What kind of oil does a 2005 Chevy Colorado take?

The type of oil a 2005 Chevy Colorado takes depends on the engine it has. There were several engine options available that year. To know for sure, you need to check your owner's manual. This is the most reliable source.

However, generally, 2005 Chevy Colorados used either 5W-30 or 10W-30 conventional or synthetic motor oil. The owner's manual will specify the exact weight and type (conventional, synthetic blend, or full synthetic) recommended by General Motors for your specific engine. It will also specify the oil capacity.
