Step-by-Step Instructions
Follow these steps carefully
1
Confirm oil and filter fitment
The 2021-2024 Bronco's 2.3L EcoBoost takes 6.2 quarts of 5W-30 meeting Ford WSS-M2C961-A1. It uses a Motorcraft FL-910S spin-on filter and a 15mm drain plug behind a skid plate. Park on level ground with the engine warm.
🔧 Mechanic's note — Tom Becker
I never just grab any 5W-30 for this engine — it needs the Ford WSS-M2C961-A1 spec. The EcoBoost runs hot and the turbo cooks cheap oil into sludge. The spec is printed on the back of the jug; I check it before buying.
2
Raise and secure the vehicle
Set the parking brake and chock the wheels. The Bronco's clearance allows access underneath; if you lift it, use the frame points and jack stands — never jack alone. Remove the four 15mm skid-plate bolts to expose the drain plug.
3
Drain the old oil
Remove the oil fill cap to vent the crankcase. Position the drain pan under the oil pan, remove the 15mm drain plug, and drain the oil fully. Wipe the plug and pan flange clean.
4
Replace the filter
Unscrew the FL-910S filter, reached over the front tire area. Confirm the old gasket came off. Oil the new gasket, thread it on by hand until seated, and tighten per the box. Refit the drain plug to the manual's torque.
🔧 Mechanic's note — Ray Delgado
Keep that filter upright as you unscrew it. The FL-910S sits sideways over the tire area, and if you tip it, hot oil runs down your arm and all over the frame. Ask me how I know.
5
Refill and check for leaks
Refit the skid plate. Add about 6 quarts of 5W-30, wait a minute, then top up to the full mark — 6.2 quarts total with the filter. Run the engine briefly, shut it off, and check for leaks.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Using the wrong viscosity, specification, or filter
- • Raising the vehicle without rated stands, ramps, and wheel chocks
- • Forgetting the old filter gasket or reusing a crushed drain-plug washer
- • Over-tightening the filter or drain plug and damaging the housing or pan
- • Checking level on an uneven surface or overfilling after a partial drain
