Hello,

I took the plunge and purchased a 500x recently, she’s a beaut.

It was first serviced a year after being on the road. Including a full oil change, it had done 16k miles.

I understand people and fiat say it’s 9k miles to an oil change or 12 months however looking at my service schedule book. It states a service each year, for which an oil change is recommended at 9k miles but not mandatory until the next service at 18k.

Any one agree with this?

Thanks
 
As the MultiAir unit heavily depends on the right amount, clean, quality oil with the right specs, ( Euro 5: 5W40 C3, Euro 6: 0W30 C2, both synthetic), and a substantial amount of units fail over time ( VERY expensive...!!) it's recomended to change oil and filter every 6500 mls, OR once a year, whatever comes first, not regarding what the handbook says.
At about 35000mls, the small MultiAir strainer/filter should be changed as well, often overlooked....
 
For my 2015 1.4 petrol which has been serviced by the main dealer from new it’s 1st service at 9000m or 12 months just checks no oil change then 18000 major service with oil change then further 9000m no oil change then another major service with oil change then further 9000m and so on.
 
Cameron, I would get the oil changed at least every 9000 miles or annually, ensuring the correct oil (Petronus Selenia Digitek) is used. It's an inexpensive way of minimising the chance of premature engine problems.

When your engine reaches about 40.000 mls with this oil schedule, the MultiAir unit is at risk, and you're out of warranty....
Good luck...
Do a google search to find out how many fail at about that milage.
Search for Dodge Dart as well, as it uses the excact same engine...
 
MultiAir filter:

That according to Fiat/Alfa is described as a PLUG.

Same plug is used on non MultiAir engines dating from 2008 onwards.

By the looks of it looks more like a pressure/flow regulator than a filter/strainer, especially when you see the size of the apertures.

Might get a little mucky but there would probably have to be significant oil contamination, emulsification etc. for any serious block edges to occur (unless there is only a small hole in the end of the tube that is not visible).

So where is this filter used in a non MultiAir engine..??
 
Can't figure out how to get a PDF file attached but here is the text.

Note the old Bravo 2010 and on the ePER view the PLUG is show as being under the rocket cover going into the top of the cylinder head.

Well it still is the one and only MultiAir filter, probably the 2010 Fiat 1,4 had this device already?
Anyway, it's not in the regular maintenace schedule, so often overlooked at a major service, but you can see in the picture above how dirty it can and will be, after a certain time and distance..

After a closer read, the above specs you supplied are for a MultiAir engine indeed.

Sorry Peter but, in part, you are wrong.

The earliest use of this "plug" was in the:

X6 Alfa Mito 2008-2011 CC1.4 CMBZ KW77

To my knowledge there was not a 1.4, 77kW MultiAir engine in 2008, but that is not the deciding factor. When I look at the parts list (specifically for this part) I can not see the UniAir/MultiAir actuator assembly listed or shown in any slides/pictures.

I could be wrong, but then only by what Fiat document.

Fiat document on my version of ePER V68:

(FIAT) - 81 NUOVA PUNTO ABARTH MY2012 (2012-....)
(FIAT) - 4B PUNTO EVO ABARTH (2010-2012)
(FIAT) - 3Y NUOVA BRAVO MY 2010 (2010-....)
(FIAT) - 51 NUOVA PUNTO MY2012 (2012-....)
(FIAT) - 3J PUNTO EVO (2009-2011)
(ALFAROMEO) - QZ MITO MY2011 (2011-....)
(ALFAROMEO) - X7 GIULIETTA (2010-....)
(ALFAROMEO) - X6 ALFA MITO (2008-2011)

Regardless of anything else Fiat call this a PLUG and a plug it is not as plugs don't have holes in them unless the plug is a specific "direction diverter or regulator" of some type.

I think what is actually required here is not an A) me vs B) you but actually more technical detail and analysis of this "plug's" real design function.

I assume nothing, and try to check all my facts before posting. Nobody is always 100% right and this may be a case in example for you, me or both of us.

What I do appreciate is that you have highlighted this "plug's" possible relevance to MultiAir health at higher mileages.

We need to dig deeper into this.

Peter, you have raised a very interesting issue. It's puzzling that I can't find the part at Shop4parts, unless it's hidden somewhere.
How often would you advocate replacement? It seems to be located under the cambelt cover, so changing it when a cambelt/tensioner/waterpump change is carried out.
What tool is needed for removal, a hexagonal key?
If it isn't too dirty, could it be re-installed? It looks like the thread is pre-loaded with threadlock.
My car is going in for a major service shortly (20,000 miles), I will see if the dealer has any idea that this part needs changing periodically. My bet is the service desk will have no idea what I am talking about....
 
Hexagonal key indeed.
It's easy to change, no need to take anything of but the engine cover.
It's suggested to change it anywhere between 30.000-40.000 mls, and yes indeed, many workshops haven't heard about this filter, if so, I would stay away from them....
About re-installing, maybe it's possible, but I would fit a new one, just for peace of mind, and they are not that expensive...
