Review: The best oil on the market. Recommend anybody to make the switch, particularly if your car is still under 100,000 km though I did switch my 2008 Kia Sportage at 150,000 km with no problem. It really cleaned the engine too and subsequent oil changes had cleaner oil coming out!

## Questions & Answers

**Q: I have seen Royal Purple oil being used in race engines for years....what makes Royal Purple Full Synthetic better than say.. Mobil1 Full Synthetic?**
A: Royal One is considered one of the better synthetic oils. Notice it does not say 100% synthetic.  Only if they say 100% are they completely free of any petroleum based oil. Also note sticker says approved by Petroleum standards. Mobil 1 says this too. A 100% synthetic oil requires no additives. In Europe, fully synthetic = 100% synthetic. In the United States it doesn't.

**Q: Is this oil ok to use in my supercharged fr-s using e85 fuel? i change my oil every 5k miles**
A: Looks like you keep up with maintenance, so yes, I think it would suit your needs. The first oil change with Royal Purple is a time in which the oil acclimates to its engine environment. You can still get 5000 miles out of it, but with the second oil change you will see a subtle change with oil life extending beyond the 5000 to 6000 or more. In my case, I am getting 10000 miles between oil changes, and the oil still has no burned smell to it. I do recommend using a good oil filter as well, like Wix, or something that can take the temperature ranges. If your engine is using oil, then I'd be cautious in making the switch, otherwise I have no regrets. With the last rebuild on my 1988 Jeep Wrangler I started it off with Royal Purple and haven't looked back. Engine runs smoother and I get the extended oil mileage.

**Q: Is this listing for 1 quart or 6 quarts?**
A: this is for 1 quart only

**Q: Does this work for the 2013 toyota prius v? i am looking for this with 75,000+ miles with royal purple hmx high mileage synthetic 0w-20 ilsac gf-5 mul**
A: I use it in my 2017 prius 2. It works great. Comes out looking damn near new after 10k miles. When i need to switch to high mileage oil, i will use HMX.
