The last time I used them was for the same reason, not my car and didn't feel like doing it. Two things happened, they striped the drain plug so oil leaked all over my driveway and the filter had teeth marks from waterpump plyers on it. They tried to tell me it wasn't their fault when I had only just left there 10 minutes prior. They eventually sent someone over to replace the filter, fix the plug and I made them scrub my driveway just because! I now only drive to one of those places to dump my old oil. Oh and for a little poetic justice, one batch I turned into them in my Delo jugs slipped out of the guys hand while carring it by the bay and not only dumped on the top, but the Mexican profanity coming from the well concluded the guy down there got it too! It really does all come around.
