- having working in servicing trucks, there's a lot more checks & greasing that are done as part of the oil change -so it still needs a service.
- Cant be good for emissions almost certainly illegal.

1. Yeah, not sure how it was done in practice, maybe a separate reservoir that fed clean oil in at the same rate. Keep in mind that using service trucks, its easy to top UP fluids and oils, as opposed to draining.
2. I imagine it was taken from the clean side of the oil filters
3. Oil Filters generally changed half as often, and could be extended by doubling up
4. scheduled maintenance still required, but less often than oil change
5. in a diesel engine, I doubt it would make significant difference to emissions. Petrol engine would be much harder I'd imagine
