A 5.7L Hemi is made to last. You can expect an engine of this size to last 300,000 miles or more. Many trucks are known for lasting a long time, and usually, this is the reason: Truck engines are always bigger than a sedan or mid-size vehicle because they expect them to do more off-road it or towing.

These engines last longer because they do not have to work as hard as smaller engines when driving down the road. When an engine does not work as hard, it does not get worn out as easily. You can expect engines of this size to give you plenty of miles.

Another factor to consider is what you will be doing with the vehicle. This will determine how long it lasts. As mentioned above, these vehicles are made for heavy lifting. If you do not plan to tow much or strain the engine with a lot of weight, then it will typically last longer. If this will be a work truck, it may not last as long as it would if it was only driven like any other vehicle.

Do Hemi Engines Run On Diesel or Unleaded?

Hemi engines currently run on regular unleaded gasoline. They are often compared to diesel vehicles because of their power and longevity. Most of the time, regular gasoline engines do not last as long as diesel engines. Plenty of vehicles with diesel engines are found to still be running after 400,000 miles. While these vehicles are more expensive, their lifespan tends to extend longer than vehicles with regular gasoline.

This, of course, is not the case for a 5.7 Hemi or other Hemi engines. These engines last much longer than traditional gas engines and rival diesel-powered vehicles. With Hemi technology catching up to diesel engines, you can expect these to continue to improve with time.

A 5.7 Hemi will get anywhere from 300 or 400 to 650 horsepower. That is a lot of power! The 5.7 Hemi is built as strong as possible with all this horsepower, so it can tackle the weighty tasks most people buy these trucks for. 

What Is Horsepower (And Is 650 A Lot)?

Horsepower is the measurement used to express a vehicle's ability to work. This translates to engine power and vehicle speed when it comes to vehicles. One horsepower unit is equal to 550 foot-pounds per second. If you have higher horsepower, then your vehicle will be able to accelerate quicker. The Hemi offers a lot of horsepower for a vehicle, but you have to remember what the engine has to pull.

While 650 horsepower is more than some supercars, a 5.7 Hemi truck will not be beating any supercars in a drag race. The horsepower in a 5.7 Hemi is there to pull a heavy truck effectively while towing even heavier objects. The body of most Hemi engines is built to be tough rather than fast, although some sports cars have the same engines inside of them.

Do specific research on the type of vehicle you have and take it to a professional to avoid any mistakes.
