A VOA on J-D's semi-syn 0W-40 that I've just recently started using in my J-D X595 tractor (24 HP 3 cyl. Yanmar diesel).
RON: Everything looks fine in this sample of virgin 0W/40 oil. The TBN starts out strong at 9.4, which is a common reading for a new diesel use oil like this. The additive package is also strong and should do well in your tractor. No water or insolubles were found. The iron isn't a problem and neither is the silicon. Silicon at this level may be from a little anti-foam additive. The viscosity was right in the middle of the 40W range, though that will drop a little after the oil sees use (like it does with all oils). In any case, this oil is perfectly serviceable.

Interesting that the Blackstone VOA shows a TBN of 9.4. At the J-D page describing the product http://www.deere.com/en_US/parts/partsinfo/oils_and_lubricants/oil_0w40.html they note a TBN of 12.8. Seems like quite a difference!!
