I had my oil changed here once. When I got home, I noticed that oil was running out from under my truck. Upon investigating, I realized that the plug in the oil pan was left loose, so loose that I really don't know how it didn't fall out. I had to tighten it, clean the oil off of my driveway, and put three quarts of oil in my truck. I'm lucky that it made it home without damaging the engine.
