They are in another thread already here, but:

The first engines to be produced will be the 5.3L V-8 equipped with an eight-speed automatic, and the 6.2L V-8 equipped with a 10-speed automatic. Both offer more than 5 percent improvement in city fuel economy, for an improvement of 1 mile per gallon based on EPA estimates.

 

Models equipped with the 5.3L V-8 and rear-wheel drive offer an EPA-estimated 17 miles per gallon city, 23 highway and 19 combined. Models equipped with four-wheel drive and the 6.2L V-8 offer an EPA-estimated 16 miles per gallon city, 20 highway and 17 combined.

So the auto stop and multiple cylinder deactivition  and only 1 mpg gain. 

Apparently, and that is even with the 400 or so plus pounds of reduced weight as well.

Disappointing for all that expensive technology if you ask me.

Something must have changed in the EPA's fuel economy testing parameters. The 2018 F-150 lost 1 MPG on some models compared 2017's, even when very little changed. The 2019 Ram 1500's fuel economy is the same as the 2018 Ram 1500 despite losing 225 lbs and gaining a bunch of aerodynamic improvements like the super low-slung active air dam. From what I recall, the EPA frequently updates the parameters used to calculate fuel economy.

It doesn't sound like a lot but I believe a 1 mpg improvement, especially when added to other recent improvements, is significant.  The improvement in efficiency, power and longevity of pickup trucks has been astounding.

The longevity part, you may have to wait awhile. The current redesign of the 5.3, 4.3 just happened in 2014. There’re coming out with another one this year. The 5.3 prior to cylinder deactivation would routinely go 300K miles. I doubt to many after 2014 have gone past 200K yet.

Does anyone know the fuel economy numbers for the 2019's? Specifically the 5.3L and 6.2L. Thanks!

I have a 2019 LT TrailBoss, I am averaging 16.5 around town and 20 on they highway. I only put about 200 miles on so far though.

The government testing is done in an enclosed space with no wind and air drag to overcome. The faster you drive the less likely you are to begin to approach the EPA numbers. Any way you look at it, with a pickup truck the engine is having to push a brick through the air and that takes horsepower and fuel.

 

For my part I use a 16 MPG diesel truck, a 22 MPG gas SUV, and a 45 MPG gas hybrid Prius sedan. We put about a third of our miles driven each year on each of these vehicles. Now if I used the 2500HD as my daily driver I would be buying a lot more fuel and spending at least twice as much on maintenance and repairs.

Also for 2019; they got rid of the 3.08 gears which likely lowered their MPG rating. 

 

I think a few things are at play here; no more MPG gearing (lowers mpg), likely EPA testing changes (lowers mpg), yet they improved mpg with weight loss, aerodynamics, new cylinder deactivation, and possibly start/stop.

 

I am not an engineer; but I have heard a vehicle at idle uses little fuel.  So, the S/S tech may be more of an emissions thing than aimed at improving mpg.

Its an awesome looking truck though sir!

Maybe it’s the way I drive, but my 2014 averaged 14.9 lifetime.

Amen to that.

When i run E85 and put my foot into it, my average is about 11.5! :loser:

      Took me FIFTEEN MINUTES to find this. Isn't that a problem? On the mainstream media I can INSTANTLY find 100 articles bashing President Trump ... but when it comes to TRUTH in American corporate news & search engines, it's carefully filtered to support ONE SIDE. A Republic cannot survive like this! Incredible! Even all the AI searchers out there failed as well! ChatGPT said it needed more details on the video that I provided a DIRECT LINK to! I thought AI was the be-all, end-all?? I had to dig it up myself. This should be FRONT PAGE NEWS!!! 🤬   Here's the statement directly from our President:     Glenn Beck's reporting on the operation:   https://glennbeck.com/watch/videos/trump-just-revealed-a-massive-military-secret-that-lowered-gas-prices   In case that link doesn't work, here's the YouTube link:

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      Another 6.2L engine failure!

      By Chevy Man for Life · Posted

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
