I'd rather use the 15,000 severe miles to 25,000 normal mile up to 1 year AMSOIL filter than the 3,000 to 7,500 mile Purolator PureOne filter or the 15,000 normal mile (only if out of factory warranty) Mobil 1 filter.
People should buy based on getting their money's worth out of a filter. PureOne is a pretty good value. Not many people do the mileage in one year to justify an EaO.
Now a PureOne is a waste over a $3 filter if you're a 3k/3m type ..or even a 6month/6k type unless you're willing to use the filter for one year and change the oil at six months. The lower the mileage, the less sense it makes to use an expensive filter.
Insolubles ..combustion byproducts are what loads a filter. It's not chunks of metal, at least other than the random bigger chunks. The loading depends on the cold starts and fuel enrichment. Longer daily drivers don't produce a proportionate amount of insoluble material on average. The out of enrichment miles are mostly hollow.
