I won't bother repeating Blackstone's comments. Basically, they said "normal." My own interpretation is that, once again, it's been shown that moderately long time intervals have little to no effect on oils in an engine that gets a reasonable operational cycle. This tractor is only used when hard work is needed and then it's used for hours on end. Otherwise it's parked. The fuel trace is probably due to my warming it up with light work before changing the oil and taking the sample.
You will notice that the oil thickened considerably, which is a sign of soot buildup as evidenced by the 0.4 insolubles. This oil is doing a good job of keeping that soot suspended... a plus for CJ-4 oils in general. The 9.3 TBN is amazing to me. This is the longest run, both in time and hours, I've made with this engine. I think as it stands, considering the soot and insolubles, 126 hours was a skosh higher than ideal (calls for 100 hours in the manual) but well inside the "envelope." Considering the number of hours this engine has (the equivalent of over 500,000 road miles), it's a great report. I wish the rest of the tractor was holding up as well as the engine ( : < ). The last quart of added oil was installed at the beginning of this season in May and it was due for another when I changed it.
If I don't trade this old timer in next year, which is not not likely, it will get a bypass system and I be posting again in another three years. If interested, I believe there are two other reports on this engine posted.. just look up my posts.
