Here's the link to the F150 forum with the guy having over 300,000 miles on his ecoboost F-150. He gave it to his son when it had 366,000. You can read through the thread to see he tows 85% of the time and the only thing I saw he did more often than the owner's manual recommendations is change his spark plugs every 50,000. No oil catch can no induction cleaning. http://www.f150ecoboost.net/forum/6-f150-ecoboost-chat/28082-300-000-miles-my-2011-eco-boost.html Also while researching if I require an oil catch can. I found this article from 2011 at Edmunds, a site I have used often over the years, heck even when it was in book form pre-internet. It talks about the early adopters of GDI and how now (2011) many of the issues have been eliminated. https://www.edmunds.com/autoobserve...33&utm_term=2470763_VigLink&mktcat=affiliates I have decided to simply do the maintenance as recommended by the owner's manual with the exception of changing the plugs every 50,000 miles.
