Could you scan and show us on of those reports? It would show up in the viscosity reading....unless somehow that action Jon described is reversible...
no - i've been out of the company for 4 years and out of the Army for 3 years.
basically, the sample goes to the lab (gov contracted civies) and a report is generated back. nobody ever paid attention to the specifics, just the instructions, i.e.:
- silicon (dirt) in oil - check air filter/housing, change oil and resubmit sample
- coolant in oil - repair, change oil and resubmit sample
- fuel in oil - repair, change oil and resubmit sample
- high metal content - replace engine
- change oil and resubmit sample
- normal results, no action required
so even if everything else was hunky-dory, they wouldn't change the oil until the report said to. i would have to
assume that the
basic pinciples of oil shear were a part of that test and would be caught.
