How much oil does a Chevy 3500HD take?

The engine oil capacity for a Chevy Silverado 3500HD depends on the powertrain: about 6 quarts (roughly 5.7 liters) for the 6.0L gas V8, and about 11 quarts (roughly 10.5 liters) for the 6.6L Duramax diesel, including the oil filter.

In practice, precise figures can vary by model year and configuration. Below is a breakdown by engine, along with guidance on the recommended oil types and where to check for year-specific details.

Engine oil capacity by powertrain

The following figures reflect official capacities with the oil filter installed, as listed by GM for current Silverado 3500HD configurations. If your exact year differs, consult the owner's manual for the precise specification.

• Gasoline 6.0L V8: Approximately 6 quarts (about 5.7 L) of engine oil with filter.


• Diesel 6.6L Duramax: Approximately 11 quarts (about 10.5 L) of engine oil with filter.

Using the correct fill量 helps ensure proper lubrication and oil pressure. If your oil level is near or above the full line after a change, you’re in the right range.

Oil type and viscosity recommendations

Different engines require different oil types and viscosities. The guidelines below reflect current GM recommendations for Silverado 3500HD engines; always verify with your manual for your exact year and configuration.

Gasoline 6.0L V8

Recommended oil: Dexos1 Gen 2 5W-30 (full synthetic preferred; conventional approved per manual).

• Dexos1 Gen 2 5W-30 is the standard specification for most 6.0L V8 3500HD applications.

Using the recommended oil type helps protect the engine and maintain warranty coverage. Verify any climate-specific allowances in your manual.
