What’s the Best Way to Improve the Fuel Economy of a Ram 1500 EcoDiesel?

As the owners of Ram 1500 EcoDiesel trucks, you understand the importance of fuel economy. Whether you utilize your truck for towing, daily commutes, or cross-country road trips, the better the mpg, the more you save at the pump. You may wonder, "Can I improve the fuel economy of my EcoDiesel engine even further?" The answer is a resounding yes. In the following sections, we’ll explore various strategies to maximize your Ram’s mpg, from regular maintenance to air intake modifications.

1. Regular Maintenance and Timely Repairs

Regular maintenance is critical to ensure your Ram 1500 EcoDiesel operates at peak performance. Just like any other diesel engine, neglect can result in poor fuel economy and reduced torque. Regular maintenance includes oil changes, air filter replacements, and checking the exhaust system for leaks.

Oil changes are crucial for maintaining the engine’s performance. Dirty oil can cause the engine to work harder and consume more fuel. Most manufacturers recommend changing the oil every 5,000 miles but consult your owner’s manual for the specific interval.

Similarly, a clogged air filter can reduce the engine’s efficiency. The engine requires a steady stream of clean air for proper combustion. A dirty air filter restricts this, making the engine work harder and consume more fuel.

Finally, exhaust leaks can significantly impact your Ram’s fuel economy. The exhaust system helps control the engine’s temperature and remove waste gases. Any leaks will make the engine run hotter and less efficiently, so ensure any issues are addressed promptly.

2. Optimize Air Intake

Air intake plays a crucial role in the engine’s combustion process: the more air it receives, the better it performs. Upgrading your Ram’s air intake system can help to improve fuel economy. A cold air intake system draws cooler air into the engine, increasing combustion efficiency and producing more power with less fuel. This not only boosts your Ram’s performance but also its fuel economy.

An engine that breathes better also accelerates better, reducing the need to push the gas pedal hard. This results in less fuel consumption and better mpg figures. While the upfront cost of these systems can be high, the savings in fuel expenses over time can offset the initial investment.

3. Mindful Driving Habits

Your driving habits significantly affect your Ram 1500 EcoDiesel’s fuel economy. Rapid acceleration, excessive speed, and heavy towing can all reduce mpg.

Driving at a consistent speed and avoiding quick starts and stops can improve fuel economy. The Ram 1500 EcoDiesel is designed with a torque-focused engine, which performs best at moderate speeds.

Additionally, excessive towing can negatively impact fuel economy. While the Ram 1500 EcoDiesel excels in towing capacity, consistently towing heavy loads can strain the engine, leading to increased fuel consumption.

4. Tire Maintenance

Tire maintenance plays a crucial role in fuel economy. Underinflated tires increase rolling resistance, making the engine work harder and subsequently consume more fuel. Regularly checking tire pressure and keeping them at the recommended level can improve fuel efficiency by up to 3%.

Using the right type of tires can also impact fuel consumption. For instance, all-terrain tires might offer excellent off-road capabilities, but they can decrease fuel economy due to their higher rolling resistance. If you mainly use your Ram 1500 EcoDiesel for highway driving, consider using highway tires for better mpg.

5. Utilize Fuel-Efficient Technologies

Many modern trucks, including the Ram 1500 EcoDiesel, come equipped with technologies designed to enhance fuel economy. Features such as automatic start/stop systems, aerodynamic designs, and advanced transmission systems contribute to better mpg.

The start/stop system shuts off the engine when the truck is idling, such as at a red light, and restarts it when you’re ready to move. This prevents unnecessary fuel consumption during idle periods.

The Ram 1500 EcoDiesel’s aerodynamic design also contributes to its fuel efficiency. Its sleek design reduces air resistance, which can improve fuel economy, especially at high speeds.

Lastly, the truck’s advanced transmission system ensures optimal gear shifting, which can significantly enhance fuel efficiency. Understanding and utilizing these technologies can help maximize your Ram 1500 EcoDiesel’s fuel economy.

In summary, improving the fuel economy of your Ram 1500 EcoDiesel involves a combination of regular maintenance, performance upgrades, mindful driving habits, and proper tire care. By paying attention to these areas, you can maximize your truck’s mpg, save money at the pump, and enjoy the exceptional performance your Ram 1500 EcoDiesel was designed to deliver.

6. Powertrain Control System

The powertrain control system is another aspect that greatly influences fuel economy in Ram 1500 EcoDiesel trucks. This system controls the engine and other components that help the vehicle move. It operates in a way that the vehicle’s performance is optimized while reducing fuel consumption.

You can invest in a powertrain control module, a device that alters the electronic control signals of your vehicle’s engine to enhance performance and efficiency. By optimizing your engine’s performance, you can improve fuel economy significantly.

Make sure the controller settings are tuned to improve fuel economy. You might need to compromise slightly on power but the fuel savings will be worth it. Also, keep in mind that it’s crucial to find a balance. While aggressive tuning might lead to more power, it may also result in more fuel consumption and engine stress.

7. Additional Tips on Fuel Economy

Another way to improve your fuel economy is by reducing the weight of your Ram 1500 EcoDiesel. Excess weight puts more strain on the engine, causing it to consume more fuel. Try to keep your vehicle as light as possible.

Turning off the air conditioning can also improve fuel economy as the A/C system uses a lot of energy. However, this may not be practical during hot summer days.

Furthermore, limiting the use of power-demanding accessories can also aid in improving fuel economy. For example, using the heated seats or radio excessively can increase fuel consumption.


Improving the fuel economy of your Ram 1500 EcoDiesel is not just about saving money at the pump. It also contributes to reducing your carbon footprint and prolonging the lifespan of your truck.

This can be achieved by adopting regular maintenance habits, optimizing air intake, maintaining tires, mindful driving, and maximizing the use of fuel-efficient technologies. Investing in a powertrain control module and reducing unnecessary weight can also contribute to better fuel economy.

By adhering to these strategies, you can enjoy the best of both worlds: excellent performance and superior fuel efficiency from your Ram 1500 EcoDiesel. Remember, good fuel economy begins with you. It’s all about making the right choices, both on and off the road.
