I am using Zic for over 5 years now and never changed it before 6~7000kms with still some strength left... The best for passo or vitz, reasonable rates and better than fake imported or old leftovers oils batches imported!
5000kms are guaranteed in any situation even you are racing or live in hilly areas even..
Zic X7 Fe 5w-20 will save like no other... Best fuel economy and engine sound & smoothness.. Givevit a try and you never use any other oil later..
Full 3ltrs is just perfect for passo or boon.
