How many miles per gallon does a 2017 Ram 3500 diesel get?

The 2017 Ram 3500 diesel model is known for its impressive towing capacity and power, but how does it perform when it comes to fuel efficiency? According to the latest data, the 2017 Ram 3500 diesel can achieve an average of 18-20 miles per gallon (mpg) in combined city and highway driving.


Factors Affecting Fuel Economy


The fuel economy of the 2017 Ram 3500 diesel can vary depending on several factors, including driving conditions, load, and driving style. Here are some key considerations:



  • Engine and Transmission: The 2017 Ram 3500 diesel is equipped with a 6.7-liter Cummins turbocharged diesel engine, paired with either a six-speed manual or six-speed automatic transmission. The engine and transmission combination can impact fuel efficiency.

  • Driving Conditions: Driving on highways, with minimal stops and starts, can improve fuel economy compared to city driving with more frequent braking and acceleration.

  • Load and Towing: Hauling heavy loads or towing a trailer can significantly reduce the 2017 Ram 3500 diesel's fuel efficiency, as the engine has to work harder to move the additional weight.

  • Driving Style: Aggressive acceleration, high-speed driving, and frequent braking can all negatively impact the 2017 Ram 3500 diesel's fuel economy.


It's important to note that the fuel economy figures provided by the manufacturer are based on EPA testing, which may not reflect real-world driving conditions. Actual fuel efficiency can vary depending on the factors mentioned above.


Improving Fuel Economy


To maximize the fuel efficiency of your 2017 Ram 3500 diesel, consider the following tips:



  • Maintain Proper Tire Pressure: Ensure that your tires are inflated to the recommended pressure, as underinflated tires can increase rolling resistance and reduce fuel economy.

  • Use Recommended Fuel: Use the recommended grade of diesel fuel, as specified in your owner's manual, to ensure optimal engine performance and fuel efficiency.

  • Avoid Excessive Idling: Idling your engine can significantly reduce fuel efficiency, so try to minimize unnecessary idling whenever possible.

  • Plan Ahead: Combine multiple errands into one trip and avoid unnecessary acceleration and braking to improve your overall fuel economy.


By following these tips and being mindful of your driving habits, you can help maximize the fuel efficiency of your 2017 Ram 3500 diesel and get the most out of your vehicle's performance.

How many miles per gallon does a 2017 Dodge RAM 3500 diesel get?


The Ram 3500 with Cummins Diesel is available in three engine options: a 6.7L Cummins Turbo Diesel I6, a 6.4L HEMI V8, and a 6.4L High Output HEMI V8. The 6.7L Cummins Turbo Diesel I6 offers the highest MPG at 16-21, while the 6.4L HEMI V8 and 6.4L High Output HEMI V8 offer 13-18 and 12-16 MPG, respectively.



How many miles per gallon does a RAM 3500 diesel get while towing?


A Ram 3500 with a diesel engine typically gets 9-14 mpg while towing, though this can vary significantly based on the weight being towed, terrain, and speed. Heavier loads, steep grades, and higher speeds will decrease the mpg, while lighter loads and flatter, lower speeds will result in better fuel economy, with some users reporting up to 11-12 mpg when towing around 10,000 lbs at 62 mph.

Factors affecting towing MPG

  • Weight of the trailer: The heavier the trailer, the lower your MPG will be. 
  • Terrain: Driving in hilly or mountainous areas will significantly decrease fuel economy compared to driving on flat roads. 
  • Speed: Driving at higher speeds will reduce your MPG. 
  • Axle ratio: Different axle ratios can impact fuel economy. 
  • Engine and model year: Newer models with high-output engines may have different performance characteristics compared to older ones. 
  • Environmental factors: Wind speed and temperature can also play a role. 

Examples of real-world MPG while towing
  • Towing 16,000 lbs with a 2019 model yielded approximately 9.5 mpg. 
  • Towing a 9,999 lbs fifth wheel at 62 mph resulted in 11-12 mpg. 
  • Pulling a 24,000 lb trailer resulted in 8-9 mpg in hilly terrain. 
  • A user reported 9.5 mpg while towing a 16,500 lb trailer at 70 mph, versus 16.5 mpg empty at the same speed.

What is the gas mileage on a 2017 6.7 Cummins?


2017 6.7. I'm getting 14-16 mpg as a daily. Towing it's less.



How many miles per gallon does a RAM 3500 6.7 diesel get?


The Ram 3500 with a 6.7L Cummins engine typically gets 16–21 mpg combined, with highway mileage being better than city mileage. Expect around 17 mpg in the city and 22 mpg on the highway for a 4x4 model, though these numbers can range from 15 to 25 mpg depending on factors like driving style, load, and the specific truck configuration. 
Fuel economy by driving type

  • City: Around 17 mpg, but can be as low as 13-14 mpg depending on driving conditions. 
  • Highway: Typically around 22 mpg, though it can reach 25 mpg under optimal conditions. 
  • Towing: Varies significantly, but can range from 10-12 mpg when towing heavy loads. 

Factors that affect MPG
  • Towing: Heavier loads will decrease fuel economy. Towing can reduce MPG to 10-12 mpg or lower, depending on the load's weight and your speed. 
  • Driving style: Aggressive driving habits will negatively impact fuel efficiency.
  • Tire and wheel size: Larger or off-road tires, especially on a leveled truck, can decrease MPG. 
  • Engine and transmission: Different engine outputs (standard vs. high output) and transmission options can affect performance and fuel economy. 
  • Emissions system: The truck's emissions calibration and DPF regeneration cycles can impact MPG.
