This subject will never go away
We beat it to death again last summer. WHAT I DO is,,,

use after market filters. As a car freak since the '50s, (I was a little kid) I have heard many opinions. It is classical, the older I get, the more opinions. Yes, for the price of a filter, if it makes you feel good, change it. If, for any reason, what YOU HAVE TO DO, is different, do it.I have heard the Yanmar high pressure spiel before. A performance automotive filter is good to 400 psi. I use WIX in all my stuff. I have things like a big block Chevy hotrod, a 4X4 pickup, a 10KW gas generator, a 4X4 diesel tractor, a Porsche (my wifes, yuck!) let me think,, oh yea, a Yanmar 3GM30F. I've had it since '86. Even rebuilt it a while back. The filter location didn't work for me. I found a remote mount at Summit Racing that uses a full size automotive filter. Works great. And because the filter is four times as large as the Yanmar size, it will last four times longer. Yes size does matter.

Now I can use a $4.95 filter through 4 changes. A buck and a quarter per change, the path to financial security! Pretty silly, but it works for me. Oh, If anyone cares, those Yanmar filters for the GMs, ask for a filter for a Mazda GLC at your local auto parts store. (plus several other models)Same one.
