Why are synthetic oils increasingly used in hydraulic systems?

The increasing use of synthetic oils in hydraulic systems can be attributed to several key advantages they offer, which all contribute to their overall effectiveness and reliability.

A high resistance to oxidation helps synthetic oils maintain their properties over extended periods, especially under high temperature and pressure conditions typical in hydraulic systems. This characteristic ensures that the oil does not break down easily, helping to reduce wear on components and maintain system efficiency.

A high viscosity index indicates that synthetic oils maintain their viscosity more consistently across different temperatures. This stability is crucial for hydraulic systems, which can experience wide temperature variations during operation. Synthetic oils provide optimal lubrication performance in both high and low temperatures, helping to ensure smooth operation and reduced chances of failure.

The longer life of synthetic oils is a significant advantage, as they can outperform conventional oils in terms of durability. This leads to less frequent oil changes, lower maintenance costs, and less waste generation. The extended life of synthetic oils also means that hydraulic systems can operate more reliably over time, enhancing the overall performance and reducing downtime for maintenance or repairs.

In summary, the benefits of high resistance to oxidation, high viscosity index, and longer life collectively make synthetic oils an increasingly preferred choice for hydraulic systems, which leads to their widespread adoption in various applications.
