I last changed the engine oil filter in my Mitsubishi 2.8 turbo deisel,

What is the effect of *never* changing the oild filter? Does the filter
eventually clog up, or what?

As for oil changes, there is a slight leak in the rocker box gasket, so the
occasional oil top-ups amount to a complete oil change about every 2 years,
without needing to undo the sump nut - very convenient. ;-)

All filters block up eventually. In most cars, a bypass them opens
but this allows unfiltered oil to go round the engine.

The long molecules in oil get chopped up and the lubricating
properties are reduced.
Also metal fragmetnts, carbon and acids build up in the oil if
unchanged.

Not clever what you are doing.
