On my wife 13 dart her oil life monitors seems to go about 7,000-7,500. We have been running synpower 5w40 if we follow the olm it will throw a code for low oil pressure. I saved the code I thought on Alfa obd but now I can’t retrieve it. But it was a multi air vva code and the most common cause was low or dirty oil. The oil wasn’t ever low and we just were following the olm. My 2.4 has never done this but her 1.4 does. When the oil is changed it’s fine so the logical thing would be change it sooner. But is there a different oil that would hold up better? Or another reason it would do this? Any thoughts is appreciated.
