Oil was changed at time of sample, although looks like it could have gone longer.

Blackstone Comments:
This is the same oil as last time, just with more use. As you can see, wear metals didn't bump up a whole lot since last time, so there's no sign of poorly wearing parts or mechanical issues for your Allison 1000. The viscosity was correct, and no coolant or moisture showed up. The TAN shows litle acidity at 2.1. Try 80K miles on the next fill and check back periodically to make sure everything remains in great shape. Excellent report!
