Idea for an Oil Change Cartridge

How about an oil change cartridge that consists of both oil and filter in one package?  This could be a bolt- or screw-on device.  Once installed, the user could replace the oil/filter cartridge in one step and recycle the whole deal – similar to printer toner cartridges.  
It would be nice to have this cartridge out in the open in the engine compartment for easy replacement.
Possible Start Building Blocks –

• Existing concepts for vehicle oil filters, house water filters, industrial cartridge filters, etc.


• USPTO Class/Subclasses for "How-To" ideas – 210/450, 185/1.5, 210/136
