All,
The latest results in the continuing series...This time using a Purolator Pure One P20195 filter. First the results, then my commentary...
Based on this one test it doesn't appear that the Purolator Pure One is any better than the Mobil 1 filters, or the Amsoil filters. Admittedly, a lot more data would be needed to be statistically significant, but this data point is interesting considering this filter's reputation as being so efficient at filtering. For comparison, a VOA of this oil was performed by the same lab with Particle Counts over 1.5 years ago. See those results here. Looks like we still have room for improvement!
Regarding the UOA itself, note the high Flashpoint - I have never seen it this high in a UOA of Mobil 1 5W-30EP - almost equal to the VOA above. Viscosity was a tad high.
A Royal Purple 20-400 has been installed on the vehicle for the next UOA. See you all again in about three months.
