oils

[Godfrey DiGiorgi <ramarren@xxxxxxxxxxx>]

Here's a quickie question for y'all. 

'78 Alfa Romeo Spider. SPICA injection. I always have Mobil 1 15w50 on 
hand as I use it in all my motorcycles, and over the course of the last 
3000 miles between oil changes, I would top it up with Mobil 1. It ran 
smoother and cooler that way. 

However, service tells me that he doesn't put synthetic into SPICA cars 
because Alfa Romeo specifically states that it's not compatible with the 
SPICA injection unit. I've got no clue as to why this would be so, 
neither does he, but as he is an Alfa dealer and service specialist, he 
won't use it. 

Anyone have information on this that would let me understand why? Or 
experiences with synthetic oil in SPICA cars?

Thanks!
Godfrey
