Hello all, this is my second oil report from Blackstone running different change intervals. First report was for Rotella Dino, changed at 5k interval. The second report reflects Rotella T Synthetic with a 9k mil oil change interval.

How do they look to you guys?? Also what about the iron readings too high? My soot levels seem to be really low consistent 0.3% each at 5k and at 9kmiles, is it safe to go longer?

Their summary:
BILL: You are looking for more oil use miles and we think you can run them if you want, if you don't
mind seeing iron wear reading quite high in relation to universal average levels. The iron level in
universal averages is based on a 5,652 mile oil use run. You beat averages last sample with the
5,000-mile oil use run, but you can see the effects of the 9,000-mile run on iron in this sample. Watch
lead closely if you choose to run more miles next sample. If the oil gets too abrasive lead, from
bearings will increase. At that point you will have run too many miles.
