And what about oil grade related to outside temperature, something called weather
, sorry to say bro plz donât mind, you dont have any idea about how oil fulfill weather conditions
âWâ is for winter, in very low temperatures it is required such as -20ÂșC or more like -30ÂșC
5w is better than 10w, and 0w better than 5w in too much cold weather while on working engine at 100ÂșC temperature is important to follow viscosity of the oil which is the oil resistance to flow the oil such as 20, 30, 40, and 50
And sadly 20 and 30 both are not suitable for Pakistani weather, because 30 viscosity works properly when outside weather temperature is maximum 35ÂșC but in lahore it reaches upto 50ÂșC
So, i will suggest only 0w-40, 5w-40, 10-40 which anyone could find easily and fully synthetic is better one
