I have 2005 Alto 1000cc (Pak Suzuki One non JDM), with 13'' Alloys, 150000 km driven mostly on CNG but now since CNG has vanished i have to drive it on Petrol. It gives me real pain when it runs only 9-10 Km/liter with shifts on decently low RMP (@ 30000. *RPM installed) in city (Rwp/Isb)...at time i decided to sell it out. On last Sunday i get its carb setting with my mechanic ....it gives awsome result i.e. 13 km/l so far, still goin on and im expecting 14km/l. This milage is given on CURRENT Murree Road situation where i stuck up around 1 Hr.
