Buying advice

Choose a hydraulic oil based on your system's viscosity requirements (e.g., ISO 32, 46, 68) and operating conditions. Synthetic oils offer better performance in extreme temperatures and longer drain intervals, but are pricier. For older equipment, check compatibility with seals and materials. Popular brands like Mobil, Castrol, and Shell are reliable choices. Always verify the product's intended use to avoid using engine oil in hydraulic systems unless specified.
