[Amel] Re: Yanmar 100HP engine oil change

Hi Giovammi,

Yes, I received 2 binders. One has a printed copy of the PowerPoint
presentation that was given and the other is a shop manual type of binder.

I am fairly sure that these items are copyrighted. However, if they
are not I will see about scanning them and posting them on this
website. I will have an opportunity to do that when we fly from New
Zealand to the US in December.

I attended a 3-day diesel workshop sponsored by Yanmar. I worked on,
assembled, and disassembled a 4JH3-HTE for 3 days. The class
consisted of 12 folks, but I was the only one who owned a 4JH3-HTE so
I received 1 on 1 time.

It is easy to get confused on this issue because Yanmar makes some
engines that use synthetic oil, but not the 4JH3-HTE.

According to the Yanmar instructor, Yanmar reccomends against use of
synthetic oil in the 4JH3-HTE. I believe it has something to do with
the Turbo, but not 100% sure. He said that if you use synthetic oil
in your Yanmar during the warranty period this will void the warranty.
You are probably out of the warranty period, but with Yanmar's
position on this issue, I would advise caution. I think I will listen
to Yanmar on this issue because the downside is just not worth the
