Fuel economy of a 2024 Chevy Duramax
The fuel economy of a 2024 Chevy Duramax depends on several factors, including driving conditions, terrain, and whether or not the vehicle is being used for towing.
According to a user on the Duramax Forum, their 2024 GMC AT4 2500 HD with a 6.6 Gas/10spd Allison achieved around 20 mpg when not towing, with all freeway miles from Orange County, CA, to Goodyear, AZ, and back. When towing a trailer weighing approximately 5000 lbs, the fuel economy drops to 12-14 mpg. Additionally, they report that their 2018 Silverado 2500 HD Z71 Duramax achieved 17-19 mpg for their commute to work and 15-17 mpg just around town.
Another user on the same forum mentions that their 2024 Chevy 2500 gets 13 mpg in the city, 15 mpg on the highway, and 9 mpg when towing. They express disappointment with these numbers, as other users have reported achieving 19-22 mpg with similar vehicles. However, it's important to note that fuel economy can be influenced by various factors, including driving style and terrain.
A 2024 Chevy Silverado ZR2 Duramax Diesel review by Motortrend reports an impressive best tank of 34 mpg with 826 miles of range. Over eight months and 16,000 miles of diverse driving, the vehicle averaged 18.8 mpg, exceeding its EPA combined fuel economy rating of 20 mpg.
While these figures provide a range of fuel economy estimates for the 2024 Chevy Duramax, it's important to remember that real-world fuel economy can vary significantly depending on various factors, including driving habits, terrain, vehicle maintenance, and the weight of any towed loads.
Additionally, when considering the fuel economy of a vehicle like the Chevy Duramax, it's worth noting that diesel engines typically offer better fuel efficiency than their gasoline counterparts, especially when towing or hauling heavy loads. However, diesel engines may also come with higher maintenance costs, which can impact the overall cost of ownership.

Fuel economy of a 2004 Chevy Duramax
The fuel economy of a 2004 Chevy Duramax depends on a variety of factors, including the model, engine type, driving conditions, and individual driving habits.
The Chevy Silverado 2500HD LS 6.6 with the Duramax diesel engine is a popular choice for those seeking good fuel economy. One owner reported achieving 17.2 mpg after their first tank of fuel and 15.2 mpg on their second tank, with an overall average of 18-19 mpg in both city and highway driving. Another owner of the same model reported fuel economy figures ranging from 17 to 19 mpg with 2500 miles on the odometer. These figures are consistent with other owners' experiences, with some reporting fuel economy of around 18 mpg on the highway.
The Duramax engine also offers improved horsepower and torque compared to previous models. The LLY engine, released in the second half of 2004, boasts approximately 320 hp and 590 lb-ft of torque. This increase in power and torque, however, may result in slightly lower fuel economy compared to older models.
Additionally, driving conditions and habits can significantly impact fuel economy. For example, driving at higher speeds, such as 75-80 mph, can decrease fuel efficiency to around 16 mpg. In contrast, driving at lower speeds, such as 55-60 mph, can improve fuel economy to 18-19 mpg or even higher. Towing or hauling heavy loads will also reduce fuel economy, with some owners reporting figures as low as 10-12 mpg while towing.
Overall, the 2004 Chevy Duramax offers reasonable fuel economy, especially when considering the vehicle's weight and performance capabilities. While some owners report figures above 18 mpg, others fall short of this mark, highlighting the variability in real-world fuel efficiency depending on various factors.
