Interesting. And my objective opinion...
My wife has a 2014 ford fusion titanium 2.0T. I change the oil etc. Each time i change it on the ff, as mean it may sound
the finish on the oil pan, transmission etc. reminds me of my lawn mower.
Next gas mileage, they claim 34 mpg i think on the hwy. even with her best driving she can barely get 32. My 335i gets more than 33 on the hwy.
