There shouldn't be a problem as long as your temperatures stay within the limits set by the Pilot's Notes - trouble is now the Merlins overheat far too quickly.

Engine damage in seconds from lubrication starvation, in a Merlin or any other engine. Bearing coatings burns away, piston's are scored...would be nice to have engine proper use pilot notes posted. Many here push well beyond manufacturer use recommendations, that I'm sure of
