🔧 Tucson - Engine Oil & Oil Filter Replacement
On your Tucson, an oil change drains the old engine oil, replaces the oil filter, then refills with the correct oil. Fresh oil protects the engine from wear and helps it run cooler and cleaner.
Difficulty Level: Beginner | Estimated Time: 0.8-1.5 hours
⚠️ Safety & Precautions
- ⚠️ Work on a level surface and support the Tucson with jack stands before going underneath.
- ⚠️ Engine oil can be hot—let the engine cool 15-30 minutes to avoid burns.
- ⚠️ Keep oil off the drive belt and exhaust components.
- ⚠️ Do not get under the Tucson with only a floor jack holding it up.
- ⚠️ Battery disconnect is not required for this service.

🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Engine oil (SAE 5W-20, full synthetic, API SP / ILSAC GF-6) - Qty: 6 quarts
- Oil filter - Qty: 1
- Drain plug gasket/washer - Qty: 1
📋 Before You Begin
- Park on level ground, shift to P, and set the parking brake.
- Chock the rear wheels with wheel chocks.
- Warm the engine 2-3 minutes, then shut it off. Warm oil drains faster.
- Open the hood and remove the oil filler cap by hand to help the crankcase vent while draining.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Raise and support the Tucson
- Use a floor jack to lift the front of the Tucson at the front center jacking point.
- Place jack stands under the reinforced pinch weld points and lower the Tucson onto them.
- Give the vehicle a gentle push to confirm it’s stable before going underneath.
Step 2: Remove the lower splash shield (if equipped)
- Use a 10mm socket and socket wrench to remove the bolts.
- Use a Phillips screwdriver and/or trim clip removal tool to remove any plastic clips.
- Set hardware aside in a small container so nothing gets lost.
Step 3: Drain the engine oil
- Position the drain pan under the oil pan drain plug.
- Use a 17mm socket and socket wrench to loosen the drain plug, then finish removing it by hand.
- Let the oil drain until it becomes a slow drip (usually 5-10 minutes).
- Replace the drain plug gasket/washer with the new one.
- Reinstall the drain plug by hand first (to prevent cross-threading), then tighten with a torque wrench and 17mm socket: Torque to 39-44 Nm (29-32 ft-lbs).
Step 4: Remove and replace the oil filter (choose the type you have)
- Wipe around the filter area with shop rags to keep dirt out.
- Position the drain pan under the filter—oil will spill when you remove it.
Step 4A: If your Tucson has a spin-on metal oil filter
- Use an oil filter wrench to loosen the filter, then spin it off by hand.
- Make sure the old rubber gasket came off with the old filter (it should not stick to the engine).
- Lightly coat the new filter gasket with fresh oil (use a finger).
- Install the new filter by hand until the gasket touches, then tighten 3/4 turn by hand.
Step 4B: If your Tucson has a cartridge filter in a housing (plastic/metal cap)
- Use the oil filter cap socket, 67mm 14-flute (specialty) with a socket wrench to loosen the housing cap. (A cap socket is a cup-shaped wrench that fits over the housing cap.)
- Remove the cap and old filter element, keeping it over the drain pan.
- Replace the housing O-ring(s) if your new filter kit includes them, and lightly oil the O-ring(s) with fresh oil.
- Reinstall the cap and tighten with a torque wrench and the 67mm 14-flute cap socket: Torque to 11-15 Nm (8-11 ft-lbs).
Step 5: Reinstall the splash shield (if removed)
- Position the shield and start all fasteners by hand.
- Use a 10mm socket and socket wrench to snug the bolts, and a Phillips screwdriver for any screws.
Step 6: Refill with fresh oil
- Lower the Tucson from the jack stands using the floor jack.
- Insert a funnel into the oil fill hole and add about 5.0 quarts of SAE 5W-20 oil.
- Reinstall the oil filler cap by hand.
- Wait 2 minutes, then check the dipstick and top off to the upper mark (typical total is around 5.1 quarts with filter).
Step 7: Start the engine and check for leaks
- Start the engine and let it idle for 30-60 seconds.
- Shut the engine off and look underneath for leaks at the drain plug and oil filter.
- Wait 2-3 minutes, then recheck the dipstick and top off if needed.
Step 8: Reset the service reminder (if enabled)
- With the ignition on, use the steering wheel buttons to navigate the cluster menu.
- Follow the path (varies by cluster): User Settings > Service Interval > Reset or Setup > Vehicle > Service Interval > Reset.
✅ After Repair
- Recheck for leaks after your first short drive (5-10 minutes).
- Verify the oil level on the dipstick the next morning on a cold engine and top off if needed.
- Pour the used oil into a sealed container and take it (and the old filter) to an oil-recycling drop-off location.
