How to Change the Oil on Your 2018 Chevy Silverado 5.3L V8: Step-by-Step Guide
Performing your own oil maintenance yields immense personal satisfaction while saving you hundreds of dollars compared to inflated dealership maintenance invoices.
Gather the following required tools before beginning the process:
- 15mm socket and ratchet wrench
- Oil filter strap wrench
- 10-quart capacity drain pan
- Clean shop rags and funnel
- 8.0 quarts of 0W-20 Dexos1 approved full synthetic oil
- ACDelco PF63E engine oil filter
- Safety glasses and nitrile gloves
Completing these step-by-step DIY oil change steps 2018 chevy takes approximately 30 to 45 minutes in your garage or driveway.
Step 1: Safely Prepare and Elevate the Truck
Park your Silverado on a flat level concrete surface and set the emergency parking brake firmly.
Allow the engine to idle for three minutes so the motor oil warms up slightly without becoming burning hot.
If extra ground clearance is needed, raise the front end using a rated hydraulic floor jack and secure the truck on heavy-duty jack stands.
Step 2: Drain the Used Crankcase Oil
Position your drain pan beneath the oil pan drain plug located on the lower driver side of the engine sump.
Use a 15mm socket to loosen the drain plug counterclockwise, then carefully remove it by hand to prevent dropping it into the hot oil.
Allow the dark used fluid to drain completely until it slows down to a very thin trickle.
Inspect the rubber O-ring seal on the drain plug, wipe the threads clean, re-thread it by hand, and torque it to 18 lb-ft (25 Nm).
Step 3: Replace the Engine Oil Filter
Move the drain pan directly underneath the oil filter housing located near the front differential area.
Loosen the filter counterclockwise using your oil filter wrench and allow excess oil to empty into the collection pan.
Clean the mounting flange on the engine block with a shop rag and confirm the old rubber gasket came off with the used filter.
Apply a thin coating of fresh 0W-20 motor oil onto the rubber seal of the new filter before spinning it on by hand until hand-tight, plus three-quarters of a turn.
Step 4: Refill with Fresh 0W-20 Synthetic Oil
Remove the oil fill cap located on the passenger side valve cover and place a clean funnel into the neck.
Pour in exactly 8.0 quarts of fresh full synthetic 0W-20 motor oil into the engine.
Reinstall the oil filler cap securely, start the engine, and let it idle for two minutes while checking underneath for any active leaks.
Shut off the engine, wait five minutes for fluid to settle, pull the dipstick, wipe it clean, reinsert it, and confirm the oil level sits directly in the crosshatched operating zone.
Step 5: Reset the Oil Life Percentage System
Turn the ignition key to the ON position without starting the engine (or hold the Start button for 5 seconds without pressing the brake pedal).
Use the steering wheel control pad to navigate through the Driver Information Center (DIC) screen to the Oil Life menu.
Press and hold the Select button until the display prompts you to confirm, then select Yes to reset oil life percentage driver screen back to 100 percent.

Active Fuel Management (AFM) and Engine Oil Health Mechanics
The 5.3L V8 EcoTec3 engine utilizes Active Fuel Management (AFM) to deactivate four of the eight cylinders under light load conditions to enhance fuel economy.
This cylinder deactivation system relies on oil pressure solenoids to collapse specific hydraulic valve lifters smoothly.
When dirty oil or incorrect fluid weights are used, sludge builds up inside the fine oil galleries feeding the VLOM (Valve Lifter Oil Manifold).
Maintaining the proper 2018 chevy silverado 1500 oil type ensures constant hydraulic pressure to prevent infamous lifter tick or stuck lifter failures.
Mechanics across major Silverado forums report that disciplined 5,000-mile oil changes dramatically decrease AFM system hardware wear over time.
Understanding Oil Filter Engineering for the 5.3L EcoTec3 V8
Choosing an inferior oil filter can starve your engine of vital oil pressure during high RPM operation.
General Motors recommends using ACDelco filters specifically designed with high bypass valve pressure ratings.
Refer to these recommended oil filter part numbers 2018 chevy when buying your maintenance supplies:
- Standard OEM Replacement: ACDelco PF63E (GM Part #19330000)
- Gold/Professional High-Efficiency: ACDelco UPF63R
- Premium Aftermarket Alternatives: Mobil 1 M1-212A or WIX 57045
Ensure the filter you select features a heavy-duty anti-drainback valve to prevent dry startup noise.
Practical Maintenance Schedules and Cost-Saving Measures
Although the Driver Information Center algorithm calculates remaining oil life based on engine revolutions and ambient operating temperature, relying solely on extreme intervals can be risky.
Professional ASE Certified Mechanics recommend changing full synthetic oil every 5,000 to 7,500 miles under normal driving patterns.
If you regularly tow heavy trailers or commute in harsh dust and stop-and-go city traffic, reduce your change interval to 4,000 miles.
Taking a DIY approach to oil maintenance saves between $70 and $110 per service compared to dealer pricing.
Checking your dipstick level bi-weekly is a smart habit because modern direct-injection V8 engines naturally consume up to one quart of oil every 3,000 miles under heavy loads.
Overcoming Common DIY Oil Change Mistakes
Avoiding simple DIY oversights will save you from devastating repair costs down the road.
One frequent mistake is failing to check if the old rubber oil filter gasket detached from the engine block housing.
If a new filter is installed over an old stuck gasket, double-gasketing occurs, causing massive fluid leaks as soon as oil pressure builds.
Another common error is over-tightening the oil pan drain plug, which strips out aluminum threads and leads to expensive oil pan replacements.
Always torque the drain bolt to the specified 18 lb-ft and double-check your total fluid level on the dipstick before driving off.
