Royal Purple composition

[KJA426]

Quote from RP's site. Royal Purple motor oils are composed of a proprietary formulation of synthetic basestocks and synthetic additives containing iso-paraffinic diluents.

What exactly is an iso-paraffinic diluent? Anything paraffinic sounds like regular oil to me.

That's just the additive carrier oil which makes up only small fraction of the motor oil. Don't worry about that. RP does not disclose what basestocks they use.

I had some thoughts that it might be something like that. Thanks
