🔧 Outback - Engine Oil & Oil Filter Replacement
This repair drains the old engine oil, replaces the oil filter, and refills your Outback with fresh oil. Clean oil protects the 3.6L flat-six engine from wear, heat, and sludge buildup.
Difficulty Level: Beginner | Estimated Time: 30-60 minutes
⚠️ Safety & Precautions
- ⚠️ Work on a level surface so the oil drains correctly and the vehicle stays stable.
- ⚠️ Let the engine cool for 10-15 minutes if it is hot; warm oil drains well, but hot oil can burn skin.
- ⚠️ Use jack stands if raising the vehicle. Never rely on a floor jack alone.
- ⚠️ Keep oil off the exhaust and underbody. Wipe spills before starting the engine.
- ⚠️ Battery disconnect is not required for this oil change.

📋 Before You Begin
- 🅿️ Park your Outback on level ground and set the parking brake.
- 🧱 Place wheel chocks behind the rear wheels if lifting the front.
- 🔥 Run the engine for 2-3 minutes if cold, then shut it off. Warm oil flows out faster.
- 🧰 A torque wrench tightens bolts to an exact tightness so they are not too loose or too tight.
- ♻️ Have a sealed container ready for used oil. Take used oil and the old filter to a recycling center or parts store.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Raise and Secure the Front
- Use the floor jack rated 2-ton minimum to lift the front of your Outback at the front center jacking point.
- Place jack stands rated 2-ton minimum under the proper front support points.
- Use wheel chocks behind the rear wheels.
- Gently lower the vehicle onto the jack stands and give the vehicle a light shake to confirm it is stable.
- Never crawl under a jack-only vehicle.
Step 2: Remove the Lower Access Cover if Needed
- Put on safety glasses and nitrile gloves.
- Use a flat-head screwdriver to remove the plastic push clips from the oil drain access area if the cover blocks the drain plug.
- Set the clips aside where they will not get lost.
- A push clip is a reusable plastic fastener that holds splash shields and covers in place.
Step 3: Remove the Oil Fill Cap and Dipstick
- Open the hood.
- Remove the engine oil fill cap by hand.
- Pull the dipstick up slightly by hand.
- This lets air enter the engine so the old oil drains more smoothly.
Step 4: Drain the Old Engine Oil
- Place the drain pan 8-quart minimum under the oil drain plug.
- Use a 17mm socket and 3/8-inch drive ratchet to loosen the drain plug counterclockwise.
- Finish removing the plug by hand while keeping pressure against it until the threads release.
- Let the oil drain until it slows to a drip.
- Remove the old crush washer from the drain plug.
- A crush washer is a soft sealing washer that flattens slightly when tightened and should be replaced each oil change.
Step 5: Reinstall the Drain Plug
- Wipe the drain plug and oil pan sealing area with clean shop towels.
- Install the new oil drain plug crush washer on the drain plug by hand.
- Thread the drain plug into the oil pan by hand first to avoid cross-threading.
- Use a torque wrench 10-50 ft-lbs with the 17mm socket to tighten the drain plug.
- Torque to 41 Nm (30 ft-lbs)
- Start bolts by hand first.
Step 6: Remove the Old Oil Filter
- Move the drain pan 8-quart minimum under the oil filter area because more oil may drip out.
- Use the oil filter wrench 65/67mm 14-flute with the 3/8-inch drive ratchet to loosen the oil filter counterclockwise.
- Spin the filter off by hand once it is loose.
- Check that the old rubber gasket came off with the filter.
- The gasket is the black rubber sealing ring on the filter. If it sticks to the engine, remove it by hand.
Step 7: Install the New Oil Filter
- Dip a gloved finger into fresh engine oil 5W-30 synthetic and lightly coat the new filter gasket.
- Thread the new engine oil filter on by hand until the gasket contacts the mounting surface.
- Tighten the oil filter by hand an additional 3/4 turn, or use the oil filter wrench 65/67mm 14-flute and torque wrench 10-50 ft-lbs if the filter has a torque spec printed on it.
- Torque to 14 Nm (10 ft-lbs)
- Do not overtighten the filter.
Step 8: Reinstall the Lower Access Cover
- Use your hands to position the lower access cover back into place.
- Use the flat-head screwdriver to help reinstall the plastic push clips if needed.
- Make sure the cover is secure and not hanging down.
Step 9: Lower the Vehicle
- Use the floor jack rated 2-ton minimum to lift the front slightly off the jack stands.
- Remove the jack stands rated 2-ton minimum.
- Lower the vehicle slowly to the ground with the floor jack rated 2-ton minimum.
Step 10: Add Fresh Engine Oil
- Place the funnel into the oil fill opening.
- Pour in about 6 quarts of engine oil 5W-30 synthetic.
- Wait 1 minute, then check the dipstick by wiping it with clean shop towels, reinserting it fully, and pulling it out again.
- Add oil slowly until the level is near the full mark.
- The total refill is about 6.9 quarts with filter, but always finish by dipstick level.
- Reinstall the oil fill cap by hand.
Step 11: Start and Leak Check
- Start the engine and let it idle for 30-60 seconds.
- Turn the engine off and wait 5 minutes.
- Use safety glasses, nitrile gloves, and clean shop towels to inspect around the drain plug and oil filter for leaks.
- Check the dipstick again and top off with engine oil 5W-30 synthetic if needed.
Step 12: Reset the Maintenance Reminder
- Turn the ignition to ON without starting the engine.
- Use the steering wheel controls to open the center information display settings.
- Select Pull and hold i/SET switch > Maintenance > Engine Oil > Reset.
- Set the next reminder mileage and date if prompted.
- If your display layout differs, use Home > Settings > Maintenance > Engine Oil > Reset on the infotainment screen.
✅ After Repair
- ✅ Confirm the oil level is at or just below the full mark after the engine has been off for 5 minutes.
- ✅ Check under your Outback after the first drive for any oil drips.
- ✅ Recheck the dipstick the next morning on level ground.
- ✅ Properly recycle the used oil and old oil filter.
- ✅ Record the mileage and date of the oil change.
