🔧 Frontier - Engine Oil & Oil Filter Replacement

On your Frontier, an oil change replaces the engine oil and the spin-on oil filter so the engine stays lubricated and clean. This is routine maintenance, and doing it on time helps prevent internal wear and sludge buildup.

Difficulty Level: Beginner | Estimated Time: 45-90 minutes

⚠️ Safety & Precautions

• ⚠️ Let the engine cool 15–30 minutes; oil can burn you.
• ⚠️ Support the truck with jack stands; never rely on a floor jack alone.
• ⚠️ Keep oil off the exhaust and skid plates to avoid smoke/odor.
• ⚠️ Wear nitrile gloves and safety glasses.
• ⚠️ Battery disconnect is not required for this service.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• Warm the engine for 2–3 minutes, then shut it off. Warm oil drains faster.
• Raise the front with a floor jack and set it securely on jack stands.
• Open the hood and remove the oil fill cap by hand (this helps the crankcase vent while draining).
• If equipped, remove the front skid plate to access the drain plug and filter.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the skid plate (if equipped)

• Position your drain pan (8-quart minimum) under the engine area.
• Use a 12mm socket, 3/8" drive ratchet, and 6" socket extension to remove the skid plate bolts.
• Lower the skid plate and set it aside.

Step 2: Drain the old engine oil

• Slide the drain pan (8-quart minimum) under the oil pan drain plug.
• Use a 14mm socket and 3/8" drive ratchet to loosen the drain plug, then finish removing it by hand.
• Let the oil drain until it slows to an occasional drip (usually 5–10 minutes).
• Remove the old crush washer from the drain plug and install the new drain plug crush washer.

Step 3: Reinstall and torque the drain plug

• Wipe the drain hole area with shop rags.
• Thread the drain plug in by hand first to avoid cross-threading.
• Use a torque wrench (10–80 ft-lbs range) with a 14mm socket and Torque to 34 N·m (25 ft-lbs).

Step 4: Remove the oil filter

• Move the drain pan (8-quart minimum)
• Use an oil filter wrench (cap or band style) to break the filter loose, then spin it off by hand.
• Make sure the old rubber gasket came off with the filter (it can stick to the engine). Double-gasket leaks fast.

Step 5: Install the new oil filter

• Put a light film of fresh oil on the new filter’s rubber gasket using a gloved finger (nitrile gloves).
• Spin the new filter on by hand until the gasket contacts the base.
• Tighten by hand an additional 2/3 turn (do not use the filter wrench to tighten).

Step 6: Reinstall the skid plate (if removed)

• Position the skid plate back in place.
• Use a 12mm socket, 3/8" drive ratchet, and 6" socket extension to install and snug the bolts evenly.

Step 7: Refill with new oil

• Insert a funnel into the oil fill hole.
• Pour in about 5.0 quarts of 5W-30 full synthetic first.
• Reinstall the oil fill cap by hand.

Step 8: Start, check for leaks, then set the 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 into the pan.
• Check underneath for leaks at the drain plug and oil filter; use safety glasses.
• Check the dipstick, then add oil in small amounts until it reaches the full mark (your Frontier typically ends up around ~5.1 quarts with filter). Sneak up on “Full.”

✅ After Repair

• Dispose of used oil and the old filter properly at an oil recycling drop-off.
