What octane does a 2001 Dodge Ram use?

The recommended octane rating for a 2001 Dodge Ram depends on the engine. You need to check the sticker on the driver's side doorjamb or your owner's manual. It will specify the recommended octane rating (e.g., 87, 89, or 91 octane). Using a lower octane than recommended can reduce performance and fuel economy, while using a higher octane than recommended won't necessarily provide any benefit.
