For many do-it-yourselfers, changing their car’s motor oil is a regular task. However, most don’t realize that they can recycle this oil themselves and use if for future oil changes. By using a short length of cotton rope as a filter, you can change quarts of used oil into fresh oil in your own garage in a matter of weeks.

Step 1

Cut the 2×4 to be the same height as one of the gallon bottles.

Step 2

Cut two 10×10 squares out of the wood sheet.

Step 3

Screw the two square boards onto the ends of the 2×4. The end result should be a stand with a flat bottom and a flat top that is about as tall as one of the bottles.
