* Regular Unleaded Gasoline: This is the most common fuel type for gasoline-powered vehicles, and it's what most Dodge Grand Caravans from 2008 use.
* E85 (85% Ethanol Blend): Some 2008 Grand Caravans were equipped with a flex-fuel engine that can run on either regular unleaded gasoline or E85. You can check the fuel filler cap or the owner's manual to see if your specific Grand Caravan is flex-fuel capable.
Important Note: It's important to use the correct fuel for your vehicle. Using the wrong fuel type can damage your engine.
