Newbie to the Scooby World

Hi, as the title says im new to the Subaru World, and I have a Levorg GT. Im from Liverpool, UK and so far loving the car. I brought it saturday just gone, it does have a service history which stops at 43K, its currently at 83K.. im not sure if its been self serviced but im wanting to do my own service just to be on safe side

What do I need do? I know how to do one, just list the right oil to use and anything else

Cheers

Welcome.
I have a 2litre sti and online says 0w20 oil. My oil cap says 5w30. It's an fa20 engine in mine and personally I think 0w20 is to thin.
I use 5w30 shell helex ultra and I use a genuine subsru filter.
any stock panel filter will do, but I went for the washable pipercross one.
Cvt fluid i used tutela multi cvt 700 as they claim to be better than oem.
I havent done my diffs yet.

was using 0w20 for ~120kkm, then changed to 5w30 when she started using some oil. no issue since (at 195kkm).
maintained by subaru dealer.

Huge thank you, my cap says 0w20 and also think this is a bit too thin. Will see how 5w30 goes, seen on other forums people suggest that grade
