What Type of Hydraulic Fluid for Log Splitter

When it comes to choosing the right hydraulic fluid for your log splitter, it's essential to select a fluid that meets the manufacturer's specifications and provides optimal performance in various temperatures. The most common types of hydraulic fluids used in log splitters are:

• AW-32 (All-Weather 32): A multi-viscosity fluid that provides excellent performance in temperatures ranging from -20°F to 100°F (-29°C to 38°C). It's a popular choice for log splitters as it offers a good balance between low-temperature flowability and high-temperature stability.
• AW-46: A heavier-duty fluid that's designed for more extreme temperatures, ranging from -25°F to 120°F (-32°C to 49°C). It's a good option for log splitters that are used frequently or in harsh environments.
• Biodegradable Hydraulic Fluids: These eco-friendly fluids are made from renewable resources and are biodegradable, making them an excellent choice for log splitters used in environmentally sensitive areas.

It's crucial to note that using the wrong type of hydraulic fluid can lead to reduced performance, increased wear on components, and even premature failure of your log splitter. Always check your owner's manual or consult with the manufacturer to determine the recommended hydraulic fluid for your specific log splitter model.

In addition to selecting the right type of hydraulic fluid, it's also essential to consider the fluid's viscosity index, which measures its ability to maintain its viscosity in different temperatures. A higher viscosity index indicates a more stable fluid that will perform better in extreme temperatures.
