2022 Chevrolet Silverado 3500HD — Oil Capacity & Filter

The 2022 Chevrolet Silverado 3500HD takes 8.0 quarts (7.6 liters) of engine oil with filter for the 6.6L gas V8 and 10.0 quarts (9.5 liters) with filter for the 6.6L Duramax diesel V8.

Quick answer

• Oil capacity (with filter):
  • 6.6L Gas (L8T): 8.0 qt (7.6 L)
  • 6.6L Duramax Diesel (L5P): 10.0 qt (9.5 L)
• Recommended oil weight/viscosity:
  • Gas: 0W-20
  • Diesel: 15W-40 (5W-40 full-synthetic for cold climates)
• Oil type/spec:
  • Gas: GM dexos1 Gen3 (or dexos1-approved), API SP
  • Diesel: API CK-4 (or better), appropriate for DPF-equipped engines
• Oil filter part numbers:
  • Gas OEM: ACDelco PF63; popular cross-refs: Fram XG10575, Wix 57060, Mobil 1 M1-113A
  • Diesel OEM: Consult dealer for the correct PN for your VIN (common listings include ACDelco PF2262G or PF2232); popular cross-refs often used: Fram XG9100, Wix 57202, Mobil 1 M1-303A — verify fitment by VIN

Capacity by engine option

Oil change interval

• Normal service:
  • Gas (L8T): Follow the Oil Life Monitor (OLM), up to ~7,500 miles or 1 year, whichever comes first.
  • Diesel (L5P): Follow the OLM, commonly up to ~10,000 miles or 1 year under light/normal duty.
• Severe service (heavy towing, extensive idling, dusty sites, short-trip/cold operation):
  • Gas (L8T): 5,000 miles/6 months.
  • Diesel (L5P): 5,000–7,500 miles/6 months depending on duty cycle and soot/fuel dilution; always defer to the OLM if it calls for sooner service.

Drain plug torque

• 6.6L Gas (L8T) drain plug torque: 18 lb-ft (25 N·m)
• 6.6L Duramax (L5P) drain plug torque: 31 lb-ft (42 N·m)
• Crush washer/gasket note: Many GM plugs use an integral gasket; replace the sealing washer if separate, and inspect/replace the plug gasket if it’s nicked, deformed, or hardened.

How to change the oil

1. Warm the engine to operating temp, then shut off and let it sit a few minutes.
2. Raise and support the truck safely if needed; remove any lower shields/skid plates for access.
3. Place a drain pan, remove the drain plug, and let oil drain completely.
4. Replace/inspect the drain plug gasket; reinstall the plug and torque to spec (see above).
5. Spin off the oil filter. Clean the filter pad. Lightly oil the new filter’s gasket.
6. Gas (L8T): Install the new filter hand-tight plus 3/4 turn. Do not pre-fill.
7. Diesel (L5P): Pre-fill the new filter with clean oil if orientation allows, then install hand-tight plus 3/4 turn.
8. Fill the crankcase with the specified amount and grade.
9. Start the engine, check for leaks, shut down, wait a few minutes, recheck level, and top off as needed.
10. Reset the OLM through the driver information center.

Common issues / tips for this generation (2020–2023 HD)

• L8T gas engines are designed for 0W-20 dexos1 oil even when towing; avoid thicker viscosities unless directed by GM.
• Initial break-in can show modest oil consumption; monitor and top off as the rings seat. Persistent consumption should be inspected under warranty/TSB guidance.
• Duramax L5P engines can see fuel dilution of the oil with frequent short trips and active DPF regens; shorten intervals if the oil level rises or if the OLM drops quickly.
• Pre-filling the diesel oil filter helps reduce dry-start time after a change; keep the center inlet clean while filling.
• Always verify diesel oil filter part number by VIN. Catalogs may list different PNs (PF2262G vs PF2232) depending on build; using the wrong filter can cause sealing issues.
• Watch for double-gasket mistakes when removing an old filter; ensure the old gasket isn’t stuck to the block.
• Reinstall underbody shields properly—missing fasteners can lead to vibration/noise at highway speeds.
