Not sure what you are asking. If I may make an assumption, it sounds like a bit of an "old school" question.
Here's some words/terms to look-up/learn:
paraffin(ic)- does not mean always "wax" in organic chemistry terms, more specifically in oil speak - really just means longer chain saturated alkanes. Any petroleum oil is mix of all sorts of these hydrocarbons.
napthene(ic) - basically ringed organic compounds, such as benzene
Base Oil groups I-V (and now VI!)- covered elsewhere in detail.
It's also worth learning about synthetic oil, to better understand the terms and gain a better handle on the knowledge
