328 OIL

My old 328 started to leak a little bit after I changed to the Mobil 1 15w50 syn but it was certainly not a worrying amount.

 

I switched to Mobil 1 15-50 from dino oil. Interestingly with dino oil it leaked a little oil. Now with Mobil 1 it does not leak a drop. This is contrary to what I expected.

 

No problem.

 

Agreed.....definitely not a problem.

 

The 328 came from the factory with synthetic oil, specifically Agip SINT2000. In fact, Agip SINT2000 should be specified in the OM as well as on a plate inside the engine compartment. You should note that "sint" is Italian for synthetic.

 

Factory oil is Agip 10W-40 SInt 2000 which is a semi sythetic it is bleneded with mineral based oil

 

dhs9, how do you know Agip's SINT2000 is semi rather than full synthetic? I have several bottles of Agip SINT2000 10w40 and no where on the bottle does is indicate it is less than full synthetic.

 

Here is the link from American Agip:

It is semi synthetic.
Also, it is only the older SJ instead of SL API rating and it is CF instead of the later CH and CI ratings. I would say it is obsolete in a way. It has certainly been surpassed by many modern oils. People keep referring to older owners manuals for oil specs. Better oils are now out. Use them.

Please do your homework.
Search the Fchat & the 'Old FerrariChat Archives' for OIL in the subject. There are a dozen or so threads, each with 50 to 100 posts. Some of them by petrochem engineers.

I think you'll find more detail than you ever wanted to know about oil & 3x8s.
