Been doing my own oil changes since high school (mid 60's). Bought my wife a new 2010 Fusion and got some free oil changes with it. Wasn't going to use them but decided in a moment of insanity to try one. Took it in to the dealer quick lane and they got it done in about 45 minutes. Got the car home and after it cooled down, for 1/2 hour decided to check the oil level. I was shocked to see the oil level was well below the safe zone. It barely showed on the dipstick (about 1/8 of an inch above the bottom tip). I had to add almost 2 quarts to get the oil level in the safe zone. I was livid and called the service manager immediately. He was very apologetic and checked on who worked on my car while I was on hold. He told me it was the quick lane supervisor who did the work and could not understand how it happened. He offered me 3 additional free changes as compensation. I told him that he was nuts if he thought I was going to give his shop 3 more chances to destroy the cars engine.
