I'm using Lucas 5W-40, it's RM59 Per Quartz which needs 4 Quartz in total... Setting aside the price but I have to mention that it increased the engine oil pressure and had consistent oil temperature and there is a huge difference in the lightness of the engine and I'm running into the 7000km region and its still feels nice

Since it's a new car, it's better to start using branded premium oils to protect the engine i would recommend.
