The Chrysler Hemispherical 5.7 engine popularly known as Hemi is a set of V8 and six-straight gasoline engines manufactured by Chrysler Corporation. The 5.7 hemi is so-called because of its hemisphere-shaped cylindrical head, which makes the combustion chamber more efficient, resulting in minimal heat loss.  Chrysler manufactured and marketed three distinct types or generations of Hemi-engines.

The 5.7L Hemi is the third-generation and the latest gasoline engine that Chrysler designed exclusively for the Dodge Ram 3500, 2500, and 1500 pickup trucks. Later on, the Hemi 5.7 was made available for other pickup truck models such as Chrysler 300C, Jeep Grand Cherokee, and Dodge Durango. If you own a pickup truck outfitted with a 5.7 Hemi engine, then you’d need the best oil for 5.7 hemi to enable the engine to perform smoothly for years.

So, which is the best oil for the Hemi 5.7 engine? In this review, we’ll explore six best 5.7 Hemi oil brands complete with a buying guide so that you can choose the one that best fits your needs.

Things to Consider Before You Buy the Best Engine Oil for Hemi 5.7 Engine


  • Choosing the Best Oil for 5.7 Hemi

The Hemi 5.7L engine installed in your Dodge pickup truck or Chrysler 300C vehicle has been designed with meticulous care for heavy-duty performance. So, 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 Hemi 5.7. However, the task of selecting the right oil type for your vehicle could turn out to be quite daunting, as so many options are available.

Though the availability of so many engine oil alternatives could overwhelm and puzzle 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. Hence, always 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 your Hemi 5.7, carefully read the fine print on the container. You’ll see this labeling on every container of established and reputed engine oil brands. Generally, 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, then 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 and so on) 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, where 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 when it is heated and becomes denser or thickens on cooling. Therefore, blending the engine oil with the appropriate additives enables it to resist thinning excessively in high temperatures as well as stand firm against becoming overly viscous when it’s too cold.

  • Should You Go for Conventional Oil or Full Synthetic Oil?

There are four different types of motor oil 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.

FAQs


  • What is so unique about the Generation III Hemi 5.7 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 Hemi 5.7 with a 345 horsepower rating was designed specifically 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 more prevalent in their metric correspondents: 6.4L, 6.2L, 6.1L, and 5.7L. Though not as 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 also comes with a coil-on-plug ignition system with two spark plugs for each cylinder to reduce the distance the flame has to cover, thus 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 also lubricates the exhaust valves that become exceedingly hot in due course. 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 carefully 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, apparently speaking. But if you take the mileage (which you get from synthetic oil) into account before it is time for an oil change, then it works out cheaper than conventional or synthetic blend oils.

Conclusion

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 remarkably affordable despite being full synthetic engine oils.  Blau and Dodge RAM are more compatible for use with heavy-duty and high-performance vehicles outfitted with 5.7L Hemi engines.
