Dan: Have you had the coach out on the road recently.
If oil is
brown on the bottom, then it sounds like it has been setting still and
some solids have settled. Please do inform me of the analysis.
I use a software to keep all my records. It is called Rolling Stock.
It was designed by a friend of mine and several fleets use it. Not
sure what it cost right now. I was a Beta Tester on it several years
back. If you are interested in it, I'll send you a URL to look at it.
It has a Reminders page to let you know when the next services are due.

Dan,
"INDICATES THIS IS 20 WEIGHT OR EQUIVALENT OIL. OTHER ANALYSIS READINGS APPEAR
TO BE ACCEPTABLE.",
You should check on that 20 weight, that does not sound correct. I think 10w/30
is what your coach should have in the hydraulic system.

Kurt, Yes, I am going to change it.
10w/30 motor oil was recommended back in 1988 but there have been some
advancements in hydraulic fluid since then. I wonder what I should use now?

Dan,
"INDICATES THIS IS 20 WEIGHT OR EQUIVALENT OIL. OTHER ANALYSIS READINGS APPEAR TO BE
ACCEPTABLE.",
You should check on that 20 weight, that does not sound correct. I think 10w/30
is what your coach should have in the hydraulic system.

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.
