⚠️ Safety & Precautions

• ⚠️ Work on a cool or warm engine, not a hot one. Hot oil can burn skin.
• ⚠️ Park on level ground so the oil drains correctly and the oil level reads accurately.
• ⚠️ Always support your Outback with jack stands if you raise it. Never rely on a jack alone.
• ⚠️ Wear safety glasses and nitrile gloves to protect your eyes and skin from used oil.
• ⚠️ Used engine oil is hazardous. Collect it in a sealed container and recycle it properly.
• ⚠️ 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.
• 🌡️ Let the engine run for 2-3 minutes, then shut it off. Warm oil drains faster.
• 📘 A torque wrench is a tool that tightens bolts to an exact tightness, measured in ft-lbs or Nm.
• 🧰 A crush washer is a soft sealing washer that deforms when tightened and should be replaced each oil change.
• ♻️ Have a clean container ready so you can take the used oil 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 the jack stands rated 2-ton minimum under the front side support points.
• Lower the vehicle gently onto the jack stands.
• Use wheel chocks behind the rear wheels to prevent movement.
• Give the car a gentle shake.

Step 2: Open the Oil Fill Cap

• Put on safety glasses and nitrile gloves.
• Open the hood by pulling the hood release inside the cabin.
• Remove the engine oil fill cap by hand from the top of the engine.
• Pull the dipstick up slightly by hand. This helps air enter while the old oil drains.

Step 3: Position the Drain Pan

• Slide the drain pan 8-quart minimum under the engine oil drain plug.
• The drain plug is on the bottom of the engine oil pan.
• Use shop towels nearby for spills.

Step 4: Remove the Oil Drain Plug

• Use a 17mm socket and 3/8-inch drive ratchet to loosen the oil drain plug counterclockwise.
• Finish removing the plug carefully by hand while keeping pressure inward until the last thread releases.
• Let the oil drain into the drain pan 8-quart minimum until it slows to a drip.
• Keep your hand out of the oil stream.

Step 5: Replace the Drain Plug Washer

• Use shop towels to wipe the drain plug clean.
• Remove the old crush washer by hand from the drain plug.
• Install the new oil drain plug crush washer onto the drain plug by hand.
• Wipe the oil pan sealing surface with shop towels.

Step 6: Reinstall the Drain Plug

• Thread the drain plug into the oil pan by hand first. This prevents cross-threading, which means damaging the threads by starting the bolt crooked.
• Use the 17mm socket and 3/8-inch drive ratchet to snug the plug.
• Use the 17mm socket and 3/8-inch drive torque wrench to tighten the drain plug to Torque to 44 Nm (32.5 ft-lbs).

Step 7: Remove the Old Oil Filter

• Move the drain pan 8-quart minimum under the oil filter area.
• Use the oil filter wrench 68mm 14-flute with the 3/8-inch drive ratchet to loosen the oil filter counterclockwise.
• Remove the filter by hand once loose.
• Make sure the old rubber gasket came off with the filter. A gasket is the rubber sealing ring on the filter.
• Use shop towels to clean the filter mounting surface.

Step 8: Install the New Oil Filter

• Lightly coat the new oil filter gasket with fresh engine oil 5W-30 synthetic using a gloved finger.
• Thread the new engine oil filter on by hand until the gasket contacts the mounting surface.
• Tighten the filter by hand an additional 3/4 turn.
• If using the oil filter wrench 68mm 14-flute and 3/8-inch drive torque wrench, tighten the filter to Torque to 14 Nm (10 ft-lbs).
• Do not overtighten the filter.

Step 9: Add New Engine Oil

• Place the funnel with narrow spout into the oil fill opening.
• Pour in about 6.5 quarts of engine oil 5W-30 synthetic.
• Remove the funnel with narrow spout and install the oil fill cap by hand.
• Push the dipstick fully back into place by hand.

Step 10: Start the Engine and Check for Leaks

• Start the engine and let it idle for 30-60 seconds.
• Shut the engine off.
• Use safety glasses and inspect underneath for leaks at the drain plug and oil filter.
• Use shop towels to wipe any oil residue so new leaks are easy to spot.

Step 11: 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 your Outback slowly to level ground with the floor jack rated 2-ton minimum.
• Remove the wheel chocks.

Step 12: Set the Final Oil Level

• Wait 5 minutes so the oil can drain back into the oil pan.
• Pull the dipstick by hand and wipe it clean with shop towels.
• Reinsert the dipstick fully, then pull it out again to read the level.
• Add engine oil 5W-30 synthetic through the funnel with narrow spout in small amounts until the oil level reaches the full mark.
• Do not overfill. The typical refill amount with filter is about 6.9 quarts.

Step 13: Reset the Maintenance Reminder

• Use the steering wheel controls or instrument panel controls to access the vehicle information display.
• Select Maintenance > Engine Oil > Reset if your display has the maintenance menu.
• If the maintenance menu is not enabled, record the mileage and reset your reminder manually using your preferred service log.
