It was mentioned earlier that Champion Labs manufacturers Toyota, Mobile1 and others. I don't know that to be a fact but it wouldn't surprise me a bit. I would also think WIX has some of this business as well. Both these plants make a large variety of oil filter brands. Between the 2 they likely hold 95% or more of the filter business in North America. I've sold both plants socket screws which they go through like water, being a high speed stamping plant.
As far as this meaning all the mentioned brands are alike? I wouldn't be on it. Some, like Mobile1 have the reputation that allows them to charge more. That doesn't necessarily equate to a better product. Some brands go after the price market. Each brand can and do specify their own specs which allow or dictate a lower or higher selling price.
Now, if you really want to obtain far superior filtration in the neighborhood of 100K miles between oil changes. (that wasn't a typo) There's several companies that mfg. an add on filter that removes un-burnt fuel, water and solids down to 1micron. These are the things that naturally get into your oil and cause frequent changes. One such company is called Petrosavers out of New Orleans. Their element, at least at the time I sold their product was made from highly refined cotton. Looked close to a spool of thread or yarn and dropped into a coffee can so to speak.
If you went with this type of system I'd recommend changing the pass through filter every 20 or 30K miles. I'm thinking they'd degrade at some length of time, but can't prove it. If you're using oil, every time you add a quart you're also bringing up to spec the additive package. If you're not using oil I guess I'd drop a quart or so when you change your filter, then top it off.
These filters are used a lot in truck fleet operations, marine shipping & tug boats, as well as railroads. But they do offer small units appropriate for passenger cars.
