Can I use hydraulic fluid instead of hydraulic oil?

Hydraulic fluid and hydraulic oil are often used interchangeably, but they can have different properties depending on their formulation. Hydraulic fluid typically refers to any fluid used in hydraulic systems, including water-based fluids, while hydraulic oil usually refers to petroleum-based or synthetic oils designed specifically for hydraulic applications. It’s essential to use the fluid specified by the equipment manufacturer to ensure optimal performance and prevent damage. Always check compatibility and specifications before making a substitution.
