I'm really puzzled by this recent trend back towards cartridge type filters. The spin on filter was a big convenience step forward when most vehicle mfg. switched over in the 1950s and 60s.
Volvo went back to cartridges around '98 or so, and it looks like many other companies are as well.
The official reason being given is to reduce the amount of waste in landfills.
I suspect that another reason is to further discourage DIY mechanical work. A large portion of the oil sold over the counter is never accounted for on the recyling side of the motor oil equation.
For example, these statistics are sited at the website of the
California Waste Management Board :
"Of the over 1.3 billion gallons of used oils (industrial and lubricating) generated each year in the U.S., less than 60 percent is recycled. "
"Over 20 million gallons of used motor oil is disposed each year in an unknown manner in California by do-it-yourself oil changers. This equates to nearly 1 gallon of DIY used oil improperly disposed of for every adult. "
The other factor sited by the auto mfg. is that it is seen as environmentally wasteful to throw away the steel outer shell with every oil change. I suppose that when oil filters are properly recyled this steel is recyled, but why use it at all is their thinking.
Convenience wise cartridges are a big step backwards, but I reluctantly admit that they are likely to have some environmental advantages.
Expect more and more cars to go this way over time.
As to the cost, new form factors of automotive filters always carry a premium price when first introduced. I recall buying a 1987 Ford Taurus new and being shocked that a replacement air filter for it cost 3x more than a filter for my '82 VW Scirocco it replaced. Five years later the Taurus filter was plenty cheap.
New cars are serviced mostly at new car dealerships, so it takes quite a while for the aftermarket volume to build up and prices to come down. Basic economics in action.
