Royal Purple or Castrol Edge?
Both Royal Purple and Castrol produce some of the best motor oils in their own specific categories.
However, if we were to compare both, then we could break each down into multiple factors to get a better understanding between the two.
The most crucial factor is the material that goes into each product as that determines the quality of the oil.
For Royal Purple, you’ll be getting a combination of premium base oils and the company’s proprietary blends of compounds.
This blend produces an overall right quality product that mixes well into any vehicle type.
However, the case is not the same for Castrol; these people, on the other hand, have their own additional items added into the mixture.
Castrol uses the same blend of oils needed to formulate the motor oil, but they also add fluid titanium in their Edge Series
Fluid titanium can produce the most durable coatings than any motor oil brand available in the market.
The titanium improves your experience to a much higher extent making the Castrol a step better in this case.
On the pricing end, however, Royal Purple seems to tip the scales. Being a brand based mainly in the US, the company has fewer costs to bare and can charge a much lower price on its products. For Castrol, the prices are a bit on the high-end scale.
As mentioned before, both products cater to a different class of people; thus, both accordingly provide the best buy.
However, this Royal Purple vs. Castrol debate should help you understand how important it is to know which category you and your car belong to.
As the right purchase could help improve the performance both effectively and efficiently.
