The 2022 Suburban requires Dexos1 Gen 2 synthetic motor oil with a viscosity of 0W-20 for its common gasoline engines.
Oil specifications for the 2022 Suburban
Below are the core requirements that apply to the gasoline-powered versions of the 2022 Suburban. This section helps you understand the exact oil type, viscosity, and capacity you should use.
Gasoline engines: 5.3L EcoTec3 V8 and 6.2L V8
Before listing the precise requirements, here is a concise overview of what you should use and how much you’ll need.
- Oil type: Dexos1 Gen 2 synthetic motor oil
- Viscosity: 0W-20
- Oil type should be fully synthetic and Dexos1 Gen 2 approved; do not use conventional motor oil
- Oil capacity: Approximately 8 quarts (with filter)
- Maintenance note: Use the vehicle’s Oil Life Monitor and follow GM’s service intervals as outlined in the owner’s manual
For both gasoline engines, adhering to Dexos1 Gen 2 0W-20 helps optimize protection, fuel economy, and engine longevity. Always double-check your specific build and regional recommendations in the owner's manual or on the under-hood information label.
Diesel option and special cases
Some 2022 Suburban models may be equipped with the 3.0L Duramax diesel. Diesel engine oil requirements differ from the gasoline engines, typically requiring a Dexos2-rated oil with a different viscosity specification. If your Suburban is the diesel variant, consult the owner's manual or GM’s official guidance to confirm the exact oil specification and capacity for your configuration.
Summary
In short: for the common 2022 Suburban gasoline models (5.3L and 6.2L), use Dexos1 Gen 2 synthetic oil with a viscosity of 0W-20, and plan on about 8 quarts of oil with a new filter. If your Suburban uses the diesel Duramax option, refer to the manual for Dexos2-approved oil and the correct viscosity. Always verify the specification for your exact vehicle and climate.
