2018 Ford Focus Oil Capacity

The 2018 Ford Focus oil capacity depends on the engine: the 1.0L EcoBoost takes 4.9 qt, while the Duratec 20 takes 4.5 qt. Both listed engines use 5W-20 oil. Match your vehicle’s engine to the capacity shown rather than treating one figure as universal for every Focus.

Read the listed capacity as the engine’s oil amount and the viscosity as the specified oil grade. These figures distinguish the two engines for this model year; they are not interchangeable simply because the oil grade is the same. The facts provided do not specify whether a capacity includes an oil-filter change, so confirm that detail in the owner’s manual. If your engine or required amount is not listed, check the door jamb or owner’s manual for the correct information.
