Great truck! My son got his 1 year ago and gets 35 plus on highway and 23 plus in town!! The issue is this screw job that GMC dealers are doing to customers! I have leased 4 previous trucks from a local dealer in Houston and have purchased 6 GMC trucks and 2 cars in my lifetime! Went to same dealer, was told 7000 over sticker , no discounts , I work for big company and we usually get 2500 off and repeat GMC buyer discount of 1850, take it or leave it. I called GMC and was told the dealer would honor GMC discount or else but nothing could be done with supplier discount! Finally found a GMC dealer in Conroe , Tx that would work with me and gave me both discounts and no market adjustment markup of 7000 dollars. Ford is doing it and so is many dealers and when it settles most long term buyers will no longer be loyal to them!

I almost optioned the 3.0 diesel but with many short trips, I didn't want the HUGE expense of replacing the DPF at approximately 75,000 miles. (Several buddies had this expense with short distance driven diesels.) That expense, with added diesel and DEF fluid cost, made it a wash. The rubber oil pump belt maintenance cost that requires dropping the transmission further increased the maintenance cost. (Can you imagine paying $1,000 to replace a $15.00 rubber belt? Start saving now.) I just don't see the financial benefit of the diesel, at this time. My 2022 5.3 Tahoe Premier with DFM averages 26 mpg on the highway. I am truly impressed with this mileage, without the COSTLY maintenance the diesel WILL have. On a side note, GM just announced that the 2023 3.0 diesel has a few upgrades that hopefully fixes these costly maintenance problems.
There are added expenses with a diesel yes. The big factor for us not only the mileage but towing. Bought the wife a 22 Suburban with the 5.3 and it was a dog. It replaced our 19 Yukon with the 5.3 and did worse than the Yukon. It would constantly downshift and search for gears no matter how you drove it and it was getting 6MPG hooked to the trailer. Got rid of that and got the Tahoe. Best thing we could have done. Pulls trailer like nothing Is back there. Averages 13-14. It’s a great power plant but it’s just not for everyone.
My 2021 Tahoe 5.3 RST gets 18 mpg going downhill with a tailwind. I don’t know how it’s even remotely close to possible for you to get 26 mpg out of one of them.
@@specialestness I do 80% highway driving at 55-58 mph with cruise control on. I live on the eastern shore of Maryland and it is FLAT. I anticipate and coast to red lights and they often turn green before I actually stop. It takes a LOT of fuel to get your truck up to 30 mph. Coasting is your friend! Remember, every-time you touch your brake you are wasting the fuel that it took to get you to that speed. My best tank was 29 mpg, which I still have saved on my mpg screen! It takes patience and practice. If you have even the slightest heavy foot, you will never get there. I run 38 psi in my tires (cold) and coast up hills. It's a game for me! Good luck!
@@testtesting2868 I live in North Central Montana and we’re not flat and have much faster speed limits. We also get copious amounts of wind coming off the Rockies. The lifetime average at 45,000 miles is currently 15.7 mpg and the best 50 mile mpg is 27.3 from a recent road trip in Iowa where highway speed limits are 55mph. I find it shocking how much worse the fuel economy is compared to the previous bodystyle. Even just watching the instant mpg while putting around town it’s much worse than our previous 2017.
@@specialestness Understood. There is a lot of wind resistance when driving these large boxes at faster speeds! When I drive our 2022 5.3 Tahoe to Florida, I-95 from Maryland at 70 -75 mph, I see 21-23 mpg. I-95 is fairly flat ground and I run with the cruise on. When I head West into the Appalachian Mountains into West Virginia at 70 mph, I see 19-21 mpg. Around town, I see 15-17 mpg. I tell my wife the Tahoe truly is a highway cruising vehicle and not a town vehicle, when it comes to efficiency. I previously had a 2015 Expedition Max with a HUGE fuel tank. I do miss that fuel tank! The Expedition had a 3.5 twin turbo V6. It was quicker than the Tahoe and about the same efficiency on the highway. Around town, the Expedition was more efficient by 2 mpg or so. We sold the Expedition as the aluminum hood and rear hatch had "white rust" that couldn't be stopped. Beautiful vehicle but the constant cancer rust was driving me nuts. The only way to properly stop the rust was to replace the hood and hatch at a cost of $7,000.00. At that point, I traded the vehicle in on the Tahoe! We try to stick with our 4 cylinder, 5-speed manual transmission little wagon, when scooting around town. In this, we see 30 mpg! As many as 38 mpg, at 55 mph with the cruise on, on the flat Eastern Shore of Maryland.
I'm a diesel guy but by the time you factor in the cost of Def fluid, ¢60-$100 more for diesel and more expensive fuel filters and oil and oil filters, it's basically a wash as getting a gas motor
For most folks maybe. I do my own oil changes and Maintenance so saves money in long run. And the torque for towing you aren’t getting out of a 5.3 6.2 yes but then you’ll be spending more than just getting a diesel.
@@uptownautogarage6833 doing the maintenance yourself saves a little bit but all the other costs are still there, I hope it's going to be a great motor but it's too early to tell yet, don't think there's any with 300-400k miles yet
@@murdered1415 I'm on the fence with a diesel. I've owned several diesel. I'm leanings towards a gas engine cheaper maintenance and now days you can get 300k miles out of a gas engine.
fuel filter is only $30 every 30k miles. DEF is cheap at truck stop pumps (about $4 per gallon), 5 gallon DEF tank for $20 to fill will last 5k miles if not towing. Price of diesel fuel will not be high forever, at some point it cost about the same as midgrade gas.
@@BrianNC81 I feel the same. I just bought my first 3.0L Duramax (Sierra SLT). Only have 20 miles on it. But I figured the cost of fuel will drop (only $1 higher per gallon than gas in TX) and the DEF is no big deal. Of course, I do not tow and only commute with the truck..... Those fuel prices have got to drop though, this is frickin' nuts!
My tows awesome. Had a 2015 5.3 wich was ok at best for emergencies lol. My '22 tows a 20ft feather light trailer loaded with a full size pick up with ease. Pulls my 20ft. Cargo trailer also with ease. Only problem I encountered some sagging issue that companies havent made an air bag set up. Full tank last a solid 2 weeks at $120/tank
WISH THEY MADE A TITAN TANK FOR THESE OR THE 1500 SILVERADOS. NEED JUST A COUPLE MORE GALLONS WHEN PULLING THE CAMPER TO MAKE A ROUND TRIP WITHOUT STOPPING. MAYBE ONE DAY THEY WILL.
