📋 Before You Begin

• Park your Mustang on level ground and set the parking brake.
• Place wheel chocks behind the rear wheels.
• Run the engine for 2-3 minutes if it is cold, then shut it off. Warm oil drains faster.
• Open the hood and remove the engine oil fill cap. This helps the oil drain smoothly.
• A torque wrench tightens bolts to a measured tightness so they are not too loose or too tight.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Support the Front

• Use the floor jack at the front center jacking point or approved front lift point to raise your Mustang.
• Place jack stands under the approved front support points.
• Lower the vehicle gently onto the jack stands using the floor jack.
• Shake the vehicle lightly by hand to confirm it is stable before going underneath.
• Go slow and stay safe.

Step 2: Remove the Lower Access Panel if Equipped

• Use the plastic trim clip remover to remove any push clips holding the lower splash shield or access panel.
• Set the clips and panel aside in order so they go back in the same places.
• If your Mustang has a direct access opening for the drain plug and filter, you may not need to remove the full panel.

Step 3: Position the Drain Pan

• Put on safety glasses and nitrile gloves.
• Place the oil drain pan under the engine oil drain plug.
• Move the pan slightly toward the rear of the vehicle because oil may stream outward at first.

Step 4: Drain the Engine Oil

• Use the 15mm socket and 3/8-inch drive ratchet to loosen the engine oil drain plug.
• Remove the plug by hand once it is loose, keeping light inward pressure on it until the final threads release.
• Let the oil drain until it slows to a drip.
• Inspect the drain plug and gasket. Replace the gasket or plug if damaged.
• Reinstall the drain plug by hand first to avoid cross-threading.
• Use the torque wrench with the 15mm socket to tighten the drain plug to Torque to 27 Nm (20 ft-lbs).

Step 5: Remove the Oil Filter

• Move the oil drain pan under the oil filter area.
• Use the oil filter wrench to loosen the oil filter by turning it counterclockwise.
• Spin the filter off by hand once loose.
• Keep the open end facing upward as much as possible to reduce spills.
• Check that the old rubber filter gasket came off with the old filter.
• Two gaskets can cause leaks.

Step 6: Install the New Oil Filter

• Use a clean gloved finger to spread a thin film of fresh 5W-30 oil on the new oil filter gasket.
• Thread the new oil filter on by hand until the gasket contacts the mounting surface.
• Tighten the filter by hand an additional 3/4 turn after gasket contact.
• If using a torque-style filter tool, tighten the oil filter to Torque to 16 Nm (12 ft-lbs).
• Do not overtighten the filter. It can crush the gasket and cause leaks.

Step 7: Reinstall the Lower Panel

• Use the plastic trim clip remover by hand to align the lower splash shield or access panel.
• Reinstall all push clips by pressing them fully into place.
• Confirm the panel is secure and not hanging near the exhaust or moving parts.

Step 8: Lower the Vehicle

• Use the floor jack to raise the front slightly off the jack stands.
• Remove the jack stands.
• Lower your Mustang slowly to level ground with the floor jack.

Step 9: Refill the Engine Oil

• Place the funnel in the engine oil fill opening.
• Pour in about 5.3 quarts of 5W-30 full synthetic engine oil first.
• Reinstall the oil fill cap.
• Start the engine and let it idle for 30-60 seconds.
• Shut the engine off and wait 5 minutes so oil drains back into the pan.
• Use the dipstick to check the oil level. Add oil in small amounts until the level reaches the full mark.
• The total fill is approximately 5.7 quarts with filter.

Step 10: Reset the Oil Life Monitor

• Turn the ignition on without starting the engine.
• Use the steering wheel controls to open Settings > Vehicle > Oil Life Reset.
• Press and hold OK until the display confirms the oil life is reset to 100%.
• If your display layout differs, use the steering wheel controls to find Settings > Vehicle Settings > Oil Life.

• Top off with 5W-30 full synthetic oil if needed, but do not overfill.
