Who has the highest mileage Eco Boost?

[trunk monkey]

Getting ready to buy a 2017 Limited....my previous Ford was a 2003 F-150 with the 5.4 triton. When I sold it, it had 280,000 miles on it, and drove like a new engine. So I'm a big fan of the V8's, and am a little curious how the Eco Boosts have faired so far. Thanks in advance for any insight.

You'd be better off visiting the F150 forum if youre inquiring about high mileage reliability, simply because the ecoboost has been around in the trucks since 2009.

I have 24,455. 2016

I have a F-150 XLT with the V-8. I tow my hunting trailer with it and it was a lot better than my 2006 F-150 XLT with the small V-8. My 2017 Ford Expedition Limited has the ecoboost v-6. I'm impressed so far with the power and the mileage. I don't plan to haul with the Expedition but can if need be.

Agree with 07xln as ecoboost has been in F-150 since 2011, it's only been here in the expys since 2015. They are a pretty reliable platform. I prefer the bigger displacement motors but you have to give them credit they are good powertrains.

Only 38k miles, so not in the running.

we need to tow about 5000lbs if we get the expedition, but very short distances, maybe two miles to the boat ramp and back.

Ford has sold over a million 3.5L EcoBoost engines and there are many of them out there with well over 100,000 miles on them. I would say you have nothing to worry about. I'm loving mine but I only have 6600 miles on mine.

I wouldn’t hesitate for a second to buy one with the EcoBoost motor. It’s a solid platform that will pull your boat no problem.

I have 75,000 miles on my 2015. Just changed the spark plugs today for the first time cause I’ve had a miss and rough idle. Fixed it. No other problems so far. I’ve only owned it for less than a year tho

Pretty easy plug change? Which ones did you end up using and what gap?

 

[Muddy Bean]

It was easy...worst part of it is my ratchet driver slipped and I broke the handle off my oil dipstick...so now I’m trying to figure out how I’m going to get it out to replace it [emoji51]

I used the FoMoCo SP-534 plugs. I gapped them to .030. The old ones were way more than that...

Those are some pretty good looking plugs from what I can see(I really like to see the band at the bottom of the porcelain) for a Turbo engine with 75K. You can see the ash from the additives in the fuel package on the plug electrode but zero carbon in the fire zone, zero evidence of detonation or lean-burning.....overall, I'd say your engines is in pretty decent shape Muddy. A bit of TB cleaner might have been warranted prior to swapping the plugs but you know what you're doing.....

Mine just turned past 35K over the weekend.....

My '11 Expy has the v8.
My '15 Transit 250 (work van) has the Ecoboost. 77k miles and still flawless.

I too wonder about the longevity of the turbo engine. Will they be reliable to 300k like the v8s?

 

[deweysmith]

The gap gets bigger as they are used, that’s what wears them out. The gap is set to allow the electrode to burn away and still maintain spark.

One thing to consider. A engine that works harder and and turns more RPMs, will fail sooner. To produce "V8" power the EcoB, revs higher than Trition 5.4l. Running it on "boost" is adding another element of stress to the mix. The modest fuel savings, does not make it, that appealing.

Incorrect, forced induction motors do not have to rev higher. The primary wear is the higher cylinder pressures. That being said I don't wish to argue, but that statement is not correct.

Here we go...I did not say they "have" to rev higher. The V6 must rev higher to produce V8 power. What the hell, is cylinder pressure wear? The original thread asked if a EcoB will be reliable as the 5.4l.

I don't have it in me to get involved in this battle again. I got hit with to much shrapnel last time

Hmmm not .028? A lot of what I have read says they should be .028

**edited**
Looks like .028 for tunes
