Why Compare?

Motor oil is an undeniably essential element for the health of an automobile. There are numerous motor oils available in the market. There are many types of quality and brands of motor oils for different types of automobiles. So if you go to the market searching for suitable motor oil for your automobile, you might get confused. So it is necessary to have proper knowledge about the differences and similarities among different motor oils. Here you will get a thorough idea about the two famous motor oils- Redline and Royal Purple. 

Change Interval:

The annual replacement cost is different from traditional oils that must be replaced every 5,000 to 7,500 miles. Synthetic oils have a longer service life. Redline requires 18,000 miles and Royal Purple recommends 12,000 miles. The money you spend on car oil depends on how often you change the car oil and how many miles you have to travel with the oil you choose. 

Therefore, if you use Royal Purple, you will spend more money on oil changes than Redline. Therefore, Redline is the clear winner of this round of competition.

Usability: 

Although synthetic oil has a longer service life, it is generally more expensive than ordinary oil. When comparing prices per liter, Royal Purple is cheaper than the redline. So, Royal Purple is a budget-friendly option. 

Total base number: 

The TBN test measures a lubricant’s reserve alkalinity, which adjusts the level of acidity produced in the engine during combustion. As we all know, high TBN engine oil will reduce some of the acid corrosion effects. Redline has a higher content than Royal Purple. This makes Amsoil the superior product. 

Cold start viscosity test:

Engine oil thickness at high or low temperature is directly related to engine start at low temperature. It shows a more leisurely cold start and reduces battery consumption. Also, Royal Purple (6300) gives a better result than Redline (6400).

Nock Volatility Test: 

This test shows the evaporation loss of engine oil at high temperatures. For modern heat engines, this is a valuable test. During the test, the oil was exposed to heat and air to determine how much weight was lost compared to the original weight before heating. Redline’s weight loss effect is less than Royal Purple, making Redline the superior motor oil in this regard.

Oxidation: 

This test can measure the deposits formed in engine oil at high temperatures. Lubricants tend to accumulate deposits when heated, which reduces overall efficiency and productivity. With the increase in turbocharging and direct injection, it is important to keep deposits on the engine as low as possible. In this test, Royal Purple has a lower rank than Redline. Therefore, Royal Purple is the winner here. 

Redline: 

  • Superior oxidation resistance.
  • Provides better acceleration and lower noise levels.
  • High natural viscosity.
  • Ester formula guarantees long-lasting engine protection.
  • High detergency reduces friction.
  • Expensive.
  • Comparatively low durability.

Royal Purple:

  • Oil efficiency.
  • Gives protection against corrosion caused by acids.
  • Compatible with the most motor vehicle running on ethanol.
  • Enhance engine protection.
  • Protects both gasoline and diesel engines.
  • Expensive.
  • Packaging causes leaks sometimes.

What factors should you consider when deciding the synthetic oil to use?

In contrast to traditional oils, synthetic oils are artificially formulated. As such, they meet the precise wishes of your engine. They include components that include thermal residences and cleansing agents. These decorate the overall performance and safety of your engine. However, all synthetic oils are not the same, and they arrive with exceptional specifications.

Is Royal Purple suitable for daily driving?

Royal Purple HPS oil is very suitable for gasoline and diesel engines. They are unlicensed road performance oils and may not fully meet the warranty requirements of new OEM vehicles because the price of cars is much higher.

Summary: 

Redline and Royal Purple are potential and competing motor oils and their features are also different from each other. You should know about the details of both of them before buying one.
