What to Look for Before Buying?

Now that all that is out of the way, you may still be a bit perplexed. No need to worry, we know just what you need.

There are some things that you will need to consider before making a purchase, and in this short buying guide, that is exactly what we will be telling you about.

Correct Type of Oil

First, you need to choose the correct oil for your vehicle. The grades of motor oils depend on the SAE.

Oils are graded using numbers that range between 0 and 60 that determines the viscosity of the oil.

Here, the higher the number, the thicker the oil. For example, an oil that has an SAE of 5W-30 grade will thicken less in colder temperatures that one with a 10W-30 grade or something similar.


The type of Royal Purple oil you are going to go for depends on the total mileage of your car.

If your vehicle has a mileage over 100000 miles, you may want to go for the HMX high mileage oil.

It has been specially formulated to resist wear and corrosion while also keeping the engine clean.

Performance Needs

If you are someone who is into fast and rough driving, you may want to look for something specially designed to deal with increased engine heat and wear.

However, for any marine racers, something tough would be a good choice; for example, the manufacturer’s XPR oil.

Additive Technologies

These are created by the manufacturers themselves and really give them an advantage against their competitors.

All of them are good, and they greatly enhance the performance of your car. Synerlec is one of these technologies, as mentioned in the review.
