Ah... "the good ole days"... we never wasted spent motor oil in the rural South. (EPA would go crazy today!) Every summer the neighbors collectively filled a 55 ga. barrel fitted with a 6 foot wide "sprinkler" pipe. They'd "oil the dirt road" to keep the dust settled. I remember how dirty our bare feet would get walking to "Trantham's Grocery" to get a "dope" and a Moon Pie. It was about three miles, uphill both ways! A quarter's worth of gasoline in a milk jug to mow the yard and a quater for a Cocacola.
