The 6.4 Hemi engine is a powerful and popular engine found in many Dodge and Jeep vehicles. While the engine provides impressive performance, it can also be a gas guzzler, especially if driven aggressively. However, with a few simple tips and tricks, you can improve the gas mileage of your 6.4 Hemi without sacrificing performance.
Use Premium Fuel
The 6.4 Hemi engine is designed to run on premium fuel, which has a higher octane rating than regular gasoline. Premium fuel provides better combustion, which can result in better fuel efficiency and improved performance. While premium fuel is more expensive than regular gasoline, the improved gas mileage and performance can offset the additional cost.
Keep Your Tires Inflated
Proper tire inflation can improve gas mileage by reducing rolling resistance. Underinflated tires can increase fuel consumption and decrease performance. Check your tire pressure regularly and inflate your tires to the recommended pressure listed in your vehicle’s owner’s manual.
Replace Your Air Filter
A dirty air filter can reduce airflow to the engine, which can decrease performance and fuel efficiency. Replace your air filter at least once a year or more often if you drive in dusty or dirty conditions. A clean air filter can improve gas mileage by up to 10%.
Reduce Aerodynamic Drag
Aerodynamic drag can decrease fuel efficiency, especially at high speeds. Remove any roof racks or other accessories that may increase wind resistance. Also, keep your windows closed when driving at high speeds to reduce drag.
Use Cruise Control
Using cruise control can help you maintain a consistent speed and reduce fuel consumption. It can also reduce driver fatigue on long trips. Use cruise control whenever possible, especially on highways or other long stretches of road.
Avoid Aggressive Driving
Aggressive driving, such as rapid acceleration and hard braking, can significantly reduce gas mileage. Accelerate and brake smoothly and avoid rapid changes in speed. Also, try to anticipate traffic flow and adjust your speed accordingly to reduce unnecessary acceleration and braking.
Consider a Tuning Solution
A tuning solution such as a performance tuner can optimize the engine’s settings for improved gas mileage and performance. These devices can adjust various engine parameters such as fuel injection timing and throttle response to provide better fuel efficiency and increased horsepower.
How many miles per gallon does a 6.4 Hemi Ram get?
The fuel economy of a 6.4 Hemi Ram can vary depending on the driving conditions and the specific model of the vehicle. However, on average, a 6.4 Hemi Ram can get around 13-17 miles per gallon in the city and 18-22 miles per gallon on the highway.
How can I improve my Hemi gas mileage?
You can improve your Hemi gas mileage by using premium fuel, keeping your tires inflated, replacing your air filter, reducing aerodynamic drag, using cruise control, avoiding aggressive driving, and considering a tuning solution.
What fuel is recommended for a 6.4 Hemi?
The 6.4 Hemi engine is designed to run on premium fuel, which has a higher octane rating than regular gasoline. Premium fuel provides better combustion, which can result in better fuel efficiency and improved performance.
Conclusion
Improving gas mileage on a 6.4 Hemi engine can be challenging, but it’s not impossible. Using premium fuel, keeping your tires inflated, replacing your air filter, reducing aerodynamic drag, using cruise control, avoiding aggressive driving, and considering a tuning solution are all effective ways to improve gas mileage without sacrificing performance. With these tips, you can enjoy the power and performance of your 6.4 Hemi engine while also saving money on gas.
