    So I know the only readily available full synthetic off the shelves is the 0W30 Castrol (German Car Formula).

    There's also Redline and Amsoil.
    What about using LAT based oils?(that stuff is in there forever) even if you change the oil on next R&R you can see it draining out.
    Any advantages to using real synthetic fluid?- Has anyone sent their oil to blackstone?
    Since the OEM Toyota 0W20 isn't full synthetic as far as I know??-

    Seriously, have you tried to search?

    What is LAT?

    Toyota 0W-20 is a full synthetic oil, whether made by Nippon (originally) or Mobil (currently.)

    "LAT based oil" sounds like LAT is a type of base oil. Apparently it isn't and you misspoke.

    Is Toyota 0W-20 SN made in heaven? - Bob Is The Oil Guy
    They're saying Subaru is the closest to GF5, and those that are into rotaries or high power high strung engines know that LAT oils stick to metal like no other, even after a R&R with another fluid you can still tell LAT exists/or has existed in that engine.
