yeah, this oil was 2.5yrs old, but the sample was just taken 2wks ago. possible, too, that this gave a lot of particulates a chance to settle & drop out of solution. levels may have been higher had i taken a sample shortly after failure. regardless, i will dissect this thing this summer.

The older M1 from around 2009 had more moly in it and zinc, thats why i thought this was a modern sample of Royal Purple, I didn't look at the date.
