🔧 Focus - Engine Oil & Oil Filter Change

On your Focus, you’ll drain the old engine oil, replace the oil filter element, then refill with the correct 5W-20 oil. This keeps internal engine parts lubricated and helps prevent wear, sludge, and overheating.

Difficulty Level: Beginner | Estimated Time: 0.8-1.5 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front of the car

• Use floor jack (rated 2-ton minimum) to lift at the front center jacking point.
• Place jack stands (pair, rated 2-ton minimum) at the approved front support points and gently lower the car onto them.
• Give the car a small push to confirm it’s stable before you go underneath.

Step 2: Remove the lower splash shield (if equipped)

• Use a trim clip tool and flathead screwdriver to remove the plastic push clips/screws holding the lower engine cover.
• Set the clips aside so you don’t lose them.

Step 3: Drain the engine oil

• Position the drain pan (8-quart minimum) under the oil pan drain plug.
• Use a 15mm socket and 3/8" drive ratchet to loosen and remove the drain plug.
• Let the oil drain until it slows to an occasional drip (typically 5–10 minutes).
• Wipe the drain plug area with shop rags.

Step 4: Reinstall the drain plug

• Install a new oil drain plug gasket/washer on the plug (if separate).
• Thread the drain plug in by hand first to avoid cross-threading.
• Use a torque wrench (10–50 Nm range) with a 15mm socket and Torque to 28 Nm (21 ft-lbs).

Step 5: Replace the oil filter element

• Find the oil filter housing in the engine bay (a plastic cap-style housing).
• Use a 27mm socket with a 3/8" drive ratchet to loosen the filter cap slowly.
• Pull out the old filter element and let it drip into the drain pan.
• Remove the old O-ring(s) from the cap using your fingers (avoid scratching the plastic).
• Install the new O-ring(s) (lightly coat them with fresh oil using a gloved finger). This prevents pinching and leaks.
• Push the new filter element into place (it snaps/presses onto the cap on most designs).
• Reinstall the cap by hand, then use the torque wrench (10–50 Nm range) with the 27mm socket and Torque to 25 Nm (18 ft-lbs).
• O-ring = a rubber sealing ring.

Step 6: Reinstall the splash shield

• Reposition the shield and reinstall fasteners using the trim clip tool and flathead screwdriver.

Step 7: Refill with new engine oil

• Lower the car from the stands using the floor jack (rated 2-ton minimum).
• Insert a funnel into the oil fill opening.
• Pour in 5.5 quarts of 5W-20 first (don’t dump all 6 quarts immediately).
• Reinstall the oil filler cap.

Step 8: Start, check for leaks, and verify level

• Start the engine and let it idle 30–60 seconds.
• Turn the engine off and wait 3–5 minutes for oil to drain back to the pan.
• Check underneath for leaks around the drain plug and filter housing.
• Check the dipstick and top off as needed (typically ends up around 5.7 quarts total with filter).
• Use shop rags to wipe any spilled oil.

Step 9: Reset the oil life monitor

• Turn ignition ON (engine OFF).
• Use the steering wheel buttons to navigate: Settings > Vehicle > Oil Life Reset
• Select and hold OK to reset to 100%.
