Yes Royal Purple filters are spun micro glass, they will out last your oil for sure, I've cut them open after 14 months, still pliable. I would check out walmart penzoil synthetics, jugs are great value. Dont get the walmart synthetic, no moly for sure. Also, M1 costco deal I believe is still going and continues to be the best deal in oil. If you get hemi tick, plug into syn thread. 7 quarts for the hemi. Just make sure you get an oil with moly in it, you can look at the list here, and scroll down to molybdenum. I like 5w30 as well.
