The label on it says "Manufactured for Repco Limited by Mobil Oil Australia Pty Ltd.", and it is rated API CI-4 and SL. However, it only mentions ACEA A2/B2, without other ACEA ratings.

    Why ester based oil can provide better cleaning effect?

    By reading topics on AutoRX and other full syn. oil, it seems to me that the ester in those Group 4+5 engine oil / AutoRX can provide much better cleaning effect compared to base oil from other group. Is it correct and is there any reason that is responsible for that?
