What you need to do before you start

A Chevy Silverado oil change follows the same basic steps as any truck, but the location of the drain plug and filter varies by engine size and year. Before you get under the truck, you need to know which engine you have — the oil capacity and filter type differ between the 5.3L V8, 6.2L V8, and diesel engines, and between model years. Your owner's manual lists both, or you can find them on the door jamb label or by looking up your VIN on the Chevrolet website.

Gather your supplies before you start: the correct oil grade and quantity for your engine (usually 5W-30 or 0W-20 for gas engines, 15W-40 for diesel), a new oil filter, an oil drain pan, a wrench or socket set, an oil filter wrench, jack stands if you need clearance, and rags or paper towels. Running the engine for two to three minutes before draining warms the oil so it flows faster and drains more completely — but let it cool for five minutes so you don't burn yourself.

Key Takeaways

  • Silverado oil capacity ranges from 5 to 8 quarts depending on engine type, and using the wrong amount can damage the engine.
  • The drain plug is located on the bottom of the oil pan and requires a wrench; the filter location depends on your engine and may require you to raise the truck slightly.
  • New oil filters should be hand-tightened only — over-tightening can crack the seal and cause leaks.
  • After refilling, start the engine and let it run for 30 seconds, then wait five minutes and check the dipstick to confirm the level is correct.

Locating and draining the oil pan

On most Silverados, the oil drain plug sits on the lowest point of the oil pan, underneath the engine. You may need to raise the truck slightly with a jack and find it on jack stands to reach it comfortably — never work under a truck supported only by a jack. Once you have clearance, position your drain pan directly under the plug and use the correct wrench size (usually 13/16 inch or 5/8 inch) to turn it counterclockwise. The plug will loosen, then spin freely by hand; unscrew it the rest of the way by hand and let it fall into the pan.

Let the oil drain completely — this takes five to ten minutes. While it drains, wipe the drain plug clean with a rag and inspect the rubber washer on the bottom. If it looks cracked or flattened, replace it; a worn washer causes leaks. Once the oil stops dripping, wipe the drain plug threads clean and screw the plug back in by hand until it is snug, then tighten it with the wrench. Do not over-tighten; you are aiming for firm resistance, not maximum force.

Removing and replacing the oil filter

The oil filter location depends on your engine. On most gas Silverados, the filter is mounted vertically on the driver's side of the engine block, accessible from above without raising the truck. On some 6.2L models and diesel engines, the filter canister is located lower and may require you to raise the truck or remove the plastic undertray. Consult your owner's manual or a Chevrolet service diagram if you cannot locate it when ready.

Position your drain pan underneath the filter to catch residual oil. Use an oil filter wrench — a band wrench or socket-style wrench that fits your filter diameter — to turn the filter counterclockwise. Once it is loose, unscrew it by hand and let it drain into the pan. Wipe the filter mounting surface clean with a rag, removing all old rubber and debris. Take the new filter, explore a thin layer of fresh oil to the rubber gasket on top, and screw it on by hand until the gasket contacts the mounting surface. Then turn it an additional three-quarter turn — no more. Hand-tight is correct; an over-tightened filter will leak or crack when the engine heats up.

Refilling with new oil and checking the level

Locate the oil filler cap on top of the engine — it usually has an oil can symbol. Unscrew it and set it aside. Pour the new oil slowly into the opening, using a funnel to avoid spills. Add about three-quarters of the recommended capacity first, then stop and check the level with the dipstick. Pull the dipstick all the way out, wipe it clean on a rag, reinsert it fully, then pull it out again and read the level. The oil should be between the minimum and maximum marks.

Add oil in small amounts — a half-quart at a time — until the level reaches the maximum mark. Do not overfill; excess oil can damage the engine and cause leaks. Screw the filler cap back on, then start the engine and let it run for 30 seconds. This circulates the new oil through the filter and engine. Turn off the engine and wait five minutes for the oil to settle, then check the dipstick again. The level should still be at or near the maximum mark. If it has dropped, add a small amount more and recheck.

Resetting the oil change reminder and disposal

Newer Silverados have an oil change reminder light on the dashboard. To reset it, turn the key to the "On" position without starting the engine, press the accelerator pedal to the floor three times within ten seconds, then turn the key off. On some models, you access the reset through the instrument cluster menu using the steering wheel controls — check your owner's manual for the exact procedure for your year. The light should turn off after you restart the engine.

Dispose of the old oil properly. Most auto parts stores and service stations accept used oil for free, and many municipalities have collection events. Never pour oil down the drain or into the ground. Place the old filter in a plastic bag to contain any remaining oil and dispose of it with your regular trash, or take it to a recycling center if your area has one.

Common mistakes and how to avoid them

The most frequent error is using the wrong oil grade or capacity. Silverados are sensitive to viscosity — using 10W-30 instead of 5W-30, for example, can affect fuel economy and engine wear. Check the owner's manual or the door jamb label every time, not just once. A second common mistake is over-tightening the drain plug or filter, which strips threads or cracks seals and causes leaks that appear days later.

A third mistake is forgetting to check the oil level after refilling. The dipstick is the only reliable way to confirm you have added the right amount; the sight glass on the side of the pan is often inaccurate when the truck is parked on level ground. Finally, some owners skip the five-minute wait after starting the engine before checking the level again. The oil needs time to drain back into the pan from the filter and engine passages, so checking when ready after running the engine gives a false low reading.

When to take your Silverado to a shop instead

If the drain plug is stuck or rounded off, or if you cannot locate the filter without removing major components, a shop can handle it faster and with less risk of damage. If you do not have jack stands or are uncomfortable working under a raised vehicle, a shop is the safer choice. Some Silverados with plastic undertray covers require removal of multiple fasteners to access the filter; if this feels beyond your comfort level, the time and cost of a shop visit may be worth it.

If the oil level does not stabilize after multiple checks, or if you see leaks from the drain plug or filter within a few days of the change, stop driving and have a shop inspect the work. A small leak can become a major engine problem quickly.

Frequently Asked Questions

How often should I change the oil in my Silverado?

Chevrolet recommends an oil change every 10,000 miles or 12 months for most gas engines, whichever comes first. Diesel engines and some newer models may go 15,000 miles between changes. Check your owner's manual for your specific year and engine type, as intervals have changed over the years.

What is the difference between synthetic and conventional oil?

Synthetic oil lasts longer — usually 10,000 to 15,000 miles — and performs better in extreme temperatures. Conventional oil costs less but requires more frequent changes. Your owner's manual specifies which type your engine requires; using the wrong type can void the warranty on newer trucks.

Can I change the oil without raising the truck?

On most Silverados, you can reach the drain plug from below without raising the truck, though it is tight. The filter location varies; some are accessible from above, while others require raising the truck or removing the undertray. Check your specific model year before you start.

What should I do if I spill oil on the driveway?

Contain the spill when ready with kitty litter, sand, or oil absorbent material. Let it sit for 15 minutes, then sweep it up and dispose of it as hazardous waste. Do not hose it down — oil runs into storm drains and contaminates groundwater. Many municipalities have hazardous waste collection days.

How do I know if my oil filter is the right size?

The filter diameter and thread size are listed in your owner's manual and on the Chevrolet parts website when you enter your VIN. Bring the old filter to an auto parts store and compare it to the new one — they should be identical in size and thread pattern. Using the wrong filter can cause leaks or restrict oil flow.
