Speedoc, there has been a lot of discussion in a number of threads here over the confusion on what exact oils should be used in our Giulia's. You don't specify which model of Giulia you own. I am one who only uses an oil that specifically shows on the bottle the correct Fiat spec, see below. There are only about 5 oils in the US that meet these specs. Just because an oil is 0W-30 or 0W-40 and synthetic doesn't mean it automatically meets the Fiat spec. Over the last year or so members have said to use Mobil 1, Castrol Edge, Amsoil, and various other oils. I even called Castrol USA and they conformed their oil was not specified for our Giulia's. The only oil that seems to be readily available that meets the specs are two Pennzoil Platinum oils, see the two exact Pennzoil oils listed below. They come only in the gray bottle, not yellow, etc. The descriptions, viscosity and container colors of other Pennzoil synthetic are very similar but not the exact same. I was down one bar on my oil level indicator on my 2.0L Giulia after about 1500 miles. I went online and found the Pennzoil Platinum Euro LX 0W-30 at
Advanced Auto Parts/CarQuest. They could have shipped it to me but I opted to pick it up at the local store. Very smooth purchase. I was very careful and started by adding/topping off with only 4 ounces. That brought the oil level back up to 6 bars and has remained there for my current 4k miles. Two of our local Giulia dealer's service/parts say they use Mopar 0W-30, shipped to them by Alfa??? However, I find zero confirmation that this Chrysler oil meets the Fiat spec.
I have PM'd AlfaRomeoCares in late December about this (said they would get back to me but never did), again in March and again a day ago. I still have yet to receive an answer. I am very picky about what oil I put in my wonderful Giulia, especially since I understand the engine tolerances are very tight and thus the thin 0W-30 or 0W-40 viscosity oil. I also have read that given the sensitivity and tight tolerances of the Giulia MultiAir units, it is well worth sticking to the approved grade and use whatever is currently recommended. I sure wish Alfa Romeo would clearly address this oil issue and what specific oils are approved here in the USA and other market.

Other oils in the US include: Shell Helix Ultra ECT... Fuchs Titan GT1 ... BP Formula Elite
Also it seems that a Mopar 0W-30 and maybe Mopar 0W-40 Oils are approved. It would sure be nice to have Alfa verify that what specific Mopar oils are Ok to use. Below I have a photo of the front and back of the oil for the 2.0L Giulia.
