I've done the same thing with my kids, young (5?) and when older - 12+

I use an old dishpan. I did two oil changes today with it, poured old oil back into jugs it came out of. I'll take them to walmart sometime in the near future.

If I have a lot of oil - 5 or more jugs, I will make a trip out to Mesa oil on highway 72? - they have a self serve recycle container. (or used to anyway, been a while since I've had that much to donate)

Mobile 1 synthetic and napa gold filters. About the best you can do I believe. (don't use fram filters!)
