Re[4]: How Hot is Hot?

Someone correct me if I'm wrong, but the majority of quality oils out on 
the market contain detergents.  Yes, going from a non-detergent to a 
detergent could be detrimental.  But going form a conventional detergent 
oil to a synthetic oil (and all the synthetics I know of contain 
detergents) will NOT cause any problems.  In fact, you can buy oils that 
are a blend of conventional and synthetic, however, it is generally best to 
use a pure synthetic than one diluted with conventional oil.  One important 
item to remember:  NEVER use a synthetic oil to break in an engine unless 
SPECIFICALLY instructed to do so by the engine BUILDER (the new 'Vetts come 
with synthetic oil but I don't know if the engines are broken in with it).  
Breaking in an engine requires some friction that synthetic oil doesn't 
allow.

We've had a good discussion about using synthetic oil in the recent past.
My question is: can you switch to a synthetic oil readily or can you only
use it in an engine that has been rebuilt and run exclusively with it.  I
remeber Muir's cautions about the detergent vs. non-detergent switch and
the damage that can be caused by going in the wrong order.
