AutoZone/Auto parts store... never thought of that. I stopped doing oil changes on my truck a long time ago, after finding a fairly reliable lube-in-a-box. I'll check around locally to see what's available. Come to think of it, I think I saw a haz liquid waste drop off area at the dump, uh, waste transfer station. The waste oil furnace sounds promising, tho I don't know anything about them. I'll do a search and do some studying on them.
Thanks for the tips.
