   If it were a high-mileage engine (which it isn't), 30 weight engine oil   
   wouldn't do any harm. But it's a newly rebuilt engine, supposedly with   
   tight clearances as engines are inclined to be these days, 30 weight oil   
   might be detrimental to bearings on cold startup days as well.
