The 2013 Ford F-150 with a 3.5L EcoBoost engine uses the Motorcraft FL-820-S oil filter.
Ford’s official documentation and parts catalogs consistently list FL-820-S as the standard spin-on filter for the 3.5L EcoBoost in that model year. If you prefer aftermarket options, you can choose a reputable equivalent that matches the same thread and gasket design, or confirm fitment with the retailer using your vehicle’s year, make, and model.
Part number and compatibility
The Motorcraft FL-820-S is the designated OEM filter for the 3.5L EcoBoost F-150 in 2013. It is a standard spin-on oil filter that Ford has used across several of its gasoline engines, and it remains available through Ford dealerships and major parts suppliers. When selecting a filter, ensure it is specified for the 3.5L EcoBoost and for Ford F-150 models from that era, to ensure proper sealing and filtration.
Aftermarket cross-references
Many reputable aftermarket brands offer cross-referenced filters that substitute for the FL-820-S. If you opt for an alternative, verify the product listing clearly states compatibility with the 2011–2014 F-150 with the 3.5L EcoBoost, and check reviews or retailer guidance to confirm proper fitment for your specific engine and year. If in doubt, bring the old filter to the parts counter or use your VIN to double-check compatibility.
Maintenance tips
Use the filter as part of a regular oil change interval recommended by Ford (typically with the 5W-20 oil specification for the 3.5 EcoBoost, though local climate conditions may warrant adjustments). Replacing the filter at every oil change helps protect the engine from particulates and ensures proper oil flow and lubrication.
Summary
For a 2013 F-150 with the 3.5 EcoBoost, the recommended oil filter is the Motorcraft FL-820-S. If you shop aftermarket, look for a filter that explicitly cross-references to FL-820-S and is marked compatible with the 3.5L EcoBoost in this model year. Always confirm fitment via the retailer using your vehicle’s details or VIN to ensure a correct seal and filtration performance.
