I'm breaking in the engine with the Nissan Ester Oil (which is non-synthetic btw) and will continue using it until 15000 mi. After that I'll use a heavily ester based synthetic oil.
The reason being; this engine likes the abundance of esters but likes conventional oil to allow full break-in. Synthetic might do its job too well and inhibit the "break-in wear" that needs to happen.
