A "100% synthetic" still contains a petroleum carrier oil, from what I keep reading here. Yet the final product can be labeled "100% synthetic," because those "100%" refer only to the base stock.
Now, I'm sure that the amount of base stock and carrier oil vary from brand to brand, and probably it has to do with the additives, too. How much of the actual oil that we pour out of a bottle is actually 100% synthetic base stock?
