I have a 2014 ford fusion with the 2.5 non turbo engine. It only has 20500 miles on it, and it has had 5-20 QSUD since the factory oil was drained out at about 4000 miles. I change oil spring and fall if it needs it or not, as it gets a lot of short trips. As you can tell it doesn't get a lot of miles on any one oil change. And I have been changing the filter every time. At first I used the motorcraft filters, but las couple times I went to fram TG. I have a couple cases of Mobil 1 full syn that is 0-30. I am thinking that it would be good to put in for my spring change next month to run through the summer, then in the fall go back to the 5-20 Quaker. What do you all say??
