Think it would hurt anything to mix John Deere hy-gard ( hydraulic oil) with Cats Hydo 10 (hydraulic oil)??? I farm with John Deeres and keep a drum of that oil arround....I only have 1 Cat loader and don't want the hassel of keeping separate oil just for it. I already changed the engine oil and now my CAT runs on JOHN DEERE engine oil ... good bad or whatever lol.
As long as it is the required weight and API rating you should be fine. Sent from my iPhone using Tapatalk
The Deere Hy-gard has additives for internal clutches and brakes (like universal tractor fluid). If Hydo 10 is like straight hydraulic oil it may not be a good idea to mix them.
make sure they are the same as blazinss934 wrote "name'' isn't all that important, quility is.
OldandWorn is right. The CAT doesnt have the friction modifier that you need for wet clutches/brakes. You need a J20 rated hydo oil.
