⚠️ Safety & Precautions

• ⚠️ Work on a cool-to-warm engine, not a hot one. Hot oil can burn skin.
• ⚠️ Support your Mustang with jack stands before going underneath. Never rely on a floor jack alone.
• ⚠️ Keep oil off the exhaust and belts. Wipe spills before starting the engine.
• ⚠️ Used engine oil is hazardous waste. Store it in a sealed container and recycle it properly.
• ⚠️ Battery disconnect is not required for this oil change.

📋 Before You Begin

• 🅿️ Park your Mustang on level ground and set the parking brake.
• 🧱 Place wheel chocks behind the rear wheels to stop the car from rolling.
• 🌡️ Run the engine for 2-3 minutes if it is cold, then shut it off. Warm oil drains faster.
• 🧰 A torque wrench is a tool that tightens bolts to an exact tightness so they are not too loose or too tight.
• 🛢️ An oil filter wrench grips the round oil filter so you can loosen it if it is too tight by hand.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and Secure the Front of the Car

• 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 car gently onto the jack stands.
• Give the car a light push to confirm it is stable before going underneath.
• Never crawl under a jack-only car.

Step 2: Remove the Oil Fill Cap

• Open the hood.
• Use your hand to remove the engine oil fill cap on top of the engine.
• Set the cap somewhere clean. This helps the oil drain smoothly.

Step 3: Position the Drain Pan

• Put on safety glasses and nitrile gloves.
• Slide the oil drain pan under the oil drain plug at the bottom of the oil pan.
• Make sure the pan is slightly forward of the plug because oil may shoot outward at first.

Step 4: Drain the Old Engine Oil

• Use a 15mm socket and 3/8-inch drive ratchet to loosen the oil drain plug.
• Finish removing the plug by hand while pressing inward slightly, then pull it away quickly.
• Let the oil drain until it slows to an occasional drip.
• Use shop towels to clean oil from the drain plug area.
• Keep your hand above the oil stream.

Step 5: Reinstall the Drain Plug

• Install a new drain plug sealing washer on the drain plug.
• Thread the drain plug in by hand first to avoid cross-threading.
• Use a 15mm socket and 3/8-inch drive torque wrench to tighten the drain plug.
• Torque to 28 Nm (21 ft-lbs).

Step 6: Remove the Old Oil Filter

• Move the oil drain pan under the oil filter area.
• Use an oil filter wrench to loosen the old oil filter if it is too tight by hand.
• Spin the filter off by hand slowly. Oil will spill from the filter.
• Make sure the old rubber gasket came off with the old filter.
• Use shop towels to wipe the filter mounting surface clean.
• A stuck old gasket causes leaks.

Step 7: Install the New Oil Filter

• Dip a clean gloved finger into fresh 5W-20 full synthetic engine oil.
• Lightly coat the rubber gasket on the new engine oil filter.
• Thread the new oil filter on by hand until the gasket touches the engine.
• Tighten it by hand another 3/4 turn after gasket contact.
• Do not use the oil filter wrench to tighten the new filter unless the filter instructions specifically require it.

Step 8: Refill with Fresh Oil

• Place a funnel in the oil fill opening.
• Pour in about 9 quarts of 5W-20 full synthetic engine oil first.
• Reinstall the oil fill cap by hand.
• Use shop towels to wipe any spilled oil.

Step 9: Start the Engine and Check for Leaks

• Start the engine and let it idle for 30-60 seconds.
• Do not rev the engine.
• Look underneath with a flashlight and check the drain plug and oil filter for leaks.
• Shut the engine off.

Step 10: Check and Top Off the Oil Level

• Wait 5 minutes so the oil can drain back into the oil pan.
• Pull the dipstick, wipe it clean with shop towels, reinstall it fully, then pull it again.
• Add oil through the funnel in small amounts until the dipstick reads full.
• Your Mustang typically takes about 10 quarts with filter, but always final-check by dipstick.

Step 11: Lower the Car

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

Step 12: 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 has reset to 100%.
• If your screen layout differs, use Settings > Advanced Settings > Vehicle > Oil Life Reset.
