I have bought a GLI model 2009 late (1 lac 15 thousand running). Its was running good until few days ago my mechanic said the engine oil you are using is not good.
The last owner was using ZIC 20/50 and I was using Shell 20/50.
So I was thinking to use the ZIC or Toyota, which one I should use 10/30 or 20/50?
Can anyone advice which of them is better?
