[AT] Off-topic: Bobcat hydraulic fluid

[charlie hill]

David,  not trying to be argumentative but what brand of hydraulic pump is 
on a Bobcat loader?
I'm willing to bet Bobcat did not manufacture the pump.  The oil needs to be 
what works correctly
with the pump regardless of it being Bobcat OEM or aftermarket.

Spencer,  if I may weigh in here,  I had my oil supplier test a sample of 
new Bobcat oil.
They (a major company that only refines US oil for commercial use) said 
there are some additive packages in use in the Bobcat oil they couldn't be 
sure of.  They highly recommended using the OEM oil instead of their close 
equivalent.  This message was straight from their labs.  I have taken their 
advice.
My experience only and yes, this is the only example of this in our fleet. 
Everything else is running a top quality, 'generic', oil.
David
