I really don't think whether an engine is at 5500 RPMs or 8000 RPMs is going to make much of a difference if there are particles in the oil. And how many particles are really in the oil? Remember it does have an oil filter. The filter should certainly trap anything big enough to do damage I would think.

I think most of the wear come from startup anyway when there is no oil flowing.
