In the application of my diesel pusher motorhome I use dino ATF for the Vickers hydrostatic fan/power steering system. Basicly a hydraulic system VI numbers or viscosity is the single most important factor in the selection of the fluid.
I'm contemplating replacing the ATF with a full synthetic ATF ( specifically Redline High Temperature Synthetic ATF). I've tried to get a responce from Redline to see if they have conducted Vickers M 2952S pump test using the 35VQ25A rotary vane pump.
Physical compatability isn't a problem but I want a high VI number with good starting viscosity at ambient temperature.
Does anyone have knowledge that would help me with this decision?
thanks , dave
