Go For Liquimoly ATF top tec 1800
Suzuki Ciaz Require ATF AW-1. And it is the best oil.
I poured this oil in my Ciaz on 60k KMS and now my car is 1lack 40k. KMS done and believe me after poring this oil my car shifts become silky smooth and performance also increased.
Never ever pour Suzuki AW-1 available on Suzuki dealership it's Japanese and don't suit thiland transmission.
