The FSS was developed with Mercedes over 20 years ago. It didn't make it into many US Chrysler vehicles other than those that were manufactured in partner with Mercedes, like the Chrysler Crossfire. Mercedes stopped using it in the mid 2000s as well.
FCA vehicles use an algorithm based on engine and environmental conditions. There is no "digital oil quality dielectric sensor" in Rams for sure.
Interesting Letter to then-Daimler Chrysler CEO outlining some industry and Chrysler-centric oil [sludge] issues, including the FSS, from 14 years ago. Also for those interested, that site is a great resource for finding out if your make/model car has any open or closed lemon law info.
