Spy, wouldn't it work like a fuel filter? I thought that as the media clogged with particulates, the average size of the particle filtered went down until flow was reduced sufficiently to interfere with operation. Mind you, I'm the guy who changes both oil and all filters on the mfg recommendations, with synthetic no less. But I think I understand the argument and other than a breakdown in the media I'm not sure how a bypass filter not being changed for a long time would be an issue. A diminishing additive package would be a separate issue. In fact, my impression is that Puradyn recommends annual changes in their filter so that the additive package in the filter is replenished. Since I change my oil more frequently, I just buy the filters without the additive package.
Most fuel filters use mechanical surface filtration. And it is true of surface filtration, that the particles are trapped on the surface of the filter, causing the efficiency to increase as it ages. In some industrial filters (not fuel or oil, though) you actually precoat the filter with a known particulate to make it work.
Depth filters use a torturous path to trap the particles inside of the media. They generally have a distributor on the inlet to try and achieve an equal pressure load on the media.
It's been a while since my last Noria course, and more lately I've been focused on water filtration, which adds in electrical charge (zeta potential) as well as mechanical filtration, so once again, I am not an expert.
If you use the terms "surface" and "depth" in a Google search, you can get the gist of the types and difference of mechanical filtration. Just beware of sales pitches.
I liked the Noria courses as they were not affiliated with a lubricant or filter manufacturer.
I generally stay out of filter discussions because of the amazing amount of confirmation and belief bias and opinion, with no empirical data.
Generally speaking, change oil and filters based on measurable condition criteria.
Failing that, change it periodically, and often.
If it's too hard, make it easier.
If it's too expensive, find a new hobby, or anticipate failure.
I am pleased to hear that a fine vessel like yours has a bypass filter. It is the right thing to have for long term reliability.
