I dropped my car off at the dealership for an oil change, tire rotation and to change out the cracked window trims (warranty). When I dropped the car off I explained that they didn't have mobil 1 synthetic so I had 7 quarts of oil on the pasenger side floor board for them to put in the car. He said OK and when I picked up the car I ask the casheir if I was being charged for the oil and she said no it says you supplied it and you were only charged labor and for a filter. When We got to were we were eating lunch my wife ask why the oil container were still in the car. I said they most likely just gave them to us to show that they had put the good oil in instead of takeing it home with them. When I picked one container up it was full. All of the oil was still in all of them. We went back and ask what they had put in the car. He checked with the oil change guy and he said just conventional oil. I said NO I don't use that and they said they would drain it and put my oil in. I told them that I didn't want what was in the filter in there and they said we'll dump the filter out and I said it better not leak when you put it back on. Luckly he messed up the filter taking it off and had to put another new one on. You would think a dealership would be able to follow simple instructions but I guess not.
