Thanks for responding
I am adding bit detail of my vehicle condition:
Car: Suzuki Alto VXL 2024
Reading: ~3,500 km
Fuel Type: Regular petrol
Commute Type: Mostly city driving (Lahore), average speed 25–35 km/h
Trip Length: 8–12 km per trip, mild traffic
AC Usage: Always ON during the trip (since it’s too hot)
With AC: Fuel average drops to around 11–12 km/l
Without AC: I get around 17–18 km/l
This seems like a pretty big difference for a small car. I'm concerned whether this is normal for this model or if there could be an issue with the AC system or tuning.
