What Does ‘ECO’ Mean Under MPG on a 2004 RAM?

The term "eco" under the MPG, on a 2004 RAM, refers to the Eco mode feature incorporated into the vehicle's design. It’s a noteworthy fuel-saving functionality found in various car models, provided by several manufacturers. Essentially, this mode entails the engine computer being directed to activate a specific program aimed at optimizing fuel efficiency rather than prioritizing performance. By utilizing this Eco mode, drivers can potentially experience improved gas mileage without sacrificing too much power. While each manufacturer may implement this mode differently, the overall objective remains the same: to maximize fuel efficiency and minimize emissions, ultimately promoting a more eco-friendly driving experience.

What Is the Eco Mode on a 2017 Ram 5.7 Hemi?

The eco mode on a 2017 Ram 5.7 Hemi is a feature designed to promote fuel efficiency and reduce emissions during driving. This automatic setting is available on all modern Ram 1500s equipped with V8 engines. By engaging eco mode, drivers are notified when they’re driving in a manner that maximizes fuel efficiency.

By moderating the available power output based on the drivers input and the vehicles current load, the engine can operate more efficiently, resulting in reduced fuel consumption. This feature is particularly useful during steady highway cruising or in traffic conditions where constant acceleration and deceleration are required.

Another significant advantage of the eco mode is it’s contribution to reducing emissions. This is achieved by carefully controlling the combustion process and reducing unnecessary fuel consumption, resulting in a greener and more environmentally friendly driving experience.

It can be easily activated or deactivated using the control interface provided by the manufacturer. With the touch of a button, drivers can choose to engage or disengage the eco mode, depending on their preferences, driving conditions, or immediate needs.

It offers drivers a convenient way to monitor and improve their driving habits while benefiting from optimized engine performance.

When ECO Mode is activated in a Dodge Ram, you’re driving in a way that allows the engine to conserve energy and perform more efficiently. Often, when ECO Mode is engaged, your V8 engine has also switched to MDS Mode, which restricts the number of cylinders in use and increases fuel economy. This feature aims to enhance your vehicle’s gas mileage without compromising on performance. So, let’s explore whether Ram ECO Mode truly saves gas and how it affects your driving experience.

Does Ram Eco Mode Save Gas?

The combination of these features can indeed result in savings on gas consumption. By reducing the workload on the engine, ECO Mode helps to reduce fuel consumption, especially during highway driving where maintaining a consistent speed is more feasible. The MDS Mode, on the other hand, optimizes fuel efficiency by shutting down unneeded cylinders and running on fewer cylinders when power demands are lower.

In addition to the engine functions, ECO Mode in the Ram also adjusts other vehicle systems to help save gas. It may modify throttle response, transmission shift points, and even the air conditioning system to reduce power demands and improve fuel economy.

It’s important to note that the extent of fuel savings with Rams ECO Mode can vary depending on driving conditions, habits, and other factors. While it can make a significant difference during highway cruising, the impact may not be as prominent in stop-and-go city driving or when towing heavy loads.

By taking a comprehensive approach to fuel efficiency, owners of Ram trucks can enjoy the benefits of ECO Mode while contributing to a greener and more sustainable future.

What Are Some Tips for Maximizing Fuel Savings With ECO Mode?

  • Drive at a consistent speed to avoid unnecessary acceleration and deceleration.
  • Avoid excessive idling by turning off the engine when parked or waiting for extended periods.
  • Use cruise control on highways to maintain a steady speed.
  • Avoid carrying unnecessary weight in your vehicle, as it can reduce fuel efficiency.
  • Plan your route efficiently to avoid traffic congestion and unnecessary detours.
  • Maintain regular maintenance and service checks to ensure your vehicle is running optimally.
  • Keep your tires properly inflated to improve fuel economy.
  • Reduce air conditioning usage by utilizing natural ventilation whenever possible.
  • Avoid aggressive driving maneuvers, such as rapid acceleration and hard braking.
  • Consider using eco-friendly fuels or alternative energy sources for your vehicle.

The 2015 Ram 1500 EcoDiesel boasts impressive fuel efficiency, surpassing the estimates for it’s V-6 and 5.7-liter Hemi counterparts. According to EPA ratings, this model achieves 19 mpg in the city and 27 mpg on the highway. In real-world testing, drivers have seen even better results, obtaining an average of 21 mpg in combined driving conditions.

How Many Miles Per Gallon Does a 2015 Ram 1500 EcoDiesel Get?

The 2015 Ram 1500 EcoDiesel is known for it’s impressive fuel efficiency. With EPA ratings of 19 mpg in the city and 27 mpg on the highway, it outperforms other versions of the Ram 1500. For instance, the V-6 1500 Crew Cab only achieves estimated fuel economy of 16 mpg in the city and 23 mpg on the highway. Similarly, the truck equipped with the 5.7-liter Hemi engine and eight-speed automatic transmission has lower fuel economy estimates of 15 mpg in the city and 21 mpg on the highway.

On our tests, it returned a commendable 21 mpg in combined driving. This makes it a great choice for those who prioritize fuel economy, especially for those who frequently commute in urban areas where higher fuel efficiency is desired.

It delivers a balanced combination of power and efficiency, offering 240 horsepower and 420 lb-ft of torque. This allows the Ram 1500 to provide ample acceleration and towing capabilities while still achieving excellent fuel economy.

Additionally, the EcoDiesel engine is equipped with advanced technology such as selective catalytic reduction (SCR) and a diesel particulate filter (DPF), which help reduce emissions and improve overall environmental performance.

With EPA ratings of 19 mpg city and 27 mpg highway, and a real-world combined driving fuel economy of 21 mpg, it offers a great balance of power and efficiency. The advanced technology and emission reduction features of the EcoDiesel engine make it an environmentally-friendly choice as well.

Comparison of the Fuel Efficiency of the 2015 Ram 1500 EcoDiesel to Other Similar Trucks

The 2015 Ram 1500 EcoDiesel was known for it’s impressive fuel efficiency compared to other similar trucks of it’s time. It boasted a powerful yet efficient engine that allowed for better mileage per gallon. It’s ability to deliver good fuel economy made it a popular choice for truck drivers who valued both power and savings at the pump. However, it’s worth noting that fuel efficiency can vary based on various factors such as driving habits, load capacity, and terrain.


While specific implementations may vary between vehicles, the overarching goal remains the same – to strike a balance between performance and fuel economy.
