Is a 5.7 Hemi good on gas?
The 5.7 Hemi engine, known for its power and performance, is a popular choice among truck and muscle car enthusiasts. However, when it comes to fuel efficiency, many potential buyers wonder if this engine is a good option for their daily driving needs. In this article, we will explore the fuel economy of the 5.7 Hemi, its performance characteristics, and what factors can influence its gas mileage.
Understanding the 5.7 Hemi Engine
The 5.7 Hemi is a V8 engine produced by Chrysler, featuring a unique hemispherical combustion chamber design that enhances airflow and combustion efficiency. This engine is commonly found in vehicles like the Dodge Ram, Chrysler 300, and Jeep Grand Cherokee. While it delivers impressive horsepower and torque, its fuel efficiency can vary significantly based on several factors.
Fuel Economy Ratings
When considering whether the 5.7 Hemi is good on gas, it's essential to look at its fuel economy ratings. Generally, the 5.7 Hemi engine achieves:
- Approximately 15-20 miles per gallon (mpg) in the city.
- Approximately 20-25 mpg on the highway.
These figures can vary based on the specific vehicle model, driving conditions, and driving habits. For instance, trucks tend to have lower fuel efficiency compared to sedans due to their weight and aerodynamics.
Factors Affecting Fuel Efficiency
Several factors can influence the gas mileage of a 5.7 Hemi engine:
- Driving Habits: Aggressive driving, rapid acceleration, and high speeds can significantly reduce fuel efficiency.
- Vehicle Weight: Heavier vehicles will consume more fuel, so the type of vehicle equipped with the 5.7 Hemi matters.
- Maintenance: Regular maintenance, including oil changes and air filter replacements, can help maintain optimal fuel efficiency.
- Terrain: Driving in hilly or mountainous areas can lead to increased fuel consumption compared to flat terrains.
Conclusion
In summary, while the 5.7 Hemi engine is not the most fuel-efficient option available, it offers a balance of power and performance that many drivers appreciate. If you prioritize horsepower and towing capacity over fuel economy, the 5.7 Hemi may be a suitable choice for you. However, if gas mileage is your primary concern, you might want to consider smaller engines or hybrid options. Ultimately, understanding your driving needs and habits will help you make the best decision regarding the 5.7 Hemi engine.

Does the 5.7 Hemi get good gas mileage?
5.7 Hemi 4x4 crew cab non-eTorque and I get an overall average of 16.7 mpg, 20ish going 75 on the highway.
Do Hemi engines use more gas?
However, EPA estimates indicate the HEMI engines haven't done all too badly in terms of fuel efficiency. For instance, a 2024 RAM 1500 with rear-wheel drive and the 5.7-liter HEMI engine returns an EPA-estimated 18 mpg in the city, 23 mpg on the highway, and 20 mpg combined.
How many miles will a 5.7 Hemi last?
Hemis are awesome engines... You could easily have another 150k miles if it was well maintained. Even after that a rebuild will not be too costly and you good for another possible decade+ of usage.
Is the 5.7 HEMI a strong engine?
The 5.7 Hemi is a popular V8 engine that is used in many vehicles manufactured by Dodge and Chrysler. The 5.7 Hemi is known for its impressive power and torque output, and for the 2021 model year, it has an output of up to 395 horsepower and 410 lb-ft of torque.
What years to avoid for the 5.7 HEMI Ram 1500?
Q: What are the Dodge RAM 1500 years to avoid? A: The Dodge RAM 1500 years to avoid are 2003, 2010-2013 (specifically models with the 5.7-liter V8 engine), 2014, 2015, and 2016. These model years have had various problems and recalls related to the engine, transmission, suspension, and electrical systems.
Does a 5.7 Hemi need premium gas?
Dodge Charger R/T
Turns out it's also for owners of Fiat Chrysler's Hemi 5.7-liter V-8, as the company recommends 89-octane fuel for this engine.
How much horsepower does a 5.7 Hemi have?
395 horsepower
The 5.7 Hemi is known for its impressive power and torque output, and for the 2021 model year, it has an output of up to 395 horsepower and 410 lb-ft of torque.
Why is the 5.7 HEMI so good?
The Hemi engine's design can provide more power compared to a conventional engine because it allows higher compression ratios and facilitates better air-fuel mixtures inside the cylinder. This allows the engine to ignite all the fuel inside the cylinder, resulting in more heat and more energy.
How to improve 5.7 HEMI gas mileage?
The easiest way to do this is by driving at a moderate pace, but adjusting your vehicle can also help. For instance, a roof rack or an uncovered bed can increase the aerodynamic drag. Removing such accessories and getting a bed cover can significantly affect your fuel efficiency.
Does premium gas get better mileage?
No, any fuel efficiency gained using premium fuel would stem from engine performance, not the gas itself. Buying premium gas won't have you visiting a gas station any less frequently, especially with a standard engine not designed to take advantage of premium gas.
