hydraulic fan oil and filter

[Kurt Horvath]

Dan,

I did a lot of research, there are a lot of new oils out there. I liked the new
biodegradable type but they do not hold up as well as the Dino. oils or Syn.
oils. I ended up going with the original recommended oil for my coach Rando
32AW. I just could not locate anything I though had any advantage to the Rando.
I've had this stuff around since the late summer. I am just now getting ready to
doing the service on it.
