Hydraulic oil is too important for the jack. The whole hydraulic jack can normally exert force on the heavy objects under the action of hydraulic oil pressure. With the long use of the jack, will the hydraulic oil expire?

In fact, the hydraulic oil is not so much expired as deteriorated. Generally, the shelf life of grease products is very long, but the service life is often not that long, because many factors will deteriorate them. High temperature, impurities, low temperature and oxidation will affect its oil quality. Once it deteriorates, its viscosity will change, which will seriously affect the normal use of the jack.

As for the hydraulic oil of the jack, there is no difference between deterioration and expiration, so you must pay attention to protection and replace the internal hydraulic oil regularly to avoid affecting the normal use of the jack.
