I have a steel hydraulic floor jack. Today I took it out to work on the car. At some point in the past month since it was out last it got turned upside down, & there's some oil residue on the top of it. Now when I jack it up, there's real bad creep. I barely had time to get the jack stands under before the jack started to lower.

I assume some fluid leaked out, though that tiny bit of residue isn't much at all. Maybe it just needs to be bled? Does anyone know about hydraulic jacks, and what kind of fluid can I use if it needs to be topped off?
