What does 100% pure paraffin base mean?

Yes, the term paraffinic is used for conventional/mineral base oils as hydrocracked Grp II and higher base oils tend to have very high percentage of straight hydrocarbon molecular chains. This straight molecular structure is termed "paraffinic".
Naphthenic base oils, typically used for industrial oils, will include more round ring, "aromatic" type structures and do not have the cold temp & heat resistant properties of a paraffinic base oil.
Naphthenic oils, with the higher aromatic content, have good soluability and can be used in passenger car formulations, but generally more at an additive level.

I ask because I have had 2 different oil companys call on me. 1 was schaeffers which by googleing them brought me to this site. They claimed that they use a 100% pure paraffin with some syn. and that the mineral oil in other oils is not of the same quality. Judging by your post they must be exaggerating the facts? Is there a difference in base oils of mineral type paraffinic?
No, I have a high regard for Schaffer's products & it's not necessary for exaggerations.
I think it's the context in which the term paraffinic is used.
Link to Properties of Chevron Grp II Base Oils
Chevron lists the chemical structure of their paraffinic base oils towards the bottom of the page. As you can see, the hydrocarbon chains are 67-75% paraffinic structure and 33-25% naphthenic.
Schaffer's may be using base oils with a higher content of paraffinic structure, thus the 100% description.
- A good question for SalesRep from Schaffer's to follow-up for us!

If you look at Chevron's Group III base oil you'll see the paraffinic numbers are up in the 82% to 86% range.
Want to know why I like wax isomerate Group IIIs like Shell's XHVI? They are 99.9% paraffinic. Only PAO is higher; it's 100%.
One of the reasons Pennsylvania grade crude was such a highly prized base oil for blending motor oil back in the early days of refining was because base oils refined from it had extremely high natural paraffinic content.

Schaffer's is only a blender they dont refine there basestocks , they buy stocks from different refiners. They buy based on price so you never know what basestock you are getting in a given product. All API SM ILSAC GF-4 engine oils use high quality basestocks, what separates them is additive selection.
I don't know if they still do, but Schaeffer's use to buy a lot of base stock from Shell. They make a great product. Their blends are Group II and PAO, and as someone said, they have a great additive package.

Very , very few.
A good example of this is our 9000 series which is formulated from a single source feed stock.

Simply not the case at all.

To some extent the oem's have required the majors to up the ante. Yes we also feel as if the additives ( and quality of) in addition to the use of the highest quality base stocks in their given category and blending techniques is what seperates us.
