the guy that i posted yesterday with the malibu, his sister got a really messed up oil change from the quick lube at the local WM where she works. Its a 2003 Ford Exporer sport trac, 106k miles, and it holds 5 quarts of oil. He asked me to check it as he said it was really high on the dipstick. She had kept the empty quart containers n the bed, there was 6, i said hmm somethings up as it only holds 5. I proceeded to check it, level was really high, then i drained and measured what came out. 11 quarts i drained along with an OCOD! I can only assume the guy at WM added 6 quarts along with the 5 that was already in there. Filled it up with 5 quarts Supertech 5W30 and a MCFL820S and sent her on her way. Another reason to never get your oil changed at WM. Just thought I'd share.
