* Every 30,000-40,000 miles: This should include a spark plug replacement, air filter replacement, fuel filter replacement (if applicable, check your owner's manual), and a thorough inspection of all other components. This is closer to what a "tune-up" encompassed in older vehicles.
* Every 10,000-15,000 miles: Oil changes and filter replacements are crucial and should happen much more frequently than the above.
* Consult your owner's manual: This is the single best source for specific maintenance recommendations for your 2000 Corvette. It will detail recommended service intervals for your specific model.
Important Note: Don't just rely on mileage. If you notice any problems like decreased performance, rough idling, or poor gas mileage, you should have your car checked by a mechanic sooner rather than later, regardless of mileage.
