You seem to be confused again in thinking a nominal rating is 1/2 of the measured efficiency of a filter. Nominal ratings of filters are just the average pore size in the media as measured with a micrometer. Due to poor reproducibility, this measurement is pretty much meaningless.quote:Originally posted by Ebolamonkey:
Amsoil is still nominal at 7 microns but here it shows that a nanofiber oil filter is nominal between 0.00 and 0.20 microns. How does that work?
The AMSOIL full flow synthetic nanofiber oil filter will filter some submicron particles for up to 25,000 miles, the AMSOIL synthetic nanofiber bypass filter will filter more up to 60,000 miles, and the AMSOIL synthetic nanofiber air filter will also filter less than 1 micron particles for up to 100,000 miles.
Have you guys not read the Ea synthetic nanofiber filter brochure at http://www.amsoil.com/lit/g2202.pdf ?
