I doubt the value except in very high performance engines. Seems to  
me that auto engineers should be the word on how to maintain the  
engines that they design and oversee the building of. The bearing  
materials and tolerances they use react to lubricants in a tested and  
known manner. Warranties and expectations of longevity are predicated  
on the use of non-synthetic oils. I am unaware of any warranty  
extensions given for use of synthetic oils.
