To be more precise, it usually uses unleaded gasoline with an octane rating of 87 or higher.
However, there are a few caveats:
* Engine options: The 2001 Suburban was available with a variety of engines. Some were more powerful and required higher octane fuel. Consult your owner's manual for specific fuel recommendations based on your engine type.
* Flex-fuel: A small percentage of 2001 Suburbans may have been equipped with a flex-fuel engine capable of running on both gasoline and E85 (a blend of gasoline and ethanol). If your Suburban has a flex-fuel badge or sticker, you can use either fuel type.
Always refer to your owner's manual for the most accurate and up-to-date information on fuel requirements for your specific 2001 Chevrolet Suburban.
