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. ;-) TIA

6000ml/6months whichever is the sooner. more modern diesels are
12000ml/12months.

Are you sure?

I am sure my 54 reg van has the oil change at around 30000 miles. I cannot
find the handbook at the moment to check that. Not that I need it as there
is a light comes on the dash to tell me to swap the oil and this is based on
the type and style of driving that I do.

I wouldn't claim to be an expert but when service intervals started
increasing for petrol cars in the 90's, diesels stuck at 6000/6months
meaning (at the time, whilst fuel costs were lower for diesel) , the
increased servicing costs meant that diesels were only worthwhile if the
extended engine life was brought into the sums.
The diesel manufacturers responded and extended to 12k/12m which is the
case for my 54 plate ford diesel car.
I've not come across vehicles offering 30k miles servicing but now I
have bought my car, I've not continued to look at service intervals for
other makes.

As another poster mentioned, the makers recommendations are likely to be
correct.
