Long time lurker, first time poster here. So, please bear with me if my searching has failed to find a thread that has already answered my question(s). According to Bendpak, "Approved fluids are any general purpose ISO-32, ISO-46, or ISO-68 Hydraulic Fluid, approved Automatic Transmission Fluids such as Dexron III, Dexron VI, Mercon V, Mercon LV, or any synthetic multi-vehicle Automatic Transmission Fluid." Although it never really gets cold here in southeast Florida, I am planning to fill the system with something like either Miles Ultihyd Bio ISO 32, Super Lube Synthetic ISO 32-46, or Renewable Lubricants Bio-Food Grade ISO 32 because, based on my admittedly limited knowledge, my first choice is to use a clear, synthetic, anti-wear, iso 32 hydraulic fluid. Besides the cost, is there any reason that I should not use one of those hydraulic fluids? If so, what's a better alternative/why? From system efficiency and from anti-wear perspectives, would a Dex, Merc, or universal synthetic ATF or another hydraulic fluid be superior? If so, feel free to learn me up! Thanks in advance.
