What Is the WHITMORE Enclosed Gear Oil Line and Who Is It For?
WHITMORE manufactures six enclosed gear oil products targeting heavily loaded gearboxes in surface mining, mineral processing, and severe industrial service: Paragon, Paragon Gold, Paragon Syn Blend, Decathlon Extreme, Decathlon F, and Multiplus. Every product in the line addresses a specific performance gap — from conventional mineral-oil protection under high shock load to fully synthetic PAO formulations for wind turbines and haul-truck final drives.
All products are manufactured at an ISO 9001 and ISO 14001 registered facility in Rockwall, Texas.
How Does WHITMORE Paragon Heavy Duty Enclosed Gear Oil Protect Mining Equipment?
Paragon Heavy Duty Enclosed Gear Oil is formulated specifically for surface mining and mineral processing equipment subjected to high load, shock load, and reversing motion. It meets DIN 51517-3 across ten viscosity grades from ISO 68 (AGMA 2EP) to ISO 1500 (AGMA 9EP).
- Four Ball EP Weld Point: 500 kg across all grades (ASTM D-2783)
- Timken OK Load: 60–70 lb depending on grade (ASTM D-2782)
- Four Ball Wear Scar Width: 0.40 mm across all grades (ASTM D-4172)
- Flash Point: 400°F (204°C) minimum; 425°F (218°C) for ISO 1500
- Pour Point: as low as -45°F (-43°C) for ISO 68 grade
- FZG Test: passes Stage 12+ for ISO 220 and higher grades
- Oxidation stability: less than 6% viscosity change (ASTM D-2893)
The tacky additive system allows a protective film to cling to gear surfaces during long shutdowns, reducing startup wear.
What Makes WHITMORE Paragon Gold Different from Standard Gear Oils?
Paragon Gold uses a eutectic formulation that stops scuffing by forming a protective chemical layer at the asperity contact zone. Rather than micro-welding under high load, opposing surfaces are smoothed by the pressure — a mechanism Whitmore describes as the eutectic smoothing effect. Lab and field testing confirm extremely low wear and friction levels.
A key operational benefit: the eutectic action will partially flatten pre-existing wear damage, typically within a few hundred hours of operation, allowing condemned equipment to remain in service until a scheduled shutdown. Pitting — caused by metal fatigue — is also reduced because a smoother surface distributes load more evenly.
- Available in ISO grades 220 through 1500 (AGMA 5EP–9EP)
- Viscosity Index: 111–115 across all grades
- Four Ball EP Weld Point: 500 kg (ASTM D-2783)
- Flash Point: 390–500°F (199–260°C) depending on grade
- Oxidation stability: less than 6% viscosity change
- Copper Strip Corrosion: 1B (ASTM D-130)
Paragon Gold meets DIN 51517-3. It is recommended where conventional gear oils fail, where long component life is essential, or where oil change intervals cannot be shortened.
When Should You Choose WHITMORE Paragon Syn Blend Over Mineral Oil?
Paragon Syn Blend is a synthetic blend (not full PAO) formulated to operate from -40°F (-40°C) to 275°F (135°C) — a range exceeding conventional mineral gear oils. The synthetic component provides higher shear stability, extending drain intervals and reducing gearbox operating temperatures.
- Available in ISO grades 150–1000 (AGMA 4EP–8A), all rated GL-5
- Meets GL-2 through GL-5 and Mil-L-2105C specifications
- Viscosity Index: 107–132 depending on grade
- FZG Test: passes Stage 12 across all grades
- Four Ball Wear Scar Width: 0.37 mm — lower than Paragon mineral at 0.40 mm
- Flash Point: 430–460°F (221–238°C)
- Not suitable for worm gearboxes
Paragon Syn Blend is compatible with conventional petroleum and most synthetic gear oils, except PAG (glycol-based) synthetics. It is non-corrosive, compatible with seals, and rated 1B on ASTM D-130 copper strip corrosion.
How Does WHITMORE Decathlon Extreme Synthetic Gear Oil Handle Severe Load and Cold Starts?
Decathlon Extreme is a fully synthetic EP gear oil designed for gearboxes experiencing heavy load, shock loading, frequent reversing, overheating from internal friction, or exposure to cold weather. ISO grades 150–680 meet GE specification D50E35 for off-highway vehicle gearboxes including Komatsu, Terex, and Hitachi haul trucks.
- Viscosity Index: 151–170 — among the highest in the Whitmore line
- Pour Point: as low as -42°F (-41°C) for ISO 150 grade
- Flash Point: greater than 475°F (246°C) across all grades
- FZG A/8.3/90: passes Stage 12 all grades
- FZG Micro-Pitting FAG-FVA 54: passes Stage 10 all grades
- Copper Strip Corrosion: 1A (better than 1B) per ASTM D-130
Decathlon Extreme additionally meets AGMA 9005-E02, DIN 51517-3, US Steel 224, ISO 12925-1 CKD, David Brown S1.53.101, GM LS-2, and Cincinnati Machine Gear specifications. It was designed to meet Hitachi specifications for EH4500 series, EH4500-2 series, and EH5000 series dump truck final drive planetary gears and front wheel bearings.
What Gearboxes Is WHITMORE Decathlon F Designed For?
Decathlon F is a fixed-formulation Group IV PAO synthetic oil in a single ISO 320 grade, meeting Flender specification 6/12/2005 Rev. 9. It is specifically recommended for Bucyrus equipment fitted with Flender-manufactured gearboxes. Applications include wind turbine gearboxes, cranes, mining machines, crushers, and extruders.
- ISO 320 only; kinematic viscosity 252–288 cSt @ 40°C
- Viscosity Index: 157
- Pour Point: -44°F (-42°C)
- ISO 6614 demulsification at 180°F (82°C): rating of 15
- Recommended where oil operating temperature exceeds 175°F (80°C)
It also meets AGMA 9005-D94, U.S. Steel Specification 224, and DIN 51517-3.
How Does WHITMORE Multiplus Handle Automotive and Off-Road Differential Service?
Multiplus Enclosed Gear Oil is designed for automotive differentials, transmissions, and severe service off-road fleets. It is available in SAE 80W-90 and 85W-140 and meets an extensive specification list including GL-4 and GL-5, MIL-L-2105E, U.S. Steel Spec 224, John Deere J11D, Navistar grades 81HR/90HR/135HEP, Ford EST-M2C-108-C, Mack GO-J, and MT-1, among others.
