I sure do change my own oil. Then I dump the used oil on the weeds in my yard. Kills 'em fairly well too.
Well.......maybe I don't really pour it on the weeds. I do change it myself though. It is a 45 minute drive to the nearest "SuperQuickJiffyWechangefor 19.96" location. Since I can do the job in just over 10 minutes while enjoying a cold beer, for USD $13.00, why would I do otherwise.
