The new standards may kill off Group I passenger car oils. Group II may be the new baseline, but that does not mean synthetics will take over any time soon, they are still too expensive.
Solvent refining (Group I) replaced straight distallation decades ago and hydrotreating (Groups II,III) is now taking over. It is a normal progression of technology.
If it kills the Jiffy Lube business model, I'm not shedding a single tear.
