Where I live, service stations, car dealerships, Wal-Marts, any store

know what options exist where you are, but I'm guessing there are
options.

I've heard that one shouldn't dump used aviation oil at these
locatations because they cannot deal with the lead.


I see no reason to tell them that it is aviation oil. Think about it. You
are dumping you 7 or 8 Qts into a X00 gallon tank that is in turn going to
be dumped into a X000 gallon tank that is going into a God knows how big
re-refining system. How many PPM of lead do you think there is going to be
at that last stage?
