Any oil will thin out/degrade rapidly when exposed to fuel dilution, there is no additive package that can remedy that condition. Feel free to research it if you disagree.
Aside from more frequent/wasteful oil changes, running a catch can is your only option, they work (at least the Elite has proven to work, not sure about the others). All these cars need a catch can ASAP.
