Hi guys, can anyone tell me what oil I need to use in my multiair sporting 135?

I'm just after a top up bottle 1l can anyone point me in the cheapest direction?

there is someone on ebay selling some clearance saab/ alfa/ fiat selenia 5w40 stuff part number 14111616

is this correct?

I can't confirm if the part number provided correlates to any Fiat item.

All i can say is that it's got to be ACEA C3, 5W-40.

There's a good chance you'll ruin the multi air unit if the wrong oil is used.
