🔧 Silverado 1500 - Engine Oil and Filter Change
This is a very manageable first DIY service. You’ll drain the old oil, replace the spin-on filter, refill the engine, and reset the oil-life monitor.
Difficulty Level: Beginner | Estimated Time: 45-75 minutes
Assumption: These specifications apply to the stock U.S.-market 6.2L gasoline engine.
⚠️ Safety & Precautions
- ⚠️ Work on level, solid ground with the transmission in Park and the parking brake engaged.
- 🛑 Never crawl under your Silverado while it’s supported only by a floor jack.
- 🌡️ Warm oil drains better, but hot oil and exhaust parts can cause serious burns.
- 🧤 Wear gloves and safety glasses because used engine oil is irritating.
- 🔋 Battery disconnection isn’t required.
- ♻️ Collect every drop and take the used oil and filter to a recycling facility.
🔧 Required Tools
You'll need the following tools for this repair:
- 15mm six-point socket
- 3/8-inch-drive ratchet
- 3/8-inch-drive torque wrench rated 10-80 ft-lbs
- Oil filter wrench sized for 3-inch filters
- Oil drain pan rated 12-quart minimum
- Long-neck engine oil funnel
- Floor jack rated 3-ton minimum
- Jack stands rated 3-ton minimum
- Wheel chocks
- Mechanic gloves
- Safety glasses
- Shop towels
An oil-filter wrench grips a stubborn filter for removal. A torque wrench tightens the drain plug to a measured specification.
🔩 Required Parts
HowToo sells all the parts you need for this repair:
- SAE 0W-20 full-synthetic engine oil meeting GM dexos1 specifications - Qty: 8 quarts
- Wix WL10255 premium spin-on engine oil filter - Qty: 1
- Oil drain plug sealing washer - Qty: 1 if damaged or flattened
I’d use the Wix here. It has a silicone anti-drainback valve and is built around the manufacturer’s normal service interval. Cheap oil changes get expensive the moment they start dripping.
📋 Before You Begin
- 📍 Park your Silverado on level pavement and apply the parking brake.
- 🛞 Place wheel chocks firmly behind both rear tires.
- 🌡️ Run the engine for about three minutes, then shut it off and wait five minutes.
- ⬆️ If additional clearance is needed, lift the front using the frame-approved lifting point and support both sides with jack stands.
- 🧰 Position the drain pan before loosening either the plug or filter.
- 📏 Confirm the new oil container says SAE 0W-20 and carries the current dexos1 approval.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the oil fill point
- Open the hood and locate the oil filler cap on top of the engine.
- Remove the cap by hand and place it somewhere clean.
- Pull the dipstick slightly upward to let air enter while the oil drains.
- Keep dirt away from the open filler neck.
Step 2: Position the drain pan
- Put on the mechanic gloves and safety glasses.
- Slide the 12-quart drain pan beneath the engine oil-pan drain plug.
- Place the pan slightly behind the plug because the oil initially exits with some force.
Step 3: Drain the old engine oil
- Use the 15mm six-point socket and 3/8-inch-drive ratchet to loosen the drain plug counterclockwise.
- Finish removing the plug carefully by hand while keeping inward pressure on it.
- Pull the plug away quickly and allow the oil to drain for at least 10 minutes.
- Inspect the plug threads and sealing washer. Replace the washer if it’s cut, flattened, or distorted.
Step 4: Reinstall the drain plug
- Clean the drain-plug threads and sealing surface with shop towels.
- Start the plug by hand for several full turns. It should thread in easily.
- Use the 15mm socket and torque wrench to tighten the plug to 25 Nm (18 ft-lbs).
- Never use an impact wrench on the drain plug.
Step 5: Remove the old oil filter
- Move the drain pan directly below the oil filter.
- Use the oil filter wrench to turn the filter counterclockwise until it loosens.
- Unscrew the filter by hand and keep it upright as you lower it.
- Check the engine’s filter mounting surface. Make sure the old rubber gasket didn’t stick to it.
- A stuck old gasket would create a double gasket and a major leak.
Step 6: Install the new oil filter
- Use a clean finger to spread fresh 0W-20 oil around the new filter’s rubber gasket.
- Thread the new filter clockwise onto the mounting stud by hand.
- Once the gasket touches the mounting surface, tighten the filter approximately three-quarters of one additional turn by hand.
- Don’t use the filter wrench for final tightening unless the filter manufacturer specifically instructs it.
- Hand tight is right for a spin-on filter.
Step 7: Refill the engine
- Insert the long-neck funnel into the oil filler opening.
- Pour in 7.5 quarts of SAE 0W-20 full-synthetic oil first.
- Wait one minute, remove the funnel, and install the filler cap by hand.
- Seat the dipstick fully.
Step 8: Build oil pressure and inspect
- Confirm that no tools remain beneath the truck or inside the engine compartment.
- Start the engine and let it idle for 30-60 seconds.
- Verify that the oil-pressure warning light goes out promptly.
- Use a flashlight to inspect the drain plug and oil filter for fresh leakage.
- Shut the engine off immediately if the warning light stays on or oil leaks rapidly.
Step 9: Set the final oil level
- Shut the engine off and wait at least five minutes on level ground.
- Remove the dipstick, wipe it clean with a shop towel, reinstall it fully, and remove it again.
- Add oil in small amounts until the level reaches the upper crosshatched mark without going above it.
- The expected total capacity with a new filter is approximately 8 quarts.
- Reinstall the dipstick and tighten the filler cap by hand.
Step 10: Reset the oil-life monitor
- Turn the ignition on without starting the engine.
- Use the steering-wheel controls to open Driver Information Center > Info > Oil Life.
- Press and hold the check-mark button until the display resets to 100%.
- If prompted, select Yes using the steering-wheel controls.
- Start the engine and confirm the oil-life display remains at 100%.
✅ After Repair
- ✅ Recheck the oil level after the engine has been off for five minutes.
- 🔍 Inspect the drain plug and filter again after your first short drive.
- 📏 Keep the oil level between the dipstick marks. Don’t overfill it.
- ♻️ Pour the used oil into a sealed container and recycle it with the old filter.
- 🧾 Record the date, mileage, oil viscosity, and filter used.
