All contacts and work were performed with professionalism and courtesy. Only problem was that they changed my oil without consulting me and replaced my Schaffer's synthetic oil with regular oil. I had just changed my oil so all that new synthetic protection is gone. I am not upset about the need to change the oil, I just feel I should have been notified, so I could have them replace it with synthetic. I would have paid for the synthetic oil change. They did not charge me for the oil change due to this oversight.
