🔧 QX80 - Engine Oil & Oil Filter Change

You’ll drain the old engine oil, replace the oil filter, then refill with the correct full-synthetic oil. Fresh oil protects your engine from wear and helps it run cooler and cleaner.

Difficulty Level: Beginner | Estimated Time: 1.0-2.0 hours

Assumption: Specs can vary by filter and production changes—verify final oil level on the dipstick after filling.

⚠️ Safety & Precautions

• ⚠️ Work on level ground and support the truck on jack stands, never just a jack.
• ⚠️ Engine oil can be hot—let it cool 15–30 minutes to avoid burns.
• ⚠️ Keep oil off belts, rubber hoses, and your driveway (use a drain pan).
• ⚠️ No battery disconnect is required for this service.

📋 Before You Begin

• Park on a level surface, shift to Park, and set the parking brake.
• Chock the rear wheels using wheel chocks.
• Warm the engine for 2–3 minutes, then shut it off so the oil drains faster but isn’t scorching hot.
• If you lift the front, raise it using a floor jack (rated 3-ton minimum) and support it with jack stands (rated 3-ton minimum).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the front under-cover (if equipped)

• Put on safety glasses and nitrile gloves.
• Position the drain pan (10-quart minimum) under the engine area.
• Use a 10mm socket with a 3/8" drive ratchet to remove under-cover bolts.
• Use a trim clip remover to pop out plastic clips (a trim clip remover is a forked tool that lifts clips without breaking them).

Step 2: Drain the old engine oil

• Locate the oil drain plug on the bottom of the oil pan.
• Use a 14mm socket with a 3/8" drive ratchet to loosen the drain plug.
• Finish unthreading by hand and quickly pull the plug away so oil flows into the drain pan (10-quart minimum).
• Let it drain until it slows to an occasional drip (typically 10–15 minutes).

Step 3: Replace the drain plug washer and reinstall the plug

• Remove the old washer from the drain plug and install the new drain plug crush washer.
• Thread the drain plug in by hand first to avoid cross-threading.
• Use a torque wrench (10–80 ft-lb range) with a 14mm socket to tighten the drain plug: Torque to 34 Nm (25 ft-lbs).
• Tip: If it doesn’t thread easily, stop and realign.

Step 4: Remove the oil filter

• Move the drain pan (10-quart minimum) under the oil filter area (some oil will spill).
• Use an oil filter wrench (cap or band style) to loosen the filter (an oil filter wrench grips the filter so you can turn it).
• Unscrew the filter by hand and keep it upright as you remove it.
• Wipe the filter mounting surface using shop towels.
• Make sure the old rubber gasket came off with the filter.

Step 5: Install the new oil filter

• Lightly coat the new filter’s rubber gasket with fresh engine oil (0W-20 full synthetic).
• Screw the new filter on by hand until the gasket touches the base.
• Tighten by hand an additional 2/3 turn, or use a torque wrench (10–80 ft-lb range) with the correct oil filter wrench (cap or band style): Torque to 17 Nm (13 ft-lbs).
• Tip: Hand-tight plus 2/3 turn is usually perfect.

Step 6: Reinstall the under-cover

• Reposition the under-cover.
• Install clips using the trim clip remover (press clips in straight).
• Tighten bolts using a 10mm socket with a 3/8" drive ratchet.

Step 7: Refill with new engine oil

• Lower the truck off the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).
• Remove the oil fill cap on top of the engine.
• Place a funnel in the fill hole.
• Pour in 6.5 quarts of engine oil (0W-20 full synthetic) first.
• Reinstall the oil fill cap.

Step 8: Start, check for leaks, and set the final oil level

• Start the engine and let it idle for 30–60 seconds.
• Shut the engine off and wait 5 minutes for oil to drain back to the pan.
• Check underneath for leaks at the drain plug and oil filter using safety glasses.
• Check the dipstick level and add oil in small amounts (0.25 qt at a time) using the funnel until it reaches the full mark (most QX80 setups land around ~6.9 qt total with filter).
• Wipe spills using shop towels.

Step 9: Reset the oil/oil filter maintenance reminder

• Turn ignition ON (engine off).
• Using the steering wheel buttons, navigate the driver display menus: Settings > Maintenance > Oil and Filter > Reset.
• If your display wording differs, look for: Settings > Maintenance, then reset “Oil” and “Filter.”
