I ran Royal Purple for one change and sent it off to Blackstone for an
analysis. The results were not good. All of my wear materials were much
higher than average. Silicon (dirt) was still below average so I know it's
not an air intake problem. This was with 4500 miles on the oil. Before this
sample, my oil has always come back with below average contaminant levels.I
have another sample of Mobil 1 with them right now that I'm awaiting the
results on. If the contaminants are back to normal, then I'll have my own
opinions on the Royal Purple motor oil. If the levels continue to be high,
I'll be looking at saving for an engine rebuild. I'll post the results as
soon as I have them.
just my .02
