Yeah, I have a neighbour who used to do that back when restaurants had to pay someone to take their used oil away. He would take it for free and everyone was happy. It’s now recognised as a recyclable commodity now though, and commercial operators pay to take away the oil.
He had a machine in his garage that did the full biodiesel conversion for him. That’s not just filtering - there’s a chemical process as well. It can be fiddly to learn but if you do it, you can use it in a wider range of vehicles and often at 100% bio as well.
