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.

    Thanks Tracy, I'd forgotten about your remote filter set-up. I'm

guessing that these filters will not screw into the stock filter mount or
match the seal diameter.(?)  This would maybe be of interest to those poor
ground-bound souls who only travel in two dimensions instead of three. If
this mod can be done in a plane there's no reason it can't be done with an
rx7. What is the cost of this mod?
