Are Dodge Chargers Good On Gas? 

Be sure to check the owner's manual twice for the correct octane rating for the Dodge Chargers engine. 

If you are driving heavily, then expect low fuel mileage, but if you are driving normally, 

and avoiding using the gas pedal as much as you can, your Charger will achieve better mileage. 

Premium gas generally has higher octane ratings than regular unleaded, 

and using premium gas in a Dodge Charger does not hurt the engine. 

While premium gas is available for both 3.6-liter V6s and Hemi engines, 

it probably will not have much of an impact on performance or fuel economy. 

It may benefit your engine greatly if you are willing to pay extra for premium fuel in higher-performance cars with higher-compression engines. 

Higher-performance engines usually have higher compression, requiring higher-octane fuel to achieve optimal performance. 

The highest-performance engines, R/T Scatpack, Daytona 392, SRT 392, and SRT Hellcat, require high-quality [91 RON] or higher-grade fuel. 

In addition to the Dodge Chargers mentioned above, cars that have a turbocharger typically require premium fuel.
