Engine Oil
For most gasoline engines in the 2020 Chevrolet Silverado 1500, the factory recommendation is a motor oil meeting Dexos1 Gen2 specifications. Viscosity will vary by engine. Common viscosities include 0W-20 or 5W-30. Always verify the specific viscosity and Dexos1 generation required for your engine in your owner's manual or OEM service information. Using an oil that doesn't meet the Dexos1 Gen2 specification on gasoline engines can lead to potential engine damage and may void your warranty. Diesel engines (e.g., 3.0L Duramax) will require a different oil specification, typically an API CK-4 rated oil, with a viscosity such as 0W-20 or 5W-30 specific to diesel applications.
Intervals: Typically, oil change intervals are recommended every 7,500 miles or 12 months, whichever comes first, under normal driving conditions. However, the Silverado
