How do you reset the computer on a 2006 Chevy silverado after an oil change?

There's no "computer reset" needed on a 2006 Chevy Silverado after an oil change in the sense of pressing a button or following a specific procedure like some modern cars. The onboard computer doesn't require a reset simply because the oil was changed.

The only thing you might be thinking of is resetting the oil life monitor. This is a feature that estimates when your next oil change is due based on driving habits. To reset the oil life monitor on a 2006 Silverado, you'll need to consult your owner's manual. The procedure typically involves a series of steps using the vehicle's instrument cluster controls (buttons on the steering wheel or dash). The exact steps may vary slightly depending on the trim level and options. Look for a section on "Oil Life System Reset" or something similar.
