Three Primary Re-Refinery Products
Our re-refinery processes up to 75 million gallons of used oil annually into three primary products: Group II base oils, vacuum tower asphalt extender, and hydrotreated fuel oils. Our HCC 150 Group II base oil, when formulated with additives, exceeds API SP and ILSAC GF-6 standards for passenger car motor oils and API CK-4/SM for heavy duty engine oils. Average daily production includes 3,000 barrels of Group II base oils, with monthly production of 20,000 barrels of asphalt extender and 9,000 barrels of low sulfur fuel oil.
All base oil products undergo laboratory testing to meet or exceed API and ILSAC industry standards, suitable for automotive, industrial, and marine lubricants, as well as diluents for additives and process oil applications.
Group II Base Oils
Crystal Clean’s HCC 80 Group II Base Oil is a mid-viscosity, high-purity base oil designed for use in a wide range of lubricants — from industrial fluids to automotive and marine formulations. It offers excellent oxidation stability, low volatility, and superior cleanliness, ensuring long-term performance and reliability.
With its consistent properties and compatibility with major additive systems, HCC 80 helps lubricant blenders create finished products that meet demanding operational standards.
Our flagship HCC 150 Group II Base Oil delivers the highest quality and consistency, exceeding major industry standards — including API SP, ILSAC GF-6, and API CK-4/SM when blended with additives from leading suppliers.
Beyond performance, HCC 150 represents a significant environmental advantage. A third-party verified study by ClimeCo found that Crystal Clean’s HCC 150 re-refined base oil has a 77% lower greenhouse gas footprint compared to virgin base oil. By choosing HCC 150, customers gain a proven, sustainable alternative that performs to the highest specifications while supporting carbon reduction goals.
Vacuum Tower Asphalt Extender
Vacuum Tower Asphalt Extender (VTAE) is a heavy, viscous product used in asphalt blending and road construction. It enhances pavement flexibility, durability, and performance, making it a preferred choice for asphalt manufacturers seeking a reliable, cost-effective solution.
VTAE replaces traditional virgin asphalt extenders with a re-refined alternative that lowers environmental impact without compromising quality to support a more sustainable infrastructure.
Hydrotreated & Distillation Fuels
In Crystal Clean’s Hydrotreater Unit (HT), Hydrotreated Low Flash Fuel (HTLF) is produced as part of the re-refining process that upgrades Vacuum Gas Oil (VGO). This light, refined fuel is highly flammable and offers clean combustion with minimal odor, making it well-suited for industrial heating and blending applications.
HTLF delivers consistent performance while helping businesses minimize emissions and meet modern efficiency standards.
Hydrotreated Low Sulfur Fuel (HTLS) is another fuel product from the Hydrotreater that meets stringent environmental requirements. With a significantly reduced sulfur content, HTLS provides an environmentally responsible option for commercial and industrial use.
Its stability and cleanliness make it ideal for customers seeking a balance between performance and compliance with clean fuel standards.
Light Distillate Fuel (LDF) is a clean-burning fuel used across industrial and manufacturing applications. As a recycled, renewable product, LDF provides dependable energy output while helping customers reduce their reliance on virgin petroleum.
By capturing value from used oil, Crystal Clean’s LDF turns a potential waste stream into a practical, sustainable energy resource.
Verified Environmental Performance
Independent life cycle assessment by ClimeCo confirmed that HCC 150 re-refined base oil produces 77% lower greenhouse gas emissions compared to virgin base oil production. Re-refined base oils deliver identical performance to virgin products while reducing environmental impact through used oil recycling and efficient re-refining operations.
