An engine runs a car, but what runs the engine?
Chrysler Hemi engines are more commonly known by their trademark “Hemi” and are a part of the American V8 and I6 gasoline engines. They contain overhead valve hemispherical combustion chambers, and Chrysler has designed three different engines for automobiles.
Moving on, for at least a bunch of decades, Hemi has been considered one of the top engines in the market. However, it isn’t free of issues and needs constant maintenance. One of the factors that must be given special attention to is using top-grade oil with the 5.7 Hemi.
So, if you’re looking for the best oil for 5.7 Hemi, then I’ve got you covered with my guide. Thus, without further ado, let’s dive in and check the different options out!
Best Oil For 5.7 Hemi
1. Castrol 03063
Coming in first on our list is the 03063 by Castrol, a brand that is known for making quality products. It is one of the top-ranked engine oils and is available in a five-quart pack.
Product Highlights
To begin with, the Castrol 03063 does a great job of protecting the engine from wear and tear. It doesn’t contain any artificial constituents and is ultra-clean. In addition to this, the oil isn’t too viscous and, thus, is able to flow through the engine smoothly.
This is especially an added advantage for people living in colder climates since oils tend to freeze up in such places.
To this effect, the oil passes through the engine quite speedily and thereby doesn’t create much friction in the process. This, in turn, leads to a noticeable increase in mileage.
Yet another impressive highlight of this oil is the TriShield technology, which helps to obliterate any deposits in the pipeline. These deposits are responsible for restricting the flow of oil, which in turn leads to decreased capability and performance.
What’s There To Like About It
One thing I liked about this oil was that it is certified by the International Lubricant Standardization and Approval Committee, as well as the American Petroleum Institute. This means that it has met all safety regulations and performance standards and is thus, reliable.
I also liked how utilizing this oil qualifies one for the Castrol engine warranty. The warranty covers a distance of up to 500,000 miles, and one can easily register for it online.
What’s There Not To Like About It
I really liked the performance of this product, which is why I was quite disappointed by its packaging and shipping. The first order I placed came soaking wet and drenched in oil. Needless to say, I couldn’t use it.
I ended up having to place another order, and thankfully the subsequent delivery was made without any shipping errors.

Buyers Guide
The right oil minimizes friction to prevent premature wear. At the same time, it has lubricating benefits to optimize performance sans the noise. Not all oils, however, can deliver the same effects. With this in mind, let’s take a look at some of the factors to be kept in mind while buying the best oil for the 5.7 Hemi.
1. Type Of Oil To Be Used: Conventional Vs. Synthetic
Conventional or mineral oil was the traditional choice for protecting engines; however, it’s pretty uncommon to see it being used now. This kind of oil is made by refining crude oil that has been extracted from the ground.
The refining process of crude is quite easy and cheap, which is why conventional oil is also quite cheap. However, this is virtually the only benefit of this oil.
The biggest flaw of conventional oil is that it's chemically unstable. This is due to the fact that it has been refined from crude oil, which leads to it having impurities at the molecular level. Moreover, it tends to acidify and oxidize really fast.
Moving on, synthetic motor oil is treated chemically at a plant, and thus, it has very few impurities. This translates to superior performance and better protection of the engine; in fact, synthetic oil provides ten times more protection against oxidation.
You’ll notice that all the products on our list are synthetic oils because, despite their higher price, they are undoubtedly superior. Their higher rate is also justified since they undergo a grueling refining process.
The 5.7 Hemi can work with conventional oils, too, but its performance will be subpar when compared to synthetic oil. Hence, since all the oils on our list are synthetic, feel free to pick any of them.
2. Viscosity Of The Oil
The viscosity of the oil is integral for a well-functioning engine since using an oil that is thicker or thinner than the recommended consistency can destroy it over time.
There is a widespread misconception that using oil with more thickness is a good idea since that might quieten down what is known as the “Hemi tick.” However, this is just a myth since, in reality, thicker oil is harder to pump and slow to flow through the engine.
In addition to that, it creates too much friction and cannot transfer heat properly, which might lead to the formation of sludge deposits in the engine as well as overheating.
The viscosity required by the 5.7 Hemi depends from vehicle to vehicle, and the correct specification can be found in the owner’s manual of the car. However, the Pennzoil 550045195 has low viscosity and is, thus, a great pick in general.
3. Adherence to Oil API Standards
The 5.7 Hemi is manufactured by Chrysler, and the brand has put in place certain requirements for engine oils to meet. Not only do they have to be API certified, but they must also meet the requirements of Chrysler Material Standard MS-6395.
The above-mentioned requirements of Chrysler Material Standard MS-6395 are really tough to adhere to, and only super high-quality oils can meet them. And in general, motor oils that meet these standards help the engine run more quietly and smoothly.
In addition to that, meeting API standards is imperative, too, since that is a good indication of the quality of the soil. The API SP, in particular, is a new addition to the API standards, and oils that are in accordance with it can provide protection from LSPI or Low-Speed Pre Ignition.
Apart from that, API SP compatible motor oils also have better high-temperature deposit protection, enhanced insulation from chain wear, and stricter varnish and sludge control. The Mobil 112078 is API SP compliant and, thus, an ideal choice.
Frequently Asked Questions (FAQs)
The pressure of the oil should ideally range between 25 to 65 psi, and this is usually the standard requirement for warm oil. However, the weight of the truck should also be taken into account.
Yes, they really do. They can last for 250000 to 300000 miles. However, regular maintenance must be done, and the best quality motor oil must be used with them to achieve these numbers.
I recommend keeping an oil drain pan, oil filter remover, a socket, a rag, and a torque wrench handy for adding oil to the 5.7 Hemi. Follow the following steps to change it:
Step 1
Place a pan below the engine and use it to drain the oil. Thereafter, unlock the drain plug.
Step 2
Extract the oil filter after screwing back the plug. Then add fresh oil to the new filter after removing the old one.
Step 3
Clean the plug and the filter. Finally, start the engine after checking the engine oil level.
My Final Recommendation
Before I tell you my final recommendation, I must mention one thing. Don’t use any oil flush products or oil additives in your motor oil because they do more harm than good in most cases.
Unless you’re an engine oil expert, adding extra additives will mess up the chemical formulation of the oil. This is because all good synthetic motor oils already have additives, and adding more can cause issues in the long run.
Now, it’s time for me to pick the winners. My top recommendation would be the Castrol 03063 because of its excellent brand value and performance. A close second would be the Valvoline 787023 due to its top-notch functionality and value for money.
With this, I’ve reached the end of my guide, and I hope to see you again soon!
