Please don't put Royal Purple in the same category as Amsoil. Royal Purple's only redeeming feature is purple dye, compared to SuperTech for example. Amsoil is exceptional oil, not RP.
Thats basically smart. I've done that as well (Pennz Plat 0w20 in a '19 Tiguan now) because it had a $10 rebate and is dexos1, its decent. For that Tiguan, VW is adamant about raising the performance level (vw 508 nur blaugrünes öl) of their 0w20, so I'll happily do that in the future once that Platinum I had gets used for a partial-interval oil change at around 7k miles instead of VW's 10k miles with 508.
Most of the Extended Performance oils like Amsoil SS or M1 Annual or Castrol gold bottle or VW 508 oils are best used if oil change intervals are 10,000 miles (1 or 2 years or so max) with warmed-up trips.
It also depends on how much you value the engine. A new Veloster N poster is a perfect example. We discussed his choice of Castrol Edge black bottle, and said it was a good choice. Then I mentioned that racing or performance driving meant a little thicker oil could be valuable. He keeps that brand new Veloster spit-shined I'm sure, so he actually went for one of the best oils on the market: A racing oil with street cred, Ravenol REP 5w30, with semi-exotic base oils and additives from Germany. Its a cool oil, and maybe over-kill, but its a new car he's proud of, so there it is. No SuperTech (or RP!) for him.
