Exactly. I have to take my used oils to the landfill where they have a collection tank. Some company comes and sucks it out periodically. They also collect from the shops. The used should go to a refinery and be added to its feed stocks to do it properly. Higher costs undoubtedly, but part of cleaning up.
All this EV noise is mostly smoke and mirrors added to road apples. Converting to natural gas at least as a cleaner burning option for now would be better. There is a trial program here in Alberta with one truck fleet running diesels converted to run on natural gas and a number of fuel depots for them. No pig piss exhaust treatment required either.
