I changed my oil Friday. I loaned my oil changer to a friend of my dads, and he returned it in a trash bag. I just assumed the trash bag was to keep his car clean. I opened the trash bag and the changer looked like I just pulled it out of a 55 gal drum of used diesel oil ! If I could have got my hands on that guy... If I were going to borrow something from someone it will be returned cleaner than when I got it.
