The important bit is that the vehicle has a 24 gallon tank, which means you had almost another 2 gallons left go. You had another 8% of the tank left to go which would have given you 8% more range, or roughly 49 more miles. So 660 miles would have been the full tank.

At the end of the day it’s a giant heavy box being pushed through the air at 80mph. I’m super impressed. Where the speed limits are lower if if you were going 65 to get the max range this thing would probably be knocking on 30mpg door.

aero starts becoming a big issue around 80 mph. Even worse for bricks like this. At a steady 70 it would probably gain 2mpg or so. NOW, take that thing down I10 where it is nice and flat and low altitude and I bet 30mpg is definitely possible at 70mpg.

You need to get exempt diesel truck (depending where you live) and have all that junk removed from your engine. As soon as my 6.6 duramax was no longer under warranty I removed all the junk off of it and now the engine runs better than when it was new and has not needed to go to the shop since I removed all of that other than just regular maintenance. EGR & DPF will slowly destroy your engine and you’ll be lucky to get 200k miles out of it. With the EGR and DPF it’s just a matter of time before something malfunctions on the system and the computer puts you in to limp mode and leave you on the side of the highway.

All hand calc I am getting about 25-26mpg daily driving all colder weather got my truck in Sept. Towing varies my trailer type and load. But 2k extra weight in truck and towing a 9klb loaded trailer it got about 11mpg. Towing snowmobiles and 1 in the bed got about 18-19mpg. Towing suv 7k lb on a flatbed got 14.5mpg. If you want amazing mpg stick to 55mph or 65mph. That's 9th and 10th gear in their sweet spot it seems. When I do that on short runs I see 30mpg+. Driving from Mankato, MN to Minneapolis doing about 65mph on avg truck was at 38mpg on a 60* day. I'm excited to see summer mpg. This 3.0l hates cold weather for mpg.

27 MPGs at 75 MPH in a big truck. That is dam really good!!! Ultimate truck......3.0 diesel with an electric motor behind it, mated to a 10speed.... there will be your 40+ MPGs with all the power and torque.

[@ALMX5DP]

An electric motor may help city economy, but probably wouldn’t do much if anything on the highway where it’ll have limited opportunities to regen.

[@jacobkrzyzek5777]

@@ALMX5DP Correct and wrong. Combining the two motors will gave you greater work, thus not needing as much energy from the diesel. Around the city you could shut down the diesel and be full electric. An electric motor has its peak energy at zero rpm. Any combustion engine needs to increase its rpm to achieve this using more fuel from a stop. Having an electric motor allows the engine to not need as much fuel to bring up the rpms and move weight, due to the electric motor covering this rpm gap. On the highway, the electric motor would greatly aid the torque numbers helping the diesel move the vehicle with less continuous effort, again needing less fuel to move the vehicle weight. ie: Rolling friction and Newtons law of motion.

[@ALMX5DP]

@@jacobkrzyzek5777 I did acknowledge the city benefits, but for the highway an electric motor still needs to get it's energy from somewhere. Diesels have great highway advantages due to their combustion design, so aiding torque figures while already on the move would be minimal. And once battery energy is depleted, it'll just be dead weight until it can recharge (which is few and far between in a highway scenario). That's why most hybrid economy figures favor city over highway.

[@jacobkrzyzek5777]

@@ALMX5DP this is true! a diesel for this reason could also be the battery's charging unit as well as regenerative braking would be helpful....for a long story going back and forth, having a hybrid vehicle does produce better fuel economy, I'm not talking about the end all be all, just something better for today, and a help into the future.

Great review. I'm not one to run the fuel level to low, either. To many moving parts are lubricated by the fuel.

I've averaged 28.6 mpg over 400 miles with my 3.0 AT4/crew cab/6.5ft box and loaded. Best truck I've ever owned. Quiet, comfortable and have only had one issue with a small leak in the radiator at 22k miles. GM replaced and that was that....Nothing engine related at all. Yeah my MPG calc is always off by about 1-1.5 mpg on the low side over a full tank. BUT...it WILL burn oil if you're pushing it 80+ in hot weather for a few days. Just how low tension rings will act. Nothing to worry about though. A friend of mine is a 27 year GM master tech and said a quart of oil over 5k miles if running loaded/hot/fast is NOT an issue but just a fact of life with these engines. Under normal driving I don't lose any over my normal 5-7k OCI though.

[@terrygarvin1980]

I have a 06 Dodge 4x4 Crew cab with 5.9 Cummings diesel and that massive truck gets mid 20s mpg and great milage when towing a large box trailer. I like having to worry more about when to empty my bladder than fill my tank.

Forty years ago, early June, I drove the brand new VW Passat B2 Estate diesel. Did 5,47 mpg then. Ten years ago, Volvo S80 had 21,13 gallons diesel tanks in them. You could easily drive 1000 miles with them with some motors and two wheel drive, and up to 1250 miles a lucky day. In the 1990s I drove a taxi. With a Citroén XM 2.1 diesel automatic, I constantly drove 800 miles on a tank of diesel, in city driving ... as a taxi.

[@martyi398]

Routine maintenance oil changes, fuel filters, fuel treatment etc. 6. Injector replacement, turbo charger maintenance 7. Higher cost for diesel hard parts, starters, alternators, water pumps, batteries etc. in the short term (3-5 years) you could possibly justify the diesel if you drive an unusually high amount of miles and or haul very heavy loads on a daily basis, long term (10 plus years) my opinion to justify the added cost you would have to be hauling heavy loads GVWR outside the capacity of gasoline drivetrain setups and or unusually high mileage as well like a Hot Shot logistics driver would do on a daily basis, Have a great day, Marty

Like others have commented, I'm kind of underwhelmed by this result. After 11 years in an Escalade, I just bought my first Ford Expedition Max with the 3.5L EcoBoost. We did 2200 mile trip from Utah to Oregon, California then back and averaged 21 mpg at 80mph (the legal freeway speed :-). The range on a tank of gas is just over 600 miles not to mention it has 470 lb-ft torque. With the premium price of diesel + DEF, I can't see why I'd buy this diesel Yukon over the EcoBoost.

[@andrewsmith9575]

Cool truck! Road trip! Nice review guys!

[@patriot9455]

You are traveling I-80. From Boulder to Denver is nice. from Denver on it is a gradual down grade. approximately 5000 feet to about 500 feet of altitude over 800 miles seems like no big deal. I drove a big truck, on that route, eastbound, I went from 6.2 mpg to 6.5 mpg, in the summer, with a 500HP Cummins and full trailer of freight. I got almost half a MPG better going east than going west. That was a regular route and my company paid a fuel bonus, so I figured out how to get the best economy out of the truck. it seems this truck is designed to run at 70 MPH. imagine what It would do at 65 mph. It would be interesting to do the same run the other direction and get a comparative, unless you, like me, enjoy being home to much. That is one of the joys of not driving trucks anymore.
