Good idea...I'm really hesitant about approaching shops with questions like that but I should be more aggressive. Supposedly Valvoline buys all the recycled oil Oreilly
Auto Parts collects, for example, but they only purchase at the corporate level and not through smaller companies like mine.
However a lot of folks around here are using waste oil furnaces, and when supply is low I guess even they'll buy it.
As coolant and oils become more expensive, the market for recycling should really open up.
