Old technology.... again

Was looking for information on sealing action of oil filter gaskets and found this (Cummins newsletter, Aug 2007):

In the late
1980's European original equipment manufacturers
began reverting back to the cartridge style oil filter. We
see this same trend beginning to appear in our North
American produced vehicles.
This change from a spin-on filter to the new cartridge
filter offers several advantages. The first and most
obvious is filter disposal. The disposal cost of a cartridge
filter is far less than that of a spin-on filter. This
is also an attempt by the individual OE manufacturers
to establish standardized oil filter cartridge sizes,
thereby eliminating the number of different part numbers
required to service a particular brand of vehicle.
The new cartridge filter housing will also be located
on the top or side of the engine compartment making
them accessible from above without the need to raise
the vehicle.

Makes sense to me! Environmentally, since there is less waste with cartridge filters; without a throwaway steel "can", they should cost less from a manufacturing standpoint - and leave less of a carbon footprint.

My 2005 Ecotec 2.2 L Chevy Cavalier has a simple cartridge filter that is accessed from under the hood. It fits into a "well" and has a plastic-composite cover that has an O-ring seal. It is very clean and simple to change.

Doghead, that must be a mistake made by the manufacturer. Something easy to work on??? I guess they overlooked that fact.

As soon as they realize that, they will fire the engineer responsible.

As for them reverting back to the canister type filter: What goes around comes around.
