Valvoline 15w40, 76hrs, 97 New Holland Tractor

[TXHunter]

Oil and filter were not changed at the time of sample. Engine hit 76hrs in just over a year.
Thinking of running another 6-12 months and re-sampling. Thoughts?

Oil Analysis Vendor Comments:
Flagged data (Boron) does not indicate an immediate need for maintenance action. Continue to observe the trend and monitor equipment and fluid conditions. Boron is slightly high for this lubricant.

76hrs = 3000-4000 miles. Let it go another year.

Between the very low wear and the excellent condition of oil (like new visc, high tbn, lack of fuel dilution) it looks good for at least another year and probably much more if use and conditions stay similar to the past year.

Thanks for posting.

Was this thing re-powered?

One more year is a no-brainer here.

At the end of next year, just sample it again and see how it's doing. If the progress is as good as this, can likely do more. I would recommend TAN along with TBN once you get into multi-year OCIs.
