I got my car back today. So Nissan recommends I change my oil every 3700 miles and use the Ester oil. Oh yea the engine also took my intake out. They replaced that as well. All under warranty. Nissan said they will no longer cover an engine in my car. I have to get more information on that.

Side note
When I first purchased the car used, I had found a Nissan dealer nearby me and tried to get an oil change there. They told me to use Ester oil, but they did not have time to change my oil that day. So I went to another dealer for the oil change. The one I have been going to up until this point. I was told here that I did not need the ester oil. Just use regular or synthetic (synthetic which I have been using) and I will be fine....... 2 engines later....
