loader can use either hydraulic oil as it is a dedicated system
What is the other choice? Either implies one of two choices.
Please clarify and maybe give make, model, year, special features etc.
Do you mean if given choices between UTF and AW hydraulic oil, which is the better?
If this fluid does not provide lubrication for a gearbox or wet clutches, then generally speaking, an AW Hydraulic fluid of the proper viscosity will suffice. The reason for mentioning UTTF in the Operators manual is that many companies are specifiying UTTF as a general replacement for AW hydraulic oil, since you only have to stock one fluid for a mix of machines.
