I believe the esters in AutoRx are based on lanolins. For some reason, they do not work well with synthetics, so they recommend one uses dino oil for their "clean and rinse" cycles.

The old Mobil 1 contained esters, but no longer: it's all PAO, at least in the normal version (I don't know about the new extended life product). Esters in the original Mobil 1 of 1980-vintage caused leaky seals.
