1. Gather Your Supplies:
* New oil: Consult your owner's manual for the correct type and quantity (typically around 5-6 quarts of 5W-20 or 5W-30).
* New oil filter: Again, check your owner's manual for the correct filter. Auto parts stores can help you find the right one if needed.
* Oil filter wrench: Choose the correct type for your oil filter (cap type or strap type).
* Wrench for drain plug: Usually a 13mm or 15mm socket. Double-check your owner's manual.
* Drain pan: Large enough to hold at least 6 quarts of oil.
* Funnel: To avoid spills when adding new oil.
* Jack and jack stands (or ramps): Essential for safe access to the drain plug. Never work under a vehicle supported only by a jack.
* Wheel chocks: For added safety.
* Gloves: To keep your hands clean.
* Rags or shop towels: For cleanup.
* Torque wrench (optional but recommended): To tighten the drain plug to the correct specification (check your owner's manual).
2. Prepare the Vehicle:
* Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily. Don't let it get too hot though!
* Secure the vehicle: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels opposite the jacking point.
* Jack up the vehicle: Use the jack to lift the front of the car, placing jack stands securely under the frame near the front wheels before getting under the car.
3. Drain the Old Oil:
* Locate the oil drain plug: It's located on the oil pan, usually towards the bottom of the engine.
* Position the drain pan: Place the drain pan under the drain plug.
* Remove the drain plug: Carefully loosen and remove the drain plug using the appropriate wrench. Be careful, as the oil will be hot.
* Let the oil drain: Allow the oil to drain completely. This can take 15-20 minutes.
4. Replace the Oil Filter:
* Locate the oil filter: It's typically on the side of the engine block.
* Loosen the oil filter: Use the oil filter wrench to loosen and remove the old oil filter. Be prepared for some oil to spill out.
* Lubricate the new oil filter gasket: Lightly lubricate the rubber gasket on the new oil filter with fresh oil.
* Install the new oil filter: Screw the new oil filter on by hand, tightening it according to the manufacturer's instructions (usually about ¾ to 1 full turn after the gasket makes contact).
5. Reinstall the Drain Plug:
* Replace the drain plug: Carefully screw the drain plug back into the oil pan.
* Tighten the drain plug: Use the wrench to tighten the drain plug to the manufacturer's specified torque (check your owner's manual). Overtightening can damage the oil pan. A torque wrench is highly recommended here.
6. Add New Oil:
* Locate the oil fill cap: It's usually located on top of the engine.
* Remove the oil fill cap: Remove the oil fill cap.
* Add new oil: Using the funnel, pour in the correct amount of new oil as specified in your owner's manual.
* Check the oil level: Use the dipstick to check the oil level. Add more oil if necessary, ensuring it's between the minimum and maximum marks on the dipstick.
7. Clean Up and Final Check:
* Lower the vehicle: Carefully lower the vehicle using the jack.
* Dispose of old oil and filter properly: Take the used oil and filter to a recycling center or auto parts store that accepts used oil.
* Start the engine: Run the engine for a few minutes to circulate the new oil.
* Check for leaks: Inspect the area around the drain plug and oil filter for any leaks.
* Recheck the oil level: After running the engine, let it sit for a few minutes, then recheck the oil level and add more if needed.
Important Considerations:
* Consult your owner's manual: This guide provides general instructions. Always refer to your owner's manual for specific information about your 2007 Ford Mustang 4.0L V6.
* Safety first: Always use jack stands when working under a vehicle. Never work under a car supported only by a jack.
* Dispose of used oil properly: Used motor oil is hazardous waste. Dispose of it responsibly.
If you are uncomfortable performing this task yourself, it's always best to take your vehicle to a qualified mechanic.
