Find out what oil the engine builder used to break it in and check it with. That is normally a safe way to go. For racing I use Rotella 15/40 in one car and Mobil Super sync 15/50 in the other as that is what the engine builders used and I haven't had a problem. But there are a lot of good oils out there and how you plan the car can be used in determining which one you chose.
