I've read this several times on various threads. I now have a scangauge installed and guess what. It's reading are within .1 - .2 mpg of the DIC. I guess the conspiracy goes all the way to the aftermarket.

Hi from AZ. . . my '11 Ecoboost F150 had that shudder/limpmode thing twice early on, both in driving rainstorms. I had to take copy of the TSB with me & sort of demand they fix it. They did with that piece in front of the intercooler, & hasn't happened again. 80k on it now & it's still going strong. I'll proably buy another, although the sticker has gone to $63k from my $45k when new. . . oh well, regards, Craig

I have a 2013 150 Eco Boost. Love the truck. Great pulling capability. Without the trailer, I ran for about 2500 miles without resetting the mpg setting. Was a lot of road and town miles. It showed 19.8 Lots of people ask me what mileage I get, and my first response wants to be-I don't care and would not have bought this truck if my concern was gas mileage. That thought usually does not translate into spoken word, but over nearly 3 years, 28,000 miles, i figure I get about 13.5 in town and around 21 on the road. The only problem is that when a fellow backed into my rear side panel, the Ford did not fix itself. Need to learn from Christine. Have not pulled enough to get a good reading.

Hey Greg,

There is an "old" documented issue regarding rain or water being sucked into the intakes. Ford changed or added something. I remember because I hang on the F150 forum and eco owners were having something done. The 2015 ones have a baffle. Dealers have to know about this as it is a TSB.

Oh, another thing on F150 comparison(s) to remember, the 2015 and newer model is a different animal from the 2013 and 2014 payload-wise. Ford removed a lot of weight and payloads are, in may cases, way up. So, a half-ton Ford F150, properly equipped, can tow any current model Airstream. 16-30 feet. with anywhere from 700-1000# of cargo/people to spare after #1000 tongue weight is subtracted.

You say you want to know about ecoboosts. I am a research nerd and went crazy digging up info on the ecoboost before buying one. Here is one BIG ah ha for towing that is easily overlooked when shopping- TORQUE AT HWY SPEED. I charted highway RPM using an online RPM calculator for the RAM, Chevy, GMC, Ford, etc and found that Ford has around 74% of its torque available at 70mph compared to Chevy/GMC with about 40% and RAM a bit more. This means, looking at their torque curves that they have to shift down to get to their torque sweet spot. GM uses higher RPM engines due to their design which means they have to race up to get to the power or, shift down more often to pull. This makes sense if you consider that GMs are turning around 1700 RPM at 70mph with 40% of torque available. Their torque peak is at 3900-4000 RPM compared to Ford's 2500 RPM. This makes for a totally different towing experience. It brings the diesel-like towing ease to the gas segment- not all that shifting back and forth and roaring engine, etc.

That said, there is another set of issues related to engine design though there is little choice.

GM has acknowledged a problem with their cylinder defeat technology as has Honda who also uses the technology. That once broken in and around 30K miles or so, (GM actually calls this high mileage) the engines start using more oil. In some write-ups, this is noted as excessive oil. Apparently oil starts blowing passed the inactive cylinders or some such- the technical description is on a link I posted a few months back. Again, this is not Ford propaganda but actually statements have been released by GM.

Meanwhile, Ford is not without issue. The ecoboost has an inherent problem of direct injected engines that, oil builds up around the back of certain valve stems causing rough idle and when pieces of build up fall off, it can be sucked into the turbo blade and cause damage. The work around is to have a drip can or some such, use synthetic oil, and use the "Italian blow out" drive every so often (get on it hard to blow out stuff).

Don't you just love modern engines? At least the Ford has some work arounds.

I installed one of these catch cans on our truck. So you have to empty it every now and then. No big deal. I had one on both of my previous V8 cars. My G8 GXP and my Corvette. With the amount of oil that fills up in there, it's pretty amazing to think that was getting sucked back into the intake.



I'm really excited about the 2017 Ford Raptor which is suppose to have an ecoboost variant.

Question, is it true the Ecoboost needs premium fuel? My Audi S4 had a turbo and it was loads of fun, but the premium got old fast. Granted this was back in 2012 when prices were much higher.

Nope 87 octane is good. No premium requirement.

Yes it runs fine on regular, however, Ford suggests using a higher octane when towing for better performance. It does seem to perform better and actually get better mileage with the higher octane, especially in the mountains. But there are so many variables when towing with grades and wind that I really do not concern myself with analyzing mpg.

Above comments re regular apply to existing production of the 3.5 litre Ecoboost with 320 to 365 hp. Next year the Raptor gets a new version with significantly more hp, so premium is more likely to make a difference. The GT gets even more hp (600?) so premium will almost definitely be required. The 4 cyl 2.3 Ecoboost at up to 350 hp has a much higher specific output than the current 3.5, so it gives us some idea of the potential of the basic design.

Well, I own a 2016 extended van with the eco boost. I do have a problem and that is I forget I a towing a trailer in 30 + winds. I also forget that I am well over the speed limit occasionally. I was a diesel mechanic for 20 years and knew this is the way to go.
25 AS and van fully loaded even with full size washer and 7000 generator.
This puppy will stand up to anything from the start. I have had much fun with it. Will use cruze control from now on so not to kill myself.
When I back it up to do laundry, it looks like one unit.

From the 2015 Ford F150 Manual:

2.7L and 3.5L EcoBoost Engines
We recommend regular unleaded gasoline with a pump (R+M)/2 octane rating of 87. Some stations offer fuels posted as regular with an octane rating below 87, particularly in high altitude areas. We do not recommend fuels with an octane rating below 87.
To provide improved performance, we recommend premium fuel for severe duty usage, such as trailer tow.

Yes, recommended but not required.

We have a 2013 F150 with the 3.5l Ecoboost. I love the engine and the power along with the transmission. Fuel mileage sucks with towing but that is in part because I don't have to slow down due to a lack of power.

We have had a lot of brake problems as has my son with his similar '13 F150. This is not because of towing but bad calipers, crappy dealers and Ford Motors nonexistent customer service. Very frustrating after dealing with good auto companies and dealers in recent years.

The other big negative with our F150 has been Sync. I'll take BMW's iDrive or similar any day of the week over a touch screen based system. As others have said, the voice command system is like playing a game of 20 questions with a drunk toddler. Sad.

Hi, my 2014 F-150 Ecoboost has about 25,000 so far and no drivability issues. Out of that, over 13,000 miles was towing. This was all in one trip. I believe that some of the shuddering was on the longer wheel base models. Mine is a 145" model with a single drive shaft and the 157" wheel base models have a two piece drive shaft. To date, I haven't tried Premium fuel yet. Supposed to add 20 horse power and 10 lbs torque.

This may be true, however my 2011 with 145" wheelbase and 60000 miles, half while towing, has had the shudder several times. As noted in my previous post, Ford installed the shielding fix, and then 2 coils and spark plugs. Altogether it has happened 4 different times. No problems when burning premium on my last 5000 mile tow in wet and humid conditions.
I hope on the 2016 that I'm picking up tomorrow that Ford has fixed the problem.

Hi, I should have mentioned that the shuddering from vehicles that have two piece drive shafts, Is at take off or slow speeds. It is stated to be worse when towing. This is completely different than engine shuttering.
