Our Base Oils

01 – WHY STAR Base Oils

Consistently recognized for quality, our STAR Base Oils are used as a key component in a broad spectrum of lubricants – including auto, industrial and functional fluid applications.



Recognized for consistent quality and outstanding service.

We have what matters most to you: a reliable supply of competitively priced, quality products. At our world-scale refinery in Port Arthur, Texas, we operate three lube hydroprocessing units that use Motiva-patented unit designs to upgrade heavy gasoils into high quality premium base oils.

Motiva’s base oil manufacturing, refining, sales and marketing operations are ISO 9001:2015 certified. Our ISO accomplishments help protect the environment and maintain the health and safety of our employees, customers, and neighbors.

03 - Optimal Blend Stocks

Largest Base Oil Plant in North America

Motiva's STAR Base Oils are hydrotreated, isomdewaxed, and hydrofinished to produce high VI, water-white paraffinic lube oils. Processing conditions are optimized to produce premium quality base stocks with high saturates and low sulfur.

STAR Base Oils are used to manufacture products meeting the stringent requirements for automotive and industrial lubricants. The very low sulfur content of STAR Base Oils make them a desirable blend stock for modern Low SAPS (Low Sulfated Ash, Phosphorus, Sulfur) engine oil formulations. They can be used to blend industrial lubricants in ISO-VG 10 through ISO-VG 100. With the use of an appropriate heavier base stock, STAR Base Oils also can be used to blend industrial products in the ISO-VG 150 through ISO-VG 460 range.

STAR 2 is a 60 SUS oil, well suited for specialty fluid, and very light viscosity applications.

STAR 4 is a 105 SUS oil, designed for PCMO (passenger car motor oils), ATF (automatic transmission fluids), and industrial applications (such as hydraulic fluids and turbine oils).

STAR 6 is a 220 SUS oil, designed for HDEO (heavy-duty engine oils), PCMO, gear oil, and other industrial fluid applications. Its high saturates content can help provide good soot dispersancy for HDEO formulations.

STAR 12 is a 600 SUS oil, designed for applications including engine oils, gear oils and industrial lubricants.

Motiva STAR 4, STAR 6, and STAR 12 base oils meet the API 1509 definition and the ATIEL Code of Practice definition for Group II base stocks.

Motiva STAR HVI 4 and STAR HVI 6 are Group III base stocks. They are designed with the low-temperature properties and volatility control needed to help produce a wide range of 0W to 15W fuel efficient engine oils.

Motiva STAR HVI 4 and STAR HVI 6, together with Motiva STAR Group II stocks, can help formulators and blenders cover a wide range of Automotive and Industrial applications.
