2016 Komatsu WA320-7 A35441.
Book says to use EO10W-30-DH engine oil for the hydraulics. The hydraulics are the drive pump and motor, and tool functions. The standard for this oil is JASO DH-1 or API CI-4. I plan on using this oil, but I am still going to ask the question, is the CNH Unitek 10W-40 close to this oil? How about CNH HyTran Ultraction? I've been told that HyTran is about a 10W-30 viscosity.
The Komatsu oil is reasonable, but I can't help being irritated that I am going to have to keep another oil around. If they would spec this 10-30 for use in the engine, that would make sense, but they want 15W-40-LA for this new of an engine.
