My dad just bought a used 2015 F150 with the 2.7L EcoBoost. Will mostly be a second vehicle for him and something to put an ATV in the back or pull a side-by-side on a utility trailer. I'm reading the Owner's Manual and finding Ford is only mentioning 5W30 API SN - nothing past that. Since this engine takes 6 quarts exactly, it seems like this would be a good candidate for the 6-quart Havoline Box? First EcoBoost engine in the extended family.
