My 97 Ford New Holland 555E says to use 134D oil in the hydraulic system for backhoe and loader. I have a pail of AW46 that I used on my last 1979 Ford 755 hoe/loader can I use this AW46 in my new hoe/loader?
I would use it.
Im not gon a say yay or nay , as long as the hydruali system draws its oil from its own tank and not the tranny like a john deere it should be ok ,but mixxing oils is usually not recommended
Good point Walker.
