That would be roughly like 8000 miles on a semi truck. And your oil is still showing TBN of 15! :-) I can't for the life of me convince my FIL that new computer controlled diesels aren't the same old engines he grew up with. They are built tighter, atomize better and burn much cleaner than what he drove just 10 years ago. He is stuck on doing 10K oil changes. When he could stick $100-150 in the bank easy every other change. I'm sure his truck most likely could easily go 20K.

Nice wearing N14 (uggh I sounded like Blackstone for a minute please forgive me)! Looks like your limiting factor will be soot. Heck if you were to put a bypass or centrifuge on that puppy you could tack weld the drain plug before you fill it up at your next oil change and forget about it! Wear appears to be well controlled. I take it that you aren't running ULSD and this beauty has NO EGR to bother with.
Used gear lube and burnt ATF is all the cologne a real man will ever need!

The fuel is an unknown, off road diesel in our area can be either LSD or ULSD. No EGR to worry about.

Keeping the air cleaner free of pollen/seeds & dirt is a constant battle, I suspect that may have something to do with the soot.

It's worthwhile going to the site of that oil co. All their oils are very strongly formulated. The Pro-spec III has a SA of 1.72%, TBN>15, Ca 4500, Zn 1300 or 1400. If it were a 5W-40 it would be a "super-oil"; which it already is for temperate and warm conditions. The CJ4 version has a very high TBN of 14!!

How many hours do you generally you put on your unit in a year? We have a Claas unit on our farm and the last two years put on about 370 hours each. I'm guessing we'll go over that this year though as we're looking to chop a lot more corn. What type of oil filters do you use? The Fleetguard combo filters work real well in some of our applications in keeping soot down. With an N14 you'd probably want to look for an LF9009.

The TRC stands for Texas Refinery Corporation and they are located in Ft.Worth, Tx. It is a privately held company with apparently world class products. You can order their products over the phone.
