I've had 5 oil analysis's done on my engine. The first three by one vendor and the last two by a different vendor. (Lab one).
On the first three there were no reports of phosphorous, but on the last two, they were 15 and 20 respectively. The oil has always been x/c 20/50 since break in.
All five have been deemed to be "normal".
The lack of a phosphorous report on the first three could just be that the first lab doesn't scan for that.
I'm just curious if any of the brain trust might know how phosphorous finds its way into the oil and what it is a sign of if it gets a high reading. Thanks in advance.
