None of the vehicles I have owned to this point have called for a 0W-20 oil. And I just don't see how a less than 20 wt oil can be a good thing for engines. To each his own I guess. With all these thin oils, I have to wonder about potential timing chain issues down the road.
215K on the 2007 Fusion at 10K OCIs with no timing chain problems.
Not surprised, that 2.5L is a mature, and proven design. API SN is probably extreme overkill lol
