I wouldn't want to be the guinea pig on the 10 speed. I had issues with my 6R60 and 6R80 transmissions in the Sport Trac and the 2010 F150. They finally got the 6R80 where it's near perfect now.

:) Hi, well Ford and GM, together, designed and built those ten speeds so they should be good.

That's even worse. :)

The take away here is the Ecoboost is a solid engine, purchase with confidence. Otherwise there would be 7 pages of issues and not 7 pages of Ecodiesel mpg debate.

I have no dog in this hunt, but I clicked on this thread to learn a bit about the reliability of EcoBoosts (I've always wondered) and it appears to have turned in to a mpg and manufacturer debate unfortunately.

Would enjoy seeing this thread get back on track with some more posts from the OWNERS of the EBs on reliability.

We
Have a 2013 with 60,000 miles on it and love it. As you can see by the picture it sits just fine with no modifications. Granted it is just the wife and I so there is what a few clothes and some food and we typically don't fill fresh water using full hookups thus keeping the weight down. I am very pleased with the power especially when pulling out to pass. We are in the Ozarks in Missouri frequently and again no issue. MPG is typical really depends on the wind more than anything. It is a max tow haul with the 3:73 rear-end, On a side note it will due 100 mph in the 1/4 mile. that is about top end but is real quick and I LIKE IT lol

Every 6 months or so, I look on AutoTrader to find some of the high mileage Ecoboosts. There are always a dozen or so with over 150k miles. Twice I've seen them with over 200k. One guy on one of the forums is over 300k.

I own 2, one a 2010 Taurus SHO with 99,300+ miles on it. No issues other than a knock sensor which Ford replaced under warranty. #2 is a 2011 F150 , bought with 43k and now has 67,500+ miles on it. It did have the condensation issue which Ford fixed under warranty and has not repeated. I've got over 2k (plus God knows what the PO did) of it pulling an Open Range LT 272RLS and it pulls it awesome. Fuel economy when towing is right in line with V8's 8-11.

No issues with durability and there are plenty on the various F150 forums with over 100k on theirs. I'm not afraid.

Here's a 2.7 Eco Boost making almost 24 mpg.

I've seen up to 25 mpg on my 2012 5.0L also. It's just how and when you want to look at the mileage. Also were these 3.15, 3.31, 3.55, or 3.73 ratios. The '15s and '16s tend to have the tallest grocery getting gears of 3.31 in the 4WD Crew Cabs with either 5.0L or 3.5L ecoboost. I've had the 3.73 gears in my 5.0s and have been really happy with mileage. Also going to a heavier LT tire with more rolling resistance will also subtract 1 to 1.5 mpg .

AT the F150 forums, the Ecoboost 3.5L has been consistantly 1 mpg lower than a similar 5.0L and even worse while towing. The excuse is that anyone driving normal gets into the turbos with such a small displacement engine. To get the mpg up, you have to feather the throttle and stay out of the turbos. For me, that makes no difference. 1 mpg is nothing, power, driveability, reliability, and towing capability matter the most.

That being said, I've read about so many problems with the Ecodiesel, I was very surprised. I'd never consider a 1500 Ram because of their very low payload and the Ecodiesel's ~800 lbs payload makes it less capable at carrying a load than my wifes old Ford Escape. I thought about the 2500 Ram Hemi 5.7l and 6.4Ls before buying my '16 F150, but mpg were to low on both of them for my work commute.

I don't know the gears in the 3.5 EB but I recall the guy driving ~400 miles when advertising his fuel economy claim which I feel was good enough.

If I were buying a new half ton I would probably wait to take a hard look at Fords new gen 3.5 EB and 10 speed auto coming out for '17 model, but yes the 5.0 is a very respectable engine as well and deserves a hard look. But coming from a diesel having a turbo boosted gas engine appeals to me.

I just bought an F150 5.0L the other day. I drove the Ecoboost and it felt great, but so did the 5.0L. 5.0L is more responsive off the line and in the lower gears where the ecoboost has more low end torque in the upper gears.

I chose the 5.0L. While I feel the Ecoboost is much better and more reliable than it was in the 2011 - 2014 F150s, I still had reservations about all the issues I've read or heard complaints about.

That being said, this is the 6th Ford I've bought from my dealer and salesman. I spoke to the service manager who I've known for 7 years, starting when he was a salesman. He was glad I bought the 5.0L saying he's still seeing issues with the intercooler condensation. Saying he's even seeing it on '15s. Don't know if it was a defect of the intercooler or not as I haven't seen any complaints of this issue on the F150 forums at all with the new generation '15s and '16s.

I'm just happy with my decision to stick with the 5.0L that I loved in my previous 2012 F150.

I've had 3. 2 F150 and an Explorer sport. I never owned them long enough to rack up some serious mileage.

Early F150 had an intercooler issue that allowed water to puddle in the intercooler then get sucked into the intake under hard acceleration. This causes misfire, loss of power, and cel. The cel would go away and would drive normal. Happened to us twice on 2 lane trying to pass semi.

Some had issues with the timing chain and tensioners. Not sure what the root cause was/is there as I have not continued to follow the EB since getting rid of mine.

Some have reported excessive carbon and gunk build up on the intake valves. Carbon build up is the nature of the beast with direct injected gas motors. Combined with PCV and egr gasses plumbed into the intake with no fuel to wash off the residue. The residue builds up over time.

On cold mornings the EB runs very rich. This can cause oil dilution. Early EB came spec'd for 5w-20. Ford quickly changed to 5w-30 and put engine block heaters on all EB that came in with complaints of fuel smell in the oil. They recommended using the heater anytime it got below freezing to minimize how long it was running rich at cold start up.

My dealership was very particular about mods. I had an Airaid drop in filter and a bugs creek over the radiator and intercooler. I took it in for the intercooler stumble they wouldn't work on it until I removed the bug screen and put in a Motorcraft air filter. They then told me they couldn't recreate the issue so it wasn't an issue. The second time it happened the TSB was out so I took it back in. They told me the same. I told them about the TSB and they told me there wasn't one. I had to go home, print it out and take it back to them. Of course in then had to wait another 2 weeks to get my truck back in to have the TSB done.
