How oftem do you change your oil?
purchased my vette in october and now the weather is changing I have just had the oil changed. My question is how often do I need to change my oil every 3000 miles or longer? or if I do not reach the mileage due to this not being my daily driver can the car set and not worry about it. First car that I put synthetic in and was just wondering.

I was changing my oil at about 4,500 miles, but my oil analysis shows above average lead wear, so I am planning to start changing the oil at least every 6 months.
Also I am not sure Mobil 1 quality is what it used to be, so I am going to try Valvoline Synpower which claims 9X better wear protection than Mobil 1.

GM says use the OLM to determine when to change oil unless you drive in a dusty environment or at least once per year or every 15K miles. There are people who will tell you the OLM monitor shouldn't be followed but they really don't know what they are talking about. It works great and I use it on all 3 of my GM vehicles. We aren't driving 1960's cars anymore.
I drive my Z about 4K miles per year with at least 1K on the track running at WOT with oil temps of 260 degrees for 30 minutes at a time. I run a quart over the full mark when on the track (GM recommended). Changing the oil each December the OLM indicates about 37% and the oil analysis I have done shows no unusual wear. In fact it is better than a lot of other cars that don't get run as hard. If you don't beat your car as hard as I do then you should definitely be able to follow GMs recommendations.
