longevity of the 3.5L ecoboost engine
Hello everyone - We were having such a hard time deciding on a new tow vehicle that we ended up renting a 2015 F-150 with the 3.5L ecoboost for a camping trip last week. So we got to try it actua...

Ford had little idea of Ecoboost longevity beyond a few high mileage track tests out to warranty periods, and considered the first buyers to be the test drivers for the technology.
For the 3.5 Ecoboost, it has actually done pretty well with part time towing, running out to over 200,000 miles now. Ford has been adjusting the engine build based on in-service experience, so you can expect to do better than the first Ecoboost customers.
The 3.5 V-6 was already obsolete (3.7 replacing it) when picked for turbocharging and beefed up for the loads. The idea was, if it worked, they would develop a replacement engine designed from ground up for boosting. The interim choice has done so well that Ford is keeping it now.
Not so for some of the early 4 cylinder Ecoboost, where an older engine was picked for the turbo experiment. Most of those applications are now seeing new smaller, lighter 3 and 4 cylinder engines that were designed to be turbocharged only, with no normally aspirated versions used. Much like with turbo diesels, which started out as "let's put a little boost on this old thing" to be replaced by a heavily boosted engine of smaller displacement and more cutting edge engineering of internals, newer materials technology.
