it must be zic x710w40 i guess, first of all this is for all people jo b used cars buy karien. please little bit of maintenance history gari ki zarur lien. ask them about their mechanics electricians oils etc konsa dalwate hain etc etc. If you still have the previous owner number ask him about the engine oil.
In some cases engine oil ka brand change karney sey b cold me gari thora smoke karti hai. but with the time smoke khatam ho jati hai. Or you might need new rings for the engine.
Hows the engine performance? If you just bought the car. tuning karwa lo is ki agar nahi karwai hui... hopefully it will be alright.
