How much oil does a 1998 Chevy Astro van take?

The amount of oil a 1998 Chevy Astro van takes depends on the engine. There were several engine options available for that year. You must check your owner's manual for the specific oil capacity for your van's engine.

The manual will clearly state the amount of oil needed for a complete oil change. Failing to find the manual, you can usually find this information online by searching for "[your engine type] oil capacity." You will need to know your engine size (e.g., 4.3L V6) to do this accurately.
