Okay, I had Blackstone do a VOA http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1062417#Post1062417 on this oil, and, now I've had a chance to get some hours (about 75) on the J-D "Supreme Plus 50" OW-40 semi-synthetic I've begun using in my X595 http://www.deere.com/en_US/ProductCatalo...=SKU20474&tM=HO mower. According to the MSDS sheets, the OW-40 is made by XOM in Canada.
The unit is a 24 HP Yanmar 3 cyl diesel; has 250 hrs on it; a Wix/NAPA 1365 filter was on there for this run. I changed the oil at 75 Hrs, a month or so shy of 1 year's use, even though I could have run it a bit longer, because I'd never used the J-D 0W-40 stuff before, and wanted to be sure. Prior to this, it had been RTS 5-40, which worked well, per usual.
The silicon content is high, which bothers me, because I recently installed new primary and secondary air filters. Maybe I didn't get them in there properly, so I have to check that out. You have to scrunch your hand down in there to get the filter in and can't get your head in to see for sure if it's seated properly. Unless you take the hood off, that is.
Anyway, on to the UOA:
RON: Engine wear appears normal at 250 hours. Universal averages show normal wear from the Yanmar 3-cylinder after about 85 hours (weird - it says 75 on their form) use on the oil. All of the wear metals read around averages for this type diesel indicating normal wearing parts and careful operation of this vehicle. Silicon at 22 ppm may be an anti-foaming additive in this brand/type of oil. It can also come from silicone lube used on the oil filter gasket or it's from dirt escaping past the air filter. The TBN was 7.4, showing loads of active additive left. 1.0 is too low a reading. Nice wearing Yanmar!

Love those Zinc/Phosphorous numbers!! I'm a high-ZDDP'er.
