Quick Answer

2023-2024 Chevrolet Express 2500 uses 5.50 QTS. (5.2 L) — API - SAE 5W-30 Note: DEXOS1 Gen3 Full synthetic engine oil. 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..
