WHITMORE Enclosed Gear Oil Guide: How Paragon, Decathlon, and Multiplus Protect Mining Gearboxes
How to select WHITMORE enclosed gear oil for mining gearboxes — Paragon, Paragon Gold, Paragon Syn Blend, Decathlon Extreme, Decathlon F, and Multiplus — is the focus of this episode. Six products, three base chemistries, one goal: keep heavily loaded mining and mineral-processing gearboxes running longer between shutdowns. Browse the full lineup at https://www.pe-energy.com/manufacturers/whitmore/lubricants/gear-oils/ Paragon Heavy Duty is your baseline for surface mining shock-load service. Ten viscosity grades from ISO 68 (AGMA 2EP) to ISO 1500 (AGMA 9EP), all meeting DIN 51517-3. Four Ball EP Weld Point hits 500 kg (ASTM D-2783), Timken OK Load reaches 60–70 lb, and wear scar width holds at 0.40 mm across every grade. Flash point minimum is 400°F; the ISO 1500 grade bumps to 425°F. FZG Stage 12+ on ISO 220 and higher. A tacky film clings to gear surfaces through long shutdowns, cutting startup wear on Monday morning. Spec the ISO 1500 pail here: https://www.pe-energy.com/product/paragon-iso-1500-pail-enclosed-gear-oils/ Paragon Gold adds a eutectic formulation that forms a protective chemical layer at asperity contact zones — opposing surfaces smooth rather than micro-weld under pressure. Pre-existing wear damage typically flattens within a few hundred operating hours, buying you time until a scheduled shutdown. Viscosity Index runs 111–115 across ISO 220–1500 (AGMA 5EP–9EP); Flash Point reaches 390–500°F depending on grade; Copper Strip Corrosion rates 1B (ASTM D-130). Spec it when conventional extreme pressure gear oil keeps failing or component life is non-negotiable: https://www.pe-energy.com/product/paragon-gold-iso-680-p2-enclosed-gear-oils/ Paragon Syn Blend operates from -40°F to 275°F — well beyond mineral-oil limits — and meets GL-5 and Mil-L-2105C across ISO 150–1000. Viscosity Index spans 107–132; Four Ball Wear Scar Width tightens to 0.37 mm vs. 0.40 mm for straight mineral Paragon. Flash Point 430–460°F. Compatible with conventional petroleum and most synthetics — not PAG glycol-based fluids. Not for worm gearboxes. https://www.pe-energy.com/product/paragon-syn-blend-iso-680-pail-enclosed-gear-oils/ Decathlon Extreme is the full PAO choice for haul-truck final drives and severe cold-start service. ISO 150–680 grades meet GE specification D50E35 and were engineered for Hitachi EH4500, EH4500-2, and EH5000 series final drive planetary gears. Viscosity Index reaches 151–170 — highest in the Whitmore line. Pour Point as low as -42°F for ISO 150. Flash Point exceeds 475°F across all grades. FZG Micro-Pitting FAG-FVA 54 passes Stage 10. Also meets AGMA 9005-E02, DIN 51517-3, David Brown S1.53.101, GM LS-2, and US Steel 224. Copper Strip Corrosion rates 1A. Order the Decathlon Extreme 150 here: https://www.pe-energy.com/product/whitmore-decathlon-extreme-150-lubricant/ — or grab the 680 in a 55-gallon drum for fleet-scale consumption: https://www.pe-energy.com/product/decathlon-extreme-680-55-gallon-drum-enclosed-gear-oils/ Decathlon F is a single ISO 320 Group IV PAO formulation meeting Flender specification 6/12/2005 Rev. 9 — the mandatory call-out for Bucyrus equipment fitted with Flender gearboxes, plus wind turbines, cranes, crushers, and extruders. Kinematic viscosity 252–288 cSt @ 40°C; Viscosity Index 157; Pour Point -44°F; demulsification rating 15 per ISO 6614 @ 82°C. Recommended when oil operating temperature exceeds 175°F.
