Hydraulic oil for models - what's in it?

[Espeefan]

Jeff and Joe, thanks for the info. I'm going to do a little more digging. I've been searching the net for some miniature hydraulic pumps and I found a company that claims to custom design pumps for any type of fluid. Their normally stocked pumps are designed for pumping fuel, so I was thinking if I knew what kind of oil I needed to pump, I could ask them what they'd suggest for the job. These pumps are small enough to fit inside the fuel tank of my Wedico, which was my plan from the start. That way I can have a wet kit on my truck for running a dump trailer or something else.

some one on the late GT had it tested through cat, and turns out to be the same as cat 10w hydro oil . Since I had some on hand after I went through the oil that came with my wedico cylinder kit , I've been using it with no problems . Looks nearly Identical .
