hydraulic oil question

[renewablejohn]

10w30 is universal oil, you can run it in engines or tractor backends etc so should be fine

 

It's attitudes like that which nearly cost me a new Merc hydraulic pump. My mb trac went in for a clutch change at a well known unimog dealer. Got the tractor back with hydraulics not working and confused with time on the bill for sorting out hydraulics. Could not understand as hydraulics where fine when it went in. Turns out Merc pump requires super thin like water hydraulic 10 oil not the thick stuff they put in. So after draining and refilling with 50ltrs it saved £800 on a new pump.

I have used super universal oil for 2500 hrs in the hydraulic system of a tracked chipper with no failure yet!!

I was told to put 15/40 eng oil in the hydraulics of our 751 bobcat its been in there 12 years so must like it.

Pretty interesting post, lots of different opinions. I would be inclined to follow manufacturers guidelines though. If their engineers recommend a certain type of oil i would imagine its for good reason.
