How many miles between an oil change for a Chevy astro van?

The recommended oil change interval for a Chevy Astro van depends on several factors, including the year of the van, the type of oil used (conventional, synthetic blend, or full synthetic), and your driving conditions (mostly city driving vs. mostly highway driving).

However, a general guideline is to change the oil every 3,000 to 5,000 miles for conventional oil and every 7,500 to 10,000 miles for full synthetic oil. Always consult your owner's manual for the most accurate and up-to-date recommendation for your specific Chevy Astro van's year and engine. The manual will give you the best advice based on the manufacturer's specifications.
