I don't know what the brand is, but I'm certain Deere doesn't refine their own oil. It may be listed on the package. All their oil is probably packaged under the Deere label by the same company.
Non detergent was always the break in oil we preferred with all engines from the past. I'm not familiar with Yanmar diesels, but virtually all late model engines use newer technology in regards to pistons and rings. There are no new car, light truck, diesel truck or gas or diesel rv's using non detergent or break in oil any more to my knowledge.
In my opinion, varying engine speeds and load during break in and not idling the engine are the most important factors to seat rings. I wouldn't worry about the oil being changed as long as it is a good quality oil with proper ratings.
