As most of the time the members discuss removing CAT.
I further want to know the reasons for its choking. As almost all vitz are comng from Japan and supposedly with on average 50,000 km on the clock. It seems that quality of fuel/petrol in Japan is even worst than Pakistan, that these CATs get choked.
I have vitz 2001 (A/T), bought it at 53,000 km on the clock. Now on 71,000 km, running on petrol, the CAT working fine even using Pakistani petrol, Average 18.2 km/litre without AC in city and 16.5 km/litre with AC.
Is there any suggested mileage when it gets choked keeping other things constant?
