What You’ll Need

Step-by-Step Instructions
Step 1: Prepare Your Subaru for an Oil Change
Park on a Level Surface: Make sure your car is on a flat surface and turn off the engine.
Let the Engine Cool: Wait 10-15 minutes to avoid burns from hot oil.
Lift the Vehicle (Optional): If needed, use ramps or a jack and jack stands for better access to the oil drain plug.
Step 2: Drain the Old Engine Oil
Locate the Drain Plug: It's under the engine, typically near the front skid plate.
Position the Drain Pan: Place an oil catch pan underneath the drain plug.
Remove the Drain Plug: Use a 14mm socket wrench to loosen it and let the oil drain completely.
Replace the Drain Plug Washer: Always install a new OEM crush washer for a proper seal.
Reinstall the Drain Plug: Tighten it securely, but avoid over-tightening.
Step 3: Replace the Oil Filter
Locate the Oil Filter: On Subaru Boxer engines, the oil filter is usually on top of the engine or near the bottom.
Remove the Old Filter: Use an oil filter wrench if necessary. Expect some oil to drip out.
Prepare the New OEM Filter:
Apply a thin layer of new oil to the rubber gasket.
This helps with sealing and easy removal later.
Install the New Filter: Hand-tighten until snug; do not overtighten.
Step 4: Refill with Genuine Subaru Engine Oil
Find the Oil Fill Cap: It’s on top of the engine. Remove it.
Pour in the Correct Amount of Oil:
Subaru Impreza, Forester, Outback, Legacy, and Crosstrek (2.5L): ~4.4 quarts
Subaru WRX (2.0L Turbo): ~5.4 quarts
Subaru Ascent (2.4L Turbo): ~5.3 quarts
Use a Funnel: To avoid spills, pour the oil carefully.
Replace the Oil Fill Cap: Ensure it's secure.
Step 5: Check Your Work
Start the Engine: Let it run for 30 seconds to circulate oil.
Check for Leaks: Look underneath the engine for any drips.
Check the Oil Level: Use the dipstick to ensure the oil is at the correct level.
