Oil capacity in vitz with oil filter change is 3.9 Litres.
I am attaching the Vitz Owner manual. facts regarding oil reduction are mentioned in it by toyota. there is nothing to worry about.
they have suggested oil viscosity of 5w-30 however considering our weather conditions i suggest toyota taglon 5w-50 fully synthetic API SN. you can get it from hamza younis or mehran auto in saddar rwp or toyota 3s dealer ships. (approx Rs 2800-3200 / 4L pack).
