My first service was complimentary too. But I didn't know about the synthetic oil thing. I looked at the slip and it just says 5W20 oil. I hope they put in the right stuff. I am going to ask them what they put in. I am sort of an oil change freak and since it is the first change, had it done at 3,800. I figure that there are metal parts and such that are an issue with the first oil - - not that I know anything about car engines. But I had a Saturn for 20+ years and always changed the oil every 3,000. That car was as good as new when I sold it this year. Also, change my Honda oil about every 3,000. I have had mechanics say this is the thing to do. Today, I have water under the car and splatters all over under the hood. Haven't had the air on for 2 days. Wonder what this is. Has never happened before even with the air on. I could actually see water dripping out underneath. I am wondering if they overfilled the coolant when serviced, but I had this happen after only driving about 4 miles. Has anyone had this happen. I am talking to my dealer tomorrow.
