I'm thinking cartridge type oil filters will become more common in the automotive arena future for various reasons (environmental mostly) as opposed to the spin on filter that has dominated the market for many years now. Spin on type filters are pretty straight forward as far as installation and removal. The cartridge filters usually require a little more input/detail from the installer/remover, (O rings, usually at least one, more likely two), that must be contended with as far as proper installation and removal. I'm speaking especially of the folks that do not change their own oil/filter, but rely on various retail outlets to do the job for them, (quick lube places, big box store auto service centers, and the like). In short, I believe it takes a little more attention to detail when it comes to servicing cartridge oil filters, as opposed to spin on type oil filters..... in other words, more room for error during the removal/installation phase by employees of the aforementioned establishments.
