Oil capacity by engine
| Engine | Oil Type (viscosity) | Capacity w/ Filter | Capacity w/o Filter | Notes |
|---|---|---|---|---|
| Escalade EXT | API - SAE 5W-30 | 6.00 QTS. | — | Use oil that meets GM Standard GM6094M. DO NOT use other viscosity oils such as SAE 20W-50. For areas of extreme cold, where temperatures fall below -20Deg.F (-29Deg.C), it is recommended a SAE 5W-30 synthetic oil or a SAE 10W-30 oil. Both will provide easier cold starting and better protection for your engine at extremely low temperatures. |
