I have noted that there have been a number of oil threads regarding suppliers and specification of oil to be used on the 170hp 1.4 Multiair engine. They all (generally!) seem to agree that you should be using 5w40 acea c3 oil (Selenia K PE seems
to be the accepted OEM option - other oils are available and argued over!)
Having recently purchased my G and reading through the manual (as you do) I came across this on page 247 of the handbook:
(1.4 Turbo MultiAir
SAE 0W-30 ACEA C2 grade totally synthetic
FIAT 9.55535-GS1 classification
SELENIA DIGITEK P.E.
Reference no. F020.B12
The link to the Selenia oils technical data is:
FL SELENIA - Fluids and Lubricants
The technical data notes that the oil is for twin-air engines (not multiair).
The Mito multiair units seem to require Selenia Star PE 5w-40 acea c3
Eh!! what!! This seems significantly different from what all the other threads have stated (even where there are differences of opinion). I have asked at my local dealer (Western Alfa, Perth) and they use 5W40 acea C3 castrol oil that meets the FIAT spec 9.55535-s2.
Does anyone know what is going on? Has the spec changed but the dealers haven't been told?
As the handbook states that the use of the wrong specification oil can invalidate the warranty is everyone who has been using 5w40 out of luck if the multiair unit goes pop?
There seems to be a lot of confusion about oil and I would like to know what everyone else thinks about this!
