hydraulic fan oil and filter

[Dan Williams]

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.
