off a little and some were off a lot. Are they resetting the computer for a trip? Are they observing actual current time mpg? I don't know what both trucks are capable of calculating or if they are accurate.
I averaged 35mpg with the LZ0 yesterday going through Yellowstone Park, only averaged 23 with the 5.3 liter, averaged about 22 in the 6.6 duramax. Oddly there are times when they are similar though (esp during regen) Currently own all 3.
I went to Florida in February with my 2023 AT4 3.0. Put on 3500+ miles. On average I got 32-36.5 mph. Mostly hwy but also driving 75-85 mph . Not complaining at all.
Yea it all depends on how fast I drive, if I go between 55-65 I can get crazy mpg like 33 my best was 40.3 on my 24 3.0 2WD 18” rims but if I drive over 70-80 it’s like 23-24 I had a 2018 5.3 v8 and got great gas mileage around 23 I also briefly had the 2.8 it was around 19 mpg but I was always gassing it definitely depends on how and where you drive
Great video, Do you use the Auto Start/Stop feature to achieve that fuel economy? I’m curious does Sport Mode permanently disable Auto Start/Stop? I know a lot of people dislike turning it off every time they enter the vehicle.
I turn off auto stop start every time I get in the truck. I know sports mode gets slightly less MPG just because the transmission shift later in the RPMs, but it’s not that big of a difference in my opinion.
Just bought the 2024 Denali 6.2L with super cruise. Paid $75K for it and I Love it. Just crossed 1000 miles in it yesterday. Dope truck bro. That color is so nice
little worse mileage ... but WAAAAY better sound and powerband. the 3.0 is a great engine and reliable, nothing wrong with it. but the 6.2 is for me all day
Something is wrong as your results, high 6.7L and low 3.0L results, don't appear repeatable by others. It would be all over RU-vid if was commonplace narrow spread difference yet there are none, nor individuals reporting similar in comments - none thus far on 6.7L and 3.0L typically exceeding yours. For a larger sample, just checked Fuelly which reflects actual usage and calculated on mileage and gallons at fill-up. There is a HUGE spread, in fact the average 16mpg for the 6.7L was the low end 15-16mpg for the 3.0L which I presume would be towing and RV. The 6.7L average 16mpg on 52 fill-ups with a high of 21mpg on 3 fill-ups and low of 12mpg on 2 fill-ups. Of the 12 vehicles in the sample, the high average with 4 trucks was 16mpg. Further the 5.3L bested the 6.7L by 1 to 2mpg but wont go into specifics. Now the 2024 (I know yours was a 22 which had similar results) the high average ranged between 22 and 24mpg on 358 fill-ups - which far exceeds the 6.7L's 16mpg. On outliers, 31mpg on 2 fill-ups and 15mpg on 8 fill-ups which I presume was towing mileage. Of the 63 trucks in the sample, 12 trucks returned the high average at 24mpg.
I personally feel like this depends on how you drive. I know people that have 3.0 that claim they get 30mpg on the regular and there are people that claim they get in the low 20s on the regular. A lot of this trip was highway (country) miles which is why the 6.2 got 23 miles of the gallon. In the video, I was not saying that if you get the 6.2 you’re going to get 23 miles to the gallon every single time you drive but I believe you can consistently get in the 20s. which is still 4-7 MPG’s difference or as others claim up to 13mpg from the Duramax. But I was just going off my results.
From my experience, they relatively get the same MPG. But the 5.3 does take regular and the 6.2 recommends premium so the 5.3 would be cheaper in the long run.
