* Model and Year: Gas mileage varies dramatically between different Dodge Ram models equipped with Cummins engines. A 2018 Ram 1500 with a 6.7L Cummins will have much different fuel economy than a 2023 Ram 3500 with the same engine.
* Engine Configuration: Even within the same model year, there are often different Cummins engine options. For example, a Ram 2500 might have a 6.7L Cummins or a 6.4L Hemi gas engine.
* Transmission: The transmission type and gearing can significantly affect fuel efficiency.
* Drivetrain: A 4x4 configuration will generally get worse fuel economy than a 2WD.
* Driving Habits: Your driving style, road conditions, and cargo load all play a huge role in your fuel economy.
* Modifications: Aftermarket modifications can impact fuel mileage, either positively or negatively.
Instead of a single figure, here's how to get a better understanding of potential fuel economy:
1. Look up EPA estimates: The official EPA fuel economy ratings are a great starting point. You can find these on the EPA website or on the window sticker of a new vehicle. Keep in mind that these are estimates and your actual mileage may vary.
2. Research specific model and year: Online forums and review websites are great resources for real-world fuel economy reports from owners of specific models.
3. Consider fuel economy enhancing options: Features like an automatic stop-start system, aerodynamic body modifications, and lightweight wheels can help improve fuel efficiency.
General Tips for Best Fuel Economy:
* Drive smoothly: Avoid aggressive acceleration and braking.
* Maintain proper tire pressure: Underinflated tires reduce fuel efficiency.
* Minimize cargo weight: Carry only what you need.
* Avoid idling: Turn off the engine when stopped for extended periods.
* Use cruise control on highways: This can help maintain a steady speed and improve fuel economy.
Remember: The best gas mileage from your Cummins Dodge diesel is ultimately determined by your specific vehicle, driving habits, and other factors. Researching your specific model and incorporating fuel-saving strategies will help you maximize your fuel efficiency.
