🔧 Ioniq - Engine Oil & Oil Filter Change

On your Ioniq, the engine oil lubricates and cools the gas engine, and the oil filter traps dirt/metal particles. Replacing both on schedule helps prevent engine wear and keeps the hybrid system running efficiently.

Difficulty Level: Beginner | Estimated Time: 0.8-1.5 hours

⚠️ Safety & Precautions

• ⚠️ Make sure the car is fully OFF (not in READY) before going underneath.
• ⚠️ Use jack stands—never rely on a floor jack alone.
• ⚠️ Engine oil can be hot; let the engine cool 15-30 minutes if needed.
• ⚠️ On hybrids, avoid touching any orange high-voltage cables/components under the car.
• ⚠️ Keep the key fob at least 10+ feet away so the car can’t wake up.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front of the car

• Use a floor jack (rated 2-ton minimum) to lift the front at the correct front center jack point.
• Place jack stands (rated 2-ton minimum) at the left and right front support points, then lower the car onto the stands.
• Give the car a gentle shake to confirm it’s stable before you go underneath.

Step 2: Remove the lower engine cover (undertray)

• Use a Phillips screwdriver and flat trim clip tool to remove the screws/clips holding the undertray.
• Set the clips aside so they don’t get lost.
• Trim clip tool prevents breaking fasteners.

Step 3: Drain the engine oil

• Place your drain pan (at least 6-quart) under the oil pan drain plug.
• Use a 17mm socket with a 3/8" drive ratchet to loosen and remove the drain plug.
• Let the oil drain until it slows to an occasional drip (usually 5-10 minutes).
• Replace the drain plug gasket/washer with the new one.

Step 4: Reinstall and torque the drain plug

• Thread the drain plug in by hand first (to avoid cross-threading).
• Use a torque wrench (10-80 Nm range) with a 17mm socket to tighten the drain plug.
• Torque to 39 Nm (29 ft-lbs)
• If it won’t hand-thread, stop and realign.

Step 5: Remove the oil filter

• Reposition the drain pan (at least 6-quart) under the oil filter area (some oil will spill).
• Use an oil filter wrench (cap or band type) to loosen the filter, then spin it off by hand.
• Make sure the old rubber gasket comes off with the old filter (not stuck to the engine).

Step 6: Install the new oil filter

• Wipe the engine’s filter sealing surface clean with shop rags.
• Lightly oil the new filter’s rubber gasket using a dab of fresh oil on a gloved finger.
• Spin the new filter on by hand until the gasket touches, then tighten.
• If you can fit your torque wrench (10-80 Nm range) with the correct adapter for your oil filter wrench (cap type): Torque to 12 Nm (9 ft-lbs)
• If you can’t torque it: tighten by hand about 3/4 turn after gasket contact.

Step 7: Reinstall the undertray

• Reposition the undertray and start all screws/clips by hand.
• Use a Phillips screwdriver and flat trim clip tool to secure all fasteners snugly.

Step 8: Add new engine oil

• Lower the car off the jack stands using the floor jack (rated 2-ton minimum).
• Open the hood and remove the oil fill cap.
• Use a funnel and add 0W-20 full synthetic, starting with about 3.5 quarts.
• Reinstall the oil fill cap.

Step 9: Start, check for leaks, then set the final oil level

• Start the engine and let it run for 30-60 seconds, then shut it off.
• Look underneath for leaks at the drain plug and oil filter.
• Wait 5 minutes, then check the dipstick and top off as needed to reach the full mark.
• Don’t overfill—add in small amounts and recheck.
