Hydraulic oil

Alright, so you know how water can be used to help plants grow by providing them with the nutrients they need? Well, hydraulic oil is kind of like that for machines.

Machines need something to help them move and work properly, and hydraulic oil is what does the trick. It's like a special kind of juice that goes into the machine's "veins" and helps it do its job.

This oil is very important because it helps reduce friction and wear and tear on the machine's parts, which means the machine will last longer and work better. It's also really good at resisting heat and pressure, which can be a big problem for machines if they get too hot or have too much pressure on them.

So just like plants need water to grow, machines need hydraulic oil to do their jobs and stay healthy. And that's what hydraulic oil is all about.
