Sorry to hear that about the FIAT.  Synthetic oil is high in detergents.  So, if a motor has been usine Dino brand all it's life, the Synth will clean it out. Usually cleaned in about 1000 to 1500 miles.  If someone is moving to Synth Oil I would recommend changing the filter after this "cleaning" period.  Sometimes to the detriment of the owner, it will make  tolerance variations show in increased oil consumption.  I usually will only put in synth into a New, rebuilt or 100% sound engine.

Counterpoint:  My 91 V8 w/ 225K has never seen syn oil and, in fact, 
has
suffered whatever dino oil the local discount place had on sale.  
Oil/filter
(Mann's @$8/ea through 1-800-VWPARTS) interval 5K.

It has also never been opened up at ALL.  I fill it to the "full" mark 
on the
dipstick (~10 qts).  Have never had it below the "add" mark before 5K.

IMO/E, the syn is definitely better, but with the huge oil capacity and
superb oil cooling system of our V8s, dino works fine and is more cost
effective. (15K = 20qts @ $1 vs 14qts @ $4--assuming syn burns at about 
the
same rate and is changed at 15K).  But then again, I am that guy that 
has
burned 87 oct for the 120K that I have owned the car, turn my own UFOs, 
fixed
my own Bose,...cheap-cheap-cheap...YMMV!

BTW, I did use syn in my Fiat 124 Spt Cpe from 150K to 250K--then quit 
when
it started burning a qt every 2K.
