Evening Steve! Thank you for your attention. The thing is I imported 2018 TA 85HP from Japan, it has no service records. It looks quite well maintained. 116000 KM on the clock. The thing is when I was looking for the oil specs I found that facelift version 500 are Euro 6 and take 0W30 but when I went to official Fiat dealer's service center THEY INSISTED that it's Euro 5 and put 5W40 Selenia. I'm really confused, TA engine Fiats were never sold in my country and I'm not sure if I can trust Fiat people at all. What else would you recommend as preemtive maintenance to look out for other than obvious Air filter, Interior filter, Spark plugs. Is there anything weird I need to change that I'm not used to in other cars. I'd rather spend money avoiding later problems rather than everything going to hell and none of the mechanics in my country knowing what to do with TA engine

most of local mechanics who work on fiats told me they won't touch TA.
