Should I buy an Ecoboost F150 w/ over 100k miles??!

In your price range you could get a nicer 5.0 with fewer miles than that. I'd certainly go that route myself. You could have a nice truck. Although I think you should be able to find a 'boost with fewer miles for 25k. If you don't know it's owner and its history, you are potentially buying a bag of foul smelling worms.
 
The thing is, the ecoboosts are EXTREMELY sensitive to poor oil quality or having oil change intervals that were too long. Some have some oil dilution issues. Couple that with poor oil or longer oil changes, and it's a disaster. If you don't know the history, I'd assume it wasn't cared for properly and move on.


This coming from a fella who loves his boost.
 
And frankly, that is no different than any vehicle. If the owner didn't care to change the oil you could have a problem. Lots of owners pay every penny they have to own the right ride. That doesn't mean they take care of them. Lots of other owners are barely capable of caring to put gas in on a regular basis, much less oil and services.

Good point on the service history, but even a person that is diligent doesn't necessarily keep receipts for a long time. I do, but it really doesn't do me any good at trade/resale time anyway.

There are a couple handfuls of known blown ecos on here. Most of those were tuned. There have been about 3/4 of a million ecos sold. That is a pretty small percentage. If yours blew, it blows. No question about that no matter the situation tuned or not. But, that doesn't mean they all have issues beyond any other vehicle.
Well, yes and no. These seem to be particularly sensitive to extended oci. I have a 460 that has seen many many way too long intervals lol. With the oil dilution possibility (being direct injected) and the timing chain, I feel like these are more sensitive than a lot of other motors to proper service intervals.

But of course any used vehicle could have problems.

But, for example, if I was buying a 7.3 powerstroke with many miles I wouldn't be as paranoid about the servicing it had had.
 
I was just throwing out trucks that I've gas personal experience with. I was very hard on them. Due somewhat to ignorance and somewhat to tight finances.

I'm not really disagreeing with you. Any used vehicle is of course a crap shoot. I just think some more than others.

I'm sure it's getting continually worse with new technology.
 
My '15 xlt has heated seats, remote start, Bluetooth, 8" touch screen, keypad entry, backup camera, trailer assist, heated mirrors, I don't know what else I could even use. Lol


But i didn't know if '14- xlts were so equipped.
 
Lol. The OP has been informed of the potential issues.

The EB is a fantastic half ton ride. You are now a well informed buyer. Go in with your smarts in place and make a wise decision with what you now know. You should be fine.
 
My last truck was an f250 I bought for $8000 with 200k miles. Drove it for 8 years and sold it for $5500 with 335k miles. Couldn't beat that with a stick! I still had a payment tho. But it was small and was paid off in about 2.5 years.
