When you head to the auto parts store, you can simply ask them how much oil you need based on your F-150 model year and engine size. If you want to order the oil online, you’ll need to do your own research.
If you have an EcoBoost engine—which is generally a 2.7-liter or 3.5-liter engine—you will need at least 6.6 quarts of oil. However, if you have a V-8, you generally need at least 8 quarts of oil. Consult your owner’s manual if you have an older model, as these amounts may change if you have an F-150 that’s more than 20 years old.
