All group III oils are parafinic hydrocarbons and are pumped from the ground.

Go figure, most synthetics that are mentioned here now are a Group III. With the exception of the GC, most "Synthetics" are really hyrdrocracked group III oils that have been through a strict distillation/processing and are considered a full-synthetic.

The lucas oil stabilizer is just a base oil viscosity modifier. By using it, you are basically diluting your oil and lowering the additive %. Sometimes keeping the viscosity is more important, but I wouldn't trust it without another additive.
STP oil additive is cheap, and has good amounts of ZDDP and Moly. It is cheap insurance and you can find it everywhere.
