What size socket is the oil drain plug on a 2016 Ford f150?
The oil drain plug on a 2016 Ford F-150 typically requires a 14 mm socket.
Across the 2016 F-150 lineup—whether you’re driving a 2.7L EcoBoost, a 3.5L EcoBoost, or a 5.0L V8—the drain plug head is generally a 14 mm hex. If a drain plug with a different head has been installed (for example by a previous owner or due to an aftermarket oil pan), it’s not the standard Ford part. When in doubt, inspect the plug head and confirm with the owner’s manual or a dealer/service data source.
Engine variants and the standard hardware
Ford tends to use the same 14 mm hex head for the oil pan drain plug across the common engines in the 2016 F-150. This makes finding a compatible socket straightforward for most drivers. If your plug looks non-standard, do not force a socket onto it; verify the correct size before attempting removal.
How to verify the size on your truck
To be certain, consult the vehicle’s owner’s manual or the official Ford service data for your exact engine. If you’re at the truck, you can try fitting a 14 mm socket first; if it doesn’t fit, stop and check, as there may be a different size or a replacement plug. When in doubt, contact a Ford dealer or a trusted repair shop for confirmation before draining the oil.
Summary
In short, the default oil drain plug size for a 2016 Ford F-150 is 14 mm. Always verify against the manual or the plug itself before removal to avoid damaging the bolt head or threads.
