only u had a jdm car then
btw alto ain't bad car at all its tough in suspension dept engine is bullet prof in water recent rains i saw many "better efi 1000cc" stalled due to water entering the sensors but alto Rain it is built for it
and man use thin engine oil it will work like a charm
a friend is running same setup as my alto but with 92.5 mehran jet
his car gives around 15 in local
and on motorway it gives around 19 kml with 50% A/C and its same as ur model
