To be honest I would have to say I was not confident that this dealers service department was au fait with the TA. I realise it is a new development but that is not an excuse for what happened in my case. When I researched the engine before making the decision to buy I read that Selenia had worked in conjunction with FPT to develop an oil specifically for a low friction design and MultiAir. When I collected my car after it was "repaired" and enquired about the oil used I was told that they used the same oil in all of the cars across the three franchises they held.
After collecting it I was not happy with how it drove and when I mentioned this in a post a forum member with an in depth, Fiat technical background stated that it was essential that the correct oil was used as the multiair solenoids were operated by engine oil and to work correctly they needed the correct oil.
He also stated that in the event of an engine problem Fiat would require an oil sample for analysis before authorising any warranty claims.
So, as I warned in my original thread, any TA owners taking their cars for man oil change would be well advised to ask beforehand what oil will be used and make sure that it is the corect Selenia product (or the equivalent) used.
