Mag 1 6 Quart -50°F Hydraulic Oil for Snow Plows - Cold-Weather Anti-Wear Fluid

Mag 1 6 Quart -50° Snow PLOW Hydraulic Oil is a cold-weather, anti-wear hydraulic fluid formulated to protect plow systems down to -50°F and directly replaces Meyer 15134, Fisher 28531, and Western 49311.

When winter equipment faces sub-zero temperatures and heavy-duty cycling, the right hydraulic fluid matters. This Mag 1 hydraulic oil uses FMX friction-management chemistry and anti-freeze additives to maintain pumpability, reduce metal-to-metal wear, and preserve valve and cylinder performance in extreme cold. It’s blended to meet the specifications of common OEM part numbers so you can swap fluids without compatibility concerns.

How does this oil protect plow pumps and cylinders in freezing weather?

The formula contains anti-wear agents and cold-flow additives that keep fluid viscous enough to circulate at very low temperatures while forming a molecular film on metal surfaces. That film reduces direct contact between moving parts, limiting scuffing and surface fatigue during repetitive strokes.

• FMX friction-management molecules create a wear-resistant barrier
• Anti-freeze additives maintain flowability to -50°F
• Anti-wear chemistry reduces pump and valve scoring

Will this product work with my Meyer, Fisher, or Western plow system?

Yes — Mag 1 lists direct cross-references to Meyer 15134, Fisher 28531, and Western 49311, plus other common OEM part numbers. It’s formulated for systems that require a cold-weather hydraulic fluid and is suitable where those replacement numbers are specified.

• Direct replacements: Meyer 15134; Fisher 28531; Western 49311
• Also compatible with Buyers, Boss, Sno-Way replacement numbers
• Designed for high-pressure plow hydraulics and valves

How does Mag 1’s FMX technology improve longevity and reliability?

FMX Technology focuses on friction management by bonding advanced molecules to metal surfaces, forming a protective layer that lowers friction coefficients. This mechanism helps components run cooler, reduces wear rates, and extends service intervals compared with untreated fluids.

• Molecular bonding forms a continuous protective film
• Reduces friction-related heat and component stress
• Contributes to longer pump and seal life under heavy loads

What maintenance benefits can I expect after switching to this hydraulic oil?

Using a fluid designed for extreme cold reduces startup strain, minimizes cavitation risk in pumps, and can lower the frequency of repair due to wear. Operators often see steadier control response in low temperatures and fewer cold-related failures when the correct fluid is installed.

• Smoother actuator and cylinder movement at low temperatures
• Reduced wear-related downtime and repair costs
• Consistent performance across wide temperature swings

Who this product is for: Professional snow contractors, municipal fleets, and homeowners who operate plow-equipped vehicles in sub-zero climates will benefit most. It’s intended for anyone running Meyer, Fisher, Western, Boss, Buyers, or Sno-Way plow systems that require a heavy-duty hydraulic fluid engineered for extreme cold and high-pressure service. If you need reliable cold-start performance, reduced wear on hydraulic components, and a direct cross-reference to common OEM part numbers, this Mag 1 6-quart package provides a ready-to-use solution.
