2010-2020 Ford 3.5L EcoBoost Engines: Important Tips For a Proper Oil Change!

Introduction

This tutorial will guide you through the process of changing the oil in a Ford 3.5L EcoBoost engine, which is used in various models from 2010 to 2020. Proper oil changes are crucial for maintaining engine health, especially for turbocharged engines like the EcoBoost. By following these steps, you'll ensure your engine runs smoothly and efficiently.

Step 1: Gather Tools and Parts

Before starting, make sure you have the following tools and parts ready:

• Motorcraft Oil Filter (FL 500 S): A reliable filter suitable for this engine.
• 5W-30 Engine Oil: Use high-quality semi-synthetic or full synthetic oil that meets the API SN+ specification.
• Oil Filter Wrench: For easy removal of the old oil filter.
• 15mm Socket or Wrench: For loosening the oil drain plug.
• Tall Oil Funnel: To avoid spills while filling new oil.
• Rags or Paper Towels: For cleaning and wiping any spills.

Step 2: Prepare the Vehicle

1. Heat the Engine: Take your vehicle for a short drive to warm up the engine oil. Warm oil flows out more easily.
2. Park on Level Surface: Once heated, park the vehicle on a flat surface, set the parking brake, and turn off the engine.
3. Ventilation: Open the oil fill cap and dipstick to allow air to flow and facilitate drainage.

Step 3: Drain the Old Oil

1. Remove Underbody Shield: Depending on your model, remove any necessary underbody shields or air ducts to access the oil drain plug. Use a turn-lock fastener or unscrew as required.
2. Locate the Drain Plug: The plug is typically a 15mm bolt located at the bottom of the oil pan.
3. Drain the Oil: Place an oil pan under the drain plug and loosen it with your wrench. Allow the oil to drain completely. This may take some time.

Step 4: Replace the Oil Filter

1. Remove the Old Filter: Use the oil filter wrench to loosen and remove the old oil filter. Expect some oil to spill, so have rags ready.
2. Inspect the Filter Housing: Clean the sealing surface where the oil filter attaches. Ensure the old filter's rubber gasket is not stuck.
3. Prepare the New Filter: Apply a thin layer of new oil to the gasket of the new filter for a proper seal.
4. Install the New Filter: Spin the new filter onto the housing by hand until snug, then tighten slightly more without using a wrench.

Step 5: Reinstall the Drain Plug

1. Clean the Drain Plug: Wipe clean the area around the drain plug and inspect for damage.
2. Reinstall the Plug: Spin the drain plug back in by hand, then tighten it gently with your wrench. Avoid over-torquing to prevent damaging the oil pan.

Step 6: Fill with New Oil

1. Replace Underbody Shield: Reinstall any shields or ducts you removed earlier.
2. Add New Oil: Using the tall funnel, pour approximately 6 quarts of the new 5W-30 oil into the engine.
3. Check Level: After filling, replace the oil fill cap and start the engine. Allow it to run for about 5-10 seconds, then turn it off and check the oil level with the dipstick.

Conclusion

Changing the oil in your Ford 3.5L EcoBoost engine is a straightforward process if you follow these steps. Remember to change the oil every 5,000 miles to maintain engine performance. Regular oil changes are essential for the longevity of turbocharged engines, as they operate under higher stress. Always consult your vehicle's manual for specific recommendations related to your model. Happy driving!
