⚠️ Safety & Precautions

• ⚠️ Work on a level surface so the oil drains correctly and the vehicle stays stable.
• ⚠️ Let the engine cool until it is warm, not hot. Hot oil can burn your skin.
• ⚠️ Use jack stands if lifting the front of the vehicle. Never rely on a floor jack alone.
• ⚠️ Keep oil off the exhaust and belts. Wipe spills right away with shop towels.
• ⚠️ Do not overtighten the drain plug or oil filter. The oil pan threads can be damaged.

📋 Before You Begin

• 🧱 Place wheel chocks behind the rear wheels so the vehicle cannot roll.
• 🌡️ Run the engine for 2-3 minutes if it is cold, then shut it off. Warm oil drains faster.
• 🧰 A torque wrench is a tool that tightens bolts to a measured amount, helping prevent leaks and stripped threads.
• 🛢️ A crush washer is a soft sealing washer on the drain plug. Replace it every oil change.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Secure the Front

• Use the floor jack rated 2-ton minimum at the front center jacking point to raise the front of your Outback if you need more room.
• Place jack stands rated 2-ton minimum under the front side support points.
• Gently lower the vehicle onto the jack stands and lightly shake the vehicle to confirm it is stable.
• Skip lifting if you fit underneath safely.

• Put on nitrile gloves and safety glasses.
• Open the hood.
• Remove the engine oil fill cap by hand. This helps the oil drain smoothly.
• Pull the dipstick up slightly by hand to let air enter the crankcase.

Step 3: Remove the Lower Access Cover if Needed

• Look under the front of the engine for the oil drain plug and filter area.
• If the access panel is in the way, use a flat-blade screwdriver to release the plastic clips.
• Set the clips and panel aside in order so they go back in the same places.

Step 4: Drain the Old Engine Oil

• Place the drain pan 6-quart minimum directly under the engine oil drain plug.
• Use a 17mm socket and 3/8-inch drive ratchet to loosen the drain plug counterclockwise.

• Torque to 41 Nm (30 ft-lbs).

Step 7: Remove the Old Oil Filter

• Use the oil filter wrench 65/67mm 14-flute with the 3/8-inch drive ratchet to turn the filter counterclockwise.
• Unscrew the filter by hand once it is loose.
• Check that the old rubber gasket came off with the filter. A stuck gasket can cause a major leak.

Step 8: Install the New Oil Filter

• Apply a thin film of new 0W-20 full synthetic engine oil to the new oil filter gasket using a gloved finger.
• Thread the new engine oil filter on by hand until the gasket touches the mounting surface.
• Tighten the filter by hand an additional 3/4 turn after gasket contact.
• If using the oil filter wrench 65/67mm 14-flute and 3/8-inch drive torque wrench, Torque to 14 Nm (10 ft-lbs).
• Hand-tight is usually enough for filters.

Step 9: Add New Engine Oil

• Place the oil funnel into the oil fill opening.
• Pour in about 4.8 quarts of 0W-20 full synthetic engine oil.
• Reinstall the oil fill cap by hand.
• Push the dipstick fully back into place by hand.

Step 10: Start and Check for Leaks

• Start the engine and let it idle for 30-60 seconds.
• Use a flashlight if available to inspect around the drain plug and oil filter.
• If you see dripping oil, shut the engine off immediately and recheck the filter and drain plug with the correct tool.
• Shut the engine off and wait 5 minutes so oil can drain back into the oil pan.

Step 11: Set the Final Oil Level

• Pull the dipstick out by hand and wipe it clean with shop towels.
• Reinsert it fully, then pull it out again to read the level.
• Add small amounts through the oil funnel until the level is near the full mark.
• Total refill with filter is about 5.1 quarts, but always finish by dipstick reading.
• Reinstall the oil fill cap and dipstick by hand.

Step 12: Reinstall the Access Cover and Lower the Vehicle

• If removed, reinstall the lower access cover using the flat-blade screwdriver to secure the plastic clips.
• Use the floor jack rated 2-ton minimum to raise the vehicle slightly off the jack stands.
• Remove the jack stands rated 2-ton minimum.
• Lower the vehicle slowly with the floor jack rated 2-ton minimum.
• Remove the wheel chocks.

Step 13: Reset the Maintenance Reminder
