Ok, as far as I know thin oil gets too "watery" on high temperature. Warming up is one thing, but the oil must provide the proper viscosity during the rest of the time. With thin oil, it's possible that metal to metal contact occurs at these sport engines.
This is what I've heard.
I've searched the net a bit, and now I see what fvillota was saying
Everyone argues about this thin or thick oil issue, and I don't want to start an arguing here as well. Peace
Maybe it depends on which climate we are living in.
