We have discussed what oil is appropriate for new Kubota Mowers, and some questions as to all this oil spec business seemed left unanswewred, at least to me.
I have a brand new ZD331-LP mower, 5 hours on it now. Itgives viscosity ranges in the owners manual, but does state not to use a CJ-4 spec oil. So I finally wrote Kubota myself, and challenged this. I asked them "Why would Kubota prohibit the use of the latest generation spec oil for diesels in their machines? The 2007 and newer diesels in all cases I know of require the use of a CJ-4 oil, why is Kubota forbidding this use"
The answer I gpot back, was---"use an oil with an API rating"
This answer is not pertaining to my question, or what their own manual says. So I replied back on that e-mail answer, that they must have misunderstood my question. I re-sated that I wanted to use either Chevron Delo, or Mobil Delvac in 10W/30, API CJ-4 API spec product. For my ambient temps, I reminded them that they allowed in the manual--- 10W/30 to be used. They wrote back again that my question would be sent higher up the engineering chain to those who could answer my question.
This does not settle in my mind at all, that I want a Kubota tractor next year. Is this question so hard? They say no CJ-4. I just want to know why?
