Recommended oil filters for Mazda rotary

I have seen an interesting study on oil filters. The comparison

of

all

commercially available

filters were used with interesting results. The high end of oil

filters

was those available from

Amsoil.They were superior in filtration capability but they came

at

price. Of all the available

filters on the market, Fram and Wicks tested the worst with poor

materials and common failure of

parts, like bypass valves. Interesting enough I got the data

from a

rotary enthusiast off of his

web site. It showed for the money that AC-Delco rated highest in

materials and quality for the

money of most availabe filters. Mazda uses superior filters as

well

but

that is usually a dealer

item and will generally pay as much as an amsoil filter. The

remote

set

ups that we use lend

themselves to easy amsoil adaptability. I am partial to the

lubricants

that they produce but I was

not involved in the study. I am just the messenger.

Let me clarify one part of Doug's message. One of the filters that

was

labeled as less well made was from "Wix," not "Wicks," the aircraft

parts

supplier in Highland, IL.

I think the survey to which Doug refers is the same one found at

Lets clear the air on this subject. That study has been around for at
least 4 (or more) years, I remember reading it when I got my FD. Since
then many of the filters have had their design changed or updated. I use
the Fram filters in my FD (94 13Brew tt) based on more recent
information. It does appear to be a very comphrensive study of the
filters which makes it all the more believable.

Don't base any decisions on that old study. Mr. Ciriani (whose site that
is) and I have had direct communications on this and other subjects.
Read that study with a grain of salt and then confirm it elsewhere (like
Consumers Report or some other car mag).
