Wear is dropping, but Iron is still high, partially due to fuel dilution. From what I've seen, this oil is good, but not great, as I was hoping for it to hold its viscosity better. The Iron is still high and could be better. On the previous report, the insolubles were 0.2% and the Flashpoint was much better, though the Si was higher. The Si is lower this time but is probably due to an air filter that is filtering better as it becomes loaded up with dirt, but the reduce air flow is possibly causing the engine to run rich, causing the fuel dilution that raised the insolubles and lowered the flashpoint and affected the viscosity slightly as well. The oil tested negative for fuel dilution as the fue dilution happened at some point in the drain and was later burnt off.
