My car is a 2008. I bought it with 6200 miles on it and it was serviced with oil change at 4600 miles. I don't know when it should be serviced even now or where it would tell me. When should the first service have been done? I'm asking as the dash shows a (1) wrench and -65 by it. I also have a window sticker saying next oil change at 11000 miles and 5w 30 oil in the car. This oil change was done by an Infinity dealer that took the car in at 4600 miles for a trade on a Porch. Maybe Infinity doesn't know how to clear the wrench thingy. Maybe the wrench thing wasn't set at its original oil change at 4600 miles by Infinity. The car at present has 6400 miles on it. Maybe the first oil change was to be at around 7000 miles and the wrench is showing its close to that. Any opinions or suggestions. Thanks Ron
