However, this is just a guideline. Several factors can influence when you *should* actually change them:
* Driving conditions: Frequent short trips, stop-and-go traffic, or towing will shorten the lifespan of your spark plugs.
* Engine performance: If you notice any signs of misfiring (rough idle, hesitation, loss of power, poor fuel economy), it's time to check your spark plugs and potentially replace them.
* Visual inspection: If you're mechanically inclined, you can periodically inspect the spark plugs yourself. Look for signs of wear such as excessive fouling (black, oily, or wet), erosion, or cracking.
It's best to consult your owner's manual for the precise recommendations from Chevrolet for your specific engine type. The manual might offer a more specific mileage or time interval. If you're unsure, it's always better to err on the side of caution and have your spark plugs inspected by a qualified mechanic during routine maintenance.
