I've been reading articles on various sites that keep talking about Ford's "2nd generation" EcoBoost engines. Specifically that the 2.7L and 3.5L engines now have both direct injection AND multi-port injection, thereby preventing carbon buildup on the back of the intake valves. But... I have not found concrete proof. Has anyone seen/read/heard anything definitive? I'd like to think that my 2017 Fusion Sport has the latest engine technology, especially when dealing with the carbon buildup (which I'm still not sold on is a real problem if one uses proper oil).
Thanks.
Thanks.
