🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and loosen the fill cap

• Remove the oil fill cap by hand (top of the engine) and set it aside.
• Pull the dipstick out slightly by hand (1–2 inches). This helps the crankcase vent while draining.

Step 2: Position the drain pan

• Slide an oil drain pan (10-quart minimum) under the oil pan drain plug.
• Place shop towels nearby for cleanup.

Step 3: Remove the drain plug and drain the oil

• Use a 15mm socket with a 3/8" drive ratchet to loosen and remove the drain plug.
• Keep inward pressure on the plug as you unthread it, then pull it away quickly so oil flows into the pan.
• Let it drain until it slows to an occasional drip (usually 5–10 minutes).

Step 4: Reinstall and torque the drain plug

• Wipe the drain plug and the sealing surface with shop towels.
• If your plug uses a replaceable gasket/washer, install the new one by hand.
• Thread the drain plug in by hand first (prevents cross-threading).
• Use a 3/8" drive torque wrench with a 15mm socket: Torque to 25 Nm (18 ft-lbs).

Step 5: Remove the oil filter

• Move the oil drain pan under the oil filter area (it will spill).
• Use an oil filter wrench (cap or band style) to loosen the oil filter, then spin it off by hand.
• Make sure the old rubber gasket comes off with the old filter (it can stick to the engine). Double-gasket causes big leaks.

Step 6: Install the new oil filter

• Wipe the filter mounting surface clean using shop towels.
• Put a thin film of fresh oil on the new filter’s rubber gasket (use a gloved finger with nitrile gloves).
• Spin the new filter on by hand until the gasket contacts the engine, then tighten 3/4 turn more by hand.
• If you can’t tighten by hand due to space, use the oil filter wrench only lightly (do not crush the filter).

Step 7: Refill with new oil

• Insert a funnel into the oil fill hole.
• Pour in 7.5 quarts first (SAE 5W-30 full synthetic, dexos1 approved).
• Reinstall the oil fill cap by hand.

Step 8: Start, check for leaks, then top off

• Start the engine and let it idle for 30–60 seconds.
• Look underneath for leaks at the drain plug and oil filter (use safety glasses).
• Shut the engine off and wait 5 minutes for oil to settle.
• Check the dipstick and add oil as needed to reach the “full” mark (typically ends up around 8 quarts total with filter).

Step 9: Reset the Oil Life Monitor

• Turn ignition to ON (engine off).
• Use the steering wheel buttons to navigate the Driver Information Center: Menu > Oil Life.
• Press and hold SET/CLR until it resets to 100%.

✅ After Repair

• Verify the oil level one more time on level ground after the engine has been off 5 minutes.
• Pour used oil into a sealed container and take it (and the old filter) to an oil recycling drop-off/parts store.
