Blackstone Comments:
The lead increase caught our eye last time, which is why we're so pleased to see it drop to 2 ppm here. This level is what we're used to seeing from your Duramax and it perfectly matches universal averages. The increase last time wasn't
dramatic by any means, but we'll take lower wear any time. This was a shorter run too, so that may have helped some, but iron is the metal that tracks most directly with miles on the oil rather than lead. No excess fuel or coolant showed
up in this 15W/40 oil. Keep this oil in use and just check back in 5,000 miles or so.
22K sample on 6.13 was done through Oil Analyzers Inc, everything else is through Blackstone.
