Topic: Mustang EcoBoost Manual

[Sir Osis of Liver]

I checked the CR reliability for the 2.0L in the Fusion and Focus ST, which are more closely related to the 2.3 in the Mustang. Both engines are "much better than average" according to CR.

So, I'll stick with those engines being pretty reliable.

You can find issues with pretty much anything sold by doing internet searches. The only way to filter the signal to noise ratio is by looking at something like Consumer Reports, or JD Powers. Even then, it's self reported information, so problems tend to be amplified. Happy consumers aren't as motivated to report, as pissed off consumers.

Was curious how much more you have to pay to get the V8.

EcoBoost Performance Package: $33,099
GT Performance Package: $42,799

That's a huge difference. Almost $10k! And I think they are otherwise very similarly equipped.

C'mon Man.  A wiper issue v.s. an engine failure.  Which is worse.

But was it one engine, ten, 100.....thats the thing, in a mass production scheme a handful of failures among millions of products that have no issues is not really concerning. As Sir O said, broken valves will kill an engine and if that wiper motor starts on fire in an attached garage, thats a serious problem....again though, 1 or couple of hundred thousand issues.

He said that the Ecoboost motors had been around for 6 years and were reliable.

He was wrong.  And now he wants to talk about Corollas (apart from the Nürburgring version).  I get it - all cars have issues and recalls exist and I never said Corollas or Tundras were reliable.  But his comment about the Ecoboost motors being reliable is factually incorrect.

I haven't heard of any other issues except for that intercooler problem on them either. Anyways, I don't know, CR says they are fairly reliable, I would have no reason to doubt them.

Actually CR data backs up my claim. The Ecoboost engines in the F150, Focus ST, Fusion have been either better than average, or much better than average as far as reliability.
Data for the Flex and Taurus SHO is pretty spotty, but the most recent years, they are also much better than average.

JD Power 3 year dependability survey (which can be skewed easily) had Ford at 188 problems per 100 vehicles compared to the industry average of 147.

Yes, sorry, I guess those engines are pretty reliable:  http://partsblog.olathetoyota.com/4383/ford-sued-ecoboost-problems/

You don't buy a brand, you buy a model of a particular brand. For the Fusion, it's predicted reliability is "better than most".

Also, that link from a Toyota blog is just reiterating the same suit that was addressed by the NHTSA about condensate in the intercooler. It's only an issue if you don't get it fixed.

IIRC Ecoboosts use a sensor for fuel octane rating to run different fuel maps, in which case it isn't going to be knocking either.


Ford uses what every other manufacturer installs in all their motors; knock sensors.  Here is how it works.    The motor starts "knocking" due to, in this instance, lower than needed octane, the knock sensor picks this up and detunes the motor by retarding the timing.

However, the motor is always in and out of knock because the knock sensors are constantly been switched on and off.  BMW advises owners that use of 87 octane is only a last resort/temporary situation.

You will see no signage on an Ecoboost indicating that the motor is designed for 93 octane.  It's such BS.

Everybody knows how knock sensor work. 

I'll let you in on a little secret. Every car runs so lean now, that every car will be hitting the bounds one way or the other due to air moisture content or the lack thereof, altitude and temperature.

Every brochure that quotes the HP and torque figures has a note that specifies "on 93 octane fuel" and the owners manual states that 93 octane is recommended for maximum performance.

You're just jealous that the most exciting announcement from Toyota lately is the Corolla Nürburgring edition. 

An new best post of 2015

Ya, if one has the $$$ that V8 is great.  No question.  Oddly, Ford uses the same transmission as the V6.   

Being a member of peasant class, I'm finding the V6 vert, 6 manual, with 51A (18s plus P/seat) and 3:55 rear LSD pricing so reasonable.  $1000 Costco rebate/incentive currently.  $31,600.  with $1000 dealer discount excluding HST.   0%/60 even.  I dunno. 

You could put 255s on the rear and save the stock 235s for the next set of fronts.  You could easily install a Steeda rear sway bar and better bushings and finally this

all for $1K

$31k for a 300hp convertible with a proper manual transmission and rear wheel drive is a great deal.....I didn't think you could get lower gears or an LSD on the V6.

All Mustangs come with a clutch style LSD which is critical for snow if applicable.  Standard ratio is in the low 3's.  The GT  (ONLY with the PP) gets the Torsen either 3:73 or 3:55

Ecoboosts have been around 6 years now. So far they have been reliable. No reason why this one would be any different.

Wait, what?

You should read your link:

After receiving several hundred complaints relating to Ford’s F-150 trucks equipped with an EcoBoost engine suddenly and unexpectedly shuddering, shaking violently, stumbling, misfiring, rapidly losing power, or going into limp mode while a driver is operating the vehicle, the NHTSA launched an investigation. Tests conducted as a result of that investigation traced the problem to condensation in the intercooler. That condensation can result in water being pulled into the engine, which can cause cylinders to misfire. The NHTSA found that a proposed fix by Ford corrected the problem in the F-150s.

You should read the second link sent.  Use some Google Fu on the failures of these motors as I am not going to do it for you.  You might learn a thing or two given you said that the motors "have been reliable."

Hey I have one of these motors and have had 0 issues so far....would definitely buy again.

My BIL's dad bought a new ecoboost F150 (he's a ford) and hates the ecoboost. Horrible fuel economy based on what he was promised/expecting and lots of issues.

Don't have an angle on this debate, just passing along the only personal experience I have.

N of 1, but certainly those arguments against the F150 have been a common refrain on this forum (and automotive chatter in general). My question is, are some buyers unhappy because of the EcoBoost's "issues" (reliability, AP's shudder troubles, etc.).  Or are they unhappy because Ford oversold the benefits (primarily fuel economy benefits), but the engine underdelivers? 

I wonder if the EcoBoost economy ratings were closer to what people can reasonably expect to achieve, would they still complain about the engine?  It seems pretty obvious to us on the forum, if you use a boosted engine to produce V8+ HP/TQ (drive hard, heavy towing, etc.), you're gonna get V8+ fuel economy...but are most consumers aware of that?

[Fobroader]

The whole idea of V8 power and V6 fuel economy intrigued me....but, Audi tried that with their I5 many years ago and it didn't have the power of an 6 cylinder nor did it get nearly as good of mileage as a 4 banger. What Sask said....if its making the same power as a V8, its working hard, therefore it will use a lot of fuel.

I must be getting old...someone please explain to me why fuel economy get peoples Lu Lu's in a knot when buying a sports car?

I'm confused about that as well.....

Indeed. If I'm in the market for a Mustang it sure as hell is not going to be a turbo 4. Its got to be V8 or bust.
