Who owns Excel Paralubes LLC
One company in the researched set discloses a stake in Excel Paralubes LLC, none of it sized by anyone who discloses it. Excel Paralubes LLC is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Excel Paralubes runs a hydrocracked lubricant base oil plant at Lake Charles, Louisiana, built adjacent to and physically attached to the Phillips 66 Lake Charles refinery, which supplies its feedstock. In production since 1997, the plant makes Group II base oils, the clear, high purity stocks blended into engine oils, industrial lubricants and greases, and it ranks among the four largest Group II producers in the United States, with output moving by truck, rail, barge and vessel from the Gulf Coast. It is a 50/50 venture between Phillips 66 and Flint Hills Resources, and since 1 January 2018 Phillips 66 has been both the day to day operator and the sole marketer of the plant's output, sold under the Pure Performance brand.

Excel Paralubes LLC files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from About Pure Performance Base Oils (Excel Paralubes), Lake Charles Refinery (Phillips 66) and Phillips 66 Lake Charles Refinery project profile (NS Energy). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Phillips 66. The 50% ownership figure itself is explicitly stated in the 10-K's Lubricants business description; the carrying value is not, because Excel Paralubes is not broken out as a separate line in the 'significant investments in unconsolidated affiliates' table, per the never-invent-a-number rule. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Excel Paralubes LLC where a holder stated one, and are missing where no holder did.
