    Dave,
    My Fleetwood Southwind has grease fittings at the bottom of the cylinder. I just pumped some grease into to them. Will that hurt anything? What kind of fluid should I use in the system reservoir?

      Hello Joe,

      Typically Fleetwood used the Power Gear leveling system which is now owned by Lippert Components Inc (LCI). According to the Power Gear manual, they recommend the following:

      Type A automatic transmission fluid (ATF, Dexron III, etc.,)will work satisfactorily.

      Mercon V is also recommended as an alternative fluid for Power Gear leveling systems operating in environments with large temperature swings

      Operating in cold temperatures (less than -10°F) may cause the jacks may extend and retract slowly. For cold weather operation, fluid specially-formulated for low temperatures may be desirable:

      Mobil DTE 11M, Texaco Rando HDZ-15HVI, Kendall Hyden Glacial Blu, or any Mil. Spec. H5606 hydraulic fluids are recommended for cold weather operation.

      The grease fittings are generally designed to add a small amount of grease to disperse moisture in the cylinder so it should be good.

      Thanks,
