What type of hydraulic oil caterpillar forklift?

Caterpillar forklifts typically use hydraulic oil that meets the ISO 46 or ISO 68 viscosity grade, depending on the operating temperature and specific model requirements. It's essential to use hydraulic oil that complies with Caterpillar's specifications, such as CAT HYDO or equivalent, to ensure optimal performance and longevity of the hydraulic system. Always consult the operator's manual for the specific type and grade recommended for your forklift model.
