Additives help to extend the life of machinery. They protect against rust, wear and other issues affecting machinery. Using additives can also address the change in viscosity created by extreme degrees of temperature. Whether the weather is hot or cold, blending additives into the hydraulic fluid will work to protect the mechanical systems as they operate in these sometimes extreme conditions.
