Donaldson made an exclusive agreement with AMSOIL to provide this synthetic nanofiber filtration media for automotive, light truck and motorcycle applications.quote:Originally posted by Lamont B Dumont:
So, regarding this wondrous proprietary medium, does Donaldson supply it exclusively to Amsoil, period, or is Amsoil the only automotive marketer? Is Amsoil's exclusively use of this medium based on the fact that no one else finds this medium particularly special for automotive applications? If this stuff is that good, you'd think that Donaldson would have shopped it around to marketers with more market-share so they could sell more of it.
As to why the other oil and filter companies do not make a 25,000 mile synthetic nanofiber filter, you'll have to ask them. My guess is they feel they make more money selling more 3,000 mile filters (PureOnes recommendation) than 25,000 mile filters.
