:surprise:

So I was just checking out you tube for real world tests from folks who have already received their 2018 f150 diesels and came across this thread....

youtube.com/watch?v=RRHmz1j5aTg[/url]

F150 diesel pulling enclosed trailer with 7000lbs in it 97 miles...used 8.4 gallons of diesel...thats only 11.6 miles to the gallon...my current vehicle which is a 2013 f150 3.5 liter ecoboost would get about 8 miles to the gallon pulling the same load and trailer...not a huge improvement in my mind....kind of a disappointment from what I was expecting...they mentioned they did the same test with a dodge and it came in at 13.3...even worse news since I was expecting ford to be way ahead of Dodge with everything I have been reading online.....

only huge benefit I see is they were running at about 1600 rpm at 70 mph...would be closer to 2800 rpms plus with my current f150 which creates quite a bit more engine noise in the cabin than I would like when pulling a four place snowmobile trailer at higher speeds....

I know a lot of people were hoping for class leading efficiency here, and these 'real world' numbers are probably going to make it tough sell over the Ecoboost. Though I think that the EPA rating for these engines highway economy is actually done at 55-60mph not 70.

I just took a initial Camping trip with my 3.0 Diesel and averaged 13.9 MPG. My trailer weighs 4777 Dry and I had a full tank of water (about 450 LBS) and camping personal gear 300 Pounds so close to 5527lbs.


My rig is a 2018 F150 3.0 Diesel Crew Cab SB with 3.55 rear gears and 4x4.

How did it do towing? Struggle any? I will be doing some long range towing with about 4000 lbs next week. Curious to see how it does in the mountains.

Hello,
The truck performed very well as a matter of fact We forgot the trailer was behind us.

We traveled from the Tampa area on Interstate 75 Northbound for 125 miles and camped two days then we drove home.
We have a high quality weight distributing hitch and the trailer did not sway at all when passed by big rigs.

The F150 3.0 was a pleasure to drive.

How did it perform compared to the 2015 F150 2.7 EcoBoost you had? Assume you also towed the same trailer with that EcoBoost? How did the EcoBoost do for mpg towing that trailer?

Just asking for curiosity sake.

I don’t put any faith in fuel economy tests. Especially the YouTube ones. There are too many factors that can affect the results. I came out of a 2012 ecoboost, which averaged 14 over 160000 miles. I never reset the trip2 counter so that I could monitor the lifetime mileage. I plan on doing the same with my 2018 diesel. While the computed mileages aren’t 100 percent accurate, most of my spot checks which were hand calculated were within .5 mpgs. I’ve driven the 3.0 almost 4000 miles so far and the average is 25. Time will tell, but so far it’s been pretty impressive. I regularly take a 450 mile trip about every month or 2. The best the ecoboost ever got on that trip was 18.5. I’ve made that trip twice with the new truck and the first time I got 28.5 going and 30 returning ( I had a tailwind on the return trip). The second was a little lower at 27.7 one way and 27 back. I really loved the ecoboost, but there wasn’t anything eco about it. I have a 25 ft pontoon boat that I was getting around 10 with the ecoboost. (It’s like pulling a parachute). Haven’t pulled it with the new truck yet, but will post after I pull it a few times to get a feel for it.
I’ve seen several posts about wanting a 36 gallon fuel tank option, and I was concerned about that too when I bought it. However. I am regularly getting 550 miles plus on a tank. That’s about what I would get with the ecoboost truck with the 36 gallon tank. I’m thinking when towing the 36 gallons would come in handy though.

No doubt the 3.0 will do the job on flat land, it's in the mountains that has me concerned.

I have almost 37,000 miles on my Ram Ecodiesel with 3:92 gears and I can tell you the weak link with the Ram= towing up hill ! Mine is tuned and deleted, btw. Power is not the issue, watching the oil temp gauge rise, towing a heavy trailer up steep hills is somewhat disconcerting. I know some guys have swapped grills to get better airflow and deleted the active shutters. So heads up, if you are looking at both. On the other hand, 3:92's may be an advantage, don't know.

This is the area I'm really interested in. Ford appears to have beefed up the cooling system on the 3.0 with the mechanical fan. I'm really curious as to how it performs under hard towing. I routinely overheat my Ecoboost towing the long mountain grades when it's hot out, and so do a bunch of others. We've narrowed it down to the electric fans being the culprit as people are getting minimal gains from radiator upgrades. The fans on the Boost are the same size as the one's on my wife's minivan. :rolleyes:

SuperDave, I know guys with the Ecodiesel Rams that tow for a living run a bigger oil cooler and transmission cooler. Also a finned aluminum transmission pan that holds 2 more quarts for the ZF transmission, some remove the active grille shutters and there are a couple Ram grilles that flow much better than my "Big Horn" grille. Mishimoto makes thicker radiators and there are aftermarket intercoolers with bigger capacity to reduce EGT's, though I don't hear much about EGT's being a problem. 1 guy (Verndiesel) has well over 500,000 towing miles on his Ecodiesel, guess he's figured it out, haha. I do know some guys are putting electric fans in front of the Ecodiesel's radiators. Good to know Ford has a mechanical fan on the Powerstroke 3L. Imagine that, simple and has worked forever! My 2005 Ram hemi had one, towed way over the limit, temp gauge never moved, also ran a 180F thermostat.
