Bio-E.P.™ Gear Oil ISO 46-460

Bio-E.P.™ Gear Oils are designed to meet and exceed the U.S. Steel 224, AGMA 9005-E02, DIN 51517 Part 3, ISO 12925-1 CKD, David Brown DB S1.53.101, and Cincinnati Machine performance requirements. They are recommended for lubricating spur, helical, bevel, and worm gear configurations which are subject to heavy loading or shock loading in heavy-duty applications. These patented biodegradable1 formulas have combined energy conserving Stabilized HOBS technology with synthetic base stocks and exception E.P./antiwear technology. The result is a super high VI product which has the long life heat stability and additionally offers the protection advantages of increased gear life through extremely high film strength during operating temperatures. They provide rapid demulsification allowing the end user to drain water from the system quickly to prevent corrosion, protect components, and extend oil life. They are the perfect economical choice where leakage or contaminations are more prominent or equipment requires more frequent oil change intervals.


(1) Energy Conserving Formulas – Because of the super high viscosity index (VI) of the *Stabilized HOBS, these products provide a lighter viscosity (more energy efficient) in the lower start-up temperatures and an improved protective viscosity over mineral based formulas in the higher operating temperatures

(2) Super high viscosity index provides wider temperature performance

(3) Fortified with improved additive technology to resist wear, oxidation, rust, foam and water

(4) Improve bearing and gear protection with high levels of scuffing and micropitting resistance

(5) More fire resistant and improved heat dissipation and seal protection

Bio-E.P.™ Gear Oils meet the Environmental Protection Agency (EPA) 2013 Vessel General Permit (VGP) guidelines for Environmentally Acceptable Lubricants (EALs), and should be used where LOW TOXICITY, BIODEGRADABILITY and NON-BIOACCUMULATION properties are required. Bio-E.P.™ Gear Oils exceed the acute toxicity (LC-50 / EC-50 >1000 ppm) criteria adopted by the US Fish and Wildlife Service and the US EPA. Bio-E.P.™ Gear Oils are ENVIRONMENTALLY RESPONSIBLE lubricants that are formulated from renewable agricultural plant resources.
