What grade fuel can you use in the 08 HEMI MDS engine?

The 2008 Dodge HEMI with MDS (Multi-Displacement System) requires a minimum of 89 octane fuel. While it might run on 87, using 89 octane or higher is recommended for optimal performance and to prevent potential engine damage. The owner's manual should explicitly state the recommended fuel grade.
