I've run Penrite HPR 5w-40 with some success.
That must be for the Diesel Engine.
The MultiAir system is very fussy about oil used. Only in theory *ONLY* SAE 0W-30 ACEA C2 oil.

Ralf you are pretty much on the mark with this but this is also interesting and very specific specific and interesting specification situation. Were my dad still alive (50 years+ off working for Shell and Esso/Exxon in the oil/additive/formulation/.... business) I would be inviting him round for breakfast, lunch, dinner, ....The difference between ACEA C2 and C3 is the HTHS "High Temperature, High Shear" viscosity performance.. or roughly how the oil viscosity hold up with temperature and pressure.
C2 oils have an minimum HTHS viscosity of 2.9 mPascals... while C3 oils have a minimum of 3.5 mPascals. A higher HTHS value means the oil is more resistant to shearing.
If an engine "requires" C2, all that means is that the oil needs to exceed that 2.9mPa threshold... which a C3 oil does.
Newer engine designs are given thinner oil (0W20 is all the rage now) but are expected to run it for 18,000 miles or similar... so C3 was devised. C3 would work in a C2 engine... (which I suppose is where Castrol's "C2/C3" labelling comes from) .. whereas C2 would not be so good for a C3 engine.

https://www.oilspecifications.org/acea.phpAussie probably needs a one-step on the 0 and also on the W30.. UK is cooler, I suppose.
My old beast being a 1.0ltr needs "Petronas Selenia Eco2 0W-20 ACEA C5 9.55535-DM1 or equivalent"... which seems to mean "Petronas Selenia Eco2 0W-20 ACEA C5 9.55535-DM1" since I can hardly find that, never mind an equivalent...

All makes sense to a degree. I've mixed oils with no big bangs yet in conventional engine but I get a little nervous with the TwinAir/MultiAir engines as when then TwinAir first came out there were many (well more than expected) valve unit failures and Fiat made several oil changes ending up with a low C2 HTHS value.I think Shell's combination "C2/C3" must refer to the oil's "SAPS" (Sulphated Ash, Phosphorous and Sulphur) rating.
C2 and C3 are both "mid-SAPS" (0.8% ash) .. so Shell is obviously focusing on SAPS rather than HTHS. SAPS needs to be lower when a vehicle has more DPF and pollution control filters and systems (e.g. AdBlu, etc.) , since sulphur makes a stink and ash blocks DPFs.
Anyhow, in theory, if the SAPS is the same, then any engine that needs C2 will not complain about C3, since a C3 oil meets the requirement of C2 "engines", in that it has an HTHS above the minimum of 2.9mPa*s. I suppose it might depend on what else the C2 oil has in it, that the engine needs, which a C3 oil may not have....
It looks like the league table of oil spec's looks like:
C5 = minimum HTHS Viscosity of 2.6 mPa*s (mid-SAPS)
C1 = minimum HTHS Viscosity of 2.9 mPa*s (low-SAPS)
C2 = minimum HTHS Viscosity of 2.9 mPa*s (mid-SAPS)
C3 = minimum HTHS Viscosity of 3.5 mPa*s (mid-SAPS)
C4 = minimum HTHS Viscosity of 3.5 mPa*s (low-SAPS)
I'd hazard a guess that the C5 oil is just low HTHS/viscosity so that manufacturers can meet emissions and fuel economy specifications.. and in real life, a 0W20 oil is going to work in any engine that needs a 0W20 oil, regardless of the oil's ACEA ratings.
Having said that... I haven't checked but I think all 0W20 oils will be C5 by default, so in any case if you have the one, you will get the other... but I dunno. I'll find out as/when I start doing my own oil changes and research.
I still think (though I won't try it on my brand new engine just yet.. ) that "any" 0W20, as long as it is changed annually or 9000 miles say, will be fine, because ultimately it's just moving metal parts that need "lubrication".. which a clean, good condition 0W20 oil will provide.. even if the ash, HTHS etc. isn't precisely "as certified". Something to look forward to finding out..

The Manual says Selenia SAE 0W30 Acea c2 9.55535-DS1 for diesel engines. I'm using exactly the same oil. Halfords says that 5W30 is not suitable for your engine when I enter the car's plate number. They recommend 3 brands all of them 0W30, The reason I asked here is that I'm confused when people say 5W30?!?!?!I'm not sure what your engine needs (do you have the manual)? But 0W30 sounds a bit "recent" (more recommended for the latest 1.6 which used Adblu).
If you're not sure, I'd go with 5W30, or even 5W40 if the weather stays mild.

I always order selenia from here. No problems at all:With my twinair.. as no Selenia was available..
I found only Opie oils had an online configurator that made sense.
( it recommended a Millers product..which I sourced online)
Have a look and tell us what you find
Petronas now may the Selina brand of oils, so this is the oil that fiat now recommends, if in any doubt look at the side of the can and it will tell you all the standards it complies with on their. Over times the standards can change so something could be a higher standard that a previous standard and so that specific designation will change on the newer oil. Basically if that's what they sent you, it's probably fine to use.Sorry to bump an old thread, but just received service parts from Alfa shop for the 1.4 multiair, and they sent me Petronas Syntium 7000, did we get anywhere on the conclusion if its the same as the digitek, I'm sure they wouldn't sell it if it wasn't but thought I'd ask, my paranoia is setting in, Thanks
