Brother I am using ZIC 5w-20 fully synthetic engine oil, in my 2015 model Vitz, and fully staisfied regarding all aspects.
Regarding ZIC 0w-30, I am not sure and can only recommend where it is specifically written in the car's owners / users manual. 5w-30 engine oil grade is generally mentioned and used. Its a sort of "market ka engine oil grade"!
PSO 5w-30 fully synthetic engine oil is also available, but I haven't experienced it yet. Its cheaper than Total. If found original, then it can also serve the purpose well and can be recommended after Total.
Shell Helix 5w-30 in semi-synthetic, and in Rs. 3800 is not worth spending. Total is still the overall winner IMO!
