Allison spin-on filter quality

[Kc5khr]

Is the filter made (sold by) Wix considered an adequate replacement for the Allison transmission?
What about the Wix fuel & oil filters?
Thanks

Truck shop uses nothing else on a fleet of 50 trucks and around 20 pick-m-up trucks. Been several years and they aren't going to change as there is no reason to . For what it's worth.

Thanks IIRC, the only oil filter that returned better results than the Wix was the Baldwin. The Wix fuel filter is a Racor relabeled as Wix just like any other OEM fuel filter. I don't know about the Wix spin on for the Allison. Maybe George M. or others in the know will chime in with more info.

The following info was posted (11/02) in the WIX Oil FIlter (http://forum.thedieselpage.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=3;t=004463) thread.

"I used WIX filters for years. They are excellent filters. However, if you go by the specs, the BALDWIN B1441 is the best one I have found for the Duramax (so far). I sent emails to AC Delco, Baldwin, Wix and AMSOIL requesting filter % efficiency ratings in microns for their DMAX OIL filters. All responded except AMSOIL. Here are the numbers I was quoted.

AC DELCO PF2232: 25 microns nominal, 40 microns absolute (Beta numbers not stated)
WIX 57202 13 micron nominal (50%, Beta =2) and 37 micron absolute (98.7%, Beta = 75)
Baldwin B1441: 8 micron nominal (50%, Beta =2) and 23 micron absolute (98.7%, Beta = 75)
AMSOIL SDF-52: No response - May be identical to B1441 since Baldwin is OEM for AMSOIL"

So far the Baldwin B1441 has the best rating
