Hi All,
My last UOA had a sudden spike in iron which seems to have dropped back off. Fuel is still high due to my wife's addiction to the remote start (it's been cold here). I also forgot to mention last time that she switched to 87 octane for the winter, which may not be burning completely?

COMMENT: We're pleased to report a solid drop in iron this time around. Sure, the shorter oil change
interval probably helped with that a bit, but there's also been good improvement from a ppm/mile
standpoint, so steel wear really is better than before. Fuel dilution is really the only sticking point in this
report, and 3.0% is a fair amount of fuel. It didn't cause the viscosity to test below grade, though, nor did it
seem to bother the engine's wearing parts. Maybe it's just a fluke and will improve next time. The TBN is
strong, but we'd stay at about 5,000 miles to watch fuel.
