Below is the response I got from Amsoil. I don't know what to think but will run it on up to it's change time probably and then run my last BE-100 and see what that one does. Maybe it was just a fluke but that doesn't explain what Steved is seeing so I don't know.
Thank you for contacting AMSOIL with your concerns.
In response to your inquiry, I had an opportunity to review your oil analysis results with our Oil Analyzers personnel. The following are a several explanations for the very slight increase in reportable soot/solids level:
1. The overall soot/solid level is extremely low and barely within the detection limits of the analytical equipment. Any minor variation in the sample, sample preparation, and external contaminant can skew the results.
2. Any variation in driving conditions, habits, fuel, air filter performance can change the overall soot/solids trends, especially at these low soot/solids values.
3. The number of hours/miles on the engine is increasing, thus increasing the potential of the engine not performing at optimal levels.
Through testing at Southwest Research Institute and Milwaukee School of Engineering the efficiency of the EaBP filter exceeds that of the BE series filter. The EaBP efficiency was determined to be 98. 7% efficient at 2 microns, with time weighted average soot removal of 39%. The BE filter was determined to be 93% efficient at 3 microns.
Thank you again for the opportunity to respond to your concerns. As always, please feel free to contact us again if we can be of further assistance.
Sincerely,
