Just got my UOA back on my first run of the $1/quart Autozone Castrol SynBlend special. This run was for only 2,434 miles, the reason being 80% of my trips are < 5 miles and so the oil had been in there for more than 6 months already. My next run with this oil will probably be for closer to 5k miles.
Honda A01 oil filter was used. The car has just under 145,000 miles on it.
I don't believe Castrol SynBlend contains moly, so the 47 ppm moly is most likely from my last run with PYB 5W-20.
Is the low flashpoint a point of concern? What would cause the flashpoint to drop to 360?
