From Blackstone: "We don't quantify the amount of soot in a sample as part of the standard analysis, but there was enough
soot in this sample to prevent us from obtaining an insolubles reading. Excess soot can show a combustion issue, but
we're not sure if that's the case since that typically comes with a high viscosity as well. Iron is on the high side of
average, showing more steel wear than normal. Other wear metals are in good shape compared to universal averages,
which shows typical wear with oil run ~8,400 miles. The TBN was strong, but run ~4K miles and check back on iron."
Iron: 94
TBN: 7.2
