SuperTech full syn is currently dexos1 Gen2 qualified, and I doubt anyone would have an issue with it either. Thats about where RP is performance-wise.
Thing is, SuperTech is about $3.50/qt in 5-quart jugs, and its decent stuff.
If you want "boutique" with likely better performance, then go for a German full-synthetic with tungsten, tri-nuke moly, and esters in a majority PAO formula: Ravenol dexos1 Gen2 oil. At least then you pay more and may indeed be getting a benefit.
Or, alternatively, use Mobil1 Annual Protection regardless of it's extra cost, as it is the latest chemistry from Exxon-Mobil scientists and has a very low NOACK to indicate its quite good.
