"We found a lot of fuel in the previous sample from this LTD, but that cleared up nicely this time; the flashpoint was high enough to show no significant fuel dilution. It's a bit surprising, then, that the viscosity stayed as low as it did in this report, since we thought last time that the fuel dilution was the most likely cause for the lower viscosity. This sample also saw an increase in iron, showing more wear at steel parts, although at least lead (from bearings) didn't go any higher. All in all, no real improvements, but not
that much worse either. Check back next oil."
