My mom has the 2.0EB in her Fusion and absolutely loves it. Even when I drive it and am used to my Mustang, the power is great for the car. There is minimal turbo lag and when the power does hit, it isn't like my 04 Volvo S60R that would snap your head back and break the tires loose. More of a controlled power application thing.
The 2.7EB is a very strong engine, it has a weak point where the oil pan leaks though. We haven't seen many recently, but had a clump of them, to get it to stop leaking you have to leave it on a lift with the pan off overnight, then put on a new pan and wait a day to add oil for the RTV to cure. I think we had an early one where we did injectors, but I think that was mostly a tech pulling out the parts cannon.
I know it isn't the recommended by Ford thing, but I use Mobil 0W40 in my mom's Fusion and have it changed every 5K miles. I would do it myself but there is a huge under car shield thing that I hate dealing with on my back on jackstands, so I have one of the techs I trust do it. She is just over 30K miles so I will do the spark plugs soon since that is about when we start seeing misfire codes for the plugs being blown out.
