I've always used regular conventional oil for first 500 then changed to whatever I want to use from that point on. I'm using valvoline 30w non detergent to break mine in.

Very interesting, since the factory fill on the LT1 Corvette was MOBIL 1 synthetic. I believe they were broken in by the customer.
