I have a Suzuki Mehran 2010, and it is consuming a lot of petrol. The fuel average is extremely low, less than 3 km per liter. The engine feels fine, but the fuel consumption is very bad. I usually drive in 1st or 2nd gear due to broken and pothole roads.
I want proper tuning and inspection to fix the fuel consumption issue. Please guide me to a reliable and experienced mechanic or workshop in Karachi who can diagnose and tune Mehran properly. I am looking for genuine advice and shop recommendations only.
