Mine is a 2013 ecoboost 2L. First I used 87. Then went back to 93. Engine much quieter, no downshift uphill. I don't mind the 20cents. My tank doesn't hold that much and I do get 1.8 avg mpg n town and 3 on hwy according to trip. I think a lot depends on how u drive. I don't get on mine, don't have to. Pass on two way Hwy easy w/o much more pressure enough 4 turbo kick n.
