5.7 Hemi Engine Oil - Your Buying Guide

Choosing the right oil

The 5.7L engine installed in your Dodge pickup truck or Chrysler 300C vehicle has been designed with meticulous care for heavy-duty performance. If you’re using a brand new vehicle or looking to change the oil in your existing car, you’ll have to feed the engine with the best engine oil for 5.7 hemi vehicles. The task of selecting the right oil type for your vehicle could turn out to be daunting, as so many options are available.

Though the availability of engine oil alternatives could overwhelm you, there’s a simple way out of the quagmire: refer to your vehicle’s manual. For a start, the owner’s manual will mention the weight of oil. Buy branded motor oil having the recommended or prescribed weight featuring the starburst logo, which certifies that the same has been approved by API (American Petroleum Institute).

Identifying with and appreciating the labels

Before you decide on the best engine oil for 5.7 Hemi motors, read the fine print on the container. You’ll see this labeling on every container of established and reputed engine oil brands. You’ll find two labels on the container-the the API donut and the Starburst pictogram tags.

The API donut indicates if the engine oil fulfills the current or the latest SL service evaluations or ratings. If you spot a “C” mark, it signifies that the motor oil has been tested for use with diesel engines. The donut mentions the ‘Society of Automotive Engineers’ (SAE 5W-30 or 10W-40) viscosity number, indicating that the oil has cleared the Energy Conservation assessment.

Understanding Viscosity

Viscosity is another crucial factor that you should take into consideration before choosing a motor oil brand for your Hemi 5.7L. You’ll see an alphanumeric number like 5W-30 or 10W-40; the first number (5 or 10) is the rating in Fahrenheit followed by W, which stands for ‘winter’ and the second number (30 or 40) represents the oil’s resistivity rating.

Any oil or lubricant thins if it is heated and becomes denser or thickens on cooling. Blending the engine oil with the appropriate additives enables it to resist thinning in high temperatures and becoming overly viscous when it’s cold.

Should You Go for Conventional Oil or Full Synthetic Oil?

There are four different types of motor oil for 5.7 hemi available in the automotive market: conventional oil, full synthetic oil, synthetic blend oil, and high-mileage oil.

You should check with your vehicle’s guidebook and read the instructions outlined by the manufacturer for getting an idea as to the type of oil that’ll work with your vehicle’s engine. Other factors that will influence your choice of motor oil include the vehicle’s make and model, its age, the climate in your area, and your driving habits.

Frequently Asked Questions

What is so Unique About the Generation III Engine?

Chrysler pioneered the engine design with a hemispherical-styled internal combustion chamber in the 1950s. The Gen III Hemi 5.7 engine was the latest in the line of hemispherical engines that was launched by Chrysler in 2003.  The 3rd generation of the engine with a 345 horsepower rating was designed for Dodge Ram pickup trucks.

This 3rd gen Hemi is available in four distinct cubic-inch displacements of 392, 376, 370, and 345 but are prevalent in their metric correspondents: 6.4L, 6.2L, 6.1L, and 5.7L. Though not hemispherical as the previous two generations of Hemi engines, the design was retained in the 3rd generation for integrating big ports and valves. The structure comes with a coil-on-plug ignition system with two spark plugs for each cylinder to reduce the distance the flame has to cover, resulting in better combustion and decreased emissions.   

What Purpose Does Engine Oil Serve?

Engine oil is indispensable for lubricating the components of the engine and keeping the engine cool so that the car can run efficiently. The motor oil lubricates the exhaust valves that become hot. A periodic oil change is necessary to prevent the accumulation of sludge and dirt that could damage the engine.

Which Type of Engine Oil Should you use for Hemi 5.7?

You should check with your vehicle’s manual and go through the manufacturer’s recommendations for understanding the engine oil type your Hemi 5.7 needs.

Are Full Synthetic Oils Expensive?

Full synthetic engine oils are expensive. But if you take the mileage (which you get from synthetic oil) into account before it is time for an oil change, it works out cheaper than conventional or synthetic blend oils.


In this best oil for 5.7 Hemi review, we assessed six high-quality motor oil brands: Liqui Moly, Royal Purple, Pennzoil Ultra Premium, Dodge Ram, Mopar, and Blau.  Liqui Moly, Royal Purple, and Pennzoil Ultra are affordable despite being full synthetic engine oils.  Blau and Dodge RAM are compatible for use with heavy-duty and high-performance vehicles outfitted with 5.7L Hemi engines.
