Overview of Features

Royal Purple Features

For this review, we’re going to talk about Royal Purple 5W-30 engine oil, which is designed for gasoline engines.

It’s a fully synthetic high-performance motor oil, which means the formula helps improve the overall performance of your car’s engine. It also provides better wear protection than conventional and even synthetic blends. With more corrosion prevention, it helps improve engine horsepower and torque as well.

Keeping in mind the latest restrictions on car emissions, the company has specifically made this formula for protecting the catalytic emission system found on almost all modern vehicles. This is because of the proprietary additives they add to the synthetic oil base.

Royal Purple is a premium motor oil brand. In other words, it’s more on the pricier end of the spectrum. So you can expect nothing but quality, as evidenced by online reviews, too.

Another feature is its low coefficient of friction, which ultimately results in better fuel economy. This makes it ideal for those vehicles that do a lot of stop-and-go driving. They go so far as to say that it meets the same fuel economy like that of 5W-20 oils.

You can also use it with ethanol fuels as the patented additives prevent sludge that’s more common with such fuels. Moreover, it shows no rusting in standard industrial tests for different car markets, including North America and Europe.

Since the oil weight is 5W-30, it provides a smooth cold start in frigid winters. It also has a high operating temperature threshold. So this is essentially an all-weather oil.

This Royal Purple 5W30 engine oil comes in both single quart and five-quart containers.

What Customers Say

Customers have a love-hate attitude towards Royal Purple products in general. Those who use it vouch for its efficacy, especially in improving engine performance. However, others think it’s just a really expensive motor oil with a purple dye.

One customer posted results from the PQIA test data for the Royal Purple 5W-30 High-Performance on one forum, and it passed all the standard tests. However, in one video where it was tested against Amsoil’s 5W-30 synthetic oil, it lost some tests by a very narrow margin.

Should I Switch to Royal Purple Motor Oil?

It’s clear that Royal Purple oil exceeds many industry standards and is a premium-quality oil. However, that premium quality comes at a premium price. While you’ll most likely see performance and fuel economy improvement, you’ll end up paying a lot more for maintenance over the long term.

If you own an expensive car that generally has high repair costs and plan on keeping it for a long time, it may make sense to move to Royal Purple.

Before you decide to switch, make sure to see that it meets your car’s engine oil requirements set out by the manufacturer, especially the oil weight.
