Wrong.
+2 even Pablo, the Amsoil guy on this forum, will tell you that the Group 4 or 5 vs Group 3 is irrelevant. Mobil could not call their oil fully synthetic in the US if legally it wasn't. Don't believe the FUD.
The Mobil/Castrol thing was never a case AT LAW. There is no "legal" aspect.
Groups are irrelevant in all but the most seldom cases where some condition creates a requirement for it. Even aspects such as oxidation resistance, which WAS a big consideration or syn vs conventional, are more or less moot with grp III/III+.
With higher prices come higher profits at similar markups. Some "educated" folks get a feelgood that really does nothing, and boutique blenders sell PAO to them for 3k OCIs as if the vehicle owners are doing themselves a favor.
