re-purposing used oil? Great. Doing much more doesn't seem worth the effort, not when you know the oil is getting recycled properly anyway.

Filtering and re-using diff/gear lube now...that's a good idea. At least if it's not ancient and contaminated with water and whatnot. Filter something that doesn't usually get filtered and put it back in; done. Rather do that than pay $15 a litre for fresh every couple of years when it doesn't need it.
