Royal Purple vs. Amsoil:  5 Oil Test Difference

You might think that oil is the same across the board, but you’d be wrong. There are many differences between companies that produce oil, and some of them can have a huge impact on your engine.

So which one should you choose? To figure out which oil you should use in your car, look at how Royal purple and Amsoil differ in these five tests.

Royal Purple vs. Amsoil

  • Four-Ball Wear Test: This test is used to assess the wear scar characteristics and coefficient of friction of lubricant oil, where the smaller the wear scar, the better the lubricant prevents wear.

Amsoil comes out on top with scar wear that is approximately 0.50 mm, while Royal Purple has a value that is very near to 1.40mm.

 

  • \NOACK Instability Test: It is a commonly used standard test for evaluating lubricant evaporation loss, and engine oils must have a low evaporation rate for quality and environmental reasons.

According to the API SM motor oil standard, the maximum percent volatilization rate should be less than 15%; Amsoil has less than 8%, while Royal Purple has less than 10%.

  • TEOST Test:  This test mimics the influence of engine running circumstances on the oxidation and deposit-forming tendencies of engine oils, particularly in the high-temperature Turbocharger region. Still, Amazon emerges on top with a total deposit weight of 7.0 mg, whereas Royal Purple has 25.4 mg.

  • Base Number Test: Measuring the Base Number (BN) can assist verify that the oil can protect the component from acid corrosion; it is greatest when it is new and diminishes as it is used. Amsoil has a greater BN of fewer than 14 units in this test, while Royal Purple only has less than 9.

  • Cold Cranking Viscosity Test: Cold-cranking viscosity (CCS) is used to describe oil viscosity in crankshaft bearings during cold temperature startup. Amsoil has a better result with the lowest viscosity at -30°C, less than 4000, while Royal Purple has a higher viscosity, greater than 6000.

FAQs

Is Royal Purple worth the money?

The expense of Royal Purple synthetic oil is well worth it. It is more costly than its counterparts because of the extensive research into developing it with a longer drain duration and resistance to oxidation and corrosion properties.

This synthetic oil contains cleaning qualities that aid in preventing deposits and keeps sludge from forming. It is also temperature resistant and does not evaporate in high temperatures, allowing your engine to have the essential lubrication.

What are the things to consider in choosing motor oil?

When choosing a motor oil, specifically a synthetic one, consider the pricing since a high price does not necessarily suggest the highest quality. Strive for the highest possible quality at the lowest possible price so that you can save a substantial amount of money.

Next, examine the thermal properties of the synthetic oil to ensure that it will not deteriorate at high temperatures. As a result, you’ll have better engine protection and longer oil drain intervals.

The viscosity of synthetic oil is also important to consider since it affects how it flows in the engine. It also influences how effectively the oil lubricates your engine when it starts.

Lastly, it should also be able to maintain your engine clean and healthy. As the oil flows through the engine, it should remove any deposits and keep sludge formation.

Do Amsoil provide better protection under extreme temperatures?

One advantage of using synthetic oils is using them at low temperatures, improving oil flow and lubrication during start-ups. Thermal characteristics are included in both Amsoil and Royal Purple synthetic oils.

But, Amsoil synthetic oil outperforms Royal Purple because its viscosity is rather high, enabling easy pumping at low temperatures. As a result, it lubricates the moving parts, reducing wear and tear.

More so, the oil does not evaporate at high temperatures and burns off, allowing longer oil drain intervals and saving money. It also protects your engine from oxidation and acid development, resulting in no corrosion of engine parts, extending its lifespan.

Is Amsoil good for high mileage cars?

Amsoil Premium Protection Motor Oil is high mileage, multi-functional, and protects against wear. Ideal for situations requiring the added protection of a higher-viscosity oil.

Also, it is ideal for older vehicles with heavy mileage and a high level of sludge. Amsoil XL Series detergents are designed for engines with more wear and carbon buildup with 25% more cleaning power to keep your engine running smoother.

Final Thoughts

If you’re a car enthusiast, you should look for the finest engine oil for your vehicle. It is reasonable to claim that in the Amsoil vs. Royal Purple discussion, they both pass engine oil testing.
