Most engine oil is recycled. If you change your own oil, you can dispose of it free at many car parts stores, like O'Reillys, Advance Auto, and Auto Zone. It can be refined into fuel and lubricants.
If gas goes to $15.00/gal.......I will buy another horse.
I will ride it into town every evening at sunset.
I will buy a 6-pak of Corona.......& a bag of Doritos.
Ride home.
Call it a good day & be happy.
