I recently purchased a Yanmar 1500D. When the meter tuned 300 (not sure if that is total or if it has rolled over) I changed the oil. It now has almost 304 and the oil is still clear. I thought diesel engines carboned up the oil almost as soon as they were cranked. Is this a good or bad sign?

Welcome to the forum. I split your post off into it's own thread for better exposure. I'm sure the next request will be for pics of the tractor.

I'm not a Diesel guy so I can't answer your question, But I'm sure someone will be along who can. Welcome aboard.

I'm not a diesel guy either but I'd assume a good condition engine wouldn't carbon up the oil right away.

It might have just 300 hours, that would explain the lack of soot, what is what turns the oil black in a diesel. Or the previous owner was very religious with his oil changes and kept it flushed out. OR the third option, when the tractor was reconditioned, the oil pan was pulled and the engine flushed out. If its running good with no issues, keep on running and be happy. Mike

Thanks to all of you for the warm welcome. I have never had a diesel tractor so it is all new to me. I had just read/heard that a diesel will soot up the oil almost as soon as you start it. So, I was a little surprised when after four hours on the new oil (Rotella) that the oil was still clear. The tractor runs like a top. Thanks for the assurances that all is OK. I would really be surprised if the little tractor only had actual 300 hours but I suppose it is possible.

How do I post a pic of the tractor?

That is a GOOD sign. Engine is clean inside and had the oil change at regular intervals. I would not let the oil change interval go over 50 to 100 hour though. Less if the tractor does not get a lot of hours.

I bought a YANMAR 1500D about 2 years ago, it had just over 300 hours on it which I believe is correct so it is entirely possible. After some searching, I believe mine is a mid 70's model, it is a grey market, red tractor, original rubber, everything works on it.
