When I drain oil from a diesel I still want to see a glimmer of gold colour and not just jet black, this works for me.
If it has worked for you then its great, just not for me.

Still a perfect how to for anyone.

Actually I didn't say not change it I simply remarked on what happens in a filter as it ages.---
