Hi all, there's an ongoing argument on an rx7 club that I belong to re

oil filters. Some recommend

only those supplied by Mazda, stating that Fram and others are

insufficient. Others claim that

cheaper filters are ok as long as you do regular oil changes and replace

the filter with each oil

change as opposed to every 2nd change. Any input on this?
        Thanks, Brett.

The Mazda filters are very well made but most airplane builders have to use
a remote oil filter adapter anyway.  I use the HP-1 or equivalent which is
an industrial strength filter.  About 3 times the cost of  auto filters but
you don't have to change them that often.
