Further to the "correct" specification oil for the 125kW Multiair engine, the owners manual says Selenia Abarth 5W-40 (product code 1390), one dealer uses Selenia K P.E Multiair (product code 1411) another dealer uses Selenia Abarth 10W-50 (product code 1313)! 

Just curious as to what oil others have been "reccomended" to use in this engine by a dealers service department / spare parts department?

Id check with a reputable indie (like Bazz) to see if you really need one.... if so, here >> https://www.shop4parts.co.uk/?name=store&op=Details&ProdID=13831&sku=253886

You can probably use the AlfaOwner 10% discount code
Delivery is usually 3-4 days ex UK (to Brisbane)
Send them your VIN and they can confirm fitment with ePer
I use these guys pretty much exclusively for my late model Alfas
If its not listed and you have an OE part number they will get it from Alfa

No association with the vendor, have used them since 2007

Hi Craig,

Dont need an actuator!!  Just some feedback on what Selenia oil others have been advised to use or are using in their 1.4 Multair.

Sorry for the confusion.

Ok, the reason there is so much confusion here on this issue is that the oil spec has changed since the Multiair unit was released.

If you look at early Giulietta Owners Manuals (2011) they gave just two oil specs, one for all Petrol engines (1.4T/1.4MA Turbo/1.75TBi) & one for Diesels

All Petrol engines were - SAE 5W-40 ACEA C3 /API SN grade totally synthetic lubricant - SELENIA StAR P.E.

All Diesels engines were - SAE 5W-30 grade totally synthetic lubricant - SELENIA WR P.E.



In current Owners Manuals (2018) the specs have changed. The oils are as follows-

1.4T - SAE 5W-40 ACEA C3 /API SN grade totally synthetic lubricant - SELENIA StAR P.E.

1.4MA - SAE 0W30 ACEA C2 /API SN grade totally synthetic lubricant - SELENIA DIGITEK P.E.

1.75TBi - SAE 5W-40 ACEA C3 /API SN grade totally synthetic lubricant - SELENIA SPORT POWER

Diesels - SAE 0W-30 ACEA C2 /API SN grade totally synthetic lubricant - SELENIA WR FORWARD

Many places have not realized the update and are using what they have always used, some have caught on, thus the confusion.
Just one point, you DO NOT have to use only SELENIA OIL, but you do have to use the CORRECT oil, whether it be Penrite, Selenia or what ever.

As for why the changes, the MA units have very fine, high pressure oil galleries that operate the inlet valves, blockages in these are what usually cause MA Unit failures. The oil spec change was most likely done to help prevent this.

As for the diesels, the change was likely due to lower ash oils coming onto the market and changing to these result in less problems with clogged up engines with EGR Valves & DPF Filters.

I hope this helps you in some way to understand whats what with the oils.

As the old add used to say - "Oils ain't Oils Sol!"  ;)

Both the Selenia Abarth 5W-40 & Selenia K P.E Multiair 5W-40 are the original spec, using the Selenia Abarth 10W-50 will completely FUBAR a MultiAir Unit !!!   :o (That's just my personal opinion for what it's worth.)

Just one last thing, though the engines are the same (they are already built and stuck under the hood of the car), oil technology marches on and improves, and manufacturers will recommend the most up to date oils & products.

It's not that the older spec oils are no good for the engine, there are just now newer and better options now available that weren't in existence at the time your engine was built several/many years ago. :)

Just remember the 2.0 Twinspark in 156s were originally spec'd with 10w40, when the exact same engine was put in the 147 it was changed to 10w60, because it was a better oil for that engine, the engine didn't change, oil technology did.
