I don't use these oils. I do not use Mobil 1 any longer for anything. Pennzoil I have never used. Not in any Alfa engine I have ever had. I only use Factory Selenia Digitek 0W-30 and Motul in my Alfa engines. I also have Ravenol oils which meet the specs. Honestly, too much worry about this and that, having everything line up or they will void the warranty. In all reality, they will never check your oil, even under a failed engine. I have seen a few failed engines, they replace it and move on.
The cling ratio of Motul due to its organic nature of its base petroleum is far superior than any other oil on the market hence reducing dry startup which Mobil1 one is known to be terrible at and equally due to its consistency under load Motul is more stable under load induced heat transfer. The lichen molecules in the oil link better and tighter to create a better field bearer between bearing surfaces. This is why I have used this for years in all my cars, even non-alfa. While others over the years have had failed bearings or piston rings due to using Mobil 1 or Castrol, my engines have all gone on strong. An old 164S of mine just sold in WA, this is an engine I used Motul in. 290K+ miles on it, still running perfectly says the new owner.
Anyway I will always offer Selenia if you want Factory oils. Not Pennzoil or Mobil. Alfa cannot and will not void your warranty using the factory oil that came in the car new. Available for 2.0L and 2.9L (early and late)

Bare in mind, they do not use LSPI (SN PLUS) oils in Europe for Alfa. It's the Above oil. ACEA is coming out soon with an equivalent SN PLUS oil category but Alfa has not changed spec on engines around teh world, except in US.
