No. Not at all.

Certain sorts of additives that ancient engines, designed based   
depend on have been reduced.  It's a non issue for modern engines,  
which are largely designed around modern lubricants. Even in the case  
of old-fashioned engines designed around in sufficent lubricants, oil  
analysis will tell you when you've left your oil too long.
