What type oil for 2004 Chevy Colorado truck?

The recommended oil type for a 2004 Chevy Colorado depends on the engine it has. There were several engine options available that year. To determine the correct oil, you need to find your engine's displacement (e.g., 2.8L, 3.5L) and then check your owner's manual.

The owner's manual will specify the:

* Oil type: This will likely be a Society of Automotive Engineers (SAE) viscosity grade (like 5W-30, 10W-30, etc.) and may also specify an API service classification (like SM, SN, or newer).

* Oil capacity: The amount of oil your engine needs.

Without knowing your engine size, I cannot give you a definitive answer. However, 5W-30 is a commonly recommended oil for many 2004 Chevy Colorado engines, but you must verify this with your owner's manual. Using the incorrect oil can damage your engine.
