For the slides a clear hydraulic fluid would be best in case it leaked inside the rig before the landing gear should not make much difference. Any good loyal label as hydraulic Would be fine.
WRONG!!!!!!!! ALL RV slides and Leveling Jack systems use Dexron 3 fluid. The clear Fluid (usually supplied by HWH) is Dexron 3 without the red dye. They can be mixed. Doug
From HWH FAQ.
What kind of fluid should I use in my system?
The use of HWH Specialty Hydraulic Oil is recommended but Dexron or multipurpose transmission fluids can be used if necessary. DO NOT use hydraulic jack oil, brake fluid, or power steering fluid.
From LCI/Powergear/
The following automatic transmission fluid (ATF) recommendations for use in Lippert Components, Inc. (LCI)
hydraulic systems are based upon hydraulic system operation in various environmental air temperatures.
1. Operation at air temperatures routinely above 0 °C (32 °F)—above freezing—which also covers most
initial OEM fills.
