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

re

oil filters. Some recommend

only those supplied by Mazda, stating that Fram and others

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?

The oil filter bypass adapter was about $42, the remote filter mount was
$50.  Add to this the cost of the 2 added oil lines (I used AN-10

fittings

& hoses) to hook everything up.  I would recommend that any and all

Mazda

rotary enthusiasts buy a copy of Racing Beat's Catalog and technical

manual.

It is the quickest basic education on the engine you'll ever find.  Also

has

the parts I mentioned above.

    Thanks, Tracy. I'll pass this on.
