[DML] changing to synthetic oil

["captain_hydrogen" <captainhydrogen@xxxxxxx>]

[MODERATOR'S NOTE: The debate on preferred motor oil comes up often and this will not be one of those debates. This is not a question about what the best motor oil is and responses of that form will be dumped as being repetitive with the massive archive we have on oil.]

I will be changing to Mobil 1 Synthetic next weekend and would like 
some opinions or factual information concerning something the guy at 
the auto store said.  I told him that prior to buying my DeLorean, it 
sat dormant for a few years with all fluids present.  He said that 
over time, sediment can gather in the bottom of the oil pan and other 
places and when changing over to synthetic oil, the smaller molecules 
of the synthetic medium can loosen the old sediment and 
cause "chunks" of congealed oil to clog the passage ways.  He 
suggested that I use a motor flush prior to changing oil and pointed 
me to the motor flush section.  He said that anyone will work, but 
pointed to one he had experience with, "Fast Motor Flush, 5-Minute 
Engine Cleaner, by CRC (www.crcindustries.com, part #05336)".  I 
bought two cans because of the amount of oil used in the engine.  If 
I need it, I have it, if I don't need it, I can return it.

The question is, do I need it, or did I buy two cans of "snake oil"?  
Is what the auto store guy said true?  Since I will be changing over 
to synthetic oil, is it possible that not using a motor flush prior 
to the change, can damage my engine?

Looking for answers and clarity.

Thank you,
