Bio-80W90 Gear Oil is designed to meet the GL-4 requirements of spiral bevel transmission and moderate service hypoid gears. This formula has combined stabilized high oleic basestocks technology with snythetic basestocks and mild extreme pressure/antiwear additives.

Bio-E.P. Gear Oils are designed to meet and exceed the U.S. Steel 224, AGMA 250.04, DIN 51517, Part 3, David Brown DB S1.53.101, and Cincinnati Milacron E.P. performance requirements.  Bio-E.P. Gear Oils are recommended for lubricating spur, helical, bevel and worm gear configurations that are subject to heavy loading or shock loading and are designed for heavy-duty applications.

Bio-TC-W 2-Cycle Engine Oil is a readily biodegradable formula with proven technology that has passed the National Marine Manufacturers Association Certification Test TC-W (BIA) and TC-WII for 2-Cycle Engine Oil.

Bio-TC-W3 2-Cycle Engine Oil is a readily biodegradable formula that passes the National Marine Manufacturers Association Certification Test for 2-Cycle Engine Oil and the requirements for high-performance air-cooled engines.

Soy-based biodegradable, air-cooled, two-cycle engine oil. Exceeds the performance of petroleum fluids and meets ISO GD, JASO FC requirements.

Premium oil designed as a high temperature lubricant to reduce friction, heat and wear. It minimizes carbon deposits and contains a no-ash formula that reduces spark plug fouling. Designed for low emmissions.

Sterling Grade 4-Cycle and 2-Cycle lubricants are natural base oil derived from oil seed crops (including soy) blended with high-quality, nontoxic additives. The technology provides increased oxidative stability compared to petroleum oils and even many synthetics in tests conducted by independent laboratories.

Small engine oil.

Super-High-Performance 2-Cycle Engine Oil, specially formulated for high-performance applications, is a readily biodegradable formula with proven technology that has passed the National Marine Manufacturers Association (NMMA) certification test TC-W (BIA) and TC-WII for 2-cycle engine oil.

SAE: 75W, 80W, 80W90, 80W140. Provides extremely high film strength and increased gear life with an energy-conserving formula.  These Super-High-Performance Gear Oils are designed to exceed GL-5 EP.

SAE: 0W20, 5W30, 10W40, 15W50, 20W60, 20W70. These high-performance racing oils have exceeded the performance of conventional petroleum-based products and have shown performance equal to and better than synthetic formulas.
