Towing 5.0 3:31 VS 2.7 3.73

I just saw a post on this site by an individual with a 2.7. He towed a Jeep Grand Cherokee on a car hauler over 700 miles and averaged 15.8 mpg... That's pretty much what the 5.0 gets without any load at all.

That is good but a lot depends on the terrain. If it is flat and you keep it under 60 it goes a long way.

Unless he was only doing 45...downhill...and even then...

I questioned it myself but he posted pictures of the trip computer with all the numbers. Maybe the computer wasn't reset. But to still average that over 700 miles, reset or not, means that motor still did pretty good. I imagine that must've been very flat terrain.

I don't know how it's possible but apparently he has one of the most efficient 2.7's ever built.
There's a lot of uphill along that route...and a lot of downhill as well. I did notice that it took almost 13 hours which makes me think he wasn't going 70 the whole way...assuming he didn't stop, except for gas...that would mean he was averaging around 57 mph.
Still impressive nonetheless...I just have a lot of questions. At the very least, that is certainly not the norm. Most publications actually said the 2.7 was too thirsty even in normal driving...very few of them averaged more than 19. Attaching 8500 lbs...close to the max capacity of the 2.7....only dropping the MPG to 15 seems unrealistic.

I am the guy that posted it and I did both the computer and hand calculated it!
The mileage was as legitimate as you could get - I promiss. However 1/2 of the trip on the way to Southern CA was just the empty equipment hauler trailer. It weighs just a tad under 4K.
And yes, there were plenty of mountain passes as it was I-15 South and Northbound from Southern Utah to Southern CA and back. The Northbound trip was the loaded one with more climbing!
The secret to good mileage be it gas or diesel is speed and smooth consistency. I never went over 75mph- in fact in CA I never went over 60mph because of the law pulling a trailer is 55mph.
I've done the trip many times with a 2004 Cummins Diesel, a 2006 Cummins Diesel, a 2007 Toyota Tundra and now the 2015 2.7 Ecoboost XL 4x4 Supercab with 3.73 gears - all with the same trailer and similar loads. I bring back used cars ever so often.
Point is that both diesels pulled the load effortlessly, but never achieved any better than mid 15's mpg. They would stay in overdrive the entire trip.
The Tundra had plenty of power, but would downshift to 3rd and rev to around 4500rpm - would not hold 4th on the steep grades. It reached an all time low of 9mpg!
This little 2.7 that most feel isn't up to towing, either because they think it's too small, not a V8, or isn't built for hard work because they are desktop warriors - pulled this load effortlessly, mostly in 6th, and 5th gear, steepest grades it went to 4th but never revved over 3100-3200rpm!
It almost pulls as easily as the diesels and yes, it really averaged 15.3mpg for the round trip! I've got this down to a science and no reason to make **** up!
Most on here are either speculating from their desktop, stuck in a V8 world, drive too fast and always punching it, or have oversize tires and wheels!
I'm not!

Here's a couple of links to more proof of how these power trains stack up. First one is the Eco 2.7 with 3.55 towing around 8k with passengers, and second one is the 5.0 with 3.55's towing a similar load. I think it was just a bit heavier?
2.7 stays in mostly 4th gear and 5.0 needs to go in mostly 2nd gear!
2.7
5.0
2.7 vs 3.5 Eco
Remember, this is at altitude where the Eco's really shine over the normally aspirated V8's

Thanks drftr! I keep trying to tell folks that this motor is no joke, especially with the 3.73. Your experience really isn't all that unbelievable to me. I got about 11 mpg last weekend pulling a 22' boat in stop and go traffic for 30 miles. Someone else chimed in saying he got around 12. I too noticed that my motor (at cruising speeds) never had to downshift beyond 4th when going up hills. In fact, I was amazed at how well it stayed locked in overdrive on moderate grades.
