In which bike you are using it. its 700ml so probably 70cc but which model year & brand. And brother how much does it costs. Earlier 10w40 was sold as Zic m7 which was poor oil and some of fellows here had bad experience. I don't think it was synthetic oil oil but was sold as synthetic.
I have bought this one for china 70cc brand express bike is nearly 3 years old. I have been continously using AHl oil in this bike but this time thought of trying out this one. It costs 400 for 700ml & 550 for 1lt. This was early zic m5 20w40 but now its available in zic m5 10w50.
