| Engine Oil | w/Filter | 8.00 QTS. | 7.57 L | API - SAE 0W-20 | The engine requires engine oil approved to the dexos specification. Oils meeting this specification can be identified with the dexos certification mark. Look for and use only an engine oil that displays the dexos certification mark of the proper viscosity grade. SAE 0W-20 GM P/N 19259487 (Canadian P/N 19289784) is the best viscosity grade for the 5.3L and 6.2L V8 engines. Cold Temperature Operation: In an area of extreme cold, where the temperature falls below -29Deg. C (-20Deg. F), an SAE 0W-30 oil should be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, be sure to always select an oil that meets the required specification, dexos. NOTE: The engine oil capacity has been updated from 8.50 qts to 8.0 qts in reference to GM's Document ID: 3998244, #PIP5231A. | S | |
