What type of oil does a 2005 Chevy Tahoe need?

A 2005 Chevy Tahoe requires the type of oil specified in its owner's manual. However, generally speaking, for a 2005 Tahoe with a gasoline engine, 5W-30 is a common and often recommended oil viscosity.

Crucially, you should consult your owner's manual. The manual will specify the exact type of oil (conventional, synthetic blend, or full synthetic) and the recommended viscosity for your specific engine. Using the wrong type of oil can damage your engine.
