Says who? Certainly not Ford. The Focus (base) is a 2.0 DI engine that specs 87. The DI 1.5/1.6/2.0 Turbos in the Fusion/Escape/Explorer/Taurus spec 87 although "run better on 91". Both my Ecoboost 3.5's are fed a diet of 87 and run just fine. 87-93 will perk them up a little better, especially in the heat but they run great on 87, especially in the winter. And the F150 works - tows a 9k+ travel trailer.Typically when direct injection gets added to a car then 93 octane becomes a requirement.
