Review on Royal Purple 341777 Extended Filter by Mike Johnston

If I can do it myself, I will. disliked by other people working on my car. I did a little research to learn more about premium synthetic oil manufacturers. That's how I discovered Royal Purple. I bought six liters of their 5w-30 oil and needed a proper filter. I read about the characteristics of their filters and knew it would be silly to fit a cheap fram filter. In conclusion, I am completely satisfied with my experience with Royal Purple products and will continue to use them in the future. I love that their products are purple even though it's only cosmetic.
